The Georgia pest calendar, month by month
Metro Atlanta sits in one of the highest termite-pressure zones in the United States, with a humid subtropical climate that keeps the rest of the roster busy too: a long mosquito season, fire ants, big outdoor roaches, and just enough winter to push everything indoors for a few months.
What’s active in GA, when
-
January
The brief Georgia winter concentrates activity indoors — rodents in attics and crawl spaces, German roaches in kitchens.
-
February
Termite swarms can open by late February in Atlanta. The single best month for a pre-season inspection.
-
March
Subterranean termites swarm in earnest on warm days after rain; Argentine ants wake and trail along foundations.
-
April
Peak termite month; mosquito season opens as spring rains fill containers. Fire ant mounds multiply.
-
May
Mosquitoes hit stride in tree-shaded neighborhoods; ticks active at wooded edges; wasps build on eaves.
-
June
Humid heat brings smoky brown roaches — the big Georgia 'palmetto bug' — to foundations and mulch beds.
-
July
Peak mosquito month — afternoon storms restock every breeding site weekly. Spiders follow the insect boom.
-
August
Yellow jackets reach peak colony size — ground nests in lawns are the late-summer hazard.
-
September
Warm falls keep mosquitoes and roaches fully active; fire ants rebuild in milder soil.
-
October
Mosquitoes bite deep into October. First cool nights start rodents probing garages and crawl spaces.
-
November
Rodent exclusion month — roof rats use Atlanta's tree canopy to reach rooflines. Overwintering insects settle in.
-
December
Indoors: rodents, German roaches, crawl-space moisture pests. Termites keep feeding below ground all winter.
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.

Georgia pest season questions, answered straight
How bad is termite pressure in Georgia, really?
Among the highest in the country — Atlanta sits in a very heavy pressure zone and subterranean termites work Georgia's mild soil year-round, swarming late February through May. Buyers and lenders here treat a termite letter as non-negotiable for good reason.
When does mosquito season start and end in Atlanta?
Early April through late October, peaking with the July–August thunderstorm pattern. Atlanta's shade cover and puddle-holding clay give mosquitoes unusual daytime harborage — yard treatment plus standing-water discipline beats either alone.
What is the giant roach I keep seeing in my Atlanta home?
Almost certainly a smoky brown or American cockroach — the 'palmetto bug.' They live outdoors in mulch and trees and wander in through gaps in humid weeks. Unlike German cockroaches, a sighting usually means an entry-point problem — but recurring sightings deserve a professional look.
