The species of mosquitoes that can transmit West Nile Virus (WNV) in Ada County are active from dusk to dawn. If you spend any time outdoors in the evening, Ada County Mosquito Abatement District (ACMAD) encourages you to wear long-sleeved light-colored clothing and an EPA-approved mosquito repellant (with an active ingredient of DEET, Picardin, or Oil of Lemon Eucalyptus). You can also help to protect you and your family from WNV by looking for any sources of standing water on your property. Mosquitoes can breed in an amount of water as small as a bottle cap, be sure to look for any clogged drains, tires, toys, etc. that could gather water. Also, be careful to not overwater your lawn or garden, as these are prime examples of habitat for the WNV vector species in Ada County.
