Pest and Termite Findings on a Home Inspection Report — What Buyers Need to Know

Your home inspection and a pest inspection are different things

Standard home inspections cover the visible condition of the home's structure and systems. Your inspector may note signs of pest activity — mud tubes, damaged wood, frass (termite droppings), exit holes — but most home inspectors are not licensed pest inspectors.

A WDI report (wood-destroying insect inspection, sometimes called a termite inspection or pest clearance letter) is a separate evaluation conducted by a licensed pest professional. It specifically looks for evidence of termites, carpenter ants, carpenter bees, and wood-boring beetles.

Some states and loan types require a WDI report as part of the transaction. VA loans require one in most areas. FHA loans may require one depending on location. Conventional loans typically don't, but your lender or insurer may request one based on the home inspection findings.

If your home inspector flagged potential pest activity, a WDI report is the logical next step. The pest inspector can confirm what's there, whether it's active, and what treatment is needed.

Active infestation vs. evidence of past activity

This distinction drives every decision that follows.

Evidence of past treatment. You may see treatment stickers, drill holes along the foundation (from liquid termite treatment), or a notation that the home has a termite bond or warranty. Previous treatment with no current activity is common. Many homes in the Southeast, Gulf Coast, and Pacific regions have been treated at some point during their lifetime. On its own, prior treatment is not a red flag — it means someone identified and addressed the issue.

Active infestation. Live termites, fresh mud tubes, new frass, or wood that sounds hollow when tapped are signs of current activity. Active infestations need treatment, and the scope of any structural damage needs evaluation. This is a finding to take seriously, but it's not necessarily a deal breaker if the damage is limited and the treatment plan is clear.

Structural damage from past or current activity. Termite damage that has compromised floor joists, sill plates, support beams, or subfloor is the most significant category. The treatment may be straightforward, but the structural repair adds cost and complexity. A pest professional identifies the infestation; a contractor or structural specialist evaluates the repair.

Common pest findings and what they mean

Subterranean termites. The most common termite type in the U.S. They build mud tubes from the soil to the wood and can cause significant damage over time. Treatment typically involves liquid soil treatment around the foundation or a baiting system.

Drywood termites. More common in coastal and southern states. They live inside the wood rather than in the soil, and leave small piles of frass (pellet-shaped droppings). Treatment ranges from localized injection to whole-home fumigation (tenting) for widespread infestations.

Carpenter ants. They don't eat wood — they excavate it for nesting. The damage tends to be less extensive than termites, and treatment involves eliminating the colony and addressing moisture that attracted them. Carpenter ants are often associated with water-damaged wood.

Wood-boring beetles (powderpost beetles, old house borers). Small exit holes and fine sawdust indicate activity. These pests are more common in older homes with hardwood framing. Treatment depends on whether the infestation is active or historical — old exit holes in dry, sound wood may represent a past issue that resolved on its own.

Thinking about costs

Pest treatment and structural repair are two separate cost categories.

Treatment costs. A standard liquid soil treatment for subterranean termites typically runs $500 to $2,000 depending on the home's perimeter. Baiting systems cost less upfront but require ongoing monitoring. Drywood termite fumigation (tenting the entire home) can cost $1,200 to $3,500 or more based on the home's size. Localized treatments for carpenter ants or limited beetle activity may run a few hundred dollars.

Structural repair costs. If termites have damaged framing, the repair depends on what was affected. Sistering a few damaged floor joists might run $500 to $1,500. Replacing a sill plate can cost $1,000 to $5,000 depending on access and extent. Extensive structural damage involving multiple areas and difficult access can push costs higher. A contractor who works with pest-damaged structures can give you a real number.

Ongoing prevention. Many pest companies offer annual termite bonds or warranties that include monitoring and re-treatment if termites return. These typically cost $100 to $300 per year. If the home is in a termite-prone region, maintaining a bond is worth considering as part of your long-term homeownership costs.

These are rough ranges. Get specific quotes for your situation. More on thinking about repair costs.

Insurance and lending considerations

Termite damage is specifically excluded from most standard homeowner's insurance policies. Insurance covers sudden events — a burst pipe, a storm — not gradual damage from pests. This means the cost of treatment and repair falls on you as the buyer unless you negotiate it with the seller.

VA loans require a WDI report in most counties, and the loan may not close if there's active infestation or untreated damage. FHA loans have similar requirements in certain regions. Conventional loans are more flexible, but if pest damage raises structural concerns, the appraiser may flag it.

If your report includes pest findings that affect structural elements, check with your lender early. You need to know whether anything needs to be resolved before closing.

Negotiating pest and termite findings

Pest findings are common negotiation items, and sellers in termite-prone regions generally expect them.

Strong negotiating items: Active infestation requiring professional treatment, structural damage to joists, beams, or sill plates, any finding that affects the home's structural integrity or your ability to insure it.

Moderate negotiating items: Treatment installation (liquid treatment or bait system) with no structural damage, establishment of a termite bond or warranty that transfers to you at closing.

Typically not worth negotiating: Evidence of past treatment with no current activity, old beetle exit holes in sound wood, minor cosmetic damage with no structural concern.

For structural damage, a credit makes more sense than asking the seller to handle the repair. You'll control the contractor, the scope, and the quality. For treatment alone, having the seller handle it before closing (with documentation of the treatment and a transferable warranty) can work well. More on repairs vs. credit.

When to walk away

Most pest findings are manageable. A few situations warrant serious reconsideration.

If the structural damage is extensive — multiple compromised support members across different areas of the home — the repair costs may approach a level that changes the math on the purchase. If the seller is unwilling to negotiate on active pest issues, that tells you something about how they've maintained the property. If the home has a history of repeated infestations with ongoing structural deterioration, the underlying conditions (soil contact, moisture, construction type) may make the home a persistent target.

These are edge cases. For the majority of homes with pest findings, the combination of treatment and targeted structural repair resolves the issue. More on deal breakers.

What to do next

If your home inspection flagged pest activity, schedule a WDI inspection with a licensed pest professional. They'll confirm whether the activity is current or historical, identify the species, and recommend treatment if needed. If there's structural damage, get a contractor's assessment and quote for the repair.

Once you know the treatment cost and any repair scope, you'll have clear numbers to bring to your negotiation. If you're on a VA or FHA loan, check with your lender about any requirements that need to be met before closing, and coordinate the timeline with your contingency deadline.
