Mosquito Season in North Carolina Ends After First Frost
Mosquito activity in North Carolina is currently moderate to high, with the biting season typically running from May through October. The state experiences approximately 50 to 100 confirmed cases of West Nile Virus (WNV) annually, with risk areas including coastal swamps, Piedmont metros, and the Smoky Mountain foothills. Aedes albopictus is the primary mosquito species, active during the day in cities like Charlotte, Raleigh, Greensboro, and Durham. Aedes aegypti is occasionally found in southeastern coastal counties, while Culex species dominate in other regions. The first hard freeze, which usually occurs around October 28, marks the end of mosquito season in the state. This information is based on CDC ArboNET surveillance and regional risk models (source: mywild.report).
