If you find a squirrel inside your home, it can feel pretty sudden—and honestly, a bit stressful. Still, you’ve got this. When a squirrel’s in your house, try to keep a clear path to an exit, shut other doors, and give it space while you figure out what to do.
Let’s talk about how to spot the signs of squirrels, why they sneak indoors, and the best ways to get them out and keep them out. This guide covers quick actions, humane removal, and some straightforward fixes to help you squirrel-proof your place.
Identifying and Understanding Squirrels Inside Your Home
You might spot chewing marks, hear rustling in the walls, or find droppings up in the attic. These signs usually reveal where squirrels are hanging out, how they got in, and what type you’re dealing with.
How Squirrels Get Inside Walls and Homes
Squirrels squeeze through small gaps that are easy to miss. They slip in through holes near rooflines, soffits, vents, or where wires and pipes meet the house.
Loose shingles, worn fascia, and cracks at the chimney base are classic weak spots. Once they’re in the attic or crawlspace, they chew through soft stuff to make bigger holes and reach wall spaces.
Tree squirrels jump onto your roof from branches nearby. Ground squirrels dig around foundations and sometimes sneak in through vents or cracks near the slab.
Check both the roof and ground-level spots if you’re hunting for entry points.
Main Types of Squirrels Found Indoors
Tree squirrels—like eastern gray and fox squirrels—usually end up in attics and wall cavities. They climb trees, fences, and even power lines to reach the roof.
You’ll find their nests in insulation, and they leave gnaw marks on wood and wires. Ground squirrels aren’t as likely to move into walls, but they might show up in basements or crawlspaces if they find a way in.
Flying squirrels, which are smaller and active at night, also nest in attics. Their droppings pile up near insulation.
Common Entry Points and Signs of Squirrels
Check for roof vents without screens, gaps under soffits, broken chimney flashing, ripped shingles, and torn vent covers. At ground level, look at foundation vents, spaces around pipes, and holes under porches.
Listen for running, scratching, or thumping in the attic, especially early or late in the day. Watch for squirrels darting across your roof or hanging out in the gutters.
Look for fresh gnaw marks, insulation that’s been moved, and nests made from leaves and insulation stuffed into corners.

Squirrel Droppings and Other Indications
Squirrel droppings are small, rounded pellets—usually 3–8 mm long, dark brown or black when fresh. You’ll see them in attic corners, along beams, or near nests.
Droppings look a bit like other rodents, so check the size and shape to tell them apart from mice or rats. Other signs include greasy marks where squirrels run, shredded paper or insulation for nests, and chew marks on wood or wires.
If you notice a strong musky or urine smell, that’s a clue they’ve been around for a while. If you spot droppings or chewed wires, don’t touch them—think about calling a pro for cleanup and repairs.
Managing Squirrels Indoors: Removal, Damage, and Prevention
Here’s what to look for in terms of damage, how to get squirrels out safely, and the most practical ways to keep them from coming back.
Potential Damage Caused by Squirrels
Squirrels chew on almost everything. They can gnaw through electrical wires, which is a real fire hazard, and they rip up insulation to build nests.
If you see exposed wires, scorch marks, or outlets that don’t work, those might be signs. Nests in attics or walls leave urine and droppings that stain insulation and create nasty smells.
You might notice greasy smudges at entry points or piles of nesting stuff in vents and rafters. Squirrel droppings are bigger and rounder than mouse droppings.
Squirrels chew up soffits, make holes in fascia, and tear roof underlayment. Small holes by rooflines or vents are their doorways.
Repairs for wiring or insulation often cost more than simple removal, so keep track of those expenses.
Effective Squirrel Removal Techniques
Start by finding where squirrels get in and when they’re active. Listen for them in the attic at dawn or dusk.
Use a flashlight to spot new gnaw marks, droppings, or nests. Install one-way exclusion doors on the holes you find—these let squirrels leave but stop them from coming back.
Live traps with peanut butter can work if local rules allow you to relocate them. Always check the laws before trapping or moving any animals.
If you find lots of squirrels, babies, or chewed electrical wires, call a licensed wildlife control pro. They’ll handle removal, cleanup, and repairs.
Usually, attic cleanup and wire repair cost more than just trapping. It’s worth considering if you want the job done right.
Preventing a Squirrel Infestation
Seal every opening larger than half an inch using heavy-duty materials like steel mesh or hardware cloth. Pay special attention to soffits, vents, rooflines, and any gaps you find near chimneys.
Skip foam or thin wood—squirrels will just chew right through those. It’s honestly surprising how persistent they can be.
Get rid of food temptations: lock up your trash bins, pick up any fallen fruit, and swap out your bird feeders for squirrel-proof ones. Trim tree branches so they’re at least eight feet away from your roof.
Don’t leave pet food outside, and always keep compost bins tightly closed. Squirrels seem to find any excuse to stick around if there’s food.
Check your roof and attic twice a year. Replace any damaged flashing and make sure to screen your vents.
If you notice fresh chew marks, jump on repairs right away—fixing things early can keep a minor squirrel problem from turning into a headache.
