Pest problems affect real estate at every stage — from the inspection that kills the deal, to the disclosure that scares buyers, to the repair costs that reduce your net proceeds. Understanding which pest issues matter most to buyers (and their lenders) helps sellers prioritize fixes before listing.
Active termite infestation with structural damage: The #1 pest deal-breaker. Mortgage lenders in most states require a clear WDI (Wood-Destroying Insect) report before approving loans. Active termites or visible termite damage triggers repair requirements that can delay or kill the transaction. Sellers in termite-prone areas should get a pre-listing termite inspection and address issues before the buyer's inspector finds them.
Visible rodent infestation: Droppings in the attic, gnawed wiring, and displaced insulation in the crawl space signal deferred maintenance that makes buyers question what else was neglected. Mouse and rat evidence should be cleaned up and entry points sealed before listing.
Active carpenter ant or wood-boring beetle damage: Both appear on WDI/WDO reports alongside termites. Active infestations require treatment and may require structural repair documentation.
Moisture conditions: Wet crawl spaces, condensation in attics, and moisture problems signal future pest risk to informed buyers (and their inspectors). A $500 dehumidifier and vapor barrier installation prevents $5,000+ in negotiated price reductions.
Evidence of past infestations without documentation: Old termite damage without treatment records makes buyers assume the worst. Keep all pest treatment receipts, inspection reports, and warranty documentation — organized documentation reassures buyers that issues were properly addressed.
Active termite bond/warranty (transferable): A transferable termite warranty is a selling point in termite-prone markets. It demonstrates proactive maintenance and provides the buyer with immediate protection. Some bonds require a transfer fee ($50–100) and a re-inspection.
Recent whole-home pest treatment with documentation: A pre-listing pest treatment with a professional receipt shows buyers the home was actively maintained. Include it in your seller's disclosure package.
Sealed and pest-proofed home: Homes with visible exclusion work — door sweeps, sealed penetrations, screened vents — signal attention to detail that differentiates your listing.
