“David inspected our Midtown home and found drywood termites in the attic framing — not subterranean as I assumed. He explained why a liquid barrier would not work for drywood colonies in the attic and what fumigation would involve. He managed all the neighbor notification and utility prep. The whole process was much smoother than I expected.”
Houston Termite Fumigation
Termite Fumigation in Houston, TX
Drywood termite colonies in Houston attic framing and window frames cannot be reached by liquid soil barriers — the colonies live inside the wood, not in the soil. Fumigation is the most thorough treatment for whole-structure drywood infestations. Resolve coordinates licensed structural fumigation for Houston homes, including neighbor notification, utility disconnection logistics, and the two-to-three day process from tent setup to re-entry clearance.
- Fumigation is the only treatment proven to reach drywood termites throughout an entire structure
- Neighbor coordination and utility preparation handled as part of the service
- Resolve performs the inspection and species confirmation before recommending fumigation
- Alternative: spot treatment with termiticide or heat for localized drywood colonies — fumigation is not always necessary
When Fumigation Is the Right Choice for Houston Termites
Not every termite problem needs a tent — but when it does, thorough preparation makes the difference.
- Drywood termites live inside wood members — fumigant gas penetrates the full structure and reaches colonies inaccessible to liquid or bait treatments
- Inspection confirms drywood species before fumigation is recommended — subterranean termites require a different treatment entirely
- Whole-structure coverage — fumigation reaches the attic, wall voids, floor framing, and every wood member simultaneously
- Resolve handles neighbor notification and utility preparation logistics for Houston residents
- Spot treatment or heat treatment assessed as an alternative when the infestation is localized
- Post-fumigation inspection confirms clearance before re-entry — no shortcuts on safety
Houston Homeowners on Fumigation and Drywood Termite Control
Licensed fumigation Species confirmation first Full logistics coordination
“We found frass pellets in the master bedroom — classic drywood termite sign. Two companies immediately quoted a tent without inspecting where exactly the colony was. David found it was a single localized colony in the window frame and recommended spot treatment instead of full fumigation. Honest assessment saved us thousands.”
“Our Museum District home needed full fumigation — drywood colonies in multiple attic sections. David coordinated everything including the timing with our neighbors and the utility company. We were out for three days and came back to a cleared certificate. No drama, very professional.”
Fumigation and Drywood Termite Services Resolve Provides
From species confirmation through post-fumigation clearance — every step managed.
Drywood Termite Inspection
David inspects for drywood termite frass pellets, galleries in wood members, and visible emergence holes in attic framing, window sills, door frames, and hardwood furniture. Confirmation of drywood species — and the extent of infestation — determines whether fumigation is the appropriate treatment.
Structural Fumigation Coordination
Resolve coordinates licensed structural fumigation for Houston homes — tent setup, sulfuryl fluoride gas application, and the two-to-three day process from tenting through aeration and re-entry clearance certificate. Licensed for the full fumigation process in Texas.
Neighbor and Utility Notification
Houston fumigation requires advance notification to neighboring properties and disconnection of gas service for the duration of the treatment. Resolve handles the notification logistics and coordinates the utility scheduling as part of the service.
Spot Treatment Alternative
When drywood termite activity is localized to a single area — a window frame, a specific attic section, or a piece of furniture — spot treatment with a termiticide injection or local heat application may eliminate the colony without full structural fumigation.
Post-Fumigation Clearance
Gas concentration is measured before re-entry is authorized. Clearance is confirmed in writing. No re-entry is permitted until fumigant levels are at or below the required safety threshold as specified by Texas Department of Agriculture regulations.
Post-Fumigation Preventive Inspection
Fumigation eliminates existing drywood colonies but leaves no residual protection against future re-infestation. David offers a post-fumigation inspection and discussion of ongoing preventive measures — particularly relevant for older Heights and Montrose homes near mature tree canopy.
How Termite Fumigation Works in Houston
Inspection, species confirmation, logistics coordination, tent, aeration, and clearance.
- 1
Drywood Termite Inspection and Confirmation
David inspects the structure for drywood termite evidence — frass pellets, exit holes, and gallery damage in attic framing, sills, and wood members. Fumigation is only recommended when drywood activity is confirmed across multiple areas of the structure.
- 2
Logistics Preparation
Neighbor notification letters, gas utility shutoff scheduling, and resident preparation instructions are coordinated before the fumigation date. Occupants and pets must vacate for 2-3 days. All food items in sealed packaging must be either removed or bagged with approved fumigation bags.
- 3
Tent and Gas Application
The structure is covered with tarps and sealed. Sulfuryl fluoride gas is introduced and maintained at concentration levels effective against drywood termite colonies throughout the full structure — including attic framing, wall voids, and floor members.
- 4
Aeration and Re-Entry Clearance
After the required exposure period, the tent is removed and the structure is aerated. Gas concentration is measured throughout the home and a clearance certificate is issued when levels confirm it is safe to re-enter.
Fumigation vs Spot Treatment for Drywood Termites
How to determine which drywood termite treatment is right for your Houston home.
| Feature | Structural Fumigation | Spot Treatment Only |
|---|---|---|

Case Study
Heights Craftsman: Whole-Structure Drywood Fumigation After Frass Found in Three Attic Sections
The Problem
A homeowner in The Heights discovered frass pellets in two bedrooms and a hallway over a three-month period. A visual inspection of the attic found drywood termite galleries in plank sheathing in three separate sections of the roof framing. The colonies were not connected — each was independent, which ruled out spot treatment as a practical solution.
Our Solution
David confirmed the drywood species through frass pellet morphology and gallery inspection. He assessed the extent of infestation — three separate colonies in the attic, plus evidence of a fourth in an exterior window frame — and recommended whole-structure fumigation given the number and distribution of active sites. He coordinated neighbor notification, gas shutoff, and food preparation for the 3-day process.
The Outcome
The fumigation was completed without incident. Post-aeration gas clearance was confirmed before re-entry. A 30-day post-fumigation inspection found no new frass deposition in any of the four previously active areas. David noted two exterior wood members with moisture exposure that could attract future re-infestation and provided written recommendations for exterior painting and caulking.
Termite Fumigation FAQs for Houston Homeowners
How do I know if I need fumigation or spot treatment for termites?
Fumigation is appropriate for drywood termite infestations spread across multiple areas of the structure that cannot be individually accessed for spot treatment. If the infestation is localized to one area — a single window frame, a specific roof section — spot treatment with termiticide injection or heat may eliminate the colony without full tenting. David inspects and confirms the scope before any recommendation.
How long does termite fumigation take in Houston?
The full process takes 2-3 days from tent setup through aeration and re-entry clearance. Day one covers tent installation and gas introduction. Day two maintains concentration. Day three covers aeration, gas measurement, and clearance certification. Occupants and pets must be out for the full duration.
What do I need to do to prepare for termite fumigation?
Remove or bag food items in approved Nylofume bags, remove plants and pets, coordinate gas utility shutoff, notify adjacent property occupants, and make arrangements for 2-3 days of alternative accommodation. Resolve provides a detailed preparation checklist with the fumigation scheduling confirmation.
Does fumigation leave a residual that prevents future termites?
No. Sulfuryl fluoride fumigant dissipates completely during aeration — it leaves no residual protection in the wood. Fumigation eliminates existing colonies but does not prevent future re-infestation. Post-fumigation preventive measures — sealing wood exposure, maintaining paint integrity on exterior wood — reduce re-infestation risk.
Is termite fumigation safe for my home's structure and contents?
Sulfuryl fluoride at approved fumigation concentrations does not damage structure, furnishings, fabrics, or electronics when applied correctly. The fumigant is a gas that penetrates all areas and dissipates during aeration. Food items in original sealed packaging require the extra protection of approved bags — David's preparation instructions cover all content categories.
Can drywood termites re-infest after fumigation?
Yes. Fumigation eliminates existing colonies but does not prevent new swarmers from landing on the structure and establishing new colonies. In Houston's climate, drywood termite swarmers are active in late summer and fall. Sealing exposed wood surfaces, maintaining exterior paint, and scheduling a periodic inspection are the best ongoing preventive steps after fumigation.
