Keep covered up
Most mosquitoes bite between dusk and dawn. Avoid exposing your skin by wearing long sleeved shirts and trousers. Aedes mosquitoes which transmit dengue and yellow fever are mainly active during the day with their peak biting times shortly after sunrise and just before sunset. To avoid being bitten by these daytime biters avoid outdoor shady conditions and sleep under a mosquito net if you take a siesta.


Use effective insect repellent
If your skin is exposed then it is important to use a safe and effective insect repellent on all areas of exposed skin. 


Use a mosquito net at night
Mosquito nets provide very good protection especially when impregnated with the residual insecticide permethrin. Permethrin is poorly absorbed by the skin and has a low mammalian toxicity. There are a number of different styles of mosquito net and you should choose the one most suitable for where you are.


Sleeping in a room with air-conditioning will discourage mosquitoes. 


Use a plug-in insecticide vaporiser
Use a knockdown spray (any fly spray will do) to clear the room of mosquitoes. Plug-in insecticide vaporisers are very effective for overnight protection as long as the room is relatively free from draughts. The vaporisers consist of a heating pad onto which an insecticide soaked tablet is placed. The insecticide gradually vaporises throughout the night killing any mosquitoes that get into the room.


Spray mosquito breeding grounds
If you are staying for long periods in areas where mosquitoes are a problem, then remember that they breed in stagnant water. Mosquitoes lay eggs in as little as a quarter inch of standing water. A good mosquito bite prevention method is to ensure mosquito breeding areas within 500 yards of your accommodation are regularly sprayed or eliminated.
