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.

- Plan for spring: Schedule termite inspection before swarm season.
