Squirrels in your house often start as faint noises, but the situation can quickly spiral into costly damage. If you want to keep your sanity—and your wiring—intact, you’ll need a plan: figure out if squirrels are inside, get them out without hurting them, and make sure they don’t come back. It’s smart to act fast. Squirrel damage can fry your nerves, your insulation, and even your electrical lines, which seriously ups your risk of fire and pricey repairs.
You’ll pick up on the signs, learn how to evict squirrels safely, and find some cheap ways to seal up entry points and remove things that attract them. If you stick with this guide, you can turn all that scratching and scurrying into peaceful, quiet nights—and a house that feels like yours again.
Identifying and Understanding Squirrel Problems in the House
Start by listening for noises, checking insulation and vents, and watching your yard for extra squirrel activity. Look for obvious signs like droppings, chewed wood, or nests—they’ll tip you off to where the squirrels live and how they’re getting inside.
Signs of Squirrel Infestation
You might hear scratching, scurrying, or thumping in your attic, especially around dawn and dusk. The sounds often travel across rafters or right above your head.
Look for small piles of brown, oblong droppings—about 3/8 inch long—near entry holes or along attic beams. Fresh droppings are dark and soft, while old ones fade and harden.
Check for nests built from shredded paper, leaves, or insulation pushed into a cup shape. You’ll sometimes see acorns, shells, or food stashes left behind.
Notice any staining or strong urine smells drifting through vents. If you catch a whiff of something foul and pungent, a dead squirrel might be stuck in your wall or attic.
Types of Squirrels That Invade Homes
Gray squirrels usually cause the most trouble in attics. They’re active during the day and chew through wood and soffits to break in.
Flying squirrels are smaller and mostly come out at night. You might only spot them near attic vents after dark. They prefer tucked-away, insulated corners for their nests.
Ground squirrels don’t usually enter attics, but they dig near foundations or burrow under porches. You’ll spot their holes in your yard and maybe some seed piles.
Knowing what type of squirrel you’re dealing with helps you pick the right traps and exclusion materials. For instance, you’ll need smaller mesh for flying squirrels and tougher metal flashing for gray squirrels.
Common Entry Points for Squirrels
Check your roofline, especially where tree branches reach your house. Squirrels leap from branches onto roofs, so trim them back at least 6–8 feet.
Look for gaps around soffits, fascia, vents, and chimneys. Squirrels can squeeze through holes as small as 2 inches—and they’ll gnaw to make them bigger.
Inspect roof vents, loose flashing, and broken shingles. Utility lines that connect to your house work like squirrel highways.
Cover vents with metal mesh, and patch holes with sheet metal or 1/4-inch hardware cloth. Always make sure no animals are trapped inside before sealing things up.
Squirrel Damage to Homes
Squirrels chew through wood, trim, and fascia, creating holes and letting water seep in. Over time, chewed rafters and roof timbers can weaken your home.
They shred insulation for nests, leaving gaps that mess with your heating and cooling bills. Sometimes you’ll find insulation piled in corners.
Squirrels also gnaw on electrical wires and cable lines. That’s a major fire hazard and can knock out your power or cause shorts. Damaged wires need urgent attention.
Outside, they scatter birdseed, tear into trash bags, and strip bark from trees. If you see these signs in your yard, squirrels are probably close—or already inside.

Getting Rid of Squirrels and Preventing Future Infestations
If you spot chewing, hear scurrying, or find droppings in your attic, don’t wait around. Focus on removing squirrels safely, stopping the damage, and sealing every spot they might use to get in again.
How to Get Rid of Squirrels Safely
Don’t handle squirrels with bare hands. If you have to touch a trapped or stunned animal, wear thick gloves and long sleeves.
When a squirrel gets loose in your living space, open any doors or windows that lead outside. Get pets out of the room, then leave so the squirrel can find its own way out.
Never try to corner or grab a frantic squirrel. They bite and scratch, and that’s risky for disease. If you find a nest with babies, don’t seal exits until the young leave or a pro removes them—trapping adults while babies are inside just makes things worse.
If you’re unsure, call a licensed wildlife remover to capture and relocate the squirrel humanely.
Squirrel Removal Methods
Pick your method based on where the squirrel is—loose in a room, nesting in the attic, or stuck in the chimney. For a single squirrel indoors, try the open-exit method and gently herd it with a broom while keeping your distance.
For attic or wall infestations, install one-way exclusion devices over active entry holes. These let squirrels out but block them from coming back in, and they’re humane if you cover all the right spots.
Skip the poison. Rodent baits meant for rats can harm squirrels and pets, and often leave dead animals in your walls. If you hire professionals, they’ll handle removal, cleanup, and repairs. Lots of pest-control companies offer live-trapping and exclusion services.
If a squirrel is in your chimney, a chimney cap or even a rope for climbing can help it get out safely.
Squirrel Control and Deterrent Techniques
Change up what attracts squirrels to your place. Move bird feeders away from the house, keep pet food inside, and use metal bins with tight lids for seed and garbage.
Trim tree branches so they’re at least 6–8 feet from your roof. Squirrels can’t jump as far as you might think.
Try deterrents in attics and rafters: noise, bright lights, or rags soaked in vinegar can make the area uncomfortable for squirrels. Motion-activated lights or sprinklers can scare them off in the yard.
Some people use ultrasonic devices to irritate rodents, but honestly, results are mixed. If you have pets, test these carefully.
Preventing Squirrel Re-Entry
Take a good look at your roofline, soffits, vents, and foundation. If you spot gaps bigger than 1.5 inches, that’s a problem.
Seal those openings with heavy-gauge steel mesh, metal flashing, or hardware cloth. Don’t bother with wood or plastic—squirrels will just chew right through.
Pop a chimney cap on and toss pest-proof screens over the roof vents. That’ll block those sneaky entry points.
Trim back any tree limbs hanging close to your house. If you notice loose fascia or shingles, go ahead and secure them.
Swap out any busted vent covers and patch up holes around pipes or cables. After you finish sealing things up, it’s smart to remove old nests and droppings—though honestly, hiring someone for the cleanup makes life easier.
Once you’ve closed off every likely entry, keep an eye on the attic and roofline. Fresh chew marks or new debris might mean you’ve got more work to do.
