The short version
Signs of squirrels are daytime scratching in the attic, chewed wood and gnawed wiring, and a nest of shredded insulation. Unlike raccoons, squirrels are active in daylight — that's normal, not a sign of illness.
- Daytime scratching and chewed wood are the classic signs.
- A nest of shredded insulation is definitive.
- Daylight activity is normal for squirrels.
- The gnawing is the fire-risk sign.
For anyone who suspects squirrels are around the house and wants to confirm it.
What to look for
A squirrel can live in your attic for weeks before you see it — but the signs are there. Daytime scratching, chewed wood, a nest in the corner. Reading them early is what catches a denning squirrel before the litter arrives.
- 1Scratching, scurrying, and darting overhead at dawn and dusk — squirrels are daytime animals.
- 2Chewed wood, gnawed wiring, and shredded insulation in the attic.
- 3A gap as small as 1.5 inches in the roofline or soffit.
- 4A squirrel running along power lines or leaping from a tree to the roof.
- 5Nesting material — leaves, twigs, and shredded insulation — in an attic or wall.
- 6Morning and evening noise, when squirrels are most active.
Why it’s worth acting soon
- Squirrels gnaw constantly — chewed wiring is a fire risk.
- A denning squirrel shreds insulation and can damage the structure.
- Squirrels rarely carry rabies, but a cornered one will bite, and fleas and mites come with them.
- An open entry means the next squirrel moves in after the first is removed.

Inside, look for nests, droppings and flattened or soiled insulation.The sounds.
Daytime scratching, scurrying, and darting overhead — squirrels are active in the morning and evening. In spring and late summer, soft chittering from young means a mother is denning.
The chewed wood.
Chewed wood, gnawed wiring, and shredded insulation are the classic squirrel signs. Because their teeth never stop growing, the gnawing is constant — and it's the sign that points to the fire risk.
Gable vents without sturdy mesh are easy entry points.The nest.
A nest of shredded insulation, leaves, and twigs in an attic corner or wall void is definitive. Squirrel droppings — small, dark, scattered — come with it.
The tracks and routes.
Squirrels run along power lines, leap from trees, and leave four-and-five-toed tracks in dust. The route they use is the route to remove — trim it and seal it.
The daytime signature.
The single biggest sign is timing — squirrels are active in the morning and evening, so scratching at dawn and dusk is the giveaway. Nighttime noise points to mice, rats, or raccoons instead.
The gnawing.
Chewed wood and gnawed wiring are the signature damage, and they're constant — a squirrel's teeth never stop growing. Gnawed wiring is the sign that points to the fire risk.
The nest.
Scattered small droppings come with it. A nest of shredded insulation, leaves, and twigs in an attic corner or wall void is definitive. The nest is the sign that a squirrel is living there, not visiting.
The routes.
Squirrels run power lines, leap from trees, and leave four-and-five-toed tracks in dust. The route they use is the route to remove — trim it and seal it.
Reading the signs together.
Daytime scratching plus chewed wood plus a nest is a denning squirrel. One sign is a maybe; several are a pattern. Use the pattern to decide — a visitor needs prevention, a denning squirrel needs removal, exclusion, and cleanup.
Signs by season.
In fall, listen for activity as squirrels seek winter shelter. In late summer, the second breeding season brings the same. In spring, listen for young chittering and look for a mother denning. The season tells you what to look for.
The fire-risk sign.
Of all the signs, gnawed wiring is the one that demands action now — it's a fire risk, and the gnawing continues until the squirrel is out. If you see chewed wiring, treat it as urgent.
Signs vs. sightings.
A sighting is the squirrel itself. A sign is evidence of a squirrel-friendly home — the gap, the branch, the feeder — even if you haven't seen the squirrel. Both matter, but the signs are the ones you can act on early.
When signs are seasonal.
A little scratching in spring and late summer is the breeding rhythm; steady scratching week after week is a denning squirrel. Use the season as context before you escalate.
Signs a professional looks for.
A pro checks the roofline and vents for the entry, then the attic for the nest and the gnawing. Knowing what they look for helps you hand them a better picture — and judge whether their findings match what you've seen.
The route signs.
A squirrel running a power line, a branch touching the roof, and four-and-five-toed tracks in dust are all route signs — they show how the squirrel is getting onto the house. Remove the route and you remove most of the problem.
Signs that travel indoors.
A squirrel in the living space, or droppings in the attic, are signs the animal is close — or has been. Every indoor sign is a data point: note where it was and when, and you'll know which entry to focus on.
Confirming with a look.
A nest of shredded insulation plus a gap over 1.5 inches is confirmation. To confirm the signs, check the attic for a nest and the roofline for a gap. If you can't see it, a professional's inspection will.
Reading a drag or visual check.
You don't need special tools to confirm a squirrel — a look at the roofline for a gap and the attic for a nest is enough. The nest and the gnawed wood are the confirmation, and they're the evidence a professional uses to scope the job.
Signs in the yard.
A feeder knocked down or raided is classic too. Chewed bark, dug-up garden beds, and a squirrel burying nuts are ground-level signs that a squirrel is nearby. These yard signs tell you where the squirrel is feeding, which is where to focus the prevention.
What affects the price
- Whether squirrels are denning in the attic versus just passing through the yard.
- The number and location of entry points that need sealing.
- Whether a litter is present in a wall or attic.
- Whether gnawed wiring or insulation needs repair.
- The amount of cleanup and insulation replacement needed.
- Emergency or same-day calls.

What is your biggest concern about a squirrel infestation?
When to call for help
Call a professional when a squirrel is denning in the attic or walls, when you hear it in a wall void, or when gnawed wiring points to a fire risk. A one-way door handles the removal humanely, and a provider will check for a litter so none are left behind.
What you can do yourself
Leave the removal to a professional. What isn't yours is the squirrel itself — the one-way door needs timing so no litter is left behind, and a cornered squirrel will bite. Prevention is safely yours: seal the gaps, trim the branches, and secure the feeders.
Where you live matters
In Signs Of Squirrels, keeping a short dated note of where and when activity appears makes the next inspection faster and helps the provider focus on the right areas instead of treating the whole property. In Signs Of Squirrels, most providers include a follow-up visit in the plan, but the terms vary, so ask exactly what is covered and for how long before you decide. In Signs Of Squirrels, comparing written quotes side by side is the easiest way to see what is actually included, because the scope, prep steps, and follow-up terms vary a lot between providers. In this area, the local climate means squirrels activity tends to follow the warmer months, so scheduling the visit before the busy stretch usually means a faster response and a cleaner quote. Removal is usually done with a one-way exclusion door, and their constant gnawing makes attic wiring a fire risk. Squirrels are found nationwide and are daytime animals that den in attics.
Simple ways to keep squirrels away
- Seal every gap larger than 1.5 inches in the roofline, soffits, and vents.
- Cap the chimney and screen vents and soffits with sturdy mesh.
- Trim tree branches back at least 6 to 8 feet from the roof.
- Keep bird feeders away from the house or switch to squirrel-resistant ones.
- Repair loose or damaged roofline trim before squirrels widen it.
- Check the roofline each late winter and late summer, before the breeding seasons.
Seal gaps with metal mesh or flashing. Squirrels chew straight through foam.Did you know?
Squirrels can rotate their ankles 180 degrees, letting them climb down trees headfirst.
A squirrel's front teeth never stop growing, which is why it gnaws constantly.
Squirrels use elaborate fake-burying tactics to fool other animals trying to steal their food.
