A month-by-month guide to pest activity across Brooklyn, Queens, Manhattan, and Nassau County — so you're never caught off guard by what each season brings.
# Seasonal Pest Calendar for Brooklyn, Queens, and Nassau County
Pest activity across our service area follows predictable seasonal patterns. Understanding what each season brings — from German cockroach surges in summer apartments to fall rodent entry into Brooklyn brownstones — lets you act proactively rather than reactively. This calendar is based on years of providing pest control near me across Brooklyn, Queens, Manhattan, Nassau, and Suffolk Counties.
January – February: Indoor Rodents and Cockroaches
Peak season for indoor rodent activity. Mice settled in wall voids are breeding — a female mouse can produce a litter every 3 weeks. German cockroaches in buildings continue reproducing year-round in warm interiors. Watch for: Scratching in walls, droppings in cabinets, cockroach activity in kitchen and bathrooms. Action: Rodent trap monitoring; professional cockroach treatment if activity is observed.
March: Termite Swarmers Begin
Late March brings the first warm days triggering termite swarmer activity in Brooklyn brownstones, Queens row houses, and Nassau County homes. Carpenter ants also become active. Watch for: Winged insects near windows or foundation; shed wings near entry points. Action: Termite inspection if swarmers observed.
April: Ant Season / Stinging Insect Queens
Odorous house ants and pavement ants begin trailing indoors. Yellow jacket and paper wasp queens start new nests. Watch for: Ant trails in kitchen; small wasp nests forming under eaves. Action: Ant treatment before colonies reach full size; early wasp nest removal.
May: Peak Termite Swarmers / Tick Season Begins
Peak swarmer activity and the start of tick nymph season. Watch for: Termite swarmers; ticks on pets or people after outdoor activity in green spaces. Action: Termite inspection if swarmers observed; yard tick treatment for Nassau County properties.
June – August: Peak Pest Season
Cockroach colonies at maximum size in NYC apartment buildings. Mosquitoes at peak. Yellow jacket colonies growing rapidly through July; at maximum aggression in August. Watch for: Cockroach sightings; mosquito pressure in backyards; established wasp nests. Action: Monthly mosquito treatment; wasp nest removal — never treat mature yellow jacket nests yourself; call Jet Pest Control.
September: Fall Invasion Begins
Stink bugs aggregate on exterior walls in Queens and Nassau County. The critical time to seal entry points before overwintering insects and rodents find their way in. Watch for: Stink bugs on south-facing walls; beginning of rodent entry attempts. Action: Fall perimeter treatment in early September; begin rodent exclusion work.
October: Peak Rodent Entry Month
October is the primary month mice enter homes. Without exclusion, this is when winter infestations begin. Watch for: Scratching sounds at night; fresh droppings in previously clean areas. Action: Exclusion service; trap placement; exterior fall treatment.
November – December: Monitoring Season
Pest activity decreases outdoors but continues indoors. Watch for: Overwintering insects emerging on warm days; continued rodent signs; pantry pest activity in stored dry goods. Action: Rodent trap checks; pantry review.
