Termite damage and homeowners insurance: the insect exclusion, the hidden-collapse exception and what courts have required

Termite damage is not covered by a standard HO-3 homeowners policy: the ISO sample form lists "birds, vermin, rodents, or insects" among the causes of loss it does not insure. The one opening is narrow. If insect damage hidden in the framing, unknown to anyone in the household, makes part of the house abruptly fall down or cave in, Additional Coverage 8 for collapse can pay for that collapse.

Termites eat out of sight, which is why the exception exists and why it is so hard to use. The Environmental Protection Agency's consumer page on termites says most people "are not aware they have termites until they see a swarm or come across damage during construction," and that property owners spend over two billion dollars a year to treat them. By the time a joist gives way, the damage behind it is usually years old. The Texas Department of Insurance home insurance guide, last updated June 1, 2026, lists "Termites, insects, rats, or mice" under damage most policies don't cover. A homeowner whose floor has dropped is therefore asking two narrower questions: did the house actually collapse in the policy's sense, and was the insect damage hidden and unknown until it did?

Exclusion c.(6)(g) and Additional Coverage 8, in the form's own words

Coverage A for the dwelling and Coverage B for other structures in the HO-3 sample (ISO form HO 00 03 10 00, in the sample copy the Insurance Information Institute publishes) are written on an open-peril basis. The form says "We insure against risk of direct physical loss" to that property, then lists what it does not insure. Two entries in that list matter here. Item 2.b removes loss "Involving collapse, except as provided in E.8. Collapse." Item 2.c.(6) removes loss caused by a run of slow or internal causes, and its letter (g) reads, in full, "Birds, vermin, rodents, or insects." Termites are insects, so the cost of replacing wood they have eaten is outside Coverage A and B however large the bill. The very next letter, (h), removes "Animals owned or kept by an 'insured'," which puts a family dog's chewing in the same position; our guide to dog and cat damage under a homeowners policy sets out what that letter still leaves covered.

Additional Coverage 8 is where the exception lives. Its paragraph b insures "for direct physical loss to covered property involving collapse of a building or any part of a building if the collapse was caused by one or more of" six listed causes. The third is the one that matters for termites:

"(3) Insect or vermin damage that is hidden from view, unless the presence of such damage is known to an 'insured' prior to collapse;"

The second listed cause is decay hidden from view, on the same knowledge condition, which matters because termite damage and rot often travel together under a wet crawl space. What counts as a collapse is defined in paragraph a of the same clause, and our foundation and collapse guide sets out its four parts; the short version is that the building or part must abruptly fall down or cave in so that it cannot be used for its current purpose, and that sagging, cracking, leaning or separating while still standing does not qualify.

Two more paragraphs narrow the opening further. Paragraph c says loss to "an awning, fence, patio, deck, pavement, swimming pool, underground pipe, flue, drain, cesspool, septic tank, foundation, retaining wall, bulkhead, pier, wharf or dock" is not included under causes two to six, which include hidden insect damage, "unless the loss is a direct result of the collapse of a building or any part of a building." A deck that termites have hollowed out and that falls on its own is therefore outside the exception. Paragraph d says the coverage "does not increase the limit of liability that applies to the damaged covered property," so a collapse claim is paid inside the Coverage A limit and after the deductible, not on top of them.

One sentence after the exclusion list can help with what happens next. "Under 2.b. and c. above, any ensuing loss to property described in Coverages A and B not precluded by any other provision in this policy is covered." The eaten wood is never paid for under that sentence. But if a termite-weakened wall lets a supply line pull apart and water pours into the house, the water damage is a separate loss that may fall under the form's accidental discharge exception, which our burst pipe claim guide explains. Expect an adjuster to separate the two lines on the estimate.

Eleven termite situations and the clause behind each

The rows apply the October 2000 HO-3 sample's collapse and insect wording. Your policy may use different collapse wording, which the court cases further down show can change the result, and some insurers use their own forms entirely. Find the collapse paragraph in your own policy before relying on any row.

The table has one covered row for damage to the house, and it depends on three facts the homeowner has to establish: an abrupt fall or cave-in, insect damage that was hidden, and no prior knowledge. The water row deserves a note of its own. Exclusion A in the sample applies to listed causes "regardless of any other cause or event contributing concurrently or in any sequence to the loss," and its water damage paragraph includes water below the surface of the ground that seeps or leaks through a foundation. In the New Jersey case below, the court cited a similar water exclusion alongside the insect and rot exclusions. For the moisture side of these claims, our mold coverage guide works through the rot and fungus wording.

Hidden from view, and known to an insured

The exception turns on two phrases the sample does not define. "Hidden from view" suggests damage inside walls, under subfloors or behind finishes, where no one would see it in ordinary use of the house. Mud tubes running up an exposed foundation wall, or a joist visibly crumbling in an open crawl space, are harder to describe as hidden. Neither phrase is defined in the form, so each claim is argued on its facts and on the law of the state.

"Known to an 'insured' prior to collapse" is the phrase most likely to cost a homeowner the claim, and the paper trail of owning a house in termite country is what supplies the knowledge. Three kinds of documents can do it. A wood-destroying insect report from the purchase, which a lender may have required, can note old damage or a prior treatment. A termite company's annual inspection report can record conditions; in the Alabama case below, one report listed "Excessive Moisture in Crawl" with the status "Customer Responsibility." And a seller's disclosure may describe past infestation. None of these automatically means the insured knew of the damage that later caused a collapse, but each is the kind of document an insurer will ask for and read.

The practical answer is not to avoid inspections, since an inspection is what finds termites before they take a floor down. It is to close the loop on whatever a report finds. If a report notes damage, get it repaired, keep the invoice and photos showing the repaired area, and file them with the report. A later collapse in a different part of the house, or in the same area after a documented repair, is then easier to separate from the damage that was known. If you are buying, our guide to insuring a house you are buying lists the other documents to collect before closing.

Who has to prove what, in the Texas case that spelled it out

Claims over termite collapse are decided by burdens of proof as much as by facts. The federal district court in Houston set out the Texas allocation in its June 24, 2020 opinion in the Stewart case: the insured "bears the initial burden of showing that there is coverage," the insurer has the burden of proving "the applicability of any exclusions in the policy," and if the insurer proves an exclusion applies, "the burden shifts back to the insured to show that the claim is within an exception to the exclusion." The court tied the insurer's part to Texas Insurance Code section 554.002, which treats an exclusion as an avoidance or affirmative defense. Other states use similar but not identical rules, so treat the table as the Texas version and ask about your own state if a claim is contested.

The policy adds its own duties, and they decide what evidence survives. Section I Condition B of the sample requires the insured to "give prompt notice," to protect the property from further damage by making "reasonable and necessary repairs" while keeping "an accurate record of repair expenses," to show the damaged property as often as the insurer reasonably requires, and to send a signed, sworn proof of loss "within 60 days after our request." Condition G bars a lawsuit unless it is started "within two years after the date of loss." Many states change these deadlines by law; our claim deadlines by state guide lists them.

Both court records below show why the order of events matters. In the Texas case, the insurer's engineer reported that the homeowner had already "removed and replaced the soft subfloor decking and reinforced the floor joist" before the inspection. In the New Jersey case, the homeowner could not say when the gap in her floor had formed, and shoring was installed within four days of discovery. Shoring a failing floor is the reasonable repair the policy asks for and may be needed for safety. The evidence to capture first is simple: dated photos and video of the floor, the framing and the damage from several angles, the pieces of wood that come out, and a written note of when and how the failure happened, including any sound. That record is the homeowner's proof of an abrupt event, which is step one in the table.

Six court rulings, dated, from courts' own records

Each row comes from an opinion or order filed by the court and published on govinfo.gov, the federal government's official publication site. Cases are named by the homeowner and docket number; this site does not name insurers, and the pest control company in two rows is described rather than named. Four rows are insurance disputes and two are disputes over termite company contracts, which is where much of the money in a termite loss is actually argued over. A federal court hearing a case like these applies the law of the state where the house stands.

The insurance rows line up on one point: neither homeowner in the collapse cases showed a building part that had actually fallen or caved in, and both lost. Sagging floors, a dropped floor with a gap at the wall, and broken joists under a floor that still bore weight all failed the definition. The two contract rows show the other half of the picture. With the policy closed to the damage itself, the money question moves to whatever termite contract is on the house, and those disputes turn on the exact promise the contract makes.

All six rows are federal cases, and state appellate courts have their own decisions on collapse and insect damage. If a ruling from your state's courts matters to your claim, read the opinion on that court's own site, or ask a lawyer licensed there.

Retreat-only, repair guarantee and the transfer clause

Termite contracts, often called bonds, come in two broad kinds, and the two court cases above show both. The 1972 contract in the Alabama case was retreat-only. Its guaranty promised additional treatment "at no extra cost" if termites returned, and then said the company's "liability under this agreement is limited to retreat only and in no way, implied or otherwise, is responsible for damages or repairs to the structure or contents." The initial treatment cost $213, and renewals were $30 a year, figures from 1972 that were not adjusted for inflation. The contract also said the company was not responsible for repairing visible damage that existed when the contract was signed.

The 1991 contract in the Louisiana case carried a repair guarantee. The first owner paid $1,230 for the initial treatment and obtained a guarantee that the company would re-treat and repair new damage from subterranean termites while that owner held the house and paid renewals. Two limits decided the case. The guarantee "did not cover damage from Formosan termites," the more aggressive species that later infested the house, and it said it was "not transferrable after one year from the original treatment date." The later owners said they were assured at closing that they were getting a full repair guarantee; the court noted that those assurances were not made by anyone from the company.

Two points carry across to insurance. First, the homeowners policy pays nothing for either kind of contract: the fee is upkeep, and no insuring clause in the sample pays for maintenance. Second, the inspection reports a contract produces are records of what was known. Fix what they flag, get the fix documented, and keep both together.

Inspection and contract costs against a repair the policy will not pay

No federal or state agency we checked publishes a benchmark price for a termite inspection, a treatment or an annual contract. The official figures that do exist are rules and fees, and the court records add a few real prices with their years attached.

Because there is no official current price, the comparison below uses assumed round numbers to show how the arithmetic works. They are not averages and not quotes. Replace each one with the written quotes you get locally, since prices vary with the region, the species, the size and construction of the house and the treatment method. The repair figure is set at $7,000 to match the excluded estimate in the 2010 Louisiana record.

The totals check out as follows: $1,200 plus $7,000 is $8,200; $1,200 plus $2,250 plus $7,000 is $10,450; $1,500 plus $3,600 is $5,100. Under these assumptions, a retreat-only contract costs more than having none in both outcomes, because it pays for treatment but not for repair. What it buys is annual inspection, which can catch termites before damage reaches $7,000; if the inspections are thorough, the year-6 repair in that column should be smaller. The repair guarantee costs $5,100 whether or not termites come, and comes out ahead when new damage would cost more than its extra fees over the other two columns. The homeowners row is zero in every column, because none of these losses is a collapse.

A homeowner deciding whether any of this is worth it should weigh the local risk first. The EPA page names native subterranean, drywood and invasive Formosan termites as the types found in the United States, and a contract that does not cover the species in your area is worth little. If a large termite repair coincides with a storm claim, read our guide on whether to file a small claim before splitting the work, because the termite lines will not count toward the deductible.

When a floor drops or a ceiling comes down

1. Get people out and call for help if anything is still moving. A failing floor or ceiling is a safety problem before it is a claim.
2. Record the scene before anyone shores it. Dated photos and video of the room, the failed area from below if it can be reached safely, and the damaged wood. Write down the date, the time and what was heard or seen.
3. Make the protective repair, and keep what comes out. Shoring and temporary supports are the reasonable repairs the sample requires. Keep the removed wood and the invoices.
4. Give prompt notice and ask for the collapse wording in writing. Ask the insurer which collapse clause applies, and whether your form says "collapse" or "entire collapse." The Stewart rulings show that one word changes the test.
5. Gather the termite paperwork. Purchase inspection reports, termite contracts, annual inspection reports and repair invoices. Read them for what they say was known, and when.
6. Get your own engineer if the insurer's report decides cause. The cause and the question of whether the event was abrupt decide the claim, and both are matters of expert opinion.
7. Watch the clock. The sample allows two years after the date of loss to sue, subject to state law. If the claim is denied, our claim denial appeal guide lays out the steps, and the claim filing guide covers the paperwork.

Termite damage that never reaches a collapse belongs to the house's upkeep, the same as a worn roof. The policy's place in the story is narrow, and knowing exactly where it starts saves a homeowner from paying for a claim that cannot succeed, or from giving up on one that can.
