The best way to prevent West Nile disease or any other mosquito-borne illnesses is to reduce the number of mosquitoes around your home and to take personal precautions to avoid mosquito bites.
• Avoid being outdoors when mosquitoes are most active, especially between dusk and dawn.
• When outdoors, wear shoes, socks, long pants and a long-sleeved shirt, and apply insect repellent that contains DEET, picaridin, oil of lemon eucalyptus or IR 3535, according to label instructions. Consult a physician before using repellents on infants.
• Make sure doors and windows have tight-fitting screens. Repair or replace screens that have tears or other openings. Try to keep doors and windows shut, especially at night.
• Eliminate all sources of standing water where mosquitoes can breed, including water in bird baths, ponds, flower pots, wading pools, old tires or any other containers or receptacles in which mosquitoes might breed.
