On this page
Mosquitoes
Prevention
Empty and remove unnecessary containers of water. Screen or cover any cisterns or water tanks.
Control
Drain and fill boggy areas and depressions. Repair damaged septic tanks, introduce top feeding fish into ornamental ponds.
Treatment
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 one week.
Prevention
Get rid of all rubbish and manure. Fit doors and windows with screens.
Control
Use knockdown sprays, for example, Raid®, Mortein®, for immediate control
Treatment
Spray walls, ceilings and window frames and vegetation, especially near rubbish containers with a synthetic pyrethroid spray, for example, alpha-cypermethrin, deltamethrin, permethrin
Cockroaches
Cockroaches live and breed in moist dark places, for example, under refrigerators, in cupboards and pantries. Outdoors they live in piles of debris or rubbish.
Prevention
Clean everything frequently, especially kitchens and dining rooms where food is handled.
Control
Remove potential breeding sites. Treat any infestation promptly.
Treatment
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 and ticks
Prevention
Cut grass frequently and get rid of weeds. Keep carpets and furnishings clean. Check and treat pets regularly.
Control
Use synthetic pyrethroids for infested areas inside and outside, infested clothes, blankets, mattresses and other bedding.
Treatment
Wash clothing and bedding or sterilise by dry heat or steam using commercial equipment. Treat bed springs and supports with synthetic pyrethroid insecticide, for example, permethrin, deltamethrin, cypermethrin.
Bed bugs
Prevention
Inspect beds and bedding regularly.
Control
Apply an insecticide to baseboards and mouldings, wall crevices, bedsteads, springs and mattresses. Do not soak mattresses or treat infant bedding or cribs.
Treatment
Use residual sprays containing pyrethroids, for example, 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.
Prevention
Store food carefully and get rid of all rubbish. Proof all holes and accesses to buildings.
Control
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.
Treatment
If required, employ a qualified pest management technician to advise and monitor toxic baits.
