Buffalo and the surrounding Western New York region experience a distinct mosquito season shaped by cold winters, heavy snowfall, spring snowmelt, and warm, humid summers. While mosquito activity is dormant during winter, populations can rise quickly once temperatures increase and moisture becomes widespread in late spring and early summer.
Mosquitoes in the Buffalo area are commonly found near standing water, wetlands, wooded areas, and residential neighborhoods with poor drainage, especially after periods of rain.

Several environmental factors support mosquito populations in Western New York:
Spring snowmelt that creates widespread standing water

Wetlands, creeks, and drainage corridors throughout the region
Humid summer conditions that extend adult mosquito survival
Dense residential neighborhoods with container breeding opportunities
These conditions allow multiple mosquito species to emerge and persist throughout the season.
