How to Keep Rodents Out of Your Crawl Space This Winter

As temperatures drop, many homeowners face a common challenge: rodents seeking warmth and shelter indoors. Crawl spaces are especially vulnerable to these unwelcome visitors. The good news is that with the right steps, you can protect your home and keep rodents out during the colder months. Here’s how:

1. Seal All Openings in Your Foundation

Rodents can squeeze through surprisingly small gaps—some mice only need a hole the size of a dime! Carefully inspect the exterior of your home, paying close attention to the foundation, vents, and any utility entry points. Seal any cracks or holes using materials like caulking, steel wool, or expandable foam to ensure that no tiny intruders find their way in.

2. Apply a Moisture Vapor Barrier

Rodents are attracted to crawl spaces with moisture, as these conditions are ideal for their nests. By installing a high-quality moisture vapor barrier on the floor of your crawl space, you create an environment that is less inviting to pests. These barriers also help to maintain a healthier space by preventing mold and reducing humidity.

3) Sealing off or closing crawlspace vents

Additional Tips for Winter Rodent Prevention

• Keep the Area Clean: Remove debris, leaves, or clutter near your foundation where rodents might hide.

• Trim Vegetation: Ensure that bushes, shrubs, or tree branches are trimmed away from your house to eliminate bridges for rodents to climb.

By taking these steps, you can help keep your crawl space rodent-free this winter while maintaining the integrity and comfort of your home.
