Florida Mosquito Season: Month-by-Month Activity Calendar
Unlike northern states, Florida's mosquito season never fully ends. The calendar looks different depending on whether you're in South Florida, Central Florida, or North Florida, here's what to expect each month.
Why Florida's Mosquito Season Is Different
Most of the US has a defined mosquito season tied to the first killing frost. Florida rarely gets hard freezes south of the panhandle, and South Florida's subtropical climate means many mosquito species are active year-round. The main variable is intensity, not presence.
