Living on the Space Coast means enjoying beautiful weather, beaches, and outdoor activities — but it also means dealing with mosquitoes for much of the year. Understanding Brevard County's mosquito season helps you plan ahead and protect your family from bites and mosquito-borne diseases.
Brevard County Mosquito Season Timeline
Unlike northern states where mosquito season is limited to summer, Brevard County's subtropical climate means mosquitoes can be active for 8-10 months of the year:
- March-April: Early season — mosquito populations begin growing as temperatures consistently hit 70°F+. First generation larvae hatch in standing water from spring rains.
- May-June: Populations ramp up significantly as the rainy season begins. This is the ideal time to start professional mosquito treatments.
- July-September: Peak season — daily afternoon thunderstorms create abundant breeding sites. Mosquito activity is highest at dawn and dusk but many species bite throughout the day.
- October-November: Activity decreases but remains significant. Many species stay active until nighttime temperatures drop below 60°F consistently.
- December-February: Reduced activity, but mild winters mean some mosquitoes remain active, especially near the coast and in protected areas.
Why Brevard County Is a Mosquito Hotspot
Several factors make our area particularly prone to mosquitoes: proximity to the Indian River Lagoon and other waterways, abundant marshland and wetlands, 50+ inches of annual rainfall, warm temperatures year-round, and dense vegetation that provides harborage. The Brevard County Mosquito Control District has identified over 40 species of mosquitoes in our area.
7 Ways to Reduce Mosquitoes Around Your Home
Dump standing water weekly — flower pot saucers, bird baths, kiddie pools, and clogged gutters are top breeding sites
Keep your lawn mowed and bushes trimmed — mosquitoes rest in tall grass and dense vegetation during the heat of the day
Repair or replace damaged window and door screens
Use outdoor fans on patios and porches — mosquitoes are weak fliers and can't navigate wind above 10 mph
Treat ornamental ponds and rain barrels with mosquito dunks (BTI) — a biological larvicide safe for fish and wildlife
Clear debris from gutters and ensure proper drainage around your property
Schedule professional perimeter treatments monthly during peak season for the most effective protection
