Wood-Destroying Insect Inspection in Frederick
A Wood-Destroying Insect (WDI) inspection documents evidence of termites, carpenter ants, carpenter bees, and wood-boring beetles in a property — using the NPMA-33 form required by most lenders for real estate transactions in Maryland.
What the WDI Inspection Covers in Frederick Properties
The NPMA-33 form is the industry-standard report for wood-destroying insect inspections. It requires the inspector to check for five categories: evidence of wood-destroying insects, damage from wood-destroying insects, conditions conducive to infestation, previous chemical treatment, and previous treatment for repairs. Each section must be completed by a licensed pest control operator in Maryland. Our inspectors are licensed and experienced with the specific requirements for VA, FHA, and conventional loan transactions in Frederick County.
Eastern subterranean termites are the most common WDI finding in Frederick homes. But carpenter ants — especially in moisture-damaged wood near bathrooms, rooflines, or decks — are also a common finding in older Frederick homes. Carpenter bees cause cosmetic and structural damage to exposed wood trim, fascia, and decking. Old house borers and other wood-boring beetles may be present in structural timber of pre-1960 homes, and their exit holes can be mistaken for termite damage by untrained eyes.
We inspect all accessible areas systematically and complete the NPMA-33 accurately, noting any areas that could not be inspected due to access limitations. If conducive conditions are observed — wood-to-soil contact, moisture damage, excessive mulch against the foundation — these are documented even when active insects are not present.

Common Questions About WDI Inspections
Does the WDI inspection cover mold or moisture damage?
The NPMA-33 form is limited to wood-destroying insects, but inspectors note conditions conducive to infestation — which includes moisture damage. Significant moisture problems are flagged because they attract termites and carpenter ants and can mask or accelerate wood damage from insect activity.
What is the difference between a WDI report and a general pest inspection?
A WDI report on the NPMA-33 form is specific to wood-destroying insects and meets lender requirements. A general pest inspection covers a broader range of household pests — rodents, cockroaches, ants in general, spiders — but does not satisfy lender WDI requirements for real estate transactions.
How long is a WDI report valid for a real estate transaction?
Most lenders require the WDI report to be dated within 30–90 days of closing, depending on the loan type. VA guidelines typically require the report within 90 days. Check with your lender for the specific requirement on your loan.
