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.
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.
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.
Larger commercial buildings and multi-unit structures get coordinated tenting plans accounting for tenant notification and timing.
You'll receive full documentation of the fumigation, including gas application records and clearance certification.

Call +1-866-315-0243 to schedule a fumigation suitability assessment for your St. Charles property.
A licensed fumigator inspects the structure and confirms whether tenting is necessary versus a more localized alternative.
We provide a full written quote and a prep checklist covering what needs to leave the structure before tenting day.
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.
As a property manager for a multi-unit building, coordinating tenant notification for fumigation seemed daunting, but Nex Pest Control handled the scheduling and paperwork.
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.

Nex Pest Control dispatches licensed fumigators throughout St. Charles and nearby communities for structural tenting projects of any size. We handle single-family homes, multi-unit buildings, and commercial structures across St. Charles, each with its own tenting and coordination plan.

Inspection findings, not a sales pitch, determine whether tenting is the right call for your structure.
Typically a few days, covering gas application, exposure time, and aeration before clearance testing confirms it's safe to return.
Most furniture and belongings can stay sealed inside; it's primarily consumables and living things that need to be removed.
The gas dissipates completely during aeration, and we don't clear the structure until testing confirms it.
Yes, we provide full fumigation and clearance documentation on request for insurance claims or property transactions.
Yes, we coordinate larger tenting projects including tenant notification and scheduling for multi-unit structures.
