When drywood termite damage is spread across multiple wall sections or floors, spot treatment can't reach every colony — tent fumigation with sulfuryl fluoride is what clears the entire structure at once. 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.
You'll see one written quote covering tenting, gas application, aeration, and clearance testing.
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.
Our team walks you through exactly what needs to leave the structure and what can safely stay sealed inside.
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.

Tell dispatch about the extent of damage found so a licensed fumigator can assess whether tenting is the right call.
Our fumigation lead arrives to walk the property and explain the process before any commitment is made.
Assessment includes a clear timeline for tenting, gas exposure, aeration, and when you can safely return.
Guarantee coverage means any surviving drywood activity after fumigation is addressed at no additional charge.
Our drywood termite damage was spread across two floors and spot treatment just wasn't going to cut it. The fumigation team walked us through every step of the tenting process.
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.
The prep checklist they sent ahead of time made packing up the kitchen and moving out for a few days far less chaotic than we expected.
