Spring is termite swarmers after rain, and ants waking up. Summer is mosquitoes and wasps. Fall is mice at the door. Winter is indoor rodents and kitchen Germans.

September · this month
Mice moving in, yellowjackets hungrier, last mosquito flights.
Door sweeps and the garage gap matter more than another yard spray.
How to use this month
Log what you actually saw: a dropping, a winged insect, a nest, a standing-water saucer. Then open the matching guide. The sighting log holds the date and the room before you wipe the evidence.
Gulf and Deep South yards stay busy in winter. Visit spacing for that climate is on monthly vs quarterly pest control.
Where the timing comes from
NC State Extension puts subterranean termite swarmers in spring, often after rain. Save one insect. Vacuuming the pile removes the only evidence. Daylight vs Gulf Formosan dusk is on when do termites swarm.
UGA Extension treats fall and winter as the window when mice and rats move into warm houses. Door sweeps beat another yard spray.
CDC covers mosquito bites around the home. Dump standing water before you shop a fogger. Yard spray vs a season route is on mosquito treatment cost.
