Drywood Termite Fumigation Process
Every step from inspection to re-entry clearance.
Drywood Inspection
Full structural inspection mapping all active colonies and assessing infestation extent — confirming whether fumigation or spot treatment is the appropriate method.
Preparation Guidance
Written checklist covering food storage, medication removal, plants, and pets. Most preparation is completed the day before tenting.
Tent Installation and Treatment
The structure is sealed under a tent and treated with a licensed penetrating fumigant at the concentration calculated for the structure volume.
Aeration Period
The tent is opened after the treatment exposure period. The fumigant dissipates completely — leaving no residue on surfaces, fabrics, or food-contact materials.
Gas Clearance Testing
Gas levels are measured throughout the structure with certified monitoring equipment. Re-entry is approved only when readings fall below the established safe threshold.
Written Warranty
The treated structure carries a written warranty. If drywood termites return to treated areas during the warranty period, re-treatment is provided at no charge.
Drywood Fumigation Step by Step
From inspection to re-entry — a documented process at every stage.
- 1
Inspection and Confirmation
We map all frass deposits and colony locations, confirming that the infestation is in locations that require fumigation rather than accessible spot treatment.
- 2
Preparation
You receive a written checklist. Most preparation is completed in one afternoon. Accommodations are arranged for 24-48 hours.
- 3
Fumigation
The structure is tented, sealed, and treated with a licensed penetrating fumigant. Every wood void, wall cavity, and framing member is reached.
- 4
Clearance and Re-Entry
Post-aeration gas testing confirms safe levels throughout the structure. Written re-entry clearance is provided before family and pets return.

Case Study
Fumigation Ends Recurring Drywood Infestation in a Montrose Bungalow
The Problem
A Montrose homeowner had received three rounds of spot treatment over four years from a different company. Frass kept appearing in new locations — a window frame, then a hallway closet, then attic trim. Each treatment addressed the visible colony but the infestation continued to spread.
Our Solution
Resolve performed a full structural inspection and found active colonies in seven confirmed locations, including three inside wall cavities where spot injection was not feasible. Tent fumigation was performed as the only method capable of reaching all active colonies simultaneously.
The Outcome
Frass production stopped completely after fumigation. The 6-month and 1-year follow-up inspections found no active drywood activity anywhere in the structure. The homeowner enrolled in annual monitoring. The recurring cycle that had continued for four years ended with a single treatment.
Drywood Termite Fumigation FAQs
How do I know if my drywood infestation requires fumigation?
If frass is appearing in multiple rooms, or if previous spot treatments have not stopped activity, the infestation may have spread to inaccessible locations where spot injection cannot reach. A thorough structural inspection confirms whether fumigation is necessary.
How long does drywood fumigation take?
Most drywood tent fumigation treatments require 24-48 hours from tent installation to re-entry clearance. You will need alternative accommodations for the full treatment and aeration period.
What happens to furniture and belongings during fumigation?
The fumigant leaves no residue on furniture, fabrics, or surfaces after the aeration period. No cleaning or preparation of interior household items is required after re-entry clearance is confirmed.
Will fumigation prevent future drywood termite infestations?
Fumigation eliminates all current drywood colonies in the structure. It provides no ongoing barrier — new colonies can be introduced through infested furniture or flying swarmers. Annual inspection after fumigation catches new introductions before they establish in inaccessible framing.
Why did drywood termites keep coming back after spot treatment?
Spot treatment eliminates accessible colonies but cannot reach those inside wall cavities or structural framing. If the infestation had already spread to inaccessible locations before the spot treatment, frass from untreated colonies continues appearing — even after the treated colonies are gone.
