Do you suddenly wake up in the middle of the night? It may not be insomnia, but it may be that your sleep is being interrupted by the pitter-patter of squirrels nesting in your attic. You likely have squirrels if you hear light scurrying, scratching noises, the sound of small objects (like acorns) rolling around in your attic, and you spot small foul-smelling pellets with rounded ends (rat poop has sharp ends) in your garage or around your property. Learn more about how and why squirrels prefer nesting in attics and how you can try eliminating them from your house yourself before calling in the pros.
How Do Squirrels Get Into Attics?
Squirrels love attics because they are uninhabited, warm, dry, high up, and protected from predators. But the most important reason for squirrels to hide out in attics is to have babies. Once they take up residence in your attic, they will use their urine to mark the space as their territory. In spacious attics, they will use one end as a nesting area and the other end as a latrine. There's also plenty of room to stash their food supply of nuts.
These innocent-looking pests are agile jumpers and destructive chewers, which is why they can get into attics so easily. When squirrels want to get into an attic, they can do the following:
- Push in bricks on chimneys
- Climb brick or stucco buildings in seconds
- Pull apart terra cotta and slate roofs
- Chew through shingles, wood, aluminum, and high, hard-to-reach parts of the roof
- Squeeze themselves through holes or missing fascia boards along the roofline
How to Prevent Squirrels From Nesting in Attics
There are preventable measures from keeping squirrels out of your attic. You will want to make your attic extremely unattractive and uncomfortable for nesting squirrels. To do this, immediately follow these steps:
- Remove bird feeders as a food source from your property, place squirrel-proof bird feeders far away from your house, or trick the animals from climbing them .
- Secure the garbage cans to limit more sources of food.
- Cut the tree limbs back around the house so squirrels do not have easy access to the roof.
- Check your chimney cap and make sure it doesn't need to be replaced.
- Repair rotting wood on your fascia which causes inviting holes.
How to Get Squirrels out of the Attic
If you're too late and squirrels have taken up residence upstairs, shoo them away by creating a whirlwind of activity in and around your attic. Squirrels dislike when their space is inhabited or too loud. Try these steps before using any commercial squirrel repellants (which are typically formulated with predator urine):
- Make noise by banging on the ceiling and rafters with a broom handle or your hands.
- Talk and yell loudly into the attic or near the ceiling to startle them.
- Bang pots and pans together near the ceiling or at the entrance to the attic.
- Turn on a radio, television, or other ongoing music or sound and leave it playing day and night and it's better yet if you can leave it on in the attic.
- Turn on a bright spotlight or strobe light in the attic and leave it on night and day.
- Soak rags in cider vinegar and place them in the attic (they hate the smell).
- Place mothballs around the attic (they are repelled by that smell, too), but only if young children or pets cannot reach the space or inhale the fumes.
If the squirrels refuse to leave, it may be because they do not want to leave their babies behind. In this case, you can call in a professional to safely and humanely relocate the family. You can sleep soundly knowing the family is gone, but you will also need to immediately inspect and close all possible entry points the squirrels may have used to gain access to your attic.
