Termite Control Tactics
• Possible Strategies– Physical– Cultural– Biological– Chemical
• Wood Treatments• Soil Barriers• Baits
![Page 3: Kansas IPM Education October 2005 Termite Treatments Termite Treatments Dr. Richard Houseman Assistant Professor of Entomology Division of Plant Sciences](https://reader030.vdocuments.us/reader030/viewer/2022032517/56649cb75503460f9497ce57/html5/thumbnails/3.jpg)
Kansas IPM EducationOctober 2005
Cultural Controls
• Avoid wood-to-soil contact– Log piles against structures– Construction debris– Backfill/front stoop shouldn’t contain wood
• Moisture management– Drainage away from foundation– Gutters, downspouts well-maintained

Physical Control
• Barriers to tunneling– Sand, basalt, granite, glass, etc.
– Grain size of 2.0-2.8 mm.
– 20cm thick.
– Stainless Steel Mesh• Termi-Mesh
– Thick rubber mats
• Pre-construction only
![Page 5: Kansas IPM Education October 2005 Termite Treatments Termite Treatments Dr. Richard Houseman Assistant Professor of Entomology Division of Plant Sciences](https://reader030.vdocuments.us/reader030/viewer/2022032517/56649cb75503460f9497ce57/html5/thumbnails/5.jpg)
Kansas IPM EducationOctober 2005
Biological Controls
• Nematodes (Steinernema)
– Not effective against subterranean termites in field trials
• Fungi (Metarhizium)
– More successful than nematodes– Bio-Blast (Paragon Professional) – applied as a dust/WP
• Bacteria (Bacillus)– Has been studied, but not currently used

Chemical Controls
• Wood Treatments– Reduce feeding on structural wood– Pressure treatments or spray-on
• Products– BoraCare/Jecta (Nisus) www.nisuscorp.com
• disodium octaborate tetrahydrate
– Tim-bor (U.S. Borax) www.borax.com• disodium octaborate tetrahydrate

Kansas IPM EducationOctober 2005
Chemical Controls
• Chemical Barriers– Applied to soil around structures– 4gal./10ft./1ft.depth– Restricted-use chemicals only
• Repellent vs. Non-repellent?
![Page 8: Kansas IPM Education October 2005 Termite Treatments Termite Treatments Dr. Richard Houseman Assistant Professor of Entomology Division of Plant Sciences](https://reader030.vdocuments.us/reader030/viewer/2022032517/56649cb75503460f9497ce57/html5/thumbnails/8.jpg)
Kansas IPM EducationOctober 2005
Why Soil Barriers?
• To protect areas of the structure where termites are likely to enter.

Subterranean Termite Control
• Repellent vs. Non-repellents?– Repellent (Pyrethroids)
• Termites detect and move away from treated soil• No mortality
– Non-repellent (Various)• Termites don’t detect treated soil and enter • Mortality results

Chemical Controls
• Managing Reticulitermes Using Baits – Just ‘killing the queen’ doesn’t work– Centers of activity change in habitat– Splitting colonies can occur using soil
termiticides– Termite baits seek to address colony
networks

Why Baiting?
• To reduce the number of subterranean termites in the vicinity of a structure.
![Page 33: Kansas IPM Education October 2005 Termite Treatments Termite Treatments Dr. Richard Houseman Assistant Professor of Entomology Division of Plant Sciences](https://reader030.vdocuments.us/reader030/viewer/2022032517/56649cb75503460f9497ce57/html5/thumbnails/33.jpg)

Baiting Methods
Four basic methods have been examined:1. Monitoring stations followed by consumable
bait when termites are located
2. Consumable bait in stations prior to detection
3. Consumable bait at the site of infestation
4. Trapping followed by groomable coating applications and release back into station

Typical Baiting Sequence

Baiting Strategies
• Areas where foraging is likely– Temperature and moisture consistent– Food sources nearby– Active sites are best
• Do not want to disrupt foraging/feeding
• Distance between stations– Clustered stations
![Page 36: Kansas IPM Education October 2005 Termite Treatments Termite Treatments Dr. Richard Houseman Assistant Professor of Entomology Division of Plant Sciences](https://reader030.vdocuments.us/reader030/viewer/2022032517/56649cb75503460f9497ce57/html5/thumbnails/36.jpg)
Kansas IPM EducationOctober 2005
Baiting Systems
• Design considerations– Disturbance at station– Monitor integrity/acceptance– Type of active ingredient
• Palatability of active ingredient• Metabolism of active ingredient
– Bait matrix
