Drywood Termite Specialists — Spot Treatment to Full Fumigation
Drywood termites infest attic framing, furniture, door frames, and hardwood flooring without any soil contact. Louisiana's warm, humid climate makes them a persistent statewide threat. We match the method to the infestation — localized spot treatment when appropriate, whole-structure fumigation when required.
Drywood termite treatment addresses a fundamentally different pest than the Formosan subterranean termite. Where subterranean termites live underground and require soil contact, drywood termites colonize wood directly — no soil needed, no mud tubes, no moisture dependency. They infest attic rafters, wall studs, door and window frames, hardwood flooring, and even furniture, establishing multiple small colonies throughout a single structure simultaneously.
Louisiana drywood termite species — including the Western Drywood Termite (Incisitermes minor) and Southeastern Drywood Termite (Incisitermes snyderi) — establish small colonies of 2,500–4,800 mature workers that consume wood across the grain, creating smooth-sided galleries quite different from the mud-filled galleries of subterranean termites. A single structure can harbor dozens of independent drywood colonies in different locations simultaneously.
The treatment decision for drywood termites pivots on a single question: is the infestation localized and accessible, or has it spread throughout the structure? This determination should always rest on a thorough termite inspection by a licensed Louisiana specialist — not assumed based on the location of visible frass or surface damage alone.
Localized Spot Treatment: When activity is contained to an accessible area — a window frame, exposed rafter, or piece of furniture — termiticide is injected directly into infested wood through drilled access points.
Targeted Heat Treatment: For infestations in a contained area, heat raises the temperature above 120°F throughout infested wood for a sustained period. Heat penetrates uniformly, reaching colonies that injected termiticide cannot easily access. A non-chemical option suitable for sensitive environments.
Foam and Void Injection: For infestations inside wall voids or structural cavities that cannot be accessed by drilling, expanding foam formulated with termiticide fills the void and contacts the colony.
Whole-Structure Fumigation: When infestation has spread through multiple areas simultaneously, whole-structure fumigation is the most complete treatment. See our fumigation services page for full details.
Treatment cost depends primarily on whether localized spot treatment or whole-structure fumigation is warranted. See our full termite treatment cost guide for broader context.
| Treatment Type | Typical Cost Range | Best For |
|---|---|---|
| Localized Spot Treatment | $250 – $800 | Contained, accessible infestations |
| Targeted Heat Treatment | $400 – $1,200 | Localized; non-chemical preference |
| Foam Void Injection | $200 – $600 | Colonies in wall voids or hollow members |
| Whole-Structure Fumigation | $1,200 – $4,500 | Widespread or multi-area infestations |
| Post-Treatment Re-Inspection | $50 – $150 | Confirming spot treatment effectiveness |
Drywood termite colonies grow slowly but multiply — catching them while localized means spot treatment, not fumigation. Call now for a same-day assessment statewide.
