If you're a real estate agent, you already know that deals can fall apart fast when pest issues surface at closing. A termite report, a rodent problem, or a wood-destroying insect finding can derail a transaction, trigger lender requirements, and send buyers running. The good news is that a proactive pre-sale pest inspection is one of the simplest ways to protect your listing, your client, and your commission.
Here's what every realtor needs to know.
Why Pest Inspections Matter in Real Estate Transactions
Pest inspections aren't just a courtesy -- in many cases they're required. VA loans mandate termite inspections in any county rated "moderate to heavy" on the VA's termite zone map, which covers a large portion of the country. FHA loans require a full pest inspection if an appraiser spots any signs of wood-destroying insects during the appraisal. Conventional loans leave it to the lender's discretion, but most will flag obvious pest issues.
Beyond lender requirements, undisclosed pest damage can create serious liability for sellers and their agents. Getting ahead of it before listing is simply smart practice.
What a Pre-Sale Pest Inspection Covers
A licensed pest inspector evaluates the entire property for active infestations, past activity, and structural damage caused by pests. Key areas include:
Foundation and crawl spaces -- termite mud tubes, moisture damage, subterranean termite activity
Wooden structural elements -- beams, joists, decking, window frames
Exterior walls and roofline -- carpenter bees, wood beetles, powderpost beetles
Basements and attics -- rodent droppings, nests, gnawed wiring, entry points
Interior walls and flooring -- soft spots, staining, and signs of hidden activity
The inspector issues a formal report, often using the NPMA-33 form, detailing findings, whether activity is active or inactive, and recommended treatments. That active vs. inactive distinction matters: not every finding requires treatment, and sometimes it is simply negotiated into the sale price.
The Most Common Pests That Derail Real Estate Deals
Termites are the biggest concern for most transactions. Subterranean termites alone cause billions of dollars in structural damage annually in the U.S., and many sellers have no idea they have them until an inspector finds mud tubes in the crawl space.
Other deal-breakers include:
Carpenter ants -- often misidentified as termites, but similarly destructive to wood
Powderpost beetles and wood-boring beetles -- common in older homes, often found in hardwood floors and structural timbers
Rodents -- mice and rats can compromise insulation, wiring, and HVAC systems
Bed bugs -- increasingly common in multi-unit and investment properties
When Should a Seller Get a Pest Inspection?
Before listing -- not after an offer comes in. Scheduling the inspection early gives sellers time to treat any issues, obtain a clearance letter, and present a clean report to buyers upfront. This builds buyer confidence, reduces inspection contingency negotiations, and can meaningfully speed up time to close.
As a rule of thumb, recommend a pre-listing pest inspection to your seller clients if:
The home is in a warm or humid climate (the South, Southeast, and coastal areas are especially termite-prone)
The property is more than 10 years old
There is any visible wood damage, moisture intrusion, or prior pest treatment history
The buyer is using a VA or FHA loan
What Happens If Pests Are Found
Finding pests doesn't automatically kill a deal. A seller who discovers and treats a termite problem before listing is in a far stronger position than one who gets blindsided during the buyer's inspection period. Options typically include:
Treatment and re-inspection -- the seller pays for treatment, obtains a clearance letter, and the sale proceeds cleanly
Price negotiation -- the cost of treatment is factored into the sale price or closing credits
As-is disclosure -- the seller discloses the finding and adjusts expectations accordingly
Buyers are far more likely to accept a known, documented, treated issue than one that surfaces as a surprise during due diligence.

A Note on Licensing and Verification
Always confirm that any pest inspector or exterminator you refer holds a current state-issued pest control license and carries general liability insurance. Licensing requirements vary by state, but a reputable company will have no hesitation providing proof. Never refer a client to an unlicensed operator -- the liability exposure isn't worth it.
