During the winter, animals look for any way possible to stay warm and among their favorite ways is finding an entrance into your attic. This can lead to all kinds of unwanted noise and damage, so it’s important to take preventive measures in keeping raccoons out of the attic.
Checking For Holes/Gaps:
Raccoons enter through holes or gaps in the roof that are not always obvious to the homeowner. These gaps can be vent fans located on the roof, open areas beneath the eave of the house, and of course poorly covered holes caused by damage to the roof. They are incredibly smart, versatile, and strong so always do a full check of the roof and underneath the overhangs to make sure there are no spaces for the raccoon to squeeze through.
Sealing These Holes/Gaps:
Raccoons are some of the hardest animals to keep out of your attic because they are so incredibly skilled and determined. Unlike many animals, they are able to use their hands to rip open metal meshing that blocks vents and gaps in the eaves of the home. Standard aluminum mesh should never be used to seal a hole as this material is very easy for raccoons to demolish. Despite their size, they are quite strong. Instead, a strong form of wire meshing, such as steel, should be used. This type of meshing should always be secured to the home with several screws to prevent the animal from pulling it off and gaining entrance. Expanding foam is also useful in closing small gaps that a raccoon could potentially work into a bigger hole. This foam blocks the hole and expands to cover it fully and also expands several inches into the hole. Boarding up the hole is also useful in deterring raccoons, just make sure that it is nailed down securely to prevent paws from prying it off.
