Sealing Garage Door Gaps: A Guide to Keeping Mice and Other Pests Out



The garage is often a common entry point for critters like mice, insects, and other pests. To prevent these unwanted guests from getting in, it’s important to regularly inspect and take action. Start by examining the perimeter of your garage door for any gaps where daylight is visible. Replace the bottom seal of the garage door if necessary to create a tighter barrier when closed. This will prevent pests from exploiting the gaps and gaining entry.

Seal small cracks with silicone caulk and use steel wool for larger gaps before applying caulk to deter rodents. Be on the lookout for signs of pests in your garage, as they can squeeze through tiny openings. Thoroughly check for any potential entry points.



Further tips for fortifying your garage against pests

If you have larger holes, consider using hardware cloth to cover ventilation openings or patch holes. Cut the cloth slightly larger than the gap and secure it with construction adhesive or a staple gun. Install a new threshold seal if your garage door doesn’t make full contact with the floor. These rubber strips can be cut to size and adapt to uneven surfaces, ensuring a tight seal.

Keep up with regular pest control methods by cleaning up messes in your garage, avoiding storing pet food or dry goods, and using products like diatomaceous earth along sealed edges to deter and kill insects. Check your seals seasonally for any expansion or contraction due to extreme weather conditions. Implementing a combination of methods will help keep your garage pest-free throughout the year.
