What Drives Termite Fumigation Cost in Houston
Termite fumigation pricing in Houston is based on measurable factors rather than arbitrary flat rates. The primary driver is structure volume — the cubic footage of space that must be treated determines how much fumigant is needed and how long the process takes. A single-story 1,500-square-foot bungalow and a two-story 3,000-square-foot home require significantly different fumigant volumes to reach an effective concentration throughout every wood void.
The second factor is structural complexity. Homes with attached garages, detached structures, or unusual attic configurations require additional labor and setup time for proper tent sealing. Structure type and access constraints affect how long tent installation takes and how the fumigant calculation is applied.
The third factor — and the one most homeowners miss — is treatment method. Tent fumigation is the comprehensive option, but spot treatment by wood injection is significantly less expensive and equally effective for localized, accessible drywood infestations. Resolve recommends spot treatment whenever it genuinely solves the problem. The inspection determines which method is actually necessary.
How Fumigation Cost Is Calculated
Accurate pricing starts with measurement — no verbal estimates that change after the job begins.
- 1
Inspection and Measurement
We inspect the structure, confirm drywood termite activity, and measure structure volume for an accurate fumigation calculation.
- 2
Treatment Determination
If the infestation warrants fumigation, we calculate the required fumigant volume. If spot treatment is sufficient, we quote that instead — at a lower cost.

Written Quote
A written itemized quote is provided before any work is scheduled. No verbal ballparks, no post-job additions.
- 4
Inspection Credit
The inspection fee is credited toward the cost of treatment when you proceed with Resolve.
Why Fumigation Costs More Than Spot Treatment — and When the Difference Is Worth It
Tent fumigation costs more than spot treatment because it is a more involved process: tent installation, fumigant introduction at precise concentrations calculated for structure volume, a 24-48 hour aeration period, and post-aeration gas clearance testing before re-entry is approved. Every step requires licensed personnel and certified monitoring equipment. The cost reflects genuine labor, product, and compliance overhead.
Spot treatment is appropriate for localized infestations in accessible wood members — window frames, door trim, and exposed rafters — where the colony can be reached directly. In these situations, fumigation is not just more expensive but unnecessary. Resolve does not recommend tent fumigation when spot treatment will genuinely resolve the problem.
The critical distinction is infestation extent. Drywood termite colonies that have spread into multiple inaccessible areas — behind drywall, throughout attic framing, or in multiple wall sections — cannot be effectively treated by spot injection alone. In those cases, fumigation eliminates the problem completely in one treatment. Repeated partial spot treatments on a widespread infestation often cost more in total than a single fumigation would have.

What Affects Your Fumigation Quote
Six factors that determine the cost of termite fumigation in Houston.
Structure Volume
Fumigation is priced by cubic footage, not just square footage. Taller structures with higher ceilings require more fumigant to reach effective concentrations throughout every void.
Property Layout
Attached garages, detached structures, wraparound porches, or multiple rooflines add tent setup complexity and are factored into the quote.
Infestation Extent
Widespread infestations covering multiple locations require the same whole-structure approach — fumigation dose is calculated per structure volume, not per colony count.
Structure Age and Type
Older construction with complex framing, limited attic access, or non-standard rooflines may require additional setup time, which affects the overall quote.
Spot vs Tent Decision
If the inspection confirms the infestation is accessible and localized, spot treatment is quoted instead — at a meaningfully lower cost than full fumigation.
Written Documentation
