Pest Inspections When Buying a Home: What to Know

Buying a home is stressful enough without pest questions adding to it. Here's what this inspection actually covers and how it typically fits into a home purchase — with the caveat that specific rules vary by state and loan type, so this is general information, not legal or real estate advice.

What does a home-buying pest inspection actually check?

This inspection — often called a Wood-Destroying Insect (WDI) or Wood-Destroying Organism (WDO) report — focuses specifically on pests that damage a home's structure, not general household bugs like ants in the kitchen. The inspector checks for:

• Termites (subterranean and drywood) — active activity, mud tubes, and past damage
• Carpenter ants — nesting activity in wood, particularly in areas with moisture
• Wood-boring beetles — small holes and powdery frass in structural wood
• Wood decay/fungus — conducive conditions like moisture intrusion that attract wood-destroying pests

This is separate from a general home inspection, which covers the roof, systems, and overall condition — though the two are sometimes scheduled around the same time. It's also different from a routine pest control visit; see what to expect during a pest inspection for how a standard residential inspection compares.

One thing worth being blunt about: a general home inspector is not a termite inspector. Wood-destroying insect work is its own specialty, and not every pest control company does it either. In our analysis of 18,941 calls from homeowners to pest control companies, 10.6% of people calling about termites reached a company that doesn't handle termite work at all — compared with 3.8% of cockroach callers, since general bug work is available nearly everywhere. When you're on a closing timeline, confirm up front that whoever you hire actually performs termite and wood-destroying insect reports for real estate transactions.

Is a pest inspection required to buy a house?

It depends on your loan type, state, and sometimes the property itself. Some loan programs and lenders require a clear termite or wood-destroying-insect report before closing, and this is more common in regions with higher termite activity. Requirements vary by loan type, lender, and state, so ask your lender early what they'll need. Conventional loans generally don't mandate a pest inspection, but many buyers order one anyway as part of due diligence.

Your real estate agent can tell you what's customary in your local market, but the lender's answer is the one that governs your closing — so get it in writing rather than assuming either way.

How much it matters also depends on where you're buying. Across 7,799 calls where we could see how things turned out, termite calls ended with an appointment being booked 38.8% of the time in the desert Southwest, 33.1% in mixed-humid areas, and 32.8% across the Gulf South and Florida — but only 17.6% in the cold northern tier. That's the widest regional gap of any pest we measured. If you're buying in the South or Southwest, a termite inspection is worth ordering whether or not your loan demands one. In colder northern markets termites are a smaller factor, though wood-boring beetles, carpenter ants, and moisture damage still make the report useful.

Who pays for the pest inspection when buying a home?

This varies by region, local custom, and negotiation — there's no single national rule. In some markets it's customary for the seller to pay for a clear termite letter as part of closing costs; in others, the buyer orders and pays for it as part of their own due diligence. It's a negotiable point, so raise it early with your agent.

Whoever orders it, this is a negotiable line item in most purchase contracts. It's worth raising directly with your real estate agent early in the process so it's built into the offer rather than a surprise near closing.

What does the inspection report actually mean for the sale?

The report will typically come back as one of a few outcomes:

• No evidence found — no visible activity or damage. This doesn't guarantee a home will never have termites, but it's the cleanest outcome for a sale.
• Evidence of past damage, no current activity — often still workable for the sale, sometimes with a request for repair of damaged wood.
• Active infestation found — this typically triggers negotiation: the seller treats and clears it before closing, a credit is issued to the buyer, or in some cases the buyer walks away.

The report itself is a factual document — it doesn't approve or block a sale on its own. What happens next depends on your purchase contract terms and negotiation between buyer and seller, which is where your real estate agent and, if needed, a real estate attorney come in.

What should you do if the report finds a problem?

First, don't panic — termite damage found during a home purchase is common and very often resolvable. Typical next steps:

1. Get a treatment estimate. A licensed pest company can quote what treatment and repair would cost, giving you a concrete number to negotiate with.
2. Decide what you're asking for. Common asks include seller-paid treatment before closing, a credit toward repairs, or an extended inspection period to assess damage extent.
3. Loop in your agent and, if warranted, an attorney. Especially for larger damage findings, get advice specific to your contract and state before proceeding.
4. Get a re-inspection after treatment. If the seller treats before closing, request documentation and a clearance inspection so you're not taking their word for it.

This is general guidance — for anything transaction-specific, always consult your real estate agent, your inspector, and, where appropriate, a real estate attorney, since contract terms and state law vary.

When to call a professional

If you're under contract on a home and a pest inspection turns up active termites or significant past damage, get a licensed pest control company out for a full assessment and treatment quote before your inspection contingency period closes. Timing matters here — most purchase contracts have a limited window to negotiate repairs, so don't wait until the last few days to act.

What if you're selling and worried about the inspection?

If you know or suspect there's termite activity on a home you're selling, it's usually smarter to get ahead of it — a pre-listing inspection and any needed treatment can prevent a surprise that derails a deal later. Buyers are far more likely to walk away from an unexpected finding during their own inspection than from a documented, already-treated issue disclosed upfront.
