Squirrel Control for Homeowners

For a homeowner, a squirrel problem is usually an attic problem — and the fix is remove, seal, and trim. Here's where they get in, what they gnaw, and what to do.

The short version

For homeowners, squirrel control is three jobs: remove the squirrel with a one-way door, seal the roofline, and trim the branches. Do the prevention yourself and hire a professional for the removal.

  • Squirrels get in through the roofline.
  • Remove, seal, and trim — three jobs.
  • Chewed wiring is a fire risk.
  • Prevention is DIY; the one-way door is not.

For homeowners who hear scratching in the attic or see squirrels on the roof.

What to look for

They're daytime animals that gnaw constantly, which makes attic wiring a fire risk. Squirrels den in attics and walls, entering through gaps as small as 1.5 inches. The problem is the open gap and the overhanging branch — not the one squirrel you see.

  • Scratching, scurrying, and darting overhead at dawn and dusk — squirrels are daytime animals.
  • Chewed wood, gnawed wiring, and shredded insulation in the attic.
  • A gap as small as 1.5 inches in the roofline or soffit.
  • A squirrel running along power lines or leaping from a tree to the roof.
  • Nesting material — leaves, twigs, and shredded insulation — in an attic or wall.
  • Morning 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.

Where they get in.

Squirrels enter through the roofline — soffits, vents, and eaves — and any gap larger than 1.5 inches. Overhanging branches make those entries easy.

The fix, in order.

Remove the squirrel with a one-way door, seal the roofline, and trim the branches. Do all three or the next squirrel moves in.

The prevention that lasts.

Sealed gaps, trimmed branches, and secured feeders keep squirrels out for good — and they're work you can do yourself.

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 squirrels in your attic?

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

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. Leave the removal to a professional. Prevention is safely yours: seal the gaps, trim the branches, and secure the feeders.

Where you live matters

The best estimate reflects the size of the space, the level of activity, and the specific conditions the provider actually saw. Squirrels are found nationwide and are daytime animals that den in attics. Removal is usually done with a one-way exclusion door, and their constant gnawing makes attic wiring a fire risk. The most useful first step in Homeowners is to note where you have seen squirrels activity and when it appears, so an inspection is faster and the quote more accurate. In Homeowners, checking the usual entry points, moisture spots, and sheltered areas near the structure usually turns up the conditions that are letting them in. A local provider who knows Homeowners can point out the specific things that matter most here before you commit to a plan. In Homeowners, before you book, ask whether the inspection is included, what the treatment plan covers, how many visits to expect, and what the written quote includes. In Homeowners, getting the scope, the prep steps, and any follow-up terms in writing makes it much easier to compare providers fairly, and a good provider will walk you through each of these without pressure. In Homeowners, a little preparation usually makes the visit more useful: clear access to the areas where you have seen activity, put away loose items, and note anything you have noticed recently. In Homeowners, if you have photos or a rough timeline of when the problem started, share them, because those details help the provider confirm what is going on and give you a more accurate scope and price. In Homeowners, after treatment, ask what to watch for and when a follow-up visit would make sense. In Homeowners, most problems do not disappear after a single visit if the conditions that caused them are still present, so the plan should spell out what changes afterward and how you will know it worked. Prevention is the part that keeps the problem from coming back. In Homeowners, that usually means sealing the gaps and moisture issues the inspection turned up, adjusting what is stored near the structure, and staying on top of the small warning signs before they become a bigger job. Most bat work is about the roofline and the attic. In Homeowners, bats squeeze through gaps as small as three-eighths of an inch, so an inspection looks closely at ridge vents, gable vents, soffits, and the joints where the roof meets the wall. In Homeowners, a short watch at dusk is often the clearest way to confirm where they are getting in and out. In Homeowners, if you have seen a bat indoors, keep the room closed and do not handle it bare-handed. In Homeowners, a bat found in a room where someone was sleeping, or one that may have touched a child or pet, is treated as a possible exposure, so contact public health or a doctor before releasing it. In Homeowners, exclusion is the durable fix: one-way devices let the bats leave but not return, and then every remaining gap is sealed. In Homeowners, it has to be timed outside the maternity season so young bats are not stranded inside, which is why it is usually a professional job rather than a do-it-yourself one. In Homeowners, droppings and urine build up under a long-standing roost, and cleaning them disturbs dust that can carry spores, so cleanup should be done with the right protection and often as a separate scope from the exclusion work itself. In Homeowners, ask for everything in writing before you commit: the scope, the price, the preparation steps, and what happens if the problem returns. In Homeowners, providers that are clear about these up front are usually the easiest to work with. In Homeowners, schedule the inspection when you have time to walk the property with the provider. In Homeowners, seeing where the activity is and asking questions in person usually leads to a better plan than a quote over the phone. In Homeowners, keep a short note of when you first noticed the issue and what you have tried. In Homeowners, that timeline helps the provider understand how long the problem has been building and what is most likely to work. Compare at least a couple of written quotes before deciding. In Homeowners, the lowest price is not always the best value if it leaves out a follow-up visit or a key part of the treatment. In Homeowners, after the work is done, ask what changed and what to watch for next season. In Homeowners, good pest control is as much about prevention as it is about treatment, and the best plans include both. A good provider starts with the problem, not the product. They should explain what they found, why they recommend a particular approach, and what the realistic outcome looks like before they ask you to sign anything. Small problems are usually cheaper and faster to resolve, so acting on the first reliable sign of activity is almost always the most economical choice. Waiting tends to grow the affected area and the bill. Different properties need different plans, so be wary of any quote that sounds identical for every home.

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.
