The Yearly Pest Calendar Every Homeowner Should Know

Pests are active year-round, but different species peak during certain seasons. Knowing what to expect throughout the year allows homeowners to prepare and respond effectively. Seasonal patterns in pest behavior can help reduce infestations before they become major problems.

Spring: Ants and Termites

As temperatures rise, ants begin foraging indoors in search of food. Termites also become active during spring swarms, often unnoticed until damage has already begun. Keeping kitchens clean and inspecting wooden structures for weakness are important preventative steps. Moisture control is also critical, as both ants and termites are drawn to damp environments.

Summer: Mosquitoes, Flies, and Wasps

Warm weather supports rapid insect breeding. Mosquito populations grow quickly in standing water, while houseflies invade through open doors and windows. Wasps are particularly aggressive during this season as they defend nests. Using screens, eliminating water sources, and sealing entry points can reduce household exposure. Outdoor dining areas should be cleared of food debris to minimize attraction.

Fall: Rodents and Spiders

As outdoor temperatures drop, rodents seek shelter indoors. They can squeeze through very small openings, so sealing cracks and gaps around the home is essential. Spiders also become more visible in autumn as they search for mates, though many are harmless. Traps and exclusion techniques are effective ways to manage both concerns.

Winter: Cockroaches and Mice

Cold weather drives pests deeper into homes where warmth and food are available. Cockroaches often settle in kitchens and bathrooms, while mice nest in walls and storage areas. Regular cleaning and careful food storage help reduce risk. Professional support from pest control companies can also provide lasting protection during the colder months.

A yearly awareness of pest activity ensures homeowners stay prepared, keeping their living spaces healthier and safer throughout every season. To learn more, feel free to check out the accompanying infographic below.
