Mosquito Control Measures Biolodical Method:-Use of Fish Guppy/ Gambusia / Bti /B- Sphericus etc. Source Reduction:- Elimination of reduction of breeding sites.
Filling up burrow pits,ditches,unused irrigation cannals,wells,deweeding,chanalization etc.
Personal Protection:- Use of Repellant Use of mosquito net. Application of Nylon mesh to doors and
windows.
Formula for measurement of surface area of Bed net
Surface Area =2 ( a + b ) +c where a=length x height b=height x width c=length x Width
Methods of Impregnation
Prepare solution in optimum quality of water with required quantity of insecticides.
Soak bed net in solution thoroughly. Do not hang it, dry it by spreading on a
rubber sheet in a shed. Residual Efficacy:-6 months if not washed Precautions:-Avoid contamination of
skin,eyes,mouth with insecticide formulation.
If contaminated ,wash with soap and water.
Impregnation of Bed nets Quality of Bed nets
Bednet hole size:- Not bigger than 1.2 to 1.5 mm.
diameter .i.e.6 to 8 holes to 10mm linear length.
Dosage:- 25 mg Deltamethrin/sq.mt. or 50mg Cyfluthrin/sq.mt.
