Importance of a Pest Inspection Before Buying a House: The WDO Report Explained (2026)

Updated October 2026. A buyer’s guide to the pest or wood-destroying organism (WDO) inspection: what it covers, what the report must say in Florida and Texas, and how to use it before closing. Statutes and rules read October 29, 2026.

A pest inspection before buying tells you whether termites or other wood-destroying organisms are in the house, have been treated, or left damage. Book it inside your inspection period. In Florida, as of October 2026, a licensed company doing one for a sale must use the state form and list 8 required items, including areas it couldn’t reach.

Why do you need a pest inspection before buying a house?

Termites and other wood-destroying insects work quietly. They can live inside framing for years before anyone sees a sign. A general home inspector may point out mud tubes or damaged trim, but a licensed pest inspector is trained to look for them, knows where they hide in your area, and writes a report your lender and the seller will take seriously.

First-time homeowners often learn about pests the hard way, after closing. The inspection moves that discovery to a moment when you still have choices. If the report finds something, you can ask for treatment, a repair, a credit or, if your contract allows, walk away.

In termite-heavy states, the inspection is routine. Maryland experts note that termites are a serious risk to wooden structures, which is why buyers there often bring in a termite exterminator before closing.

What does a WDO inspection report include?

Florida spells it out. Under statute 482.226, when a licensee inspects for wood-destroying organisms for a real estate transaction, and either charges a fee or is asked for a written report, the report goes on a form set by the state. It must include:

1. The licensee’s name.
2. The date of the inspection.
3. The address inspected.
4. Visible, accessible areas not inspected, and why.
5. Areas that were inaccessible.
6. Visible evidence of previous treatment or infestation.
7. Which organisms are present and any visible damage.
8. A statement that a notice of inspection was posted on the property, and where.

The report must also say the inspector has no financial interest in the property or the deal. If the company treats anything during the visit, the report names the organism, the pesticide and the terms. The licensee keeps a copy for at least three years.

Texas works the same way with its own form. Under 4 Texas Administrative Code 7.176, every report on termites or other wood-destroying insects tied to a real estate transaction must use the form prescribed by the Texas Department of Agriculture. It can’t be altered, though photos and graphs can be attached. A lender such as the Department of Veterans Affairs may require its own form too, as a supplement.

One phrase matters a lot. Florida’s statute says the report isn’t a promise that no organisms or damage exist unless it says so. It covers what was visible and accessible. Pay close attention to the “areas not inspected” section. A finished basement, a stored-up garage or a sealed crawl space can hide a lot.

When should you schedule a pest inspection?

As soon as your offer is accepted. Your contract gives you a set number of days to inspect, and the pest report should land well before that window closes, so there’s time to read it and negotiate.

• Book the pest inspection the same week as the general home inspection.
• Ask the seller to clear access to the attic, crawl space and garage walls.
• Ask whether the company also checks for conditions that invite termites, like wood touching soil or moisture against the foundation.
• Read the report the day it arrives, starting with the areas not inspected.

If the house has a history, ask the seller for past treatment records and any transferable termite bond or service contract. Annual property checks like this are part of what careful owners do anyway, so a seller who kept them is a good sign.

What should you do if the inspection finds termites?

Don’t panic. Get facts. A finding of past infestation with a treatment record is common in warm states. Live activity or structural damage is a bigger conversation.

Hiring residential pest control experts for a second look helps when the report is unclear or the damage could be structural. Pests other than termites, like rodents, also show up in reports and can point to entry gaps worth fixing.

How does the pest report fit into closing?

If the seller agrees to treat or repair, get it in writing in a contract amendment and ask for the paid invoice before closing. A credit shows up on the settlement statement, subject to your lender’s approval. The title company handles the money.
