Termite Report 2008

Prepared by: Tim Myles, Ph.D. Termite Control Officer

Community Design and Development Services,

Building Services, City of Guelph

April, 2009

i

EXECUTIVE SUMMARY

Guelph‟s Termite Management Areas. Guelph has three Termite Management Areas

encompassing nearly 900 properties on 50 blocks. Red Zone blocks have known termite

infestations while Blue Zone blocks are buffer areas.

Termite Management Progress. In 2008 important progress was made in gaining a better

understanding of the distribution and intensity of termite active areas. Area-wide

suppressive treatments utilized nematodes as a bio-control agent. As well, termite-

specific strains of a pathogenic fungus were isolated, thus providing a second level of

bio-control treatment for the coming season. Much progress was also made with habitat

elimination through yard wood cleanup weekends. Progress in pole management was

made with Guelph Hydro and Bell Canada. Accumulating evidence of persistent

inactivity in several areas should allow us to begin reclassifying some inactive areas and

start shrinking some Termite Management Areas by the end of 2009.

Termite Activity in Red Zone Blocks. An array of 3,000 monitoring traps is installed in

the Red Zone blocks. Traps were inspected by two seasonal staff seven times during the

2008 season from May through October. Termites were discovered in Sector 12 in July,

thus converting from a Blue to a Red Zone block. Of the 20 Red Zone blocks, six blocks

had no detectable trap activity and another six blocks had fewer than 10,000 termites

trapped. Of the remaining eight blocks, five had moderate termite populations in the

range of 15,000 to 38,000 termites trapped, and three blocks had large populations in

excess of 100,000 termites trapped. The total number of termites trapped during the 2008

season was 705,261. Most of the blocks that were previously treated using the Trap-

Treat-Release method during the period from 1999-2001 remain inactive or strongly

suppressed. Current activity in the Woolwich Termite Management Area is mostly in the

blocks north of Tiffany St. The Windermere Management Area remains eradicated over

most of the formerly infested area, with activity found on only one property. The Emma-

Pine Management Area, discovered in 2007, remains quite active.

Approved Mulches. Laboratory tests were conducted to evaluate termite feeding

preferences on a variety of mulch products. Only those mulches which are not consumed

were approved for use. This information was disseminated to termite area residents, local

landscaping and nursery companies, and posted on the City‟s web site.

Yard Wood Cleanup Weekends. Three yard wood cleanup weekends were organized.

The first was held in the area north of Tiffany from August 1-6 and resulted in the

removal of 18 bins and about 30.25 tonnes of yard wood. The second cleanup weekend

was for the south of Tiffany area, with removal of 13 bins and about 26.5 tonnes of yard

wood. The third cleanup weekend was held in the Windermere area, with removal of 4

bins and about 5.5 tonnes of yard wood. A total of 35 bins and 62.25 tonnes of yard wood

were removed, thus greatly reducing the nesting and feeding habitat available for termite

survival and expansion. More targeted cleanups are planned in 2009.

Field Treatments with Entomopathogenic Nematodes. Entomopathogenic nematodes

(parasitic roundworms) were used for area-wide bio-control treatments aimed at termite

ii

population suppression. A commercial preparation of Heterorhabditis bacteriophora was

selected for field treatments. Residents of 129 properties with active traps or near active

traps were contacted and asked to sign a consent form for nematode treatment. Nematode

treatments were conducted from September through October on 98 properties. Ongoing

spring and fall treatments with nematodes are planned in 2009.

Entomopathogenic Fungus Isolated. In 2008, we successfully isolated, from local

termites, two strains of the insect-specific fungus, Metarhizium anisopliae, the causative

agent of green muscardine disease. This will allow us to utilize an additional, safe and

environmental, bio-control agent for termite population control. The number of culture

plates has been scaled up in anticipation of field treatments in 2009.

Treatment of Poles, Posts and Retaining Walls. Permanent wood infrastructure includes

telephone poles, hydro poles, fence posts, road guard posts, park posts, and other items.

Working with Bell Canada, the three Bell poles in the Emma-Pine area were replaced and

the new poles were fitted with Termi-Mesh™ stainless steel pole socks. New policies

have been established for Guelph Hydro operations with respect to pole inspections and

management in the termite management areas. During 2008, Guelph Hydro treated poles

on 65 termite management area properties. Further pole treatments are planned in 2009.

Tree and Stump Removals. Six large city trees or stumps have been removed by the

Operations Department, all from the area north of Tiffany St. Four of these were known

to be termite infested. One large city tree stump was removed at the Emma-Pine area. At

least eight other large mature trees or stumps, on private property, most of which were

known or suspected to be termite infested, were removed at the owner‟s expense. A

dozen or so other trees, with superficial shelter tubes, were sprayed.

Real Estate Inspections and Disposal Permits. Indoor termite inspections are required for

real estate transactions of properties in the termite management areas. Forty real estate

inspections were made during 2008. In addition to organized yard wood clean up

weekends, residents in termite management areas are also able to dispose of yard wood

and demolition debris by obtaining a disposal permit. During 2008, 128 disposal permits

were issued.

Grant Proposal. A grant proposal entitled “Area-wide Management and Eradication of

Invasive Subterranean Termite Infestations” was submitted to the Invasive Alien Species

Partnership Program (IASPP) of Environment Canada. The amount requested for

supplies and equipment was $22,398.00. Confirmation of funding support is expected

soon.

Plans for the 2009 Season. This report will be web posted in early May. Seasonal staff

will start work on May 11th

. Annual meetings with residents have been scheduled for

May 20-21. The plan for the 2009 season includes ongoing population monitoring,

suppressive treatments, and habitat elimination. Suppressive treatments with bio-control

agents including nematodes and/or fungal pathogens will continue. As well, Trap-Treat-

Release with an alternative chemical is planned pending experimental permit approval

from the Pest Management Regulatory Agency.

1.0. INTRODUCTION

1.1. HISTORY OF TERMITE EXPANSION IN GUELPH

The history of termite expansion and management in Guelph was thoroughly reviewed in

last year‟s annual report (Myles, 2008). The expansion of infested blocks is depicted in

Figure 1. The designation of Termite Management Areas, and Red and Blue Zones is

shown in Figure 2. Sector numbers and shown in Figures 3, 4, and 5. In 2008, termites

were discovered on one additional block, Sector 12, as depicted in Figures 2, 3, and 11.

This expansion was in an area which had previously been a designated Blue Zone block

located between two Red Zone areas, and therefore was not particularly surprising. This

raised the number of Red Zone blocks to 20 and lowered the number of Blue Zone blocks

to 27 (Table 1). The low number of active traps and termites trapped suggests that the

termite population on this block is probably quite low at this time, although first year

trapping numbers tend to be low.

1.2. HISTORY OF TERMITE MANAGEMENT IN GUELPH

The history of prior termite management in Guelph was also reviewed in last year‟s

annual report. To recap, from the mid 1970s to 1990 Guelph participated in the

provincially funded grants program which partially covered chemical treatment costs for

conventional soil termiticide treatment of infested homes. Although this gave some

degree of individual structural protection, it failed to suppress the termite populations or

prevent their spread. In 1998 the City contracted the Urban Entomology Program

(University of Toronto) to conduct an area wide survey and termites were found on 12

blocks. From 1999 to 2001 an area-wide control program using an experimental method

called Trap-Treat-Release resulted in the strong suppression or apparent eradication of

termites on most of the 12 blocks plus the Windermere area, which was discovered in

2000. After 2001, spotty activity continued on a few blocks, and new termite activity was

discovered on a number of blocks, especially north of Tiffany St. A one year baiting

project on in 2005 had little impact. In 2007, the City hired Tim Myles, who was

previously Director of the Urban Entomology Program at the University of Toronto, as a

full time Termite Control Officer with a mandate to develop a comprehensive control

project aimed at containment, suppression and eradication of termites on a city-wide

basis.

The year 2007 was devoted to installing a new trap array, and during that year termites

were discovered on two new blocks, including the new Emma-Pine Area. In 2008,

significant progress was made in termite habitat reduction through clean up weekends,

tree and stump removals. As well, in 2008, renewed efforts were made to identify new

control agents for area-wide treatments. Efforts to identify more effective bio-control

agents, included studies on several mites, nematodes and fungus species associated with

termites. Of these, the most promising, appeared to be entomopathogenic nematodes,

which were lab tested and subsequently applied on an area-wide basis. In addition, two

strains of the entomopathogenic fungus Metarhizium anisopliae, were isolated in pure

2

culture. In addition, disodium octaborate tetrahydrate (DOT) and zinc borate (ZB) were

identified as suitable new actives for Trap-Treat-Release.

2.0. MATERIALS AND METHODS

2. 1. COMPONENTS OF THE TERMITE MANAGEMENT PROGRAM

Components of the termite management program included trapping and monitoring,

termite habitat reduction through various types of yard wood management, and termite

population suppressive treatments. In addition, numerous steps were taken to integrate

the program with the operations of other City departments. Such integration included

building permit approvals and inspections through Building Services, landscape permit

planning and approvals through Planning, tree and stump removals by the Operations

Department, yard wood disposal with Waste Management, road construction projects

with Engineering, and soil excavation and disposal with Waterworks. New pole

management protocols were developed with Guelph Hydro and Bell Canada. In addition,

progress was made in announcing the program with Guelph area real estate agents

through the Guelph Real Estate Board, and coordinating inspections for real estate

transactions. A mailing was also done to local nursery and tree service companies

informing them of approved mulches and disposal policies. The program has also been

communicated in the newsprint media, on television, in numerous mailings to area

residents, through annual reports, and other materials posted on the City‟s termite web

page at www.guelph.ca > quick links > termites.

2.2. MONITORING AND TRAPPING

The array of nearly 3,000 monitoring traps that was installed in 2007 was refurbished

with fresh cardboard rolls and marked with new green bamboo marking sticks from May

through June, 2008 (Table 1, Figures 8-29). Additional traps were installed in Sector 12

after termites were discovered there in July (Figure 11). New traps were also installed in

the Blue Zone of the Windermere area (Figure 26). Traps were checked on a 3-4 week

cycle. Most traps were checked 6 or 7 times during the trapping season from May

through October during 2008.

2.3. TERMITE HABITAT REDUCTION

2.3.1. Yard Wood Cleanup Weekends. Following the successful demonstration of the

first Yard Wood Cleanup Weekend, which was held in the Emma-Pine Area in October

of 2007, three Yard Wood Cleanup Weekends were scheduled during the 2008 season

(Appendices 12, 13, 14). The first was held in the Woolwich Management area north of

Tiffany St. from August 1-6. The second clean up weekend was for the south of Tiffany

St. area from August 22-25. The third clean up weekend was held in the Windermere

area, from September 5-8.

2.3.2. Yard Wood Disposal Permits. Under the program, residents in Termite

Management Areas are required to disposal of all yard wood and building rubble at the

http://www.guelph.ca/

3

Waste Resource Innovation Centre. Residents must first call to arrange for a „field

inspection‟ of the material to be disposed and then a „disposal permit‟ is issued which

provides a waiver of tipping fees on the first 250 kg per load. Generally, disposal permits

are good for one week from the date of issue. The amount in excess of 250 kg is charged

at the normal tipping fee rate of $70.00/ tonne.

2.3.3. Tree and Stump Removals. Under the program, termite infested city trees and

stump are removals by the City‟s Operations Department. The costs of removal and

disposal of infested trees on private property are the responsibility of private owners.

2.3.4. Utility Pole Management. TermiMesh is a marine grade stainless steel physical

barrier that can be fabricated into pole sock to protect the base of wood poles in the

ground. In 2008 TermiMesh pole socks were fabricated and fitted to three new

replacement Bell Canada poles in the Emma-Pine termite management area. Impel borate

rods may be used to treat poles, post or fence posts in service. Borate wraps are another

approach to pole treatment. During 2008, discussions with Guelph Hydro established new

pole inspection and management protocols in the termite management areas (Appendix

19).

2.3.5. Posting of Termite Warning Signs. At one of last year‟s public meetings it was

suggested that signs should be posted in certain areas to raise public awareness and to

prevent the spread of termites. Thus a termite warning sign was designed and fabricated.

Six such signs have been posted in areas where it is hoped to limit the dumping or

removal of termite infested material (Figures 32 and 33).

2.3.6. Mulch Feeding Preference Studies. Lab studies were carried out to evaluate termite

feeding preferences on various mulch products to identify mulches satisfactory for use in

termite management areas (Appendix 20).

2.4. POPULATION SUPPRESSION

2.4.1. Population Suppression by Reductive Trapping. Monitoring traps were checked on

approximately a 3-4 week cycle. Infested cardboard rolls were retrieved from traps and

replaced with new rolls. Infested rolls are taken to the termite lab at Riverside Park where

the termites are extracted and weighed to determine the number collected. The number of

active traps and number of termites trapped were recorded daily.

2.4.2. Evaluation of Commercial Entomopathogenic Nematodes. Three species of

commercially available entomopathogenic nematodes were evaluated in lab tests for

control of termites: Capsanem® (Steinernema carpocapsae), Entonem® (Steinernema

feltiae), and Terranem ® (Heterorhabditis bacteriophora), all products of Koppert

Biological Systems.

2.4.3. Field Treatments with Entomopathogenic Nematodes. The commercial preparation,

Terranem® (Heterorhabditis bacteriophora) was selected for field application.

Residents of 129 properties with active traps or near properties with active traps were

4

contacted and asked to sign a consent form for nematode treatment. Nematode treatments

were conducted from September through October on the 98 properties that returned

consent forms. Application rates were generally 100,000 per property but ranged up to

200,000 infective juveniles per property, depending on property size and termite activity.

Nematodes were applied by watering can in the vicinity of active traps and other areas of

suspected termite activity near stumps, large trees and garden margins. Nematodes were

generally not applied to lawns.

2.4.4. Investigations of Other Potential Bio-control Agents. Several species of naturally

occurring and apparently termite parasitic nematodes were isolated from termite cultures

and identified. In addition, two strains of the entomopathogenic fungus, Metarhizium

anisopliae, designated Guelph-RF-08a (with green conidiospores), and Guelph-RF-08b

(with dark greenish brown conidiospores), were isolated from termite cultures and

cultured on Potato Dextrose Agar (PDA).

2.5. CHEMICAL TREATMENTS

2.5.1. Soil Termiticides. Registered chemical actives for termite control in the US and

Canada were reviewed in last year‟s report (Appendix 19 & 20). The only soil termiticide

registered in Ontario is permethrin (Dragnet®) (PMRA, 2007a). Permethrin soil

termiticide may be used for pre-construction treatment, preventive, or remedial treatment

of the soil beneath the foundation and around the footings of a structure. Soil termiticide

applications provide a long lasting toxic barrier in the soil which kills any termites in the

treated soil and repels termites from accessing the treated structure. Soil termiticide may

also be used for treatment of soil at the base of sheds, retaining walls and trees. Soil

termiticides may only be applied by licensed operators. The two companies operating in

the Guelph area are Orkin (519-623-5752) and Tepeco (519-653-0441), both located in

Cambridge.

2.5.2. Crack & Crevice Spray. There is only one do-it-yourself spray product that

residents may purchase for treating termites in Ontario. This product is Konk 400® with

Baygon (propoxur) (PMRA, 2007b). This is a crack and crevice treatment product for

direct application to termite infested wood or foundation cracks and crevices where

termites may be entering a structure. This product can only be recommended where the

point of entry and the extent of termite workings in a structure have been exposed and

traced out. This product would not provide adequate treatment in the case of more

extensive structural infestations. This product is available locally at the TSC Store at

Woodlawn and Silvercreek.

2.5.3. Wood Preservatives. Wood preservatives deter wood rotting fungi and wood-

feeding or burrowing insects. Heavy duty preservatives such as creosote and

pentachlorophenol are used for the treatment of the bases of utility poles and rail ties. The

most widely available treated wood, known as „pressure treated‟ is green in color and

treated with copper based formulations. Alkaline Copper Quaternary (ACQ) has

generally replaced Chromated Copper Arsenate (CCA) (EPA, 2008). However, many

instances of termite infestation of untreated cores of pressure treated wood have been

5

observed in Guelph termite management areas. Therefore pressure treated wood is not

recommended for in-ground use in Guelph termite management areas. Under the Ontario

Building Code, in termite infested areas, outdoor wood elements must be supported on

concrete piers at least 5⅞ inches in height, and any wood element extending from 5⅞

inches to 17¾ inches must be pressure treated. Cut ends of pressure treated lumber must

be treated with end cut preservatives (copper naphthenate in ground contact or zinc

naphthenate above ground) (PMRA, 2006a). Borate wood preservatives may be used for

indoor construction, where the wood will not be exposed to moisture. The primary active

ingredient for borate treated wood is disodium octaborate tetrahydrate (DOT). Borate

pretreated wood is available as BluWood®. Remedial or preventive treatment of indoor

wood may be done by licensed operators using TimBor Professional ® (containing DOT)

(PMRA, 2007c). Remedial treatment of outdoor infested wood posts or retaining walls

may be done with Impel ® boron rods by licensed operators.

2.6. INSPECTIONS

Various types of inspections are performed as part of the termite control program by the

termite control officer. The most important inspections are for sale of property, prior to

closing real estate transactions. These inspections must be requested by the owner or

seller‟s agent. The termite inspection reports should be requested by the prospective

purchaser or purchaser‟s agent. The most common type of inspection are field inspections

for material disposal. Residents should arrange these whenever disposing yard waste,

debris, or building rubble. Yard and indoor inspections are also performed on any areas

of newly discovered infestation. From time to time, inspections are arranged with

residents to confirm inactivity in certain areas. Inspections may also be requested to

evaluate the extent of damage and recommend control measures. Inspections are also

performed during removal of trees to determine whether or how much of the tree must be

disposed at the landfill, or how much may be salvaged and disposed elsewhere or used as

firewood. Inspections are done during soil termiticide treatments, and when treatments

are prescribed for pre-construction treatment in a building permit. Inspections are done

for demolitions, or for new construction or additions such as decks, porches in termite

management areas. Courtesy inspections are also performed inside or outside termite

management areas to examine any questionable structural damage and identify any

suspect insects. Inspections are also conducted in conjunction with City road work

projects that border on termite management areas. Adjacent trees are inspected for

evidence of termite shelter tubes, and the sub-surfaces under asphalt and sidewalks are

inspected to ensure that there is no evidence of termite tunnelling or nesting, before

asphalt and concrete are cleared for disposal.

2.7. COMMUNICATIONS

In 2008 various efforts were made to extend communications about the termite program

to residents and to improve the integration of termite program with various other City

departments. A one-page General Information Sheet on the termite program was

developed. Various memoranda were written up clarifying operating procedures with

other departments. Website content was expanded to include new information about the

6

program as well as photos and movies of termites to assist residents in termite

identification. Communications with residents, Bell Canada, Guelph Hydro, Guelph Real

Estate Board, Guelph Waterworks, landscaping companies, and newspapers are included

in the Appendix.

3.0. RESULTS & DISCUSSION

3.1. PATTERN OF BLOCK ACTIVITY

Of the 20 Red Zone blocks, there were seven blocks with no detectable trap activity and

another five blocks had fewer than 10,000 termites trapped. Of the remaining eight

blocks, five had moderate termite populations in the range from 15,000 to 38,000 termites

trapped, and three blocks had large populations in excess of 100,000 termites trapped.

The total number of termites trapped during the 2008 season was 705,260 (Table 2). Most

of the blocks that were previously treated using the Trap-Treat-Release method during

the period from 1999-2001 remain inactive or strongly suppressed. Current activity is in

the main termite management area is mostly in the blocks north of Tiffany St. Of the

other two management areas, the Emma-Pine Management area remains very active,

while the Windermere-Inverness Area remains eradicated over most of the former area of

infestation with only a very small pocket of activity found on one property.

3.2. TERMITE HABITAT REDUCTION

3.2.1. Yard Wood Clean Up Weekends. Three yard wood cleanup weekends were

organized. The first was held in the area north of Tiffany from August 1-6 and resulted in

the removal of 18 bins and about 30.25 tonnes of yard wood. The second clean up

weekend was for the south of Tiffany area, with removal of 13 bins and about 26.5 tonnes

of yard wood. The third clean up weekend was held in the Windermere area, with

removal of 4 bins and about 5.5 tonnes of yard wood. A total of 35 bins and 62.25 tonnes

of yard wood were removed, thus greatly reducing the feeding, nesting, and expansion

habitat available of termites.

3.2.2. Tree and Stump Removals and Surface Treatment of Trees. Six city trees or stumps

have been removed by the Operations Department all from the north of Tiffany area.

Four of these were known to be termite infested. One large stump of a city tree was

removed under contract at Emma-Pine. At least eight other large mature trees or stumps,

on private property, most of which were known or suspected of being termite infested

were removed at owners expense. A dozen or so other trees with superficial shelter tubes

were sprayed.

3.2.3. Treatment of Poles, Posts and Retaining Walls. Permanent wood infrastructure

includes telephone poles, hydro poles, fence posts, road guard posts, park posts, and

miscellaneous other items. Where residents possess the financial means, it has been

recommended that retaining walls or dilapidated wood fences be removed, and many

residents have voluntarily compiled. However, the remaining in-ground wood

infrastructure remains a concern as potential termite habitat. Neither creosote treatment

7

nor pressure treatment of wood seems entirely adequate as both types of wood in service

have been found with termite damage. In the Emma-Pine Management area, three old

telephone poles were identified with termite shelter tubes. Bell Canada was consulted

regarding how best to manage this situation. It was decided to replace the poles and refit

new poles with specially fabricated TermiMesh stainless pole socks. This process was

complicated and somewhat costly. The City and Bell split the costs. TermiMesh pole

socks are not a financially sustainable approach in the long term.

3.2.4. Utility Pole Treatments. Hydro poles are among the in-ground wood infra-structure

that require preventive management. Fortunately, several levels of protection are already

in place due to ongoing Guelph Hydro pole management (John Saunders, personal

communication). Firstly, Guelph Hydro has been using poles of naturally resistant woods,

primarily, western red cedar and Douglas fir. Secondly, poles butts since 1992 have been

treated with pentachlorophenol. Thirdly, their pole testing program is set up on a four

year cycle that tests one third of the city each of the first three years and on the fourth

year test the whole city for poles recommended for retest. The Guelph Hydro pole testing

program started off testing poles that were twenty years or older and has since been

expanded to all poles in the Termite Management Areas. In addition to testing, Guelph

Hydro has started treating all poles in the termite zones with boron rods and in 2009 will

expand this treatment program to poles with center rot or carpenter ants. A new aspect of

the program will be small pole tags at eye level indicating danger poles, boron rods or

pole treatment. In March, 2009, new policies for pole management and for disposal of

excavated soil and used poles were established with Guelph Hydro to cover their

operations in the Termite Management Areas (Appendix 19). A total of 65 poles in the

termite management areas were treated either with boron rods or borate wraps by Guelph

Hydro in 2008 (Table 4).

3.2.5. Approved Mulches. Laboratory tests on termite feeding preference on a variety of

mulch products were conducted. These studies enabled us to draw up a list of approved

and unapproved mulches. Approved mulches include all non-organic mulches such as

decorative stone and Rubberific mulch; as well as organics such as cocoa bean mulch,

coconut husk, and pine bark nuggets. This information was disseminated to termite area

residents and local landscaping and nursery companies. This information was also made

available on the City‟s termite web site.

3.3. POPULATION SUPPRESSION

3.3.1. Reductive Trapping. A total of 705,261 termites were trapped from the termite

management areas during 2008 (Table 2). As expected, this was a sharp increase over

2007, which was only a partial season with the traps installed in mid-season of a dry year.

Since no Trap-Treat-Release was performed in 2008, the trapped termites were not

returned to the field. Thus their removal constitutes a partial reduction of the field

population.

3.3.2. Lab Evaluation and Field Treatments with Entomopathogenic Nematodes.

Laboratory tests of three commercial species of entomopathogenic nematodes (EPNs)

8

were conducted to determine the most appropriate species for termite control. All species

caused significant termite mortality. Relative efficacy was determined as follows:

Heterorhabditis bacteriophora > Steinernema carpocapsae > Steinernema feltiae.

Properties with active traps or near active traps were contacted and asked to sign a

consent form for nematode treatment. Nematode treatments were conducted from

September through October. This was too late in the year to evaluate a population

decline, which may become measureable by the end of the 2009 season.

3.3.3. Isolation and Culture of Entomopathogenic Fungi. Two species of fungi are of

interest as potential termite-specific pathogens, Antennopsis gallica and Metarhizium

anisopliae. The epiparasitic fungus, Antennopsis gallica, is normally present at very low

infection levels but has been shown to be lethal at high infection loads. This fungus was

found to be of common occurrence on termites in Guelph.

Two strains of the entomopathogenic fungus Metarhizum anisopliae were isolated from

termite collected in Guelph. Metarhizium anisopliae was been used to control many

insect pests (PMRA, 2006a) and was registered in the United States for termite control, in

a product called BioBlast. The two Guelph strains have been maintained in culture on

Potato Dextrose Agar (PDA) plates. Both strains produce adequate quantities of conidia

(spores). At two months after inoculation, the lighter green strain grows slightly more

slowly, producing on average about 571.5 mg (wet weight) conidia while the dark green

strain produces about 635 mg of conidia within a two month period. With over 100 plates

in culture, sufficient conidia have now been produced for treatment needs during 2009.

Thus, Metarhizium treatments, in addition to the nematode treatments, may provide a

second level of area-wide bio-control for the 2009 season, provided that the appropriate

federal experimental research permits can be obtained from the Pest Management

Regulatory Agency of Health Canada.

3.4. COMMUNICATIONS

3.4.1. Mailings. Several mailings went to residents of the three termite management

areas (Appendices 7, 12, 13, 14, 15, 16, 17, 18). Other letters and notices were sent to

Guelph Real Estate agents (Appendix 8), Bell Canada (Appendix 10), Guelph and area

landscaping companies (Appendix 11), and Guelph Hydro (Appendix 19).

3.4.2. Media Coverage and Newspaper Notice. Several newspaper articles reported on the

termite program‟s progress (Appendices 1,2 & 4-6). A notice was placed in the Guelph

Tribune (Appendix 3) alerting Guelph residents of the possibility of termite infestation

and directing them to further information on the City‟s web site. The hope is that this will

help to raise awareness and thus limit the accidental spread of termites.

3.4.3. Termite Web Site. New materials were posted on the City‟s termite web site at

www.guelph.ca > quick links > termites. An introductory section on general information

about the termite program if followed by reference materials including the 2007 report,

maps of the Termite Management Areas, and termite videos.


9

3.4.4 Inspections and Field Reports. In addition to organized yard wood clean up

weekends, residents in Termite Management Areas are also able to dispose of yard wood,

and demolition debris by obtaining a field report & disposal permit from the termite

control officer. During 2008, 128 field reports were issued. Forty real estate inspections

were made during 2008. Inspections or visits are also conducted on all properties that

have been issued a building permit, for renovations or additions; about 15 such

inspections were done in 2008.

3.4.5. Insect Identifications. Numerous Guelph residents both inside and outside the

termite management areas have called with concerns about suspected termite activity or

other unknown insects. In most cases these have involved wood boring beetles, powder

post beetles, anobiid beetles, bark beetles, dermestid beetles, rove beetles, citronella ants,

carpenter ants, pavement ants, flying ants, mud daubing wasps, or sowbugs. One case

also involved a severe infestation of bed bugs.

3.4.6. Grant Proposal. A grant proposal entitled “Area-wide Management and Eradication

of Invasive Subterranean Termite Infestations” was submitted to the Invasive Alien

Species Partnership Program of Environment Canada (Appendix 21). The amount

requested for supplies and equipment was $22,398.00.

Important Notice To All Guelph Area

Real Estate Agents

March, 2008

Real Estate Agents are responsible for the following:

Know where the three Guelph Termite Management Areas are located.

Ensure disclosure that a property is located within the Termite

Management Area.

Ensure the property has a termite inspection.

Ensure that prospective buyers are provided a copy of the termite

inspection report.

Ensure that prospective buyers are aware that the City of Guelph has a comprehensive Termite Control Program with which residents in Termite

Management areas must comply.

Please see the attached “General Information on Termites in Guelph” and the

map showing the locations of the three Termite Management Areas.

Appendix 9.

General Information on Guelph’s Termite Management Program

Subterranean termites are non-native invasive insects that can cause serious structural damage to

homes and can be difficult and expensive to control. These insects have been accidentally

introduced from the United States to over 30 Ontario municipalities. The termite infestation in

Guelph was first detected in the early 1970s near Goldie Mill Park. Currently, in Guelph, there are

three designated Termite Management Areas, all on the north side of the City, encompassing 869

properties.

New infestations can become established by the movement of infested wood or soil. Therefore, all

residents of the City should be cautious about donating or receiving any wood items that have been

sitting outdoors on the ground, such as firewood, landscaping ties, wood sheds, mulch, etc.

Residents in Termite Management Areas are required to comply with strict disposal procedures to

restrict the potential spread of termites to other areas of the City. The disposal procedure is as

follows: 1) stack wood in a pile or load wood in a bin in preparation for disposal, 2) call 519-837-

5614 to set up an inspection, 3) the Termite Control Officer will inspect and write a field report, 4)

deliver wood to transfer station at 80 Dunlop Drive and present field report to waive tipping fees on

the first 500 pounds.

When selling a property in a Termite Management Area, the resident or agent is required to disclose

that the property is within a Termite Management Area, obtain a termite inspection report from the

Termite Control Officer, and ensure that prospective buyers receive a copy of the inspection report.

The owner should arrange an inspection by calling 519-837-5614. If the agent arranges the

inspection then a written request from the owner must also be faxed or delivered to Building

Services, 2 Wyndham St. N., 2nd

Floor, (fax: 519-822-4632).

Landscaping, renovation and new construction can also be affected in termite areas. New fences

should be constructed of non-wood materials or if wood posts are used they must be pressure treated

and supported on metal brackets above ground level. Likewise, retaining walls must be constructed

of non-wood materials, not pressure treated wood. In addition, the Ontario Building Code has

specifications for construction of new buildings, porches, and decks that pertain to termite infested

areas.

Under the direction of the Termite Control Officer, the City has a comprehensive strategy for termite

management and control. This involves inspections, monitoring properties with traps, reduction of

termite habitat through yard wood management, area-wide colony level suppressive treatments, and

limited utilization of conventional chemical treatments where necessary.

For further information and maps of Termite Management Areas please visit http://guelph.ca > quick

links > termites or contact Dr. Tim Myles, Termite Control Officer, [email protected].

390 Tower St. South

Fergus, Ontario

Tel: (519) 787-7711 RE: Termite Infested Poles in a Guelph Termite Management Area

The City of Guelph currently has three termite management areas in which the City

is attempting to eradicate termites (see maps at Guelph.ca > quicklinks > termites).

One of these areas, at Emma St. and Pine Dr. was recently discovered in September,

2007. The population in this area appears to be quite strong. We are attempting to

eradicate termites in all areas through a combination of colony level treatments,

chemical treatments of infested structures, and yard wood management.

We have discovered that the wooden telephone pole in the backyard at 8 Pine Drive

is infested. Furthermore, two other old wooden poles, in the back yards or 126 Emma

and 14 Pine are likely to also be infested below ground level or become infested

(see attached map). Therefore, I request your cooperation in undertaking the removal

of these poles and their replacement with either concrete poles of a subterranean line.

Please contact me at you earliest convenience so that we may discuss appropriate actions.

IMPORTANT NOTICE

TO ALL GUELPH AND AREA

LANDSCAPING COMPANIES

The City of Guelph is proactively working with residents in the Termite Management Areas in the City of Guelph to control the spread of termites. This

notice provides information to landscaping companies who may be doing work in these areas.

Landscaping companies are responsible for the following:

Know where the three Guelph Termite Management Areas are located (mapping attached);

Do not deliver wood chip mulch to these areas [cocobean mulch or

decorative stones may be used];

Do not install wood retaining walls in these areas;

When removing any stump or other wood materials from these areas

follow the prescribed Disposal Procedures for Termite Management Areas (attached);

Follow instructions on City of Guelph web site [Guelph.ca – quick links –

termites] for construction of wood fences or decks in the Termite Management Areas;

Contact the City’s Termite Control Officer if you have any questions [519-

837-5615, ext. 2840].

Termite Management Area Residents (North of Tiffany Street)

Yard Wood Clean Up Weekend and Update on Mulches

The purpose of this letter is two-fold:

To announce the upcoming Yard Wood Cleanup Weekend.

To provide information on approved mulches.

Yard Wood Cleanup Weekend – Friday August 1st to Monday August 3rd

Disposal bins will be located throughout the Red Zone for the residents to use. Adjacent Blue Zone residents are also encouraged to participate. Please see the reverse side of this letter for a map of the planned locations for the bins (actual locations may differ slightly).

The bins will be delivered on the morning of Friday, August 1st and picked up on the morning of Monday, August 4th. The bins will have parking permits, signage, and barriers. If the bin nearest you fills, then use another. If all the bins fill, leave excess material on your property or drive, well back from the curb, and we will assist in disposing of it later.

Yard Wood Management is an important aspect of the City’s termite control program. Dead wood in soil contact provides termites with feeding, breeding, and overwintering habitat. Our primary focus this year is on removable items such as: wood chip mulch, edging boards, retaining walls, fire wood, sheds, scrap lumber, planting barrels, dead trees, and stumps. Wood chip mulch should be raked up and bagged in clear plastic bags in preparation for disposal.

Some dead wood, such as boards or firewood, can safely be retained if stacked properly off the ground on asphalt, concrete, patio stones or concrete blocks. Fence posts and utility poles are not the focus at this time. Live trees and branch trimmings are also not generally attacked by termites and should not be disposed, at this time.

Red Zone residents will be provided a map and list of yard wood items which should be removed from your property. This will be left in your mail box by termite program staff prior to July 25th. Termite program staff will be on hand on Friday August 1 to assist with removal. Over the weekend, it is hoped that neighbours will assist each other in the disposal task. This is an important opportunity to collectively reduce termite habitat, so please try to remove as much yard wood as possible.

Approved Mulches (Decorative Stone, Rubber Mulch, Pine Nuggets, Cocoa Shells, Bark, etc.)

After you have raked up and removed your old wood chip mulch you may want to apply new mulch or ground cover. I have attached a chart summarizing the outcome of a recently completed study of termite feeding preferences on various mulches, indicating which mulches have been approved or not approved for use in the termite management area.

Thank you for your participation in this community project!

The purpose of this letter is four-fold:

To notify residents of newly discovered termite activity in the area

To announce the upcoming Yard Wood Cleanup Weekend on September 5-8

To notify residents of indoor inspections from September 8-19


Newly Discovered Termite Activity

On July 4, termite activity was discovered in two traps in the front yard of 9 Windermere Court. The pressure-treated wood landscaping ties near the infested traps were also found to be infested and have now been removed. Of the nearly 300 installed traps in the Windermere-Inverness Termite Management Area, these were the only ones that have been found to be active so far this year. It is hoped that the termite activity may be quite localized. However, since the goal of the program is area-wide termite eradication, I feel that it is necessary to take additional measures to limit the survival and spread of this remaining population.

Yard Wood Cleanup Weekend for first weekend of September– Sept. 5-8

As in the other Termite Management Areas of the City, a Yard Wood Cleanup Weekend will be scheduled for the Windermere-Inverness Area. Disposal bins will be located at four locations as shown on the attached map (actual locations may differ slightly). All Red Zone and Blue Zone residents are asked to use the bins to dispose of all removable yard wood in soil contact. The bins will be delivered on the morning of Friday, September 5th and picked up on the morning of Monday, September 8th. The bins will have parking permits, signage, and barriers. If the bin nearest you fills, then use another. If all the bins fill, leave excess material on your property or drive, well back from the curb, and we will assist in disposing of it later. Please do not leave any material on the street outside the bins.

Yard Wood Management is an important aspect of the City’s termite control program. Dead wood in soil contact provides termites with feeding, breeding, and overwintering habitat. Our primary focus this year is on removable items such as: wood chip mulch, landscaping ties, edging boards, retaining walls, fire wood, sheds, scrap lumber, planting barrels, dead trees, and stumps. All stumps and roots should be dug out in preparation for disposal. Wood chip mulch should be raked up and bagged in clear plastic bags in preparation for disposal.

Some dead wood, such as boards or firewood, can safely be retained if stacked properly off the ground on asphalt, concrete, patio stones or concrete blocks. Fence posts and utility poles are not the focus at this time. Live trees and live branch trimmings are not generally attacked by termites and should not be disposed, at this time.

Residents will be provided a map and list of yard wood items which should be removed from your property. This will be left in your mail box by termite program staff no later than August 29. Termite program staff will be on hand on Friday September 5 to assist with removal. Over the weekend, it is hoped that neighbours will assist each other in the disposal task. This is an important opportunity to collectively reduce termite habitat, so please try to remove as much yard wood as possible. To be included in the Yard Wood Clean up will be the removal of all wood landscaping ties, regardless of whether they have been pressure treated or treated with borate rods. In addition all wood sheds must either be placed on a concrete pad, or elevated on blocks, or dismantled in preparation for disposal. Residents are also reminded that up to 500 pounds of yard wood may be removed per trip at any time of year. To arrange this, call the inspection line at 519-837-5614 to set up a “material disposal inspection”. You will then be issued a field report with a tipping fee waiver to take to the weigh scales at the public drop off at 80 Dunlop St. For further information see Disposal Procedure at: Guelph.ca > quick links > termites.

Indoor Inspections will be conducted the 2nd and 3rd weeks of September In addition to the yard inspections and ongoing yard monitoring of yard traps, we will also be doing indoor inspections of all Red and Blue zone properties. Residents will be called to arrange an inspection time, between 7am and 3pm. These inspections take approximately 15 minutes. In the event of the discovery of indoor infestation, renovations or treatment will be recommended.


After you have raked up and removed your old wood chip mulch you may want to apply new mulch or ground cover. I have attached a chart summarizing the outcome of a recently completed study of termite feeding preferences on various mulches, indicating which mulches have been approved or not approved for use in the termite management area. If you have any questions feel free to contact me or the Chief Building Official, Bruce Poole, at any time. Thank you for your participation in this community project! Tim Myles, Ph.D.

Dear Resident:

Re: Discovery of a termite infestation in your block

This letter is to inform you that last week a termite infestation was discovered in a dead cherry

tree that was removed from a property on the north side Pipe Street. Since the block was already

in the Blue Zone of the Termite Management Area, this discovery is not especially surprising.

Your block will now convert to a Red Zone Block (see attached map).

As you may know, the City has been managing termites in the area for several years. Recently

there has been a renewed effort with the hiring last year of a full time Termite Control Officer.

A detailed history of the termite infestation and various management efforts over the years is

available on the City‟s web site at http://www.guelph.ca > quick links > termites > Termite

Report 2007.

Under the City‟s Termite Control Bylaw, the Termite Control Officer is empowered to enter and

inspect properties to investigate for termites and to prescribe measures aimed at controlling and

limiting the spread of termites.

The following management steps will be taken:

Yard inspections

Trap installation

Yard wood clean up weekend (Aug 1-5)

Ongoing monitoring on approximately a 2-3 week cycle to end of November

Trapped termites will be removed and/or used for colony level treatments

Indoor inspections will be scheduled later in the year

Yard inspections and trap installation: Termite traps will be installed on all properties starting at

7:00 AM this coming Wednesday, July 16 and, if necessary, continuing on July 17. Termite

program staff will first knock on your door, and then proceed to conduct a yard inspection and to

install traps. Please leave gates unlocked. Up to ten traps will be installed per property. Traps

consist of a 4 X 6” plastic pipe with a roll of cardboard and a plywood lid. Traps will be buried

about an inch below ground level and marked with a green bamboo stick. A sketch of the

locations of the traps will be left in your mailbox along with notification of any discovered

termite activity in the yard. Staff will not enter or inspect houses at this time.

Yard wood clean up weekend: A separate mailing has recently gone out concerning the

upcoming yard wood cleanup weekend, originally scheduled for Friday August 1- Monday


- 71 -

August 4. Please note that since Monday, August 4 is a civic holiday, bins will not be picked up

until Tuesday, August 5. Please refer to that mailing for a map of bin locations.

Trees: Live trees are not attacked or killed by termites. Termites may however build shelter

tubes on the bark to reach pruning scars or dead branches. Only trees that have numerous dead

branches or severe heart rot need to be removed. Trees that are taken down must also have the

stump removed. Healthy trees with shelter tubes on the exterior bark can be treated chemically.

Short term and long term goals: The goal of the Termite Management Program for this year is to

identify the extent of the infestation and to eliminate as much yard wood as possible. We also

plan to identify any existing structural infestations and recommend appropriate treatments where

necessary to safeguard structures. Our long term goal is to suppress the population by colony

level suppressive treatments with baits, transmissible chemicals, or termite-specific biological

agents (such as parasitic fungi). Using an integrated approach, involving habitat reduction,

population treatments and limited use of chemical treatments, the City plans to achieve area-wide

control.

Cost sharing: The City of Guelph has taken a proactive approach to termite management with

the ultimate goal of eradicating termites from the City. This however, does not mean that the

City assumes any responsibility for termite infestation or that it intends to cover all costs

associated with termite control. Through the Termite Control Officer the City will monitor

termite populations, coordinate control programs, and apply colony level suppression treatments.

The City offers a tipping fee waiver for waste disposal up to 500 pounds per trip, and may also

from time to time arrange for yard waste disposal bins. The city will also remove any dead city

trees or chemically treat any healthy city trees with evidence of shelter tubing. However, costs

associated with treatment or removal of dead trees, stumps, poles, sheds, fences, decks, retaining

walls, or chemical treatment of structures, or structural renovations on private property must be

covered by the property owners.

If you have any questions please feel free to contact either myself or the Chief Building Official,

Bruce Poole. Thank you for your cooperation in managing termites in your area and preventing

their spread.

To: Emma-Pine Termite Management Area Residents

Re: Termite Project Update

Activity remains Confined to Red Zone So far this year, the traps have been checked three times and termite activity remains confined to the Red Zone. Some residents with structural damage have had commercial chemical treatments conducted. Others with minor activity have elected to do spot treatments. All residents should be aware of the chemical options: 1) Chemical soil termiticide treatments can be conducted by licensed private companies, such as Orkin. 2) For minor localized activity, where the point of entry is identified and spread to structural timbers is absent or fully delimited, it may be adequate in some cases to use the do-it-yourself product, Konk 400, available at TSC.

Release Ports to be Installed in Preparation for TTR The monitoring traps which have been installed in your yard are being checked on a 2-3 week schedule. Any termites that are in the traps are removed. When we receive the necessary approvals, we will be using the trapped termites for Trap-Treat-Release treatments of the termite population. In preparation for such treatments we will soon be replacing any active traps with plastic release ports. The release ports have locking lids. Please do not tamper with either the traps or the release ports.

Telephone Pole Removals and Replacements

Three old wooden telephone poles in the backyards of 14 Emma, 8 Emma and 126 Emma will be

removed. They will be replaced with new poles which will be fitted with specially fabricated TermiMesh

stainless socks. The socks have been ordered and this work will be done as soon as they arrive.

Fence Posts to be Treated with Boron Rods Impel boron rods dissolve slowly into wood as it is moistened by precipitation, and deter fungi and wood destroying insects. One rod will be installed per post by drilling a hole near the base, inserting the rod and plugging the hole with a wood dowel. All red zone residents will be contacted before the end of the season to arrange a convenient time to install the rods in your fence posts.

Tree Treatments Last week all trees in the red zone with evidence of termite shelter tubes were chemically treated with the residual crack and crevice spray, Konk 400.

- 73 -

Indoor Inspections of Blue Zone Properties Last year indoor inspections were conducted in all of the Red Zone properties. This year we will also conduct indoor inspections of the Blue Zone properties. These will be conducted sometime between September 22 and October 3. The inspections take about 15 minutes. Residents will be called in advance to arrange an inspection time between 7:00am and 3:00pm. In the event of the discovery of an indoor infestation, remediation or treatment will be recommended.

Follow up Yard Wood Removal Most residents participated in the yard wood clean up weekend last year and at that time much of the surface wood in yards was removed. However, some yard wood remains, such as landscaping ties and wood chip mulch. A follow-up survey of yards will be done and you will be sent a letter identifying specific yard wood items that should be removed. This will be done in the fall, September – November. Up to 500 pounds of yard wood and waste may be disposed per trip without charge. The yard waste must be taken to the transfer station at 80 Dunlop. To obtain the tipping fee waiver, contact me and I will write a Field Report which must be taken to the weigh scales at 80 Dunlop. If you have no means of hauling yard waste yourself, please call and arrange with me for its disposal. Please review the attached Disposal Procedure.

Approved Mulches

I have also attached a chart summarizing the outcome of a recently completed study of termite feeding preferences on various mulches, indicating which mulches have been approved or not approved, for use in the termite management areas. The most recommended ground covers are non-organic materials such as decorative stone or rubber mulch. Among the organic materials the most resistant top mulch materials are cocoa shell mulch, pine bark nuggets and pure bark mulch. The most resistant organic soil amendment materials are peat moss and coffee bean chaff.

If you have any questions, please do not hesitate to contact me. Thank you for your participation in this ongoing community project. The objective is to achieve area-wide termite control and hopefully eradication.

August 12, 2008

Clarification regarding Termite Management Plan

My letter of July 11, left some residents in the area with the impression that the removal of all yard wood

is mandatory for all Red and Blue Zone residents and that full compliance is required by the date of the

scheduled Yard Wood Clean up Weekend, (Sept. 5-8). Please rest assured that at this time none of the

residents in your neighbourhood are being ordered or compelled to comply with the Termite Management

Plan. While your participation is strongly encouraged, please understand that it is voluntary.

Although the Termite Control Officer is empowered under the Termite Control Bylaw to require the

removal of yard wood, I am not trying to run the project on an enforcement basis. On the contrary, I hope

never to invoke the bylaw or to issue an order to comply. My goal is to promote community education

about the pests and to encourage a cooperative effort to eradicate them from your neighbourhood, and our

city

I believe that the project will work best if based as much as possible on enlightened self interest by

property owners and their diligent voluntary compliance. If there are any aspect of the termite

management plan which you feel are inappropriate, excessive, or particularly difficult or costly for you to

comply with, please contact me so that we can explore alternatives or discuss a temporary open-ended

exemption from compliance.

None of the Blue Zone area has ever been known to have termites and does not seem greatly at risk.

Therefore if you are in the Blue Zone and have wood landscaping items that are too difficult or expensive

to remove, feel free not to remove it, at this time. In the future if termites are found closer to your

property, it may be necessary to reconsider the removal of your yard wood.

During the next three weeks I will finalize my recommendations for clean-up measures for those property

owners residing in the Red Zone. I intend to map out the areas of critical concern, and drop off my

suggestions in your mailbox on or before August 29th. All residents in the Red Zone are encouraged to

participate in the Clean-up Weekend to the best of their ability.

If you reside in either the Red or Blue Zone and have concerns about your yard wood situation, or would

like to discuss the clean-up plan and how it affects you, please don‟t hesitate to contact me. I am at all

times open to your feedback and suggestions. The plan is not set in stone and is not being imposed on the

neighbourhood. I am here to work with you and I am open to all suggestions.

Much progress has already been made toward termite eradication in the neighbourhood and it is my hope

that with further efforts for a few more years we will be able to certify the status of the neighbourhood as

termite-free. For such a designation, the elimination of certain major items of yard wood from the Red

Zone (such as wood sheds) is highly desirable.

Thanks again for your input and participation in the project.

Sincerely,

Tim Myles, Ph.D.

Re: Termite Control Treatments with Nematodes I am writing to inform residents of a change of plan with respect to colony-level treatments for termite control. I had earlier suggested that Trap-Treat-Release treatments with a slow-acting chemical would be conducted this year. However, I have not yet been able to obtain the necessary permits for such treatments, so TTR will not be done this year. However, exciting recent laboratory tests have shown that certain species of entomopathic nematodes are effective against subterranean termites. I am therefore planning to incorporate nematode treatments into the overall management project, and plan to conduct the first nematode treatment this fall. I have enclosed an information sheet on the product “Terranem” which is the commercial preparation of the nematode species Heterorhabditis bacteriophora. This species is often used for control of white grubs in lawns but is also effective against various other insects that live in the soil, including subterranean termites. These nematodes are safe for humans, pets and plants, and can be applied without any special regulatory approvals. The record level of precipitation that we have had this summer has resulted in a relatively high soil moisture level, which will help to promote nematode survival and infectivity. The optimum seasons for nematode applications are the spring and fall. Therefore I am planning to conduct spring and fall nematode treatments, which may continue for several seasons. The fall application this year will run from September 15 through about mid October. Treatments will be done in the evenings from approximately 4:30 p.m. and 7:30 p.m. Approximately 100 million nematodes will be applied per property. The nematodes will be applied with a watering can to the soil in the vicinity of active traps, stumps, trees with shelter tubes, mulched areas, and other areas of suspected or probable activity. If the soil in your yard is dry on the day of treatment, your water hose will be used to dampen the areas to be treated. If you are not home at the time of treatment, a sketch will be left in your mailbox after the treatment showing the areas treated. Please avoid walking on the treated areas for at least 24 hours since the nematodes are delicate and can be crushed by your weight, before they get down into the soil. Please continue to water these areas for a week or two after the treatment if the weather remains dry. The treatments will only be done in active areas of the Red Zone Blocks. Only those properties who are receiving this letter are included in the planned treatments. An authorization form is attached to this letter. If for any reason you do not want to participate in the nematode treatments please indicate this by signing on the lower part of the form. Please take a few minutes to do the following:

Read the attached information about Terranem.

Sign and return the form either by fax, mail, or drop off at 2 Wyndham St. N., 2nd floor.

Call Kim Fairfull at 519-837-5614 ext. 2374 to arrange a date and time for your treatment. Your participation is appreciated.

RE: Policies for pole management and for disposal of excavated soil and used poles from Termite

Management Areas

As previously discussed, we are mutually interested in formalizing an agreement concerning Guelph

Hydro operations with respect to wood pole management and disposal of used poles and excavated

soil. We are also implementing a new policy regarding disposal of hydrovaced soil. The new

policies are as follows:

Preventive Treatment of Wood Poles. As with other areas of the City, poles in Termite Management

Areas will be inspected on a routine basis (4 year cycle on all poles over 20 years and all poles in

termite areas). In accordance with your ongoing preventive maintenance program, all poles in the

Termite Management areas will be treated with boron rods within the next 3-5 years. Treatments

will be done in accordance with manufacture‟s specification (3, 6, or 9 five inch rods depending on

diameter of pole). As well, poles showing minor evidence of rot or wood destroying insects, other

than termites, will be treated in the usual manner with a basal wrap treatment and/or copper

naphthenate, in keeping with standard procedures by your subcontractor. Currently this contractor is

Pole Care International ( www.polecare.ca ) using wood preservative products approved in Canada

(current supplier, Sasco Products Ltd. ( www.sasco.ca ).

Treatment of Termite Infested Poles. Upon inspection, any poles showing evidence of termite shelter

tubes or suspected termite damage will be promptly reported to the Termite Control Officer.

Following inspection by the Termite Control Officer, a decision will be made regarding either

removal or treatment of the infected pole, which may involve treatment or replacement depending on

location and severity.

Disposal of Used Poles. All used poles from Red Zone blocks must be disposed of at the Solid

Waste Transfer Station at 80 Dunlop Drive. Poles from Blue Zone blocks may optionally be

disposed elsewhere if inspection by the Termite Control Officer indicates no infestation by termites.

For such inspection, poles must be excavated and the portion below ground and just above ground

must be cross sectioned to expose any evidence of termite galleries. The whole pole should be cut

into six foot lengths for disposal. A Field Report should accompany such disposal. In order to

obtain a Field Report, the driver of the vehicle should contact the Termite Control Officer at 519-

837-5615, ext. 2840, or 519-824-4383 (cell).

http://www.polecare.ca/

http://www.sasco.ca/

- 78 -

Disposal of Hydrovaced Soil. As I understand, virtually all excavated soil from Guelph Hydro

operations is now hydrovaced ( www.badgerinc.com ). It is my professional opinion that the

churning, submersion and abrasion that would result from hydrovacing and the discharging of soil

from hydrovac equipment would result in conditions that would be impossible for termites to

survive. Such soil may therefore be disposed as it would otherwise be for soil excavated from

outside of Termite Management Areas, without inspection by the Termite Control Officer.

Disposal of Excavated Soil. As before, any soil removed by tractor or backhoe would still present a

risk of harboring termites and therefore must be disposed at the Solid Waste Transfer Station at 80

Dunlop Drive, at standard tipping fee rates. A Field Report should accompany such disposal. In

order to obtain a Field Report, the driver of the vehicle should contact the Termite Control Officer at

519-837-5615, ext. 2840, or 519-824-4383 (cell).

Termite Management Areas. These policies apply to all properties within both the Blue and Red

Zones of the three Termite Management Areas. Please see attached maps. The Blue and Red Zones

boundaries may change over time due either to the discovery of new infestations or to control

efforts. Please check the City‟s termite web site annually for any updates at www.guelph.ca > quick

links > termites.

Termite Survival on Various Types of Mulch

Timothy G. Myles, Ph.D. Termite Control Officer

City of Guelph, 59 Carden St., Guelph, Ontario, Canada N1H 3A1

[email protected] 519-837-5615 ext 2840, 519-827-4383 (cell)

_______________________________________________________________

Abstract: Laboratory tests were conducted to identify termite-resistant mulches which could

be used for landscaping in termite infested areas. Termite survival was assessed using the

eastern subterranean termite, Reticulitermes flavipes, in no-choice laboratory feeding tests on

15 mulch and ground cover materials over a 16-week period. Termites starved and mortality

reached 100% by the 11-12th

week on decorative stone, rubber mulch, cocoa shell mulch, and

coffee chaff. The onset of morbidity was slightly slower but mortality also reached 100% by

the 13th

week on peat moss, by the 14th

week on pine bark nuggets, and by the 16th

week on

extra fine bark mulch. Mortality exceeded 80% but did not reach 100% on several dyed wood

chip mulches and cedar mulch. Mortality reached approximately 60% on two mixed bark and

wood chip products. Termites appeared healthy and mortality remained relatively low on two

other color-enhanced wood chip mulches and on the pine wood controls for the duration of the

16 weeks. The most recommendable soil covers are non-organic materials such as sand, pea

gravel, decorative stone and rubber mulch. Among organic materials the most recommendable

ground cover mulches are cocoa shell mulch, pine bark nuggets, and other pure bark products.

Recommendable organic soil amending materials are sphagnum peat moss and coffee bean

chaff. Wood chip mulches, including color-enhance wood chip mulches, and any bark mulch

that includes a mixture of wood chips are not recommended.

Key Words: Isoptera, Rhinotermitidae, Reticulitermes, termite feeding preferences, termite

diet, termite nutrition, termite starvation, termite cannibalism, termite resistant mulch.

Introduction: Yard Wood Management (YWM) is a critical component of area-wide termite

management projects, including the City of Guelph‟s termite management program (Myles, 2008).

This involves the elimination or replacement of all types of yard wood in soil contact which could

serve as feeding resources or nesting habitat for subterranean termites. Wood chip mulch is a

common example of yard wood which is highly conducive to the growth and expansion of termite

populations. Therefore it is desirable to identify alternative mulch, ground cover, and organic soil

amendment products on which termites cannot derive sufficient nutriment or adequate nutrition for

prolonged survival.

Materials and Methods: Termite survival on various mulches was assessed using the eastern

subterranean termite, Reticulitermes flavipes Kollar (Isoptera: Rhinotermitidae) according to a

standard test protocol for termite resistance (ASTM, 1999) with minor modifications. The 15 tested

materials, product names, manufacturers, and descriptive notes are listed in Table 1. In addition to

the test materials, a concurrent control was run using white pine (Pinus strobus) wood blocks

measuring 2.5 X 2.5 X 0.5 cm.

There were five replicates per treatment and control. Each replicate was set up in a Ziploc “Twist „n

Loc” food container (473 ml). Quikrete Premium Play Sand was baked to sterilize and used as the


- 80 -

termite foraging matrix. A 4 oz. Solo cup was filled with dry sand and levelled with a metal edged

ruler to measure an equal volume of sand into each container (213 grams). Twenty-eight (28) ml of

tap water was added to moisten the sand, which was determined to be 5% less than the water

saturation capacity of the sand. A two gram (dry weight) sample of each test material was placed on

top of the sand. Finally, one gram of foraging termites (mixed castes of workers, soldiers and

nymphs) was added to each replicate, which was determined to be approximately equivalent to 313

termites based on the average of three counted subsamples of 100 termites. Termites were taken

from laboratory stock colonies that were healthy at the start of the experiment. The screw cap

container lids were screwed shut and then unscrewed about 1/8 of a turn to allow slight air

circulation.

All replicates were kept on a lab bench top at room temperature (ca. 23°C) for the duration of the

test. Each replicate was observed weekly by removal of the lid and noting the termite‟s condition as

follows: 1) “H”: healthy, tunnelling below surface level with no or few termite on top of sand, 2)

“T”: ten or more termite on top of sand, 3) “M”: many termites on top and some moribund or dead

termites noted, or 4) “X”: all dead. The experiment was allowed to run for 16 weeks at which time

the remaining replicates with live termites were dismantled, the sand spread on a tray, and the

number of surviving termites in each replicate counted. Visual evidence of feeding on the test

materials and plastering of tunnels with test material was also noted (Figure 1 & Table 1).

The percent mortality data were transformed using the angular transformation (arcsine of square

root) to normalize percentage data (Table A16, Snedecor and Cochran, 1967). Bartlett‟s Test for

homogeneity of data indicated that variance was not homogeneous when the seven treatments with

100% mortality were included. Excluding these, a one-way completely randomized ANOVA was

run on mean mortality using CoStat Software (Version 6.0). Student-Newman-Keuls test was used at

the 0.05 significance level to identify non-significant ranges (Table 1).

Results: Tested materials are listed in Figure 1 and Table 1 according to the order in which 100%

mortality was reached or by percent mortality when less than 100%. Mortality from highest to lowest

was as follows: AllTreat Coco Bean Mulch > Intl. Mulch Rubberific Redwood Mulch > Planet Bean

coffee bean chaff > AllTreat Decorative Stone > Nirom Peat Moss > AllTreat Pine Bark Nuggets >

AllTreat 100% Natural Bark Mulch > AllTreat Black Beauty > AllTreat Red Devil > Hillview Cedar

Mulch > AllTreat Cypress Gold > AllTreat Rustic Bark Mulch > AllTreat Canada Red Bark Mulch

> Scotts Classic Black > pine wood control blocks > Scotts Sierra Red.

As shown in Figure 1 and Table 1, the results may be divided into four categories. In the first

category, mortality reached 100% by the 11-16th

weeks. This category included two non-organic

products, decorative stone and rubber mulch, on which there was no visible feeding on the materials

and termites in these tests did not plaster their galleries. This shows that, as expected, when the

termites had no cellulosic food they eventually starved. Even so, the starvation was surprisingly

gradual, with termites starting to mill about on the surface at 3-7 weeks, morbidity setting in from 8-

11 weeks, and complete mortality requiring 12 weeks.

Evidently, cannibalism provides a short term alternative feeding strategy for these social insects, and

a few semi-cannibalized, (and still living!) individuals were observed in most of these tests.

Although a few cannibalized termites were observed, it was apparent that termites are unable to

make a successful long term shift to cannibalism as a means of group survival in the absence of their

normal diet of lignocellulosic food.

- 81 -

It is of further interest to note that termites starved at approximately the same time on three organic

materials: cocoa shell mulch, coffee bean chaff, and sphagnum peat moss, as they did under the

strict starvation conditions of the non-organic materials. This occurred even though the termite

galleries were plastered with dark material indicating that they had ingested these materials and yet

failed to derive any nutritional benefit to prolong their lives. Mortality was delayed on the pine bark

nuggets and the pure bark mulch suggesting that the ingested material, in these cases, probably

included minute quantities of digestable cellulose, yet not a sufficient amount to sustain life.

In the second category, morbidity set in by 13-14 week and mortality exceeded 80% by the 16th

week. This category include three dyed wood chip products as well as cedar mulch. Although it

appears that termites may have eventually died out on these products, they were able to derived

sufficient nutrition to significantly prolong their survival compared to category 1 materials.

In the third category mortality reached about 60%. This category included two AllTreat products,

Rustic Bark and Canada Red, both including a mixture of bark and wood chips. In both tests, three

of the five replicates remained healthy to the end of the test. In the final category all replicates

remained healthy through the duration of the 16 week test. This category included two Scotts brand

color-enhanced wood chip mulches, in which final mortality was not significantly different from the

pine wood control.

Discussion: Prolonged survival means that the termites were able to feed on and derive sustenance

from the mulch material. Shorter term survival means that the termites either starved, derived

inadequate nutrition, or suffered toxic effects on the material.

It was interesting and unexpected that termites feeding on 13 of the 15 tested materials had

significantly higher mortality than on the pine wood control. There seem to be two possible

interpretations for this, either the mulches provided inadequate nutrition for prolonged survival

and/or the mulches were somewhat toxic. The two non-organic materials, decorative stone and

rubber mulch, demonstrated a nearly identical pattern of termite decline, which may reasonably be

interpreted as the starvation sequence. Thus the starvation sequence under the test conditions

appeared to involve the onset of surfacing behaviour at 3-5 weeks, morbidity appearing in the 8th

week and complete mortality in all replicates by the 12th

week. None of the test materials exhibited

a more rapid decline than the slow starvation sequence and therefore we may infer that none of

materials were toxic, or at least not strongly so. Since the time course of termite decline was nearly

identical to the starvation sequence for cocoa mulch and coffee bean, it seems reasonable again to

interpret this as starvation. This interpretation is also consistent with the fact that these materials are

derived from non-vascular plant matter and therefore low in the cellulosic material which

characterizes vascular plant tissue, and cellulose is known to be the energy source for termite

nutrition (Slaytor, 2000).

A slightly slower, but eventually fatal decline of the termites on peat moss, pine bark nuggets, and

fine bark also seems consistent with the interpretation of inadequate nutrition. These materials are

also derived from non-cellulosic and non-vascular forms of plant biomass, high in lignin and, in the

case of bark, secondary plant compounds.

Termites exhibited even slower mortality on several other wood mulch products, yet this mortality

was still significantly higher than in the pine control (e.g., AllTreat Black Beauty, Red Devil,

Cypress Gold, Rustic Bark, and Canada Red and Hillview Cedar Mulch). It is difficult to interpret

the enhanced mortality in these cases as being due to an inadequacy of digestable cellulose, since

these products are substantially composed of wood chips (xylem tissue high in cellulose).

- 82 -

Furthermore, since most of these materials are dyed or “color-enhanced”, the possibility seems to

exist that the dyeing material may lend a slight degree of toxicity to the products. But such

hypothetical toxic effects, in any case, are slight and the onset is very slow. One can assume that

this effect would be even less under field conditions where termites would be feeding on many wood

sources. Therefore what little suppressive effect might exist due to coloring agents might be so

diluted under field conditions as to have minimal effect.

A practical consideration must also enter the decision as to which products to recommend as suitable

in a termite management program. Some of the color-enhanced products induced no significant

depression of termite survival (i.e., Scotts Classic Black and Sierra Red) while others slightly

enhanced mortality. Since it would be impossible to distinguish in the field those that enhanced

mortality from those that do not, it would therefore be impossible to enforce which should or should

not be used. For this reason, some of the materials which did induce higher mortality than in the

control, still can not be recommended at this time for use in a municipal control program. Further

research is needed to clarify the longer term impact of termite feeding on such mulches under

choice-feeding conditions.

From a termite prevention standpoint, the most recommendable materials would be non-organic

ground covers such as sand, pea gravel, decorative stone and rubber mulch. Decorative gravel,

crushed stone, and stone products come in a wide array of particle sizes, colors and textures of both

natural and crushed stone. Such materials allow precipitation to move through to the soil, help to

prevent erosion, are long lasting, and inhibit weed growth. Non-organic materials are ideal for

garden paths and drives and help to prevent the tracking of mud. Although non-organic materials

hold little moisture themselves, by shading the soil and blocking air movement, they do help to

retain soil moisture.

Among the organic materials are included those which tend to be used as ground covers and those

that are used mainly as organic soil amendments. Cocoa shell mulch, pine bark nuggets, and pure

bark mulches are the only organic materials, among the tested materials, that can be recommended

for top mulching in termite infested areas. Sphagnum peat moss and roasted coffee bean chaff are

recommended as organic soil amending materials.

Cedar mulch, though believed by some to be termite resistant, can not be recommended. Also not

recommended are many products which have “bark” in the product name, because many such

products actually contain substantial quantities of wood chips in addition to the bark. Therefore,

only those bark products that are 100% bark, are likely to be termite resistant. See Table 2 for a list

of approved and non-approved top mulches and soil amendments for the City of Guelph‟s termite

control program.

1. Proponent Information

1.1 Project Management Team and Contact Information a) Organization: City of Guelph b) Organization Description:

As the Termite Control Officer for the City of Guelph, my mandate is to contain, suppress, and hopefully eradicate termites from the City of Guelph. We are implementing an innovative, municipality-wide termite control program which incorporates monitoring, trapping, community participation, habitat elimination, bio-control, wood preservatives, and Trap-Treat-Release. These integrated methods have been demonstrated to achieve strong, area-wide suppression of termites while using only minute quantities of pesticide in contrast to conventional soil termiticide treatments which are very pesticide intensive. Although the proposed project is focused in Guelph, it is aimed at generating data and graphics which will be used for producing a strongly visual, web-based Powerpoint presentation which will communicate how similar projects could be initiated in the 30 other municipalities in Ontario, and others termite infested municipalities in Manitoba, Alberta and BC that also have invasive infestations of subterranean termites.

1.2 Organization Type: Government Agency or Crown Corporation (provincial/territorial/municipal)

1.3 Background

a) Experience: Starting in 1990, I directed the University of Toronto's Urban Entomology Program which had primary responsibility for conducting research on methods of colony-level control and a mandate to develop and implement area-wide control programs for the eastern subterranean termite in Ontario. This program raised over $2 million in funding from federal, provincial and municipal sources. I developed several innovative and environmentally friendly methods including sand barriers, biocontrol approaches, baiting and a novel method of delivering slow acting toxiciants directly to trapped termites, called Trap-Treat-Release (TTR). In large scale pilot projects of TTR in the cities of Toronto, Guelph and Pickering we were able to demonstrate block-wide termite control and apparent eradication on most blocks tested. Last year I accepted a position as the Termite Control Officer for the City of Guelph, with the objective of continuing this work to the point of municipality-wide termite eradication. At the same time I have also continued other municipal projects, for various municpalities with an ongoing active project in the City of Innisfil, the northernmost infested municipality in Ontario.

2. Proposal Background

2.1 Location

a) Province/Territory in which the Project will be undertaken: Ontario

b) Project Target Area: The project will take place in the urban environment, and in this respect is probably different from most other invasive species projects. Termite infestations mainly occur in residential areas where they have access to wood frame houses. In Guelph there are three Termite Management Areas encompassing about 900 properties, of which half are buffer area and the other half comprise 20 blocks with known termite activity. Current known activity on active blocks is confined to about 150 properties.

3. Project Overview

3.1 Overview: Subterranean termites are the most destructive wood destroying insect pests of the urban environment in Canada. They are not native to Canada except in southern British Columbia. In Ontario there are over 30 municipalities that have introduced infestations. The City of Toronto is the most severely infested with well over a thousand infested blocks. However many other cities have smaller and more manageable infestations. The conventional control approach is chemically intensive and focused only on individual properties. Large amounts of toxic soil termiticide are used to saturate the soil around the base of the foundation creating a toxic barrier to keep termites out of the structure. Although this method uses large amount of pesticide, it does little to suppress the colony and nothing to prevent it from spreading. In contrast, the focus of this program is to control termites at the level of whole city blocks by using colony level control approaches. This project also integrates prevention, detection, monitoring, low-toxicity chemical methods, and biological methods. Finally, the project will generate educational materials about termite biology, ecology, and reproduction and provide guidelines which would allow homeowners and municipalities to implement similar eco-friendly, large-scale programs.

3.2 Project Rationale (Purpose): The general objectives are to demonstrate how various termite control methods can be used in an Integrated Pest Management approach for area-wide termite control, while minimizing pesticide application, leading to strong suppression or eradication at the level of city blocks. Two cities are currently under management, Guelph and Innisfil, with the objective of achieving termite eradication. This Partnership Program Project will continue focus exclusively on Guelph, with the intention of expanding to other partnering cities over time. It has already been demonstrated that block-wide colony eradication projects can achieve strong suppression of termites at the block-wide scale and that apparent eradication can be achieved on many blocks within a period of about three to five years. However, a new pesticide active is needed for the Trap-Treat-Release approach (earlier pilot projects utilized sulfluramid which is being phased out by 2012 in the US and is not registered in Canada). Lab tests have shown that zinc borate and disodium octaborate tetrahydrate (DOT) are low toxicity borate compound already registered in Canada which can be effective substitutes for sulfluramid. Furthermore, recent tests have shown that entomopathogenic nematodes are effective bio-control agents against subterranean termites. Zinc borate or DOT will be used as the new active in TTR for the first time this season. In addition, other management practices involving habitat identification and removal are also critically important. This is achieved through Yard Wood Management and organizing Yard Wood Cleanup Weekends during which all wood in soil contact is eliminated.

3.3 Communications Plan: The results will be communicated as final reports and Powerpoint presentation via municipal web sites, a Research Bulletin, and letters to termite infested municipalities. A good termite web page is already present for the City of Guelph at http://guelph.ca > quick links > termites. In addition the results will be communicated as a Research Bulletin for the University of Toronto, Cities Centre, which will also be posted online on the Centre for Urban and Community Studies (CUCS) website at http://www.urbancentre.utoronto.ca/. A letter will be sent to the Mayors and Councils of all known termite infested cities in Canada identifying these termite management and control resources.

3.4 Sustainability: Currently most infested municipalities, including Toronto, have no program in place to assist homeowners in dealing with the spreading plague of urban termite infestations. Homeowners tend to let the situation drift until severe infestation or the sale of a property triggers the necessity of conducting an expensive, individual property-specific chemical treatment which has no impact on the spreading infestation. Through demonstrating that there is a better approach, which greatly reduces the amount of chemical applied, and at the same time achieves larger scale and more long lasting control, the project will demonstrate how municipally funded and coordinated projects can implement block-wide projects to eradicate small infestations or to manage larger infestations. By communicating the steps and details of this area-wide approach to termite management, homeowners and municipalities will be provided with the necessary tools to control

- 90 -

invasive termite infestations and thereby help to preserve municipal properties and the assessment value of the housing stock.

1) Management Hire two summer technicians. Training for monitoring and colony level treatments with nematodes, and Trap-Treat-Release.

Approximately 3,000 field traps are installed and mapped. All traps need to be checked on at least a monthly basis, termite activity recorded, and trapped termites extracted and quantified. Trapped termites are treated and released. The numbers of active traps, and number of termites trapped are critical measures for assessing the efficacy of the colony level treatments.

Periodic monthly trap inspection of all managed properties is essential for the accumulation of data by which the termite dispersion pattern is tracked and the termite population size is monitored. The data must be accumulated for a full six month season from May through the end of October. This data is compared year by year and on a block- wide basis.

2) Prevention, Management Spring & Fall Nematode Treatments

A letter is sent to all properties with activity asking them to sign an authorization and release to conduct a nematode treatment. The treatments are scheduled for morning or evening. Nematodes are ordered weekly to ensure freshness. Treatments are conducted daily until all scheduled properties are completed. Treatments are done in with watering can in vicinity of known structural activity, trap activity, or termite habitat. This must be done during periods of milder temperatures, thus spring and fall. The spring treatment will be done in May through mid June and the fall treatment from September through mid October.

of the termite population by a entomopathic nematodes provides periodic population suppression. We are still in the early stages of measuring the efficacy of this action on field populations.

3) Prevention, Management Boron Rod Installation in Fence Posts

Under the municipal termite bylaw all wood posts or other wood in soil contact are required to be removed or made termite resistant. Residents in known active properties are contacted to inform them that their fence posts or wood retaining walls need to be treated to resist termites. A time for this is scheduled. Licensed applicators use a heavy duty electric drill to drill 3/8" holes into the base of each post. The boron rod is inserted and plugged by hammering in a wood dowel. The number of rods installed per property is recorded. Approximately 1,000 additional rods will be installed during 2009.

Boron rods are a low toxicity method of wood preservation and insect deterence for exterior wood in soil contact. Fence posts and wood retaining walls provide one of the main food and nesting resources for termites in the suburban environment. The boron diffuses from the rods into the wood at ground level. Termites consuming boron-treated wood die, thus preventing treated wood from being colonized by termites.

4) Management Obtain research permit for Zinc Borate (ZB) or Disodium Octoborate Tetrahydrate (DOT ) and conduct Trap-Treat-Release (TTR) treatments using trapped termites.

Lab studies have shown that ZB or DOT can serve as an adequate substitute for sulfluramid as the active in TTR for termite control. This method entails the use of very minute quantities of active (e.g. 1 mg/100,000 termites) which is applied directly to the cuticle of trapped termites in combination with resin so as to produce a dry crust on the treated termite that untreated termites will groom off and ingest. Thus the trapped termites are used as vectors to deliver the active to the rest of the colony.

This will be the first field season using ZB or DOT as a substitute for sulfluramid. We will be able to

compare the efficacy of TTR with a borate versus TTR with sulfluramid.

5) Prevention, Detection, Management Digital photo documentation of all phases of control program including and photo- and video-microscopy

The various steps of the control program need to be photo documented for educational purposes. These steps include construction of traps, installation of traps, inspection of traps, extraction of termites, treatment of termites, release of treated termites, application of entompathogenic nematodes, yard wood inspections, yard wood clean up and disposal. In addition, it would be very desirable to record the microscopic details of termite social interactions and nematode infection. The project has two microscopes, including a dissecting and compound microscope. However the compound scope is an older version with poor optics and neither is properly set up for digital or video microscopy. The project has no funding for the equipment purchase upgrades that are desired so that the graphic details of entomopathogenic nematode infection can be recorded and graphically communicated. Thus a compound microscope upgrade with digital camera and video attachments is requested for the program. This will also allow for recording other aspects of termite biology and ecology, grooming behaviour, food exchange and transmission of intestinal protozoa, which help to demonstrate the behaviours which allow Trap-Treat-Release to be effective.

The photo and video documentation of the Area wide Termite Management protocols and relevant details of termite biology, behaviour, ecology and reproduction will be used to develop a highly visual Powerpoint Presentation which shows step by step the procedures involved at the macro-scale and the behavioural and ecological processes at the micro-scale.

Weekends scheduled in July, and the southern half the Yard Wood Cleanup Weekend will be scheduled sometime during August. Prior to each scheduled weekend each yard will be surveyed for yard wood, including wood chip mulch, edging boards, retaining walls, firewood, scrap lumber, etc. and each resident given a sketch of their yard showing which items should be removed to eliminate termite habitat. Although this can be ordered under the bylaw, greater cooperation is achieved, by requesting voluntary participation. Residents help each other to remove yard wood to designated rental bins during the scheduled weekend. The disposed wood must be land-filled due to the possibility of termites in the material. There are significant costs associated with bin rental and tipping fees.

Because this activity is a community project it greatly raises neighbourhood awareness of the local termite problem. Because it is voluntary it tends to enlist people as community participants and meets very little resistance. A huge amount of voluntary manpower can be harnessed. Cost of re- landscaping is picked up by residents. They each pitch in to reduce their own vulnerability and at the same time reduce termite risk for the neighbourhood.

7) Prevention, Detection, Management Create Powerpoint Presentation: "Guidelines for Area-Wide Management of Subterranean Termites" and post to website.

Using the digital photographs and images captured over the season in the field and lab components of the project, a detailed Powerpoint Presentation will be constructed. This will be approximately 25 to 30 frames in length. Of critical importance will be the microscopic video footage of nematode parasitism and life cycle development in the termites. Microscopic video footage will also show other aspects of termite behaviour and ecology.

This will provide the educational component of the project which cover prevention, detection, and management. It will provide a step-

4.2 Multi-year Project a) Is this project a multi-year project? No

4.3 Environmental Responsibility: The primary purpose of the project is to achieve large scale (block wide termite population reduction or eradication). An important secondary purpose of the program is achieve the primary purpose while also greatly reducing the amount of pesticide that would otherwise need to be used to treat individual properties with soil termiticide. Nematode treatments are a biological alternative to insecticide treatment. Currently there are no federal restrictions on the use of nematodes in Canada (personal communication, Regional Manager PMRA). Impel boron rods have long been available in Canada, for exterior wood treatment. A research permit for use of ZB or DOT as the active in TTR will be obtained from PMRA, no difficult is anticipated since both ZB and DOT are already registered in Canada as a wood preservative in Boroguard, BluWood, TimBor and other products. The project will be submitted for review by the Ontario Ministry of Environment (Mr. Geoff Cutten, Hazardous Contaminants Branch).
