$50 OFF your first service + FREE inspectionNew customers · No code needed · No expirationIf you're swatting mosquitoes in November in Florida and wondering when the season ends, here's the honest answer: down here, it doesn't really. South Florida never gets cold enough for long enough to shut mosquitoes down. November still has warm evenings, water left over from the rainy season and the last tropical systems, and plenty of small containers around the house where mosquitoes can breed. There are fewer than in August. But the ones that are left still bite, and they're living closer to your back door than you'd think.
Why are there still mosquitoes in winter in Florida?
Mosquitoes slow down when it gets cold. They need warmth to develop, and a real freeze kills off the adults and stalls the eggs and larvae. Central and North Florida get some of that. We mostly don't. A cold front might drop us into the 50s for a morning or two, and then it's back to 80 degrees and humid by the afternoon.
As long as it stays warm, the cycle keeps turning: egg to larva to adult in about a week or so when it's hot, a little slower when it's cooler, but it doesn't stop. That's why mosquitoes in winter in South Florida feel less like an off-season and more like a slower version of summer.
The water didn't all go away
The rainy season usually winds down sometime in October, but it leaves a lot behind. Low spots in the yard stay soggy. Gutters packed with leaves hold water for weeks. Then a late tropical storm or a stalled front comes through and refills everything.
The mosquitoes that bother people most around the house aren't breeding in the lake down the street. They're in a bottle cap's worth of water: the saucer under a potted plant, a kid's toy in the grass, the tarp over the grill, a clogged downspout, a corrugated drain pipe, a bromeliad. Our mosquito breeding sites guide walks through the full list, and it's worth a lap around the yard with it in hand.
Why mosquitoes in November in Florida seem worse
The container mosquitoes around South Florida homes, including the yellow fever mosquito, have a few habits that make fall feel worse than it should:
- They bite during the day. Not just at dusk. If you're getting bitten at lunch on the patio, it's probably one of these.
- They stay close. They don't travel far from where they hatched, so if they're biting you, they likely came from your yard or your neighbor's.
- Their eggs can wait. Females lay eggs just above the waterline inside a container. The eggs can sit dry for months and hatch as soon as rain fills the container again. A dry December doesn't clear them out. It just pauses them.
- They hide in the shade. Between bites they rest in dense shrubs, under decks and along shaded walls, out of the sun and the wind.
If you've read our rainy-season guide, the "drier months" section explains how this carries into winter and spring.
What a monthly visit does in the fall
People often cancel mosquito service when the rain stops. Down here, fall is when staying on schedule pays off, because you're working against a smaller population that can bounce back with the next storm. For how long each visit holds up in this weather, see how long a mosquito treatment lasts.
On a monthly visit, a technician:
- Treats resting spots with a backpack fogger, using a professional mosquito barrier spray treatment on the shady places mosquitoes wait out the day: dense shrubs, under the deck, along shaded walls and under eaves.
- Applies larvicide to breeding spots around the home, like containers that can't be emptied, gutters and drains. We never treat ponds, lakes or canals.
- Points out new water that's collecting since the last visit, so you can tip it or fix it.
Only monthly mosquito plans include larval traps. They use a growth regulator, like birth control for insects, to cut down on the larvae that make it to adulthood.
Keep kids and pets off treated areas until dry, and follow your technician's instructions. Our treatment process page explains what to expect on each visit, and the mosquito FAQ covers how often to treat.
Hosting something outside?
November and December fill up with backyard dinners, birthday parties and Thanksgiving at the long table on the patio. If you don't want monthly service, a one-time event spray before a gathering can help cut down the mosquitoes before your guests arrive. Book it ahead of time so the treated areas are dry by the time people come out.
