Pest control
The following chart shows prevention, control and treatment measures to use with different pests.
Pest | Prevention | Control | Treatment |
---|---|---|---|
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 larvicide or light oil on ponds or still water. Spray a residual synthetic pyrethroid insecticide, eg, bifenthrin, permethrin, on outside breeding sites. |
Flies 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, ceilings and window frames and vegetation, especially near rubbish containers with a synthetic pyrethroid spray, eg, alpha-cypermethrin, deltamethrin, permethrin |
Cockroaches 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. | Use sticky board traps to monitor the extent of the cockroach population. Spray a residual synthetic pyrethroid into places where cockroaches hide. Employ a trained, qualified operator to apply baits. Use aerosol sprays of pyrethrum 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 synthetic pyrethroids for infested areas inside and outside, infested clothes, blankets, mattresses and other bedding. | Wash clothing and bedding or sterilise by dry heat or steam using commercial equipment. Treat bed springs and supports with synthetic pyrethroid insecticide, eg, permethrin, deltamethrin, cypermethrin. |
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, eg, permethrin, deltamethrin, cypermethrin. If required, employ a qualified pest management technician to advise and monitor a bedbug control program. |
Rodents 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, eg, brodifacoum, bromadiolone, difethialone, flocoumafen. Remove sources of food and water. | If required, employ a qualified pest management technician to advise and monitor toxic baits. |
