Pest Inspection (Wood-Destroying Insects)
This is commonly called a “pest inspection.” The scope is a targeted visual inspection for wood-destroying insect activity and conditions that can lead to infestation.
Often requested during real estate transactions; some lenders require a standardized report (NPMA-33).
What is a pest inspection?
A pest inspection (also called a WDO/WDI inspection) is a specialized assessment for insects that can damage wood structures—commonly termites, carpenter ants, carpenter bees, and wood-boring beetles.
This is a visual, non-invasive inspection of readily accessible areas of the property at the time of inspection. The goal is to identify visible evidence of activity or damage, and conditions conducive to infestation, so you can address issues early—especially during a real estate purchase.
What I inspect (accessible areas)
The inspection typically includes accessible areas where evidence is most likely to be observed:
-
Exterior perimeter and visible wood components (sills, trim, decks/porches where accessible)
-
Basement and/or crawlspace (when entry is possible)
-
Garage (as applicable)
-
Attic access areas (when accessible)
-
Interior areas with conditions suggesting risk (as applicable)
What I’m looking for
Visible signs consistent with active or past wood-destroying insect activity
Wood damage patterns that may warrant further evaluation
Conducive conditions (moisture conditions, wood-to-soil contact, debris/cellulose storage, etc.)
Reporting (NPMA-33 when required)
Findings are documented in a standardized pest/WDI report format. If your lender or transaction requires it, the NPMA-33 form may be used.
Important: A pest inspection/WDI report is not a warranty. Hidden activity or damage may exist in concealed or inaccessible areas.
Limitations
❌ Visual inspection only; no destructive testing or treatment
❌ Inaccessible areas may be limited by storage, finishes, insulation, low crawlspace clearance, or safety conditions
❌ Evidence may be present behind walls, under insulation, or within concealed framing even when not visible
When to book a pest inspection
-
Your lender, buyer, or agent requests a “pest inspection” or “termite letter”
-
You want a targeted assessment for wood-destroying insects (not a general household pest service)
-
You’ve had moisture issues, previous pest history, or wood-to-soil contact concerns
How to prepare
-
Ensure access to crawlspace and attic entries
-
Clear stored items away from foundation walls where possible
-
Provide access to garages and exterior wood areas as applicable
FAQ
Is this the same as general pest control?
No. This “pest inspection” is specifically focused on wood-destroying insects and related conditions. Treatment is typically performed by a pest control company.
Is this included with a home inspection?
This is an add-on service to a home inspection or can be booked separately. Price may vary. You can see our pricing section here.
Does this guarantee there are no termites/carpenter ants?
No. It’s based on visible evidence in accessible areas at the time of inspection.
