As temperatures shift throughout the year, so does pest activity. From insect pests that thrive in warm weather to common winter pests that seek shelter indoors, each season brings its own pest problems. Being aware of what to expect allows you to take smart preventive measures and keep your home pest-free all year long.
Below, we break down what pests are most active during each season, along with practical steps you can take to prevent future infestations and safeguard your home.
Spring: Wake-Up Call for Pests
As temperatures rise in early spring, many pests emerge from winter hiding and begin breeding. Excess moisture from melting snow and rain can create moisture issues in crawl spaces, damp areas, and around your home’s foundation, drawing in pests.
Common spring pests:
- Ants, including carpenter ants
- Spiders, including brown recluse
- Cockroaches
- Termites
- Mosquitoes
Spring pest tips:
- Eliminate standing water in the yard
- Seal cracks and potential entry points
- Trim tree limbs and remove brush piles near the home’s perimeter
- Address moisture issues in crawl spaces and utility lines
Summer: Peak Pest Activity
As the season progresses, warm weather and abundant food sources fuel breeding for many insects and rodents. Outdoor areas become prime territory for pests, and your home is a tempting retreat from the heat.
Common summer pests:
- Mosquitoes
- Ticks
- Flies
- Bed bugs
- Stink bugs
- Bees and wasps
Summer pest tips:
- Seal entry points like window moldings, small cracks, and light fixtures
- Store firewood away from the house
- Use airtight containers for pantry items to eliminate food sources
- Keep pets clean to avoid flea or tick problems
Fall: Pests Seek Shelter
As temperatures drop in early fall and late fall, pests start looking for protected areas to ride out the colder months. This is when many persistent pests try to enter your home.
Common fall pests:
- Spiders
- Rodents like mice, rats, and Norway rats
- Cockroaches
- Brown recluse spiders
Fall pest tips:
- Inspect for gnaw marks, droppings, or nesting materials
- Check for easy access points around doors, vents, and crawl spaces
- Clean out clutter from secluded areas like garages, basements, and attics
- Seal cracks along your home’s perimeter
Winter: Pests Go Into Hiding—In Your Home
Don’t let the cold weather fool you; winter pests are still active, just less visible. Some pests remain active year-round, while others settle into hiding spots inside your walls, attic, or behind appliances.
Common winter pests:
- Rodents
- Cockroaches
- Spiders
- Bed bugs
- Other pests like carpenter ants or silverfish
Winter pest tips:
- Insulate exposed pipes and fix leaks in sink areas
- Block small openings around window moldings and utility lines
- Regularly vacuum and wash bedding to control bed bugs
- Watch for signs of rodent activity—these can lead to diseases like rat bite fever
