Drywood termites in California structures often go unnoticed until frass pellets appear below kick-out holes or an escrow inspection flags active galleries. When colonies occupy multiple members across attics, wall voids, or roof decks, spot treatments and local fumigation no longer reach every active area, making whole-structure tenting the practical next step. The process requires complete gas containment for the required exposure period, after which aeration must reduce concentrations to safe re-entry levels.
Preparation failures cause most delays and callbacks. Occupants must remove all food, medicines, and pet items that cannot be sealed in special bags; plants and outdoor furniture must be moved away from the foundation; and interior items that absorb gas, such as mattresses and certain electronics, require specific handling. In Tehachapi’s older cabins with dirt crawl spaces and multiple additions, technicians spend extra time sealing gaps around plumbing penetrations and roof transitions before the tarps go on.

Once the structure is tented and the fumigant introduced, the team monitors concentrations and weather conditions that can affect hold time. After the label-required exposure, fans and exhaust systems run for hours while readings confirm clearance. Homeowners receive written re-entry instructions and must not reoccupy until the final clearance stamp is issued; any remaining pellets or tubes are left for the owner to monitor post-treatment.
Technician insight
In Tehachapi, the thing that catches most people out with Termite Fumigation and Tenting is the way high desert winds and temperature swings loosen tarp seals on older cabins that have settled on dirt crawl spaces; we spend extra time on roof transitions and plumbing penetrations because a single gap can force a repeat job.
Foothill Cabin With Widespread Drywood Activity
A vacant Tehachapi cabin showed frass in multiple attic bays and wall voids during a pre-sale inspection. Localized treatments had already failed twice. We completed full preparation, sealed the structure, performed the fumigation, and issued clearance after aeration; the escrow closed once the report was updated.

How it works
- 1
Detailed Inspection
Technician maps all visible drywood activity and confirms that localized options are insufficient before recommending tenting.
- 2
Preparation Walkthrough
Owner receives a written checklist of items to remove and areas to clear; crew returns to verify compliance on treatment day.
- 3
Tenting and Fumigation
Structure is sealed, fumigant introduced, and held for the required exposure period while weather and concentration are monitored.
- 4
Aeration and Clearance
Tarps removed, interior aerated, and multiple readings taken until levels allow safe re-entry and the clearance document is provided.
