Drywood termites in finished furniture and attic wood demand targeted post construction treatments that differ from subterranean approaches.

For spot infestations start with a careful inspection to locate galleries by tapping and listening for hollow sounds and by looking for tiny fecal pellets that resemble coarse sawdust; once located use a probe to verify activity then inject a labeled topical insecticide into the gallery at multiple entry points working slowly so the product disperses through the tunnel system. For isolated furniture items consider local heat treatment by raising the internal temperature of the piece to at least one hundred twenty degrees Fahrenheit for a sustained period of two hours, using calibrated heaters or a professional heat unit and monitoring with thermocouples to avoid damage to finishes or veneers. When galleries are concentrated in structural members and spread is suspected evaluate whole structure fumigation as the only reliable option to reach every gallery, arranging displacement of people and pets and following strict aeration and reentry protocols; always coordinate with a licensed fumigator who will provide written clearance and reentry instructions. Replace or professionally treat heavily infested furnishings when integrity or appearance is compromised; for replacement consider kiln dried or heat treated wood to reduce reinfestation risk. For attic infestations combine targeted topical injections with exclusion work such as sealing vents and repairing roof leaks because moisture and entry points invite return infestations. Keep clear records of treatment dates, products used, concentrations, and treated locations so future inspections can identify persistent activity or retreatment needs.

Common problems include missing active galleries that lead to incomplete control because pellets and hollow sound checks were overlooked, so solution is to perform methodical grid inspections and use a flashlight and thin probes to verify every suspect area. A second issue is treating without addressing conducive conditions like roof leaks, poor ventilation, and attic clutter which invites reinfestation, so solution is to remediate moisture sources, add baffles or vents to improve airflow, and remove or isolate stored items from attic rafters. A third frequent mistake is attempting heat treatment or injection without accounting for sensitive finishes and electronics, which can cause warping or damage, so solution is to either remove sensitive items for separate treatment or hire specialists who use controlled temperature ramps and protective shielding for electronics and finishes.
