Do I Need a Pest Inspection Before Closing on a House?
Often, yes — many lenders require a wood-destroying-insect (WDI) inspection, documented on the NPMA-33 form, before closing, and even when it's optional it's smart protection against inheriting hidden termite or carpenter-ant damage. In Central New York, carpenter ants and moisture-related wood damage are the most common findings, more so than termites.
What a WDI inspection covers
A wood-destroying-insect inspection checks the accessible areas of a home for evidence of termites, carpenter ants, powderpost beetles, and other wood-destroying insects, and documents the findings on the industry-standard NPMA-33 form that lenders and buyers rely on. It's focused specifically on insect activity and damage, separate from a general home inspection.
Why it's worth it in CNY
Buying a home is a major investment, and wood-destroying-insect damage is often hidden until it's serious. A local inspection also brings useful context: in Central New York, an inspector who knows the region will pay close attention to carpenter ants and moisture damage, which are more common here than termites.
How we help
We provide WDI inspections with clear NPMA-33 documentation on your closing timeline, and because we also treat these pests, we can handle any needed work directly to keep your closing on track. We're glad to coordinate with your agent or lender.
What the inspection is and is not
A wood-destroying insect inspection is usually documented on the industry-standard NPMA-33 form, and it is a focused inspection for evidence of wood-destroying insects — carpenter ants, termites, powderpost beetles, old house borers — in the visible and accessible areas of the structure. Lenders frequently require it, particularly on certain loan types.
It is important to understand the boundaries. It covers what can be seen and reached, so finished basements, insulated walls, and inaccessible crawlspaces limit what any inspector can report. It is also not a general home inspection and not a structural engineering assessment — it addresses insects and the conditions that favor them, not the building overall.
Timing it within the transaction
Schedule it early enough that findings can still affect the deal. An inspection that comes back with active carpenter ant activity, or with conditions conducive to it, is information you want while there is still time to negotiate a repair, a credit, or a walk-away — not the week of closing.
In this region, the finding most likely to come up is carpenter ant activity or moisture conditions favorable to it, rather than termites. That distinction is worth knowing before you read the report, because seeing wood-destroying insect on a form tends to be alarming out of proportion to what is usually behind it here.
Common questions
What does a WDI inspection actually cover?
Evidence of wood-destroying insects in the visible and accessible areas of the structure, documented on the NPMA-33 form. It does not cover concealed areas behind finished walls or inaccessible crawlspaces, and it is not a general home inspection.
Is a finding on the report a deal-breaker?
Usually not by itself. In this region the most common findings are carpenter ant activity or conditions conducive to it — moisture, wood-to-soil contact, poor drainage — which are addressable. Getting the inspection early enough that you can still negotiate is what matters most.
