Quick Answer
To seal gaps against squirrels, use 1/4 inch hardware cloth, expanding foam, and 1/8 inch metal mesh. These materials are effective for blocking entry points. Regular checks and maintenance are essential to prevent re-infestation.
Choosing the Right Materials
When selecting materials for sealing gaps, consider the size of the openings and the type of pest you’re trying to exclude. For smaller openings, use 1/4 inch hardware cloth, which is a sturdy metal mesh that will prevent squirrels from gnawing through. For larger openings, use expanding foam, which can be molded to fit the space. This type of foam is also effective at sealing gaps around pipes and electrical outlets.
Sealing Gaps with Expanding Foam
To use expanding foam, spray the foam into the gap, holding the can upright to prevent foam from flowing back out. Hold the can in place for a few seconds to allow the foam to set, then remove it. Allow the foam to fully dry and harden before covering it with additional materials, such as metal mesh or hardware cloth.
Additional Tips and Considerations
When sealing gaps, it’s essential to check the area regularly to ensure that the materials are still effective. Check for signs of re-infestation, such as gnaw marks or droppings, and reapply materials as needed. Additionally, consider using 1/8 inch metal mesh to cover vents and other openings, as this will also prevent squirrels from gaining access to your cabin.
