1. Mice and Rats
When the weather turns cold, rodents head indoors faster than you can say cheese. Mice can squeeze through holes the size of a dime, and rats can gnaw through wood, plastic, and even lead pipes. Once inside, they multiply quickly, contaminate food, and chew electrical wiring — creating potential fire hazards.
Common signs: Droppings along baseboards, scratching noises at night, and shredded nesting materials in attics or garages.
Prevention tips:
- Keep firewood and debris piles away from the home.
- Seal gaps and cracks around your foundation and siding.
- Store pet food and pantry items in sealed containers.
2. Spiders
While many outdoor spiders slow down in winter, indoor species like the house spider or cellar spider thrive in warm, dry environments — basements, corners, or storage spaces. Most are harmless, but finding webs in every corner isn’t exactly cozy winter décor.
Prevention tips:
- Seal cracks around windows and doors to block entry.
- Vacuum webs and corners regularly.
- Reduce clutter in basements or garages.
3. Raccoons and Squirrels
When the attic feels warmer than a tree hollow, raccoons and squirrels see an open invitation. These wildlife pests can cause serious damage — tearing insulation, chewing wiring, and contaminating spaces with droppings.
In winter, mother squirrels may even nest indoors to raise their young, making humane removal crucial.
Warning signs: Heavy movement sounds in the attic, torn soffit vents, or insulation pulled apart.
Prevention tips:
- Don’t leave pet food outside overnight.
- Trim branches that touch your roofline.
- Check attic vents and chimneys for gaps or missing covers.
4. Cockroaches
It’s true — cockroaches don’t just survive the cold, they thrive indoors during winter. These pests love warm, moist areas like kitchens, bathrooms, and laundry rooms. Once they find water and crumbs, they’ll stick around, bringing bacteria and allergens with them.
Prevention tips:
- Wipe counters and sweep floors regularly.
- Fix leaky faucets or pipes.
- Empty trash cans often and keep them sealed.
5. Silverfish and Other Moisture Pests
You might not see them often, but silverfish and other small moisture-loving pests sneak indoors during winter to find humidity and warmth. They hide in bathrooms, attics, and storage boxes — and love munching on paper, books, and fabric.
Prevention tips:
- Inspect cardboard boxes before bringing them inside.
- Run a dehumidifier in damp areas.
- Store important items in airtight containers.
