West Virginia mosquito questions

What kinds of mosquitoes live in West Virginia?
West Virginia has floodwater mosquitoes (the dominant summer nuisance biter, which surges after heavy rain), the Asian tiger mosquito (a daytime biter that breeds in yard containers), the house mosquito (the main West Nile carrier), and swamp and cattail-marsh mosquitoes tied to the EEE cycle. Which ones dominate a given town depends on its local breeding habitat.
When does mosquito season start and end in West Virginia?
In West Virginia, mosquito numbers build from about mid-June, peak in mid-to-late summer, and fade with the first cool nights of fall. Biting largely stops once temperatures drop below about 50°F, and a hard freeze ends the season.
Is West Nile or EEE a risk in West Virginia?
Both West Nile virus and Eastern equine encephalitis occur in the region, but human cases are rare. West Nile risk peaks in late-summer heat and tracks the house mosquito in developed areas; EEE rises after mid-July in swampy areas. For confirmed local activity, check the West Virginia health department's arbovirus surveillance.
How do I keep mosquitoes out of my yard in West Virginia?
The single biggest thing you control is standing water: empty anything that holds it, keep gutters clear, and change bird baths weekly. Use EPA-registered repellent at dawn and dusk, and for heavy biting a licensed mosquito-control service can treat breeding sites and resting spots you can't reach.
