Minimize outdoor activities between dusk and dawn when Anopheles mosquitoes commonly bite.

Wear long-sleeved shirts and long trousers.

Apply insect repellent containing approximately 30 percent N, N-diethyl-3-methylbenzamide (DEET) to exposed skin at dusk. Repeated application may be required every three to four hours.

Stay in a building with air-conditioning or with screens over doors and windows. If no screens are available, windows and doors should be closed at sunset.

Apply aerosolized insecticides in living or sleeping areas at dusk.

Use a strong fan to inhibit the flight of mosquitoes.

Use a mosquito bed net, preferably one that is impregnated with permethrin, if accommodation allows entry of mosquitoes. Bed nets can be soaked in this insecticide solution and hung out to dry. They should be retreated every six months to maintain effectiveness.
