Your closing date is on the calendar and the moving truck is booked. Then the inspection report arrives with a line like “evidence of subterranean termite activity in the crawlspace” or “rodent droppings observed in attic.” It’s stressful, but it rarely ends a deal. Pests found before closing on a house come up often in real estate, and there’s a well-worn process for handling them. This guide covers how the inspection works, how serious different findings are, what buyers and sellers can do, and how to get treatment done before closing day.
When pests are found before closing, the buyer and seller usually negotiate one of four outcomes. The seller treats the problem and provides proof, the seller gives a credit at closing, the price is lowered, or the buyer cancels under an inspection contingency. Most deals close once a licensed pest control company treats the issue and documents the work.
The right choice depends on three things: the type of pest, whether there’s structural damage, and how much time is left before closing. A mouse problem in the garage is a very different conversation from termite damage in the floor joists.
A standard home inspector will note obvious signs such as droppings, mud tubes, chewed wiring, or nests. But a general inspection is not a pest inspection. For wood-destroying insects, buyers usually need a separate WDI (wood-destroying insect) inspection, also called a termite inspection. A licensed pest professional performs it, and in many states the results are recorded on the standard NPMA-33 form.
The inspector checks foundations, crawlspaces, basements, attics, window frames, and wood touching soil. They look for live insects, damage, and conditions that invite pests, like moisture and wood-to-ground contact.
The buyer typically pays for the pest inspection before home sale, though this can be negotiated. Some loans make it mandatory. VA loans, for example, often require a WDI inspection in states with higher termite risk. FHA and conventional lenders may require one if the appraiser notes signs of pest damage. Ask your lender early so the inspection doesn’t get squeezed into the last week.
Not every finding carries the same weight. Here’s how the most common discoveries usually play out.
| Finding | Typical Concern | Usually Fixable Before Closing? |
| Active termites | Ongoing structural damage | Treatment yes; repairs may take longer |
| Old termite damage, no activity | Past damage, need proof of prior treatment | Often, with records |
| Rodents (mice, rats) | Contamination, chewed wiring, insulation damage | Usually, with trapping and exclusion |
| Carpenter ants | Wood damage, often tied to moisture | Usually |
| Bed bugs or cockroaches | Health and comfort | Needs multiple visits |
Termites cause the most worry, and for good reason. They can work inside walls and floors for years without being seen. If a termite or rodent is found during home inspection, the first question is whether the activity is active or old. Active termites need treatment right away. Old damage with no live activity may only need documentation of a past treatment plus a structural check.
If there’s visible damage to support beams, sill plates, or joists, bring in a contractor or structural engineer to assess the wood. Treatment kills the insects. It doesn’t repair what they already ate.
Mice and rats are common, especially in older homes and in fall and winter. The concern goes beyond the animals themselves. Rodents chew electrical wiring, which is a fire risk, and they contaminate attic insulation with urine and droppings. A good rodent job includes trapping, sealing entry points (exclusion), and sometimes cleaning or replacing insulation.
What Buyers Should Do Next
If pests turn up in your inspection, stay calm and follow these steps:
A closing credit gives you control over who does the work and how. A seller-arranged treatment is faster and puts the hassle on them. Either can work well if the paperwork is solid.
Sellers generally have two paths. Arranging seller pest treatment before closing shows good faith and removes the issue from the table, which often keeps the buyer from asking for more. A credit is simpler but may cost more if the buyer pads the estimate.
In our experience, treating before closing tends to be the smoother route when time allows. Buyers feel more confident moving in, and lenders are satisfied when they see a clean report.
Paperwork Buyers Expect
Keep everything in writing:
Also check your state’s seller disclosure rules. Many states require sellers to disclose known pest problems and past treatments. Being upfront protects you from disputes after the sale.
Timing is where most deals get stuck. Some treatments are quick, and others take weeks to confirm results.
If your closing is days away, call a company that handles fast scheduling and knows real estate paperwork. Booking pest treatment on a tight closing timeline can keep your closing date intact instead of forcing an extension. Tell the technician upfront that you need a completion letter for a sale, so the right documentation is ready when your agent asks for it.
If treatment truly can’t finish in time, the parties can agree to hold funds in escrow until the work is done. Your real estate agent or closing attorney can set that up.
Yes, if the contract includes an inspection contingency and the buyer acts before its deadline. Without a contingency, backing out may mean losing the earnest money.
It’s negotiable. Sellers often pay for treatment of active infestations, especially when a lender requires a clear WDI report. Some buyers accept a credit and handle it themselves.
Not usually. If there’s no active infestation and the seller can show proof of past treatment, most buyers and lenders will move forward. Serious structural damage may still need repair.
A typical WDI inspection takes about one to two hours, depending on home size and access to crawlspaces and attics. The written report usually follows within a day or two.
Not always. It depends on your loan type, your state, and your lender. Even when it isn’t required, it’s a smart, low-cost step before one of the biggest purchases of your life.
Pests found before closing on a house are a problem to solve, not a reason to panic. Get a clear diagnosis, negotiate a fair fix, insist on written proof, and move quickly so your contingency and closing dates stay on track. Buyers get a healthier home, and sellers get a cleaner sale.
