Annual Termite Inspection
Purpose
Define the annual termite inspection performed on residential properties under contract or on real-estate transactions. Termite damage costs U.S. homeowners billion annually; the inspection's job is finding evidence early - before structural damage becomes a repair. The visible signs (mud tubes, frass, swarmers) point to colonies hidden behind framing.
Scope
Applies to:
- Residential single-family + multi-family homes under termite contract
- Real-estate transaction inspections (WDI / WDO reports - separate documentation requirements)
- Pre-purchase inspections requested by buyer
Excludes commercial structures (specialty inspector + scope), and active termite remediation jobs (those are treatment, not inspection).
Responsibilities
- Dispatcher confirms access to crawlspace + attic + garage at booking
- Lead inspector (licensed termite inspector OR pest applicator with WDI endorsement) runs the inspection
- Customer receives a written report + photos within 5 business days
Procedure
- Customer briefing. "60 - 90 minute inspection. I'll look at the entire perimeter exterior, the foundation interior (basement or crawl), the attic, and any wood-to-soil contact. Some areas may need flashlight + mirror access."
- Exterior perimeter walk.
- Look for mud tubes on foundation walls (subterranean termites)
- Wood-to-soil contact (mulch above slab, wood siding touching ground)
- Conducive moisture (sprinklers spraying foundation, downspout dumping into bedded area)
- Cellulose debris near foundation (mulch, wood scraps)
- Foundation interior (basement or crawlspace):
- Inspect every joist + sill plate
- Probe suspect wood with a screwdriver - soft / hollow = damage
- Look at perimeter walls + columns for mud tubes
- Check the moisture barrier (vapor barrier in crawlspace) for tears
- Garage (often the most-overlooked entry point):
- Wall plates + studs at corners
- Wood door frames + thresholds
- Stairs into the home from garage (frequent entry point)
- Attic (where accessible):
- Soffit + eave wood for moisture damage + termite activity
- Wood-to-roof flashing junctions
- Interior finished spaces:
- Window + door frames (look for blistered paint or sawdust = drywood termites in southern regions)
- Floor sag or bounce
- Tap baseboards for hollow sound
- Document with photos.
- Every mud tube
- Every probe-test soft wood
- Every conducive condition
- Write the report. Categorize findings:
- Active infestation - visible live termites or fresh mud tubes
- Previous infestation - old damage, no current activity
- Conducive conditions - no termites but conditions favor establishment
- Treatment recommendations - bait stations, liquid barrier, or specific corrective actions
Acceptance Criteria
- Exterior perimeter walked + photographed
- Foundation interior inspected (basement OR crawl, depending on home)
- Attic inspected (where accessible)
- Garage inspected
- Written report with photos delivered to customer within 5 business days
- Active infestation OR conducive conditions clearly documented + recommendations quoted
A WDI (Wood-Destroying Insect) report for a real-estate transaction is a LEGAL document. Missing visible damage exposes you to lawsuit liability when the buyer discovers it post-close. Take your time on WDI inspections; photograph everything; document every accessible AND inaccessible area separately. If a major area is inaccessible (slab homes with no crawlspace), state explicitly in the report.
