The Florida pest calendar, month by month
Tampa doesn't get a pest off-season — it gets a wet season and a dry season. Year-round warmth means mosquitoes in every month, some of the country's heaviest termite pressure (subterranean and drywood both), tropical ants that never stop, and roof rats that treat attic and citrus tree as one habitat.
What’s active in FL, when
-
January
The dry season's coolest month is still active: roof rats peak in attics and citrus, and indoor ants keep trailing.
-
February
Subterranean termite swarm season begins in the Tampa Bay area — earlier than almost anywhere in the country. Inspection time.
-
March
Peak subterranean swarm weeks — warm evenings after rain fill the air near infested structures. Mosquitoes build ahead of the wet season.
-
April
Ant pressure climbs across the board — Argentine, big-headed, and ghost ants all trail hard. Drywood termite swarms begin as evenings warm.
-
May
The wet season looms: mosquito populations jump with the first heavy rains, and palmetto bugs (American and smoky brown roaches) get busy at foundations.
-
June
Daily thunderstorms open peak mosquito season — breeding sites refill every afternoon. Drywood termite swarmers fly on humid evenings.
-
July
Peak everything, Florida edition: mosquitoes at maximum, roaches thriving in the humidity, ants splitting colonies indoors to escape saturated soil.
-
August
The soak continues — mosquito pressure holds at peak, and heavy rain pushes big roaches and ants indoors in waves.
-
September
Still peak wet season. Yard drainage and container discipline matter most right now; wasp colonies reach full size.
-
October
The rains taper but mosquitoes barely notice. Roof rats begin their dry-season move into attics — Tampa's version of 'rodent season.'
-
November
Dry season opens: cooler nights concentrate rodent activity in structures, while ants and roaches stay active in the mild warmth.
-
December
Florida's mildest month still runs a full roster — roof rats in attics, ants trailing indoors, and mosquitoes on warm evenings. There is no true off-season here.
Calendars describe typical years — weather moves the edges. An early warm spring opens termite and mosquito season sooner; a mild fall stretches it. When in doubt, what you’re seeing at your own home outranks any calendar.

Florida pest season questions, answered straight
Is there a mosquito season in Tampa, or is it year-round?
Effectively year-round, with a pronounced peak: the June–September wet season, when daily storms refill every breeding site. Year-round service with wet-season intensity matches the biology here.
What's the difference between subterranean and drywood termites in Florida?
Subterranean termites live in soil and enter from below, swarming roughly February–April in Tampa; drywood termites live entirely inside the wood and swarm on humid late-spring and summer evenings. Florida homes face both, and treatments differ — identification comes before any quote.
Why do I have rats in my attic in Florida?
Roof rats — Tampa's dominant rat — climb power lines, fences, and tree canopy to enter at the roofline, and they favor attics. Activity spikes in the cooler dry season; citrus trees are a famous attractant. Control is roofline exclusion plus trapping — poison alone creates worse problems.
