Pest problems don’t happen only in summer—each season brings its own set of unwanted guests. Understanding which pests are most active during different times of the year can help you take preventative measures before an infestation begins.
In this post, we’ll break down the most common pests by season and share expert tips on how to keep them out of your home.
Spring: The Season of Awakening Pests
Common Spring Pests:

✅ Wasps & Bees – Building nests near homes.
How to Prevent Spring Pests:
✔ Seal cracks and entry points before pests become active.
✔ Eliminate standing water to prevent mosquito breeding.
✔ Keep food sealed to avoid attracting ants.

Summer: Peak Pest Season
Warm weather means pests are at their most active, breeding rapidly and invading homes in search of food and water.
Common Summer Pests:
✅ Mosquitoes – Thrive in warm, humid conditions.

Fall: The Season of Nesting Pests
As temperatures drop, pests start looking for warm places to shelter before winter. This is when rodents and insects seek entry into homes, making fall a critical time for prevention.
Common Fall Pests:
✅ Rodents (Mice & Rats) – Seeking warmth indoors.

✔ Vacuum regularly to remove stink bugs before they settle in.
Winter: The Time for Hidden Pests
While many pests slow down in winter, some continue living indoors, causing infestations. This is when rodents, bed bugs, and cockroaches become the biggest threats.
Common Winter Pests:
✅ Rodents (Rats & Mice) – Nesting inside homes and chewing on wires.
✅ Bed Bugs – Thrive in heated homes and travel easily through luggage.
✅ Cockroaches – Surviving indoors near food and moisture.
✅ Silverfish – Hiding in bathrooms and basements.
How to Prevent Winter Pests:
