What Is Termite Tenting and When Is It Needed?
Termite tenting — formally called structural fumigation — is the process of enclosing an entire structure under a sealed tent and introducing Vikane (sulfuryl fluoride) gas at lethal concentrations throughout the building. The gas penetrates every piece of wood in the structure, eliminating all drywood termites regardless of location — including colonies deep inside roof trusses, wall framing, and structural timbers that are physically inaccessible to spot treatments.
Tenting is the most thorough and definitive treatment available for drywood termite infestations. It is the recommended approach when:
- Multiple drywood termite colonies are present in different areas of the structure
- Colonies are in inaccessible locations (roof trusses, enclosed wall cavities)
- A WDO inspection for real estate reveals active infestation requiring clearance
- Previous spot treatments have failed to resolve the infestation
- The scale of infestation visible externally (frass piles, swarmer evidence) indicates widespread activity
In Miami-Dade County, drywood termites are endemic and active year-round due to the subtropical climate. Miami has one of the highest drywood termite pressure levels in the United States. Homes that go more than 5–7 years without a termite inspection in Miami-Dade are at significant risk for infestations that have progressed to the point where tenting becomes necessary.
The Miami Termite Tenting Process
Our FDACS licensed inspector evaluates your home for drywood termite activity, identifies all infestation points, and assesses whether tenting or spot treatment is the appropriate recommendation for your situation.
We conduct a detailed walkthrough with you covering all preparation requirements: food and medication bagging, plant and pet removal, gas service coordination, and neighbor notification if applicable.
Our licensed fumigation crew installs the tent — heavy tarpaulins sealed at ground level — covering the entire structure. Warning agents and secondary locks are placed on all entry points per Florida fumigation regulations.
Vikane (sulfuryl fluoride) is introduced at the calculated lethal dose based on the cubic footage of your structure and current outdoor temperatures. Concentration monitoring devices are placed inside the structure.
The tent is removed and the structure is aerated. A certified fumigation professional uses clearance devices (Fumiscope or Drager tubes) to verify the gas concentration has dropped below the EPA re-entry level of 1 ppm before issuing clearance for re-occupancy.
We recommend borate wood treatment (TimBor or Bora-Care) on exposed wood in attic spaces after fumigation to provide ongoing residual protection against future drywood termite colonization.
