Seasonal Pest Patterns: What to Expect When

Different pests become active at different times of year.

Spring brings ants and early mosquitoes

Warming temperatures activate ant colonies and early mosquito breeding, making spring a good time for preventive treatment.

Summer is peak season for most flying and crawling insects

Mosquitoes, flies, and many crawling insects are at their most active during summer months, when both temperature and food availability peak.

Fall drives rodents indoors

As outdoor temperatures drop, mice and rats actively seek indoor shelter, making fall a critical time to seal entry points before infestations start.

Winter reduces most insect activity but not all pest risk

While many insects become dormant in winter, indoor pests like rodents and certain cockroach species remain active indoors where temperatures stay warm.

Termite swarming is regionally and seasonally specific

Termite swarms typically occur in spring in many regions, though timing varies by species and climate — a professional can advise on local patterns.
