Homeowners insurance does not cover squirrel damage itself. Standard policies classify squirrels as rodents and exclude the chewed wiring, shredded insulation, gnawed framing, and contaminated attic spaces they leave behind. There is one important opening in that rule: if the squirrels trigger a separate covered peril, such as a house fire from a chewed wire or water damage from a chewed pipe, the resulting fire or water loss is usually covered even though the rodent damage underneath is not.
Why Squirrels Fall Under the Rodent Exclusion
The HO-3 homeowners policy, the most common form sold in the United States, excludes damage caused by “birds, vermin, rodents, or insects.”1Insurance Information Institute. HO 00 03 10 00 – Homeowners 3 – Special Form Squirrels belong to the order Rodentia, so insurers treat them the same way they treat mice and rats. The species does not matter; if a rodent caused the damage, the exclusion applies.
The reasoning behind the exclusion is that rodent damage develops gradually. Squirrels enter through a gap in the roofline, build a nest, and chew through materials over weeks or months. Insurers view that as a maintenance problem rather than the sudden, accidental loss homeowners insurance is designed to cover.
The exclusion sweeps broadly. It covers chewed electrical wiring, torn-up insulation, damaged ductwork, gnawed wooden beams, contaminated attic spaces, and holes in siding or soffits. Even if you had no idea the squirrels were there, the insurer will point to the exclusion and deny the claim for the rodent damage itself.
When Squirrel Damage Is Actually Covered
This is where most homeowners get the story wrong. While the rodent damage itself is excluded, the standard HO-3 policy contains an ensuing loss clause: “any ensuing loss to property described in Coverages A and B not precluded by any other provision in this policy is covered.”1Insurance Information Institute. HO 00 03 10 00 – Homeowners 3 – Special Form In plain English, if one bad thing leads to a second bad thing and that second thing is normally covered, the policy pays for the second thing.
Fire From Chewed Wiring
The most common scenario is fire. Squirrels chew through electrical wiring in an attic, the exposed wires arc, and the house catches fire. The chewed wiring itself is excluded rodent damage. Fire, however, is a covered peril under every standard homeowners policy, so the fire and smoke damage throughout the home would typically be covered. You will not be reimbursed for the wiring the squirrels destroyed, but you would receive coverage for the fire that followed.
Water From a Chewed Pipe
The HO-3 policy also contains a specific exception to the rodent exclusion for accidental water discharge. If a squirrel chews through a plumbing line and water floods part of your home, the resulting water damage may be covered. The policy covers loss from an accidental discharge or overflow of water from plumbing, heating, air conditioning, or sprinkler systems on the property, even when the original cause falls under the rodent exclusion.1Insurance Information Institute. HO 00 03 10 00 – Homeowners 3 – Special Form The insurer would pay for the water damage to floors, walls, and belongings, though not to repair the pipe the squirrel chewed through.
The Practical Line
The pattern is consistent. The policy will not pay for the thing the squirrel directly damaged, but it will pay for the covered peril that followed. If squirrels shredded your attic insulation, that is a denied claim. If squirrels shredded your attic insulation and a chewed wire then started a fire that burned through your ceiling, the fire damage is a real claim worth filing.
What You Will Pay Out of Pocket
Because the rodent exclusion leaves most squirrel damage on you, it helps to know the price range. Professional squirrel removal typically runs $300 to $600 for basic trapping and relocation. If the squirrels are in your attic, expect to pay $500 to $1,500, because the job involves trapping, cleanup, minor repairs, and sealing entry points. A comprehensive eviction plan with exclusion devices on all entry points, extended trap monitoring, and a warranty can reach $1,400 to $4,000.
Those numbers only cover getting the squirrels out. Repair costs come on top. Replacing contaminated attic insulation can run several dollars per square foot across a full attic, and rewiring a section of chewed cable requires a licensed electrician. If squirrels damaged ductwork, drywall, or roofing materials, each trade adds its own bill. Homeowners dealing with an established colony that went unnoticed for months can easily face total costs in the low thousands.
How Maintenance Affects Even the Ensuing Loss Claim
Even when ensuing loss coverage might apply, the insurer will look at whether you kept up with basic maintenance. Policies commonly exclude damage from neglect or failure to protect property from foreseeable risks. If squirrels entered through a rotted soffit you ignored for two years, the insurer has a stronger argument that you failed to maintain the property, which can complicate or sink a claim for the fire or water damage that followed.
Adjusters look for signs that should have prompted action: visible gaps in the roofline, damaged attic vents, scratching sounds in the walls, droppings in the attic, chewed materials near entry points. If those signs were present for months before a loss, an adjuster may argue the damage was foreseeable and preventable. Routine attic and roof inspections, along with records of any repairs or pest control services, give you something concrete to point to if a claim is ever questioned.
Your policy also requires you to take reasonable steps to stop the problem from getting worse once you know about it. The standard HO-3 “Reasonable Repairs” provision pays the reasonable cost of measures taken solely to protect covered property from further damage by a covered peril.1Insurance Information Institute. HO 00 03 10 00 – Homeowners 3 – Special Form If you hear squirrels in your attic and do nothing for six months until they chew through a wire and start a fire, the insurer can argue the fire damage was avoidable and reduce or deny the payout.
Reasonable steps include hiring a wildlife removal service, sealing entry points, removing nesting materials, and having an electrician inspect any wiring the squirrels may have reached. Document everything. Take photos before and after, save invoices, and keep written reports from any professionals. Many insurers expect you to report damage promptly after discovery, and delays give adjusters ammunition to argue the damage worsened because you waited.2National Association of Insurance Commissioners.

What To Do If Your Claim Is Denied
If your insurer denies a claim and you believe the ensuing loss exception applies, start with the denial letter. The insurer must identify the specific policy provisions it relied on. If the letter cites only the rodent exclusion without addressing whether the ensuing loss clause covers the fire or water damage that followed, the denial may be incomplete.
Most insurers have an internal appeals process. Submit a written appeal with supporting documentation: photos of the damage, contractor reports that distinguish the rodent damage from the ensuing fire or water damage, and evidence that you maintained the property and acted promptly. The goal is to make clear that you are claiming for a covered peril, not for the rodent damage itself.
If the internal appeal fails, you can file a complaint with your state’s department of insurance. These agencies oversee insurer conduct and can investigate whether a denial was handled properly. They cannot force an insurer to pay a claim, but a regulatory inquiry often prompts a second look. Contact information for your state’s department is available through the National Association of Insurance Commissioners.2National Association of Insurance Commissioners.

For larger dollar amounts, an attorney who handles insurance coverage disputes can change the outcome by evaluating whether the denial was consistent with the policy language and applicable regulations. Arbitration and mediation are available in many states as faster, cheaper alternatives to a lawsuit. Litigation is the final option, worth pursuing only when the claim is large enough to justify the expense.
