Physical Barriers to Mosquito Bites

Wear clothing that covers your skin. Long-sleeved shirts, long pants, hats, socks, and shoes should be worn outside. Treat clothing, tents, and other gear with permethrin. Clothes treated with pemethrin can be purchased or you can apply it yourself. Permethrin is not for use directly on skin. Some mosquitoes bite through clothing.
Use mosquito netting treated with permethrin when sleeping. Bed nets should have 156 holes per square inch and be long enough to tuck under the mattress. Pramax is a World Health Organization Pesticide Evaluation Scheme (WHOPES)-approved bed net. Bed nets should not be washed or placed in sunlight, because this will remove or inactivate the permethrin. Mosquitoes can get indoors.
Stay in lodging with air conditioning and screens on the windows and doors whenever possible. Mosquito coils containing metofluthrin or allethrin can be burned outside.
