The following chart shows prevention, control and treatment measures to use with different pests.
|Mosquitoes||Empty and remove unnecessary containers of water. Screen or cover any cisterns or water tanks.||Drain and fill boggy areas and depressions. Repair damaged septic tanks, introduce top feeding fish into ornamental ponds.||Use a light oil or insecticide on ponds or still water. Spray residual insecticide, eg, diazinon or malathion, on outside breeding sites.|
A fly’s reproduction cycle takes approximately 1 week.
|Get rid of all rubbish and manure. Fit doors and windows with screens.||Use knockdown sprays, eg, Raid®, Mortein®, for immediate control||Spray walls and vegetation, especially near rubbish containers, with diazinon, malathion. For seasonal treatment use pyrethroid sprays, eg, alpha-cypermethrin, deltamethrin, on ceilings and window frames.|
Cockroaches live and breed in moist dark places, eg, under refrigerators, in cupboards and pantries. Outdoors they live in piles of debris or rubbish.
|Clean everything frequently, especially kitchens and dining rooms where food is handled.||Remove potential breeding sites. Treat any infestation promptly.||Spray diazinon, propoxur, dichlorvos, or malathion into places where cockroaches hide. Employ a trained, qualified operator to apply baits. Use aerosol sprays of pyrethrum or dichlorvos to flush the insects from their hiding places in heavy infestations.|
|Fleas, lice, ticks||Cut grass frequently and get rid of weeds. Keep carpets and furnishings clean. Check and treat pets regularly.||Use diazinon, pyrethroids and carbaryl for infested areas inside and outside, infested clothes, blankets, mattresses and other bedding.||Fumigate clothing and bedding or sterilise by dry heat or steam using commercial equipment. Treat bed springs and supports with powder or liquid organophosphate, carbarnate or pyrethroid insecticides.|
|Bed bugs||Inspect beds and bedding regularly||Apply an insecticide to baseboards and mouldings, wall crevices, bedsteads, springs and mattresses. Do not soak mattresses or treat infant bedding or cribs.||Use residual sprays containing pyrethroids, organophosphates or carbamates.|
Rats and mice carry disease, eat and contaminate food and cause structural damage.
|Store food carefully and get rid of all rubbish. Proof all holes and accesses to buildings.||Use traps and anti-coagulant baits because of their low level of toxicity for humans and domestic animals, eg, brodifacoum, bromadialone, diphacinone active baits. Remove sources of food and water.||If required, employ a trained, qualified operator to advise and monitor toxic tracking powders and baits.|
