Wood Infestation Issues in Real Estate

The National Pest Management Association reports that termites cause approximately $6.8 billion in property destruction each year in the United States, a number further complicated by the fact that most, if not all, of typical home insurance policies would not cover termite infections.

A seller’s property disclosure states wood-destroying organisms, since failing to disclose them creates legal liability. A wood infestation report discloses damage to the property caused by the wood-destroying organism.

What is a wood infestation report? Having an idea about what this report is provides information as to whether there are traces of a current or past termite attack in the property. It is an official document that is used to reveal the fact that a dwelling has been examined.

Buyers need clarity on what they’re looking for, how inspection reports are read in practice, and what changes when a seller fails to disclose what they know. Sellers also need to understand that the “as-is” wording in a contract doesn’t shield them completely from liability if they actively concealed a known, material defect. 

Both seller and buyer have to understand how wood-destroying organism findings play with mortgage financing. In veteran affairs (VA) and Federal Housing Administration (FHA) deals, an active infestation can stop a closing entirely. Pre

The Organisms That Generate Real Estate Liability

Four kinds of wood-destroying organisms tend to come up the most during real estate inspections and in court disputes.  

Subterranean termites are the most destructive and also the most litigated against. They make mud tubes straight out of soil toward the structure, they consume wood from the inside toward the outside, and they can rack up serious structural damage before you see any obvious surface clues. 

A mature colony, with several hundred thousand insects, can keep going for years. They can be in wall cavities, under floor joists, exterior porches and in subflooring, yet still show no visible signs in the living areas. Common indicators of termites include exit holes and the presence of a fine, sawdust-like material (frass) around the baseboards and other structural components.

Carpenter ants don’t really eat wood. What they do instead is excavate it and carve galleries for nesting. These insects tend to pick wood that’s already moisture-damaged or softened. Their presence usually means there’s some moisture issue in the property.

The powderpost beetle, just like most of the wood-boring beetles, deposits its eggs within the holes in the wood. The juveniles make long tunnels in the wood and, after several years, appear as adult beetles, forming small roundish or oval holes at the exit. These pests can hit hardwoods, and from there they may spread into structural members flooring, and furniture too.  

The group of wood-destroying organisms that cause dry rot, wet rot and other similar conditions are not insects. Instead, it is composed of fungi, which break down the cell structure of wood after it has been in contact with sustained moisture. 

It still needs moisture for dry rot to develop and spread. Fungus doesn’t have to stay wet to grow. Instead, they can be dormant while the wood is drying out and then comes back after it gets wet again. When your wood has dry rot, it causes the wood to turn brown and become dry and brittle with definite cube-shaped cracking as it spreads. Whereas a wet rod and other types of wood decay make the wood softer, lighter in color, and more fibrous in texture.

What the Wood-Destroying Insect Report Documents, and What It Does Not

The Wood Destroying Insect Report (WDIR) is completed using the NPMA-33 form for federally backed loans but the exact name and scope vary by state. For instance, Florida’s Wood Destroying Organism Report specifically leaves out carpenter ants and carpenter bees from its scope. Meanwhile, Mississippi’s Wood Destroying Insect Report includes both. The same report in two different states can certify two genuinely different things.  

A licensed pest control professional then does a visual inspection of accessible areas and writes down what they find in two categories, Section 1 and Section 2. Section 1 covers signs of active infestation or damage from wood-destroying insects that really require treatment or repair. 

Section 2 tackles scenarios that increase the tendency for re-infestation. Example situations include ground-to-wood contact, moisture leaks, bad airflow, etc. Its timeframe is around 90 days from the official inspection day. If closing gets delayed and it runs past that window, lenders that require a WDIR will need a reinspection. 

What the WDIR doesn’t cover is just as important. It’s a visual inspection of accessible areas only. It doesn’t inspect behind walls, inside enclosed soffits, or beneath vapor barriers. An inspector who finds no evidence of active infestation isn’t certifying the structure is free of organisms, only that no evidence was visible in accessible locations at the time of inspection. Buyers who read a clear report as a guarantee of a pest-free structure are misreading the document.

How Lender Requirements Work: VA, FHA, and Conventional Loans

Mortgage lenders have their own independent requirements that can affect whether a transaction closes, regardless of what the seller and buyer have agreed to.

VA loans require a wood-destroying insect inspection when the property sits in a moderate-to-heavy or very heavy infestation probability zone, as determined by the VA’s infestation probability map. If an active infestation or structural damage turns up, treatment and clearance must be completed before the VA will issue a Notice of Value and before the loan can close. Effective July 2025, the VA updated its local requirements by county, expanding the zones where inspections are routinely required. Reports must use the NPMA-33 form.

An FHA loan requires a pest inspection immediately if the appraiser spots visible damage or evidence of wood-destroying pests during the appraisal. That’s not the only trigger since some states and local jurisdictions require the inspection regardless of what the appraisal turns up. In areas where pest inspections are customary, lenders often require one as a standard practice.

Conventional loans don’t have uniform federal requirements, but individual lenders frequently require a WDIR as a condition of financing, and purchase contracts commonly include a termite inspection contingency giving the buyer the right to negotiate repairs or walk away based on findings.

Seller Disclosure Obligations and Liability for Nondisclosure

In the vast majority of states, sellers are legally required to disclose known material defects to prospective buyers. In every jurisdiction that has addressed the question, a wood infestation, whether current or historical, meets the definition of a material defect. That obligation doesn’t disappear when the property is listed as-is. A Statesville real estate litigation attorney says that disputes over property condition disclosures are among the most common sources of real estate litigation, right alongside boundary and title issues. A seller who leaves out known structural problems is a recurring reason buyers file claims.

An as-is clause kind of tells the buyer that the seller is not going to make repairs. This clause doesn’t allow the seller to hide known conditions or to play word games around them. A seller who knows about a current or even prior infestation, then doesn’t say so, can face possible liability for fraudulent concealment, negligent misrepresentation, or statutory violations under state disclosure laws. In that kind of scenario, buyers usually have a basis to pursue damages for repair costs and diminished property value, and in the more egregious situations, they may even push for rescission of the sale. 

The seller’s knowledge is the key issue in this situation. Buyers who discover an undisclosed infestation after closing should review the seller’s disclosure statement for what was reported, gather any pest control records or prior inspection reports the seller may have had, and consult a real estate attorney before the applicable statute of limitations on fraud or disclosure claims runs. Proving the seller’s prior knowledge is challenging but often documented in prior treatment records, insurance claims, or neighborhood pest control histories.

Negotiating After a Positive Inspection Finding

When a WDIR or pest inspection turns up active infestation or damage, the buyer has a few options depending on how the purchase contract is structured. The buyer can ask the seller to treat the infestation and repair structural damage before closing, along with documentation from the treating company. The buyer can opt to negotiate a price reduction or seller credit to offset treatment and repair costs. Another option is to simply walk away from the transaction and have earnest money returned if the inspection contingency permits. 

Sellers facing Section 1 findings on a VA or FHA transaction have less flexibility. Those findings must be resolved before the loan closes, regardless of the parties’ preferences. For standard deals, the parties have a bit more latitude and the result basically depends on the contract language and the back-and-forth negotiating posture.  

Wood infestation problems in residential property sit at the intersection of pest biology, disclosure rules, and mortgage underwriting requirements. Each layer operates independently, so if one layer encounters a problem, the entire transaction can slow down or go completely off track. 

Buyers usually guard themselves by scheduling a qualified inspection before they waive contingencies, reading the WDIR thoroughly enough to grasp what it includes and what it leaves out, and checking that the seller’s disclosure statement lines up with the property’s real history. 

Sellers guard themselves by saying what they know. Otherwise, they risk exposure to liability that can outlive the closing date. It’s important to have a real estate attorney familiar with disclosure duties in your state to help you regarding exact statutes involved. They can also assess whether a nondisclosure argument is valid and outline what remedies might exist if an infestation appears after the sale.
