You might already suspect a squirrel if you hear scratching in the attic, spot chew marks, or catch a faint, musky smell.
If you notice noises above your ceiling, fresh droppings, or damaged screens, there’s a good chance a squirrel has found its way into your home. Those signs should nudge you to act before things get out of hand.
Try to stay calm and focused.
This post will help you figure out if it’s really a squirrel problem, show you how to spot entry points, and share steps for getting squirrels out—and keeping them out.
Keep reading for practical tips that can protect your house and, honestly, help you sleep a little easier.
Recognizing Signs of a Squirrel in Your House
Watch and listen for the obvious stuff: weird noises inside your walls or attic, droppings, bits of nest material, or chewed-up wiring and wood.
These signs usually point right to where squirrels sneak in and travel.
Audible Clues: Scratching and Scampering Sounds
You might hear scratching, scampering, or even soft thumps in the ceiling, walls, or attic.
Tree squirrels usually get noisy at dawn and dusk, while flying squirrels make their racket at night.
Notice when the sounds happen.
If you keep hearing movement in the morning or late afternoon, you’re probably dealing with daytime squirrels.
Noises after sunset? That’s usually flying squirrels.
Try to pinpoint where the sounds come from.
Scratching near vents, eaves, or the chimney often means you’ve found an entry point.
If you hear scratching in one spot over and over, it could be a trapped animal.
Jot down when and where you hear these sounds for a few days—it helps spot patterns before you go poking around.
Physical Evidence: Droppings, Nesting Materials, and Damage
Squirrel droppings look brown and tube-shaped, about 3/8 inch long.
If you see a bunch of them in one place—especially in the attic, crawlspace, or near a roof hole—you likely have a squirrel problem.
Wear gloves if you need to clean them up and bag them safely.
Look for nests built out of shredded insulation, leaves, paper, or even bits of clothing.
Squirrels love to stash acorns or seeds near their nests.
Check rafters, vents, and attic corners for chewed insulation or little twigs.
On the outside, inspect eaves and fascia for small entry holes—nickel- to quarter-sized is all they need.
Chewed Electrical Wires and Property Risks
Squirrels constantly gnaw to keep their teeth in check, and they often chew on wires in attics and basements.
Exposed or frayed wires can spark short circuits and even start fires.
If you spot bite marks on wires or see scorch marks, treat it as a real safety problem.
Don’t mess with damaged wiring yourself.
Turn off the power in that area and call a licensed electrician.
After you’ve dealt with the squirrel, seal up any entry points to keep them from coming back.
Trimming tree branches that touch your roof also helps cut down on squirrel access.

How to Prevent and Remove Squirrels From Your Home
You can usually stop squirrel problems by finding their entry points, using safe removal methods, and fixing up gaps around your roof and vents.
Focus on sealing holes, picking a humane removal method if one’s stuck inside, and upgrading fixtures outside to block them in the future.
Common Entry Points and How Squirrels Get In
Squirrels can squeeze through holes as small as 1.5 inches.
Check eaves, attic vents, soffits, gaps around the roofline, loose siding, and spots where pipes or cables poke through.
Chimneys and uncapped roof vents are also favorite routes.
Look for chewed wood, fresh droppings, greasy rub marks, or shredded nesting stuff near any opening.
If tree branches touch your roof, that’s a squirrel highway.
Trim branches so there’s at least a six-foot gap from the roof to the nearest limb.
After big storms, make sure to check for new gaps where flashing or shingles might have shifted.
Squirrel Removal Methods: DIY and Professional Options
If you see a squirrel loose inside, open a clear exit and shut other doors.
Leave a bright window or door open and make a bit of noise from a distance to nudge it out.
For attic or wall infestations, a one-way exclusion door lets squirrels leave but not come back.
Use humane live traps for relocation if your local laws allow it.
Skip glue or lethal traps—they’re risky for pets and other wildlife.
If you find a nest with babies or think there’s more than one adult, call a licensed wildlife removal company.
Pros can handle permits, safely remove families, and fix up any damage.
They’ll also release the animals humanely and set up exclusion devices the right way.
Preventative Steps: Sealing Entry Points and Exterior Upgrades
Seal up gaps with stuff squirrels can’t chew—like 1/4-inch hardware cloth, galvanized steel flashing, or metal vent covers.
Use exterior caulk and expanding foam for small cracks, then cover with metal or wood.
Replace any rotten fascia or trim to get rid of weak spots.
Install chimney caps and cover attic vents with sturdy mesh.
Secure soffit vents and close gaps around dryer vents with a one-way flapper or metal cage.
Don’t forget to check and reinforce garage eaves, roof seams, and places where utilities enter your siding.
Keep bird feeders away from the house, and try a squirrel-proof feeder to cut down on easy snacks.
Ongoing Protection: Wildlife Exclusion and Squirrel-Proof Solutions
Check your property twice a year—once in spring, then again in late fall. That way, you’ll spot new damage before it gets out of hand.
Keep a simple maintenance checklist handy. Trim back trees, look over your roof flashing, test those vent covers, and clear any loose debris from the eaves.
If you notice worn mesh or a damaged cap, swap it out right away. Don’t wait until it becomes a bigger headache.
Try using exclusion products. I’d go for sturdy one-way doors on attic openings and metal boot covers around pipe entries.
If squirrels keep messing up your garden, maybe try motion-activated sprinklers. They might surprise you with how well they work.
Long-term, you’ll want to get rid of food sources. Store pet food in metal containers, lock down your trash cans, and switch to bird feeders that squirrels can’t crack.
If the squirrels still come back—and sometimes they do—call a professional wildlife removal service. Let them figure out where the nests are and set up a real solution that lasts.
