DressWear shoes, socks, long pants, and a long sleeved shirt when outdoors for long periods of time or when mosquitoes are most active. Clothing should be light colored and made of tightly woven materials to keep mosquitoes away from the skin.

DeetFor additional protection from mosquitoes, use an insect repellent containing DEET (N, N-diethyl_m-toluamide) or Picaridin (KBR 3023). Other insect repellents such as oil of lemon eucalyptus and IR3535 are also registered by the EPA but may be less effective than products containing DEET. It is important to follow the product guidelines when using insect repellent.
