A structural fumigation involves sealing the entire building under tent and monitoring gas concentration precisely — this isn't a service to hire without a state-licensed fumigator directing every stage. Because the gas penetrates solid wood rather than just surface cracks, fumigation reaches colonies living deep inside framing that no injection or spray treatment could ever access.
We inspect the extent of damage first, since fumigation is only recommended when localized treatment genuinely won't reach every colony.


Every fumigation job is directed by a technician holding a specific state fumigation license, separate from standard pest licensing.
We coordinate tenting, gas exposure time, and aeration clearance into a clear timeline so you know exactly when you can re-enter.
Pricing is quoted based on structure size and tenting complexity, given in full before any tarps go up.
We use sulfuryl fluoride gas with certified monitoring equipment to confirm safe concentration and clearance levels.
Tenting reaches areas spot treatment physically cannot — inside solid wood framing, not just surface-level cracks.
When drywood termite colonies are spread across multiple areas of a structure, fumigation eliminates all of them in one treatment.
We provide a full prep checklist covering food removal, plant relocation, and pet arrangements before tenting day.
After gas exposure, the structure is aerated and tested with certified equipment before we clear it safe for re-entry.
We manage the added complexity of fumigating occupied multi-unit buildings with proper notice and scheduling.
You'll receive full documentation of the fumigation, including gas application records and clearance certification.

The structure is tented, treated, aerated, and clearance-tested before we certify it safe for re-entry.
Knowing exactly when we could move back in made planning around the fumigation so much less stressful.
The clearance documentation they provided was exactly what our insurance company needed on file.
Appreciated that they didn't just upsell us into tenting when a smaller treatment would have worked.
Buying an older home with visible drywood damage in three separate rooms, fumigation ended up being the only option that made sense, and the crew explained every stage of tenting clearly.

We'll give you a specific timeline based on your structure size once the assessment is complete.
Food items, medications, and plants typically need to leave, along with pets — we provide a full checklist ahead of time.
The gas dissipates completely during aeration, and we don't clear the structure until testing confirms it.
Compliance paperwork covering the entire process is available whenever you need it on file.
Yes, we coordinate larger tenting projects including tenant notification and scheduling for multi-unit structures.
