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.


Structural fumigation legally requires specialized certification, which our lead fumigators carry and maintain.
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.
Our tenting equipment and gas detection tools meet state fumigation compliance requirements at every stage.
The entire structure is sealed under tarpaulin and treated with fumigant gas that penetrates every wall void and framing member.
We recommend fumigation specifically when inspection shows damage in locations that localized injection treatment can't reach.
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.
A licensed fumigator inspects the structure and confirms whether tenting is necessary versus a more localized alternative.
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.
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.
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.
