DRAIN: Standing Water. Help reduce the number of mosquitoes around your home by emptying standing water from flowerpots, gutters, buckets, pool covers, pet water dishes, discarded tires, and birdbaths on a regular basis.
MOSQUITO-PROOF: Mosquito-Proof Your Home. Install or repair screens on windows and doors to keep mosquitoes outside.
*APPLY: Apply Insect Repellent when outdoors. The Centers for Disease Control recommends the use of insect repellent products containing active ingredients which have been registered with the U.S. Environmental Protection Agency (EPA) for use as repellents applied to skin and clothing.
*WEAR: When weather permits, wear long sleeves, long pants, and socks when outdoors. Mosquitoes may bite through thin clothing, so spraying clothes with repellent containing permethrin or another EPA-registered repellent will give extra protection.
* Take extra care to use insect repellent and wear protective clothing from dusk to dawn or consider avoiding outdoor activities during these times. The mosquitoes (Culex) that are most likely to transmit WNV are most active from dusk to dawn.
