The Long Island Seasonal Pest Calendar

Long Island's pest profile shifts dramatically with the seasons. This calendar helps you stay ahead of which pests show up when — and what to do about each.

Spring (March–May)

• Termite swarms: Peak activity. Watch for winged swarmers near windows. Schedule a termite inspection.
• Carpenter ants: Become active as temperatures rise.
• Mosquitoes: First treatments should begin in April for season-long control.
• Tick season starts: Nymphal blacklegged ticks emerge — peak Lyme transmission window.

Summer (June–August)

• Mosquitoes peak: Maintain 21-day spray intervals.
• Wasps and hornets: Nest growth peaks; same-day removal recommended.
• Spiders: Increased indoor activity in basements and garages.
• Fleas: Peak activity on pets and in yards.
• Bed bugs: Travel season drives infestation spikes.

Fall (September–November)

• Rodents move indoors: Schedule rodent-proofing early in the season.
• Wildlife: Squirrels, raccoons seeking attic dens.
• Stink bugs and box elder bugs: Aggregate on warm exterior walls.
• Yellow jackets peak: Late-summer aggression at outdoor dining.

Winter (December–February)

• Rodent activity continues indoors: Active calls remain high.
• Cockroaches: Steady indoor activity in heated spaces.
• Termites: Subterranean activity continues underground year-round.
• Plan for spring: Schedule termite inspection before swarm season.
