You might hear scratching, thumping, or even high-pitched squeaks from above your ceiling. Those noises usually mean squirrels have moved into your attic and are tearing up insulation, chewing wires, and making a mess of whatever you’ve stored up there.
You can spot squirrels by listening for daytime noise, finding chewed entry points or acorns, and seeing droppings or nests in the insulation — and you can remove them humanely with exclusion doors, sealing, and cleanup. Here’s how to confirm they’re there, get them out safely, and stop them from coming back.
Let’s break down some easy checks to spot squirrel activity, steps to get them out without hurting babies, and practical fixes to seal up entry points so your attic stays squirrel-free.
How to Identify Squirrels in Your Attic
Listen for daytime scampering. Check for shredded nesting material.
Look at wiring and vents for chew marks. Inspect where insulation is torn, near eaves, and around the roofline for possible entry points.
Recognizing Squirrel Noises and Activity
You’ll often hear quick footsteps and soft thumps above your ceiling during the day. Squirrels move in short bursts, so expect those noises at dawn and late afternoon when they’re most active.
Their scratching and chewing sounds are higher-pitched than rats. If you hear repeated gnawing near rafters or vents, squirrels are probably chewing wood or wires.
A sudden loud thump? That’s probably a squirrel jumping between beams.
Watch for daytime activity on your roof or in nearby trees. Squirrels use branches to reach the roof.
If you see them circling the same spot or slipping into gaps under the eaves, that’s likely their entry route.
Spotting Squirrel Droppings and Nests
Squirrel droppings are small, brown, and pellet-shaped—usually a bit bigger than mouse droppings. You’ll find them in attic corners, on the floor, or tucked into insulation.
Look for nests made from shredded insulation, leaves, paper, or even bits of fabric. These nests are usually round, about a foot wide, and hidden in corners or behind ducts.
Fresh nesting material looks cleanly torn and recently arranged.
The smell can help too. Urine and droppings create a musty or ammonia-like odor.
A stronger rotten smell? That could mean a dead animal.
Wear gloves and a mask when you check droppings or nests—nobody wants to mess with parasites or bacteria.
Common Entry Points and Damage Signs
Check soffits, roof vents, chimney gaps, and loose fascia for holes about the size of a fist or bigger. Squirrels chew through wood and widen small gaps, so look for fresh bite marks and splintered wood.
Inspect attic insulation and beams for shredded or chewed spots. Squirrels rip up insulation for nests, leaving clumps or bare patches.
Look for bite marks on stored boxes or torn fabrics near the nest.
Pay close attention to electrical wires. Squirrels chew wire insulation, which exposes copper and increases fire risk.
If you spot frayed or freshly gnawed wires, don’t use the area—call an electrician or wildlife pro to fix and seal things up.
Effective Squirrel Removal Solutions
You need a plan to get rid of squirrels safely, keep them out, and protect your wires, insulation, and stored stuff. Focus on humane exclusion, safe trapping, and repellents that actually do something. Sometimes you just have to call a pro.
Humane Squirrel Removal and Exclusion
First, find every entry point—look for gaps under soffits, torn vents, and holes along the roofline. Seal small gaps with galvanized hardware cloth or sheet metal.
For bigger holes, use exterior-grade plywood or flashing plus heavy-duty mesh. Try to make repairs from the outside so you don’t accidentally trap any squirrels inside.
Install one-way exclusion doors at a known exit so squirrels can leave but not come back. Leave them up for about 3–5 days and watch for any activity.
Don’t seal the last exit if you think babies might be inside—try to check during non-breeding months if you can. Trim tree limbs at least 8–10 feet from your roof to cut off their access.
Using Squirrel Traps and Bait Safely
If you’re using traps, pick a live-capture cage sized for tree squirrels. Place traps where you hear activity—along rafters or at the edges of the attic floor.
Bait them with unsalted peanuts, sunflower seeds, or apple slices. Check traps at least twice a day to keep stress down for any trapped animals.
Make sure you follow local laws. Some places have rules about how far you can relocate wildlife or require permits.
Release squirrels at least 3 miles away if the law allows it and it’s safe. Always wear gloves when handling traps and clean them after use to avoid spreading disease.
If you find babies, don’t remove a nursing mother without getting professional advice.
Squirrel Repellents and Proven Deterrents
Repellents can help while you seal up openings. Some commercial repellents use predator urine and work outdoors around feeders or vents.
Indoors, you might try pepper-based sprays, vinegar-soaked rags, or naphthalene alternatives to nudge squirrels out. But skip mothballs in living areas—they’re risky for your health.
Combine repellents with bright lights and constant noise (a radio or timed lights) to make the attic uncomfortable. Motion-activated lights or ultrasonic devices add another layer, though honestly, don’t count on them alone.
Remove food attractants: secure your garbage, stop feeding birds near the house, and store pet food in sealed containers.
When to Contact a Professional
You should call a wildlife removal expert if you keep hearing scratching in your walls, notice chewed-up wiring, or smell something foul that might be coming from a nest.
These professionals know how to handle things humanely. They’ll check for babies, make sure animals can’t get back in, and fix any damage for good.
They can install one-way doors that actually fit, use flashing and hardware cloth to seal up tricky entry points, and take care of legal relocation.
Choose a company that has proper wildlife removal credentials and insurance. It’s smart to ask them about their humane methods, proof of exclusion, and whether they offer a warranty on their repairs.
If you feel more comfortable with a big-name company like Terminix or Orkin, ask for local reviews first. Local wildlife removal specialists might surprise you, so give them a look too.
