Find out what's making noise in your attic

If you're hearing noises up on the rooftop, it's still a little too early to chalk it up to being Santa Claus and his reindeer. Just like you're enjoying the warmth and comfort of your home as temperatures drop outside, outdoor critters are hastily trying to find reliable and protected shelter for them and their furry families. Pests like squirrels are ready to build a nest somewhere that doesn't have the threat of predators or prolonged exposure to low temperatures. So how do squirrels get into an attic?

Common Entry Points in Your Attic

You've checked your roof for holes or damage and haven't found anything, so your attic is safe this winter from squirrels, right? Unfortunately, squirrels are incredibly crafty and persistent, so they will find and use any possible way inside your attic. This means openings that are necessary to have, like ridge vents, gables, and plumbing mats, are possibly allowing pests to enter your home.

Squirrels are also not above chewing their way into a potential shelter from the cold temperatures. Even if you've done a visual check of your roof, there may be hidden places where squirrels have gnawed their way through siding or roofing.

Signs You May Have Squirrels (Or Other Pests) In Your Attic

Squirrels aren't the only critter you might hear making noise in your home's attic. Here are some common signs you have an animal in your attic:

  • Scratching or scurrying noises: Probably the first sign homeowners mention noticing when they call for a pest inspection is "scratching noises" or "something running around up there." A key clue that might point to which pest you're dealing with is when you hear these noises. If the noises mainly happen during the day, you're likely dealing with squirrels in your attic. If the noises happen mostly during the night, it's possible you have rats or mice in the attic instead of squirrels.

  • Chewed wires and wood: Rodents love to chew, thanks to their front teeth constantly growing. If they are camped out inside your home, they don't have access to their usual outdoor chew toys, so they target the next best (and closest) things: electrical wiring, edges of the wooden attic beams and joists, and cardboard.

  • Nests in insulation or disturbed boxes: Take a look at the insulation in your attic. If some of it seems like it's been moved into more of a mound or pile, you might have some rodents hiding out with their babies. If you have cardboard boxes in your attic, check the corners to see if any holes have been chewed. To prevent rodents from nesting in your valuables, replace any cardboard storage with plastic bins with tight locking lids.
