How to Keep Mice, Spiders, and Other Pests Out of Your Home This Winter

The holiday season brings warmth, joy, and time with family—but it also invites unwanted pests like mice, spiders, and cockroaches into our homes. As temperatures drop, these critters seek shelter, food, and water, making your home an ideal target. Without proper precautions, you might find uninvited guests lurking in your pantry, attic, and even Christmas tree. Here’s how you can prevent a winter pest infestation and keep your home pest-free this holiday season.

1. Why Do Pests Invade Homes in Winter?

Winter weather drives pests indoors for three main reasons: warmth, food, and water. Unlike summer months when food is abundant outdoors, winter conditions make survival more challenging, prompting rodents and insects to enter homes through even the tiniest cracks. Some of the most common winter invaders include:

• Mice and Rats – Seeking shelter in attics, basements, and walls.
• Spiders – Hiding in storage areas, corners, and unused rooms.
• Cockroaches – Finding warmth and moisture in kitchens and bathrooms.
• Silverfish – Thriving in humid environments like basements and laundry rooms.

Understanding why these pests enter your home can help you take proactive steps to keep them out, and often call for expert pest removal service.

2. Seal Entry Points to Keep Pests Out

Rodents and insects can enter through the smallest cracks and openings. Conduct a thorough inspection of your home’s exterior and seal off any potential entry points:

• Check windows and doors – Use weather stripping and door sweeps to prevent gaps.
• Inspect the foundation – Seal cracks with caulk or expandable foam.
• Close off vents and openings – Install fine mesh screens over vents and chimneys.
• Repair damaged roofing and siding – Pests can squeeze through loose shingles and gaps in siding.

Freezing temperatures impact household pests and how sealing entry points can keep them from entering your home. A gap the size of a dime is enough for a mouse to enter your home. Sealing these entry points is one of the most effective ways to prevent infestations.

3. Store Holiday Decorations Properly

Properly organizing boxes helps prevent rodents and insects from making your attic their winter home.

Holiday decorations, especially those stored in attics and basements, can be a breeding ground for pests. Cardboard boxes attract rodents and insects, so it’s best to store decorations in airtight plastic containers. When bringing decorations down for the season:

• Inspect for signs of pests – Look for droppings, gnaw marks, and nests.
• Shake out artificial trees and wreaths – Spiders and insects often hide in stored greenery.
• Vacuum storage areas – Regular cleaning helps remove crumbs and debris that attract pests.

4. Keep Food and Waste Secure

The holidays often mean an abundance of food, and if not stored properly, it can attract pests. Here’s how to minimize the risk:

• Store food in airtight containers – Avoid leaving leftovers uncovered.
• Take out the trash regularly – Keep trash bins sealed and away from entry points.
• Clean up crumbs and spills immediately – Even small amounts of food can draw pests.
• Inspect groceries before storing – Pests like pantry moths and beetles can hitch a ride in dry goods.

Rodents can spread harmful diseases through contaminated food and droppings, making proper food storage essential. Make sure to seal up your home to prevent rodents, reducing the likelihood of infestations caused by improperly stored food and open waste areas.

5. Maintain Your Home’s Exterior

Stack firewood at least 20 feet from your home to reduce the risk of rodents and insects seeking shelter during the winter months.

Your yard and home exterior can play a big role in pest prevention. Reduce pest-friendly environments by:

• Keeping firewood at least 20 feet from the house – Woodpiles attract rodents and insects.
• Trimming trees and shrubs away from your home – Overhanging branches provide easy access.
• Clearing gutters and drains – Standing water attracts mosquitoes and other pests.
• Fixing leaks and moisture issues – Many pests thrive in damp environments.

Winter pest-proofing is key, including how to keep mice and spiders out during winter with proper home maintenance.

6. Set Traps and Use Natural Deterrents

If you suspect pests are already inside, take action before the problem worsens. Some effective pest control methods include:

• Mouse traps – Snap traps and bait stations work well for rodent control.
• Diatomaceous earth – A natural, non-toxic powder that dehydrates and kills insects.
• Peppermint oil for mice – Strong scents like peppermint can deter rodents from entering.
• Glue traps for spiders and insects – Place them in corners and along baseboards.

If an infestation persists, professional pest control services may be necessary to remove the problem safely and effectively.

7. Regular Home Inspections and Professional Pest Control

Even with the best prevention methods, some pests can still find a way inside. Regular inspections from a licensed pest control service can help identify and address issues before they escalate. Benefits of professional pest control include:

• Targeted treatments for specific pests
• Eco-friendly options that minimize chemical exposure
• Expert advice on long-term prevention
• Hiring a professional is especially important for severe infestations or homes with recurring pest problems.
