When buying or selling a home in North Carolina, few documents are as important yet as commonly misunderstood as the Wood-Destroying Insect Report (WDIR). This critical inspection can impact financing, negotiations, and closing timelines, yet many real estate transactions proceed with participants having only a vague understanding of what the report actually covers. At Neuse Termite and Pest Control, we've performed thousands of these inspections across the Triangle area, and we're sharing our expertise to help both buyers and sellers navigate this essential component of the real estate process.
What is a Wood-Destroying Insect Report (WDIR)?
A Wood-Destroying Insect Report (sometimes called a "termite inspection" or "clearance letter") is a standardized document that reports on the presence or absence of wood-destroying insects and evidence of their activity in a structure. In North Carolina, the official WDIR form is the NPMA-33, developed by the National Pest Management Association and adopted by state regulatory authorities.
What the Report Covers
The WDIR specifically addresses:
- Current visible evidence of wood-destroying insects, including:
- Termites (subterranean, drywood, and Formosan)
- Powder post beetles
- Old house borers
- Carpenter ants
- Carpenter bees
- Previous infestation evidence that indicates prior activity, even if no active infestation exists
- Conditions conducive to infestation, such as:
- Wood-to-soil contact
- Excessive moisture
- Improper ventilation
- Accessibility issues that prevent full inspection
- Previous treatments for wood-destroying insects (if evidence exists or records are available)
What the Report Does NOT Cover
Equally important is understanding what a WDIR does not address:
- Non-insect wood destroyers such as rot, fungus, or mold
- Damage assessment or repair estimates (the report notes evidence but doesn't quantify damage)
- Hidden or inaccessible areas that cannot be visually inspected
- Future infestations (the report is a snapshot of current conditions only)
- Insects that don't destroy wood such as spiders, cockroaches, or other general pests
The Legal Standing of a WDIR
In North Carolina, a WDIR is:
- Legally required for most mortgage transactions, including FHA, VA, and conventional loans
- Valid for 30 days from the inspection date
- Binding on the inspector who performs it
- Regulated by the North Carolina Department of Agriculture and must be performed by a licensed structural pest control operator
Why WDIRs Matter in Real Estate Transactions
Wood-destroying insect inspections play a crucial role in the real estate process for several important reasons:
For Buyers
A WDIR provides critical protection and information:
- Financial protection: Helps prevent purchasing a home with existing termite damage or active infestations
- Negotiation leverage: Identified issues can be addressed through repairs or price adjustments
- Future planning: Knowledge of previous treatments helps in planning ongoing protection
- Mortgage requirements: Most lenders require a "clear" WDIR before closing
- Peace of mind: Confirmation that the home is free from active wood-destroying insects
For Sellers
Proactive WDIR management offers several advantages:
- Transaction smoothing: Addressing issues before listing can prevent last-minute closing delays
- Pricing confidence: Knowing your home's condition allows appropriate pricing
- Disclosure protection: Proper documentation helps fulfill disclosure obligations
- Marketing advantage: A pre-listing "clear" WDIR can be a selling point
- Negotiation preparation: Advance knowledge of issues prevents surprise renegotiations
For Real Estate Professionals
WDIRs represent both obligations and opportunities:
- Client protection: Ensures clients' interests are protected through proper inspection
- Transaction facilitation: Proactive WDIR management prevents closing delays
- Professional liability: Recommending proper inspections helps fulfill fiduciary responsibilities
- Expert positioning: Knowledge of WDIR processes demonstrates professional expertise
- Problem solving: Understanding how to address findings helps overcome transaction obstacles
The WDIR Process: What to Expect
Understanding the inspection process helps all parties prepare appropriately:
Before the Inspection
Proper preparation ensures a thorough inspection:
- Scheduling: Typically arranged 1-2 weeks before closing, though sellers may opt for pre-listing inspections
- Access requirements: The inspector needs access to all areas, including:
- Crawl spaces
- Attics
- Basements
- Garages
- Interior rooms
- Exterior perimeters
- Preparation steps:
- Clear access to crawl space entrances
- Ensure attic access is unobstructed
- Remove stored items blocking foundation walls
- Provide keys or access codes if needed
- Secure pets during the inspection
During the Inspection
A professional WDIR inspection includes:
- Exterior examination:
- Foundation perimeter inspection
- Identification of wood-to-soil contact
- Assessment of grading and drainage
- Examination of exterior wood elements
- Crawl space inspection:
- Examination of floor joists and support beams
- Assessment of moisture levels and ventilation
- Checking for termite mud tubes and damaged wood
- Evaluation of vapor barriers and insulation condition
- Attic inspection:
- Examination of rafters and roof decking
- Looking for evidence of carpenter ants or bees
- Checking for proper ventilation
- Assessment of any accessible wood members
- Interior inspection:
- Examination of accessible structural elements
- Checking vulnerable areas like bathrooms and kitchens
- Assessment of visible wood components
- Looking for evidence of moisture issues
- Documentation:
- Detailed notes on any findings
- Photographs of evidence or issues
- Measurements of moisture levels where relevant
- Recording of any visible damage or activity
After the Inspection
Once completed, the process continues with:
- Report generation: The official NPMA-33 form is completed, typically within 1-2 business days
- Finding classification: Results fall into several categories:
- No visible evidence of wood-destroying insects (a "clear" report)
- Visible evidence of active infestation
- Visible evidence of previous infestation
- Visible evidence of previous treatment
- Conditions conducive to infestation
- Distribution: Copies go to the requesting party, usually the buyer's agent or mortgage company
- Treatment recommendations: If issues are found, treatment options are provided
- Clearance process: If treatment is required, a new WDIR is issued after completion
Understanding WDIR Findings and Next Steps
Different findings on a WDIR have different implications for the transaction:
No Visible Evidence (Clear Report)
The best-case scenario:
- Indicates no visible signs of current or previous wood-destroying insect activity
- Generally allows the transaction to proceed without pest-related contingencies
- May still note inaccessible areas that couldn't be inspected
- Does not guarantee future protection or absence of hidden damage
Active Infestation
When live wood-destroying insects are found:
- Typically requires treatment before closing
- May lead to negotiations regarding treatment costs
- Often triggers additional inspections to assess damage extent
- Usually requires a follow-up WDIR after treatment
- May impact closing timeline depending on treatment scheduling
Previous Infestation
Evidence of past (but not current) activity:
- May indicate successful previous treatment
- Often requires evaluation of any resulting damage
- Might prompt negotiations regarding repairs
- Should trigger discussions about preventative measures
- Generally doesn't prevent closing but may affect negotiations
Conditions Conducive to Infestation
When the inspector identifies risk factors:
- Commonly includes excessive moisture, wood-to-soil contact, or poor ventilation
- May require correction before closing, depending on severity
- Often becomes a negotiation point between buyer and seller
- Usually requires less urgent attention than active infestations
- Can typically be addressed without delaying closing
Common WDIR Issues and Solutions
Several situations frequently arise during WDIR inspections in North Carolina homes:
Moisture-Related Issues
Excessive moisture is a common finding:
- Problem: High moisture levels in crawl spaces or basements
- Cause: Poor drainage, inadequate ventilation, plumbing leaks, or missing vapor barriers
- Solution: Improve drainage, install vapor barriers, add ventilation, or consider crawl space encapsulation
- Negotiation tip: These improvements benefit the home's long-term condition and often benefit both parties
Wood-to-Soil Contact
Direct contact between wood and soil creates termite highways:
- Problem: Deck posts, door frames, or structural wood touching soil
- Cause: Improper construction, settling, or landscaping changes
- Solution: Create barriers between wood and soil, replace affected wood, or install proper supports
- Negotiation tip: Relatively inexpensive to fix but critical for preventing future infestations
Previous Treatment Evidence
Signs of past treatments often appear:
- Problem: Drill marks, termite bait stations, or documentation of previous treatment
- Cause: Prior infestations that were professionally addressed
- Solution: Verify treatment effectiveness and maintain ongoing protection
- Negotiation tip: Previous professional treatment is often positive, showing proactive care
Inaccessible Areas
Some areas may be impossible to inspect:
- Problem: Portions of the structure that cannot be visually inspected
- Cause: Design limitations, finished basements, or stored items blocking access
- Solution: Limited options – either create access or accept the limitation
- Negotiation tip: Common in many homes; reasonable parties typically acknowledge these limitations
Treatment Options When Issues Are Found
When wood-destroying insects are discovered, several treatment approaches may be recommended:
Liquid Termite Treatments
The most comprehensive solution for subterranean termites:
- Application method: Trenching and treating soil around foundations or drilling and injecting through slabs
- Effectiveness: Creates a continuous barrier preventing termite entry
- Protection period: Typically provides 5-10 years of protection
- Cost range: Moderate to high initial investment with long-term value
- Warranty options: Often includes repair warranties up to $1,000,000 with annual renewals
- Transaction impact: Usually can be completed within 1-2 days, minimally delaying closing
Localized Treatments
For isolated infestations:
- Application method: Targeted application to affected areas only
- Effectiveness: Addresses specific problems but not comprehensive protection
- Protection period: Variable depending on situation
- Cost range: Lower than whole-house treatments
- Warranty options: Limited or none
- Transaction impact: Minimal; can often be completed same-day
Wood Replacement
When structural damage has occurred:
- Application method: Removal and replacement of damaged wood
- Effectiveness: Addresses damage but must be combined with treatment
- Protection period: N/A (addresses existing damage only)
- Cost range: Varies widely depending on damage extent
- Warranty options: Typically covered under contractor guarantees
- Transaction impact: Can cause significant delays depending on scope
Preventative Programs
For homes without active infestations:
- Application method: Various approaches from monitoring to preventative treatments
- Effectiveness: Provides early detection and prevention
- Protection period: Ongoing with regular service
- Cost range: Low annual investment
- Warranty options: Various depending on program
- Transaction impact: None; can be implemented post-closing
Tips for Home Buyers
If you're purchasing a home in North Carolina, consider these WDIR recommendations:
Before the Inspection
- Request the inspection early in the due diligence period, not days before closing
- Attend the inspection if possible to learn about the home's condition firsthand
- Provide access to all areas of the home, including clearing items from crawl space entrances
- Share history of any known previous treatments or problems with the inspector
- Ask questions about specific concerns you have about the property
After Receiving the Report
- Read the entire report, not just the summary findings
- Note any limitations or inaccessible areas mentioned
- Understand treatment recommendations if issues are found
- Get cost estimates for any required treatments or repairs
- Consider long-term protection even if the report is "clear"
Negotiation Strategies
- Prioritize active infestations as critical items requiring attention before closing
- Consider requesting preventative treatment even with a clear report
- Evaluate repair costs separately from treatment costs
- Request transferable warranties for any treatments performed
- Factor ongoing protection costs into your homeownership budget
Tips for Home Sellers
If you're selling your home, proactive WDIR management can prevent complications:
Before Listing
- Consider a pre-listing inspection to identify and address issues early
- Correct conditions conducive to infestation, such as moisture problems
- Gather documentation of any previous treatments or warranties
- Complete obvious repairs like fixing gutters or improving crawl space ventilation
- Ensure proper access to all areas requiring inspection
During the Listing Period
- Disclose known issues honestly to prevent future disputes
- Maintain the property to prevent new problems from developing
- Keep crawl spaces and attics accessible for inspections
- Be prepared with treatment options if your home has a history of problems
- Consider offering a home warranty that includes termite coverage
Responding to WDIR Findings
- Address active infestations immediately rather than negotiating
- Get multiple quotes for any required treatments
- Offer repair credits rather than delaying closing for minor issues
- Transfer existing warranties to the new owner when possible
- Document all corrections made in response to the report

FAQs About Wood-Destroying Insect Reports
How much does a WDIR cost in North Carolina?
In the Triangle area, WDIR inspections vary depending on the home's size and complexity. The fee covers only the inspection and report; any required treatments would be additional. Many companies, including Neuse Termite and Pest Control, will credit the inspection fee toward treatment if issues are found and addressed through their company.
Who typically pays for the WDIR in a real estate transaction?
In North Carolina, the buyer typically pays for the WDIR as part of their due diligence process. However, this is negotiable, and in some cases, sellers may opt to obtain a pre-listing inspection. The cost of any required treatments or repairs is a separate negotiation point between buyers and sellers.
How long is a WDIR valid?
A WDIR is valid for 30 days from the inspection date. If closing is delayed beyond this period, lenders typically require a new inspection or at minimum a recertification from the original inspector confirming that conditions have not changed.
What happens if the WDIR finds active termites?
If active termites are found, most lenders will require treatment before closing. The parties will need to negotiate who pays for the treatment and any associated repairs. After treatment, a new "clear" WDIR must be issued before closing can proceed.
Are sellers required to fix all issues noted on a WDIR?
Not necessarily. Active infestations typically must be addressed before closing with most lenders, but conditions conducive to infestation (like moisture issues) are negotiable between the parties. The purchase contract often determines repair responsibilities.
Can I use any pest control company for a WDIR?
No. In North Carolina, WDIRs must be performed by companies and individuals licensed by the NC Department of Agriculture & Consumer Services Structural Pest Control Division. Always verify proper licensing before scheduling an inspection.
