“Frass under a bedroom window frame. David inspected the attic and the rest of the house carefully, confirmed it was an isolated colony, and treated the window frame in the same visit. Problem solved without a hotel stay.”

Drywood Termite Spot Treatment in Houston, TX
Spot treatment by wood injection eliminates localized drywood termite colonies without tenting, displacement, or full-structure preparation. The right choice when the inspection confirms all active colonies are in accessible locations.
- Direct wood injection for accessible colonies — no tent, no hotel stay
- Completed in 1-3 hours with no displacement required
- Thorough inspection confirms spot treatment is appropriate before work begins
- Written warranty on all spot-treated locations
Why Spot Treatment Is the Right Choice for Accessible Drywood Infestations
When drywood colonies are localized and accessible, spot treatment eliminates them without the disruption or cost of full-structure fumigation.
- No displacement — treatment completed while you remain at home
- Completed in a single visit, typically 1-3 hours for one to three locations
- Direct injection reaches the colony inside the wood — not just the surface
- Effective for window frames, door frames, exposed rafters, furniture, and trim
- Significantly less disruptive and less costly than full-structure fumigation
- Written warranty on treated locations — re-treatment at no charge if activity returns
Houston Homeowners on Drywood Spot Treatment
No Fumigation Needed Single Visit 5-Star Rated
“Two active locations — a door frame and a section of closet trim. Resolve treated both in one visit. No need to pack up the house or make hotel reservations. The warranty gave us confidence.”
“Drywood termites in an antique armoire from an estate sale. Resolve treated the piece directly and inspected the rest of the home. No structural treatment needed. That kind of honest assessment is exactly what I wanted.”
What Drywood Spot Treatment Covers
Spot treatment reaches any accessible wood member where drywood frass confirms active colony presence.
Window Frame Treatment
Frass below window frames indicates colony activity within the frame or adjacent trim. Direct injection delivers termiticide to the colony inside the wood.
Door Frame Treatment
Door frames — particularly in older Houston homes with original wood framing — are a common drywood colony location, especially on exterior-facing doors.
Exposed Rafter Treatment
Attic rafters visible from pull-down access can often be spot-treated without full fumigation when colonies are isolated and accessible.
Trim and Baseboard Treatment
Drywood colonies in window trim, baseboard, or decorative wood members are prime spot treatment candidates when infestation is confirmed as localized.
Furniture and Antique Treatment
Drywood termites in portable items — chairs, dressers, antique doors — can be treated directly, preventing spread to structural wood in the home.
Post-Treatment Monitoring
Follow-up inspection confirms frass production has stopped and verifies that no additional colonies were missed in the initial assessment.
How Drywood Spot Treatment Works
From frass location to injection to post-treatment confirmation.
- 1
Frass Mapping and Inspection
We locate frass deposits, probe suspect wood for hollow sounds, and confirm the full infestation extent before recommending spot treatment.
- 2
Accessibility Confirmation
We confirm all active colonies are in accessible wood members where direct injection can reach the colony. If inaccessible locations are found, fumigation is discussed honestly.
- 3
Direct Injection
Small holes are drilled into infested wood members and licensed termiticide is injected at the appropriate rate to reach the colony. Holes are sealed after treatment.
- 4
Follow-Up Confirmation
A follow-up inspection confirms frass production has stopped — the most reliable indicator that the colony has been eliminated.
Spot Treatment vs Tent Fumigation for Drywood Termites
Spot treatment is the better choice for accessible infestations — fumigation is necessary for widespread ones.
| Feature | Spot Treatment | Tent Fumigation |
|---|---|---|
| Appropriate for accessible, localized colonies | ✓ | Overkill |

| Completed in a single afternoon | ✓ | ✗ |
| Reaches inaccessible wall cavities and framing | ✗ | ✓ |
| Eliminates all colonies simultaneously | Accessible only | ✓ |

Case Study
Two-Location Spot Treatment Saves a Heights Homeowner from Unnecessary Fumigation
The Problem
A Houston Heights homeowner found frass in two locations — a bedroom window frame and a section of attic trim visible from the pull-down access. Another pest control company had quoted full-structure fumigation at more than four times the spot treatment cost without performing a complete structural inspection.
Our Solution
Resolve conducted a full inspection including the complete attic, all closets, and all wood trim. Both active colonies were confirmed as accessible — one through direct window frame injection and the attic trim section through a clear access point. Spot treatment was performed at both locations in a single two-hour visit.
The Outcome
Frass production at both locations stopped within two weeks. The 6-month follow-up found no new activity anywhere in the structure. The homeowner saved the significant cost and disruption of fumigation because the inspection supported a different, accurate recommendation.
Drywood Spot Treatment FAQs
How do I know if spot treatment will work for my situation?
Spot treatment is effective when all active colonies are in accessible wood members where direct injection can reach them. An inspection maps the full infestation and confirms whether spot treatment is appropriate or whether inaccessible colonies require fumigation.
Does spot treatment leave anything behind in the wood?
A small amount of dried termiticide remains inside the drilled injection holes after treatment. It is sealed within the wood, not on the surface. No residue is left on surrounding surfaces, finishes, or materials.
How many holes are drilled for spot treatment?
The number of injection points depends on the infestation location and the specific wood member dimensions. Resolve uses the minimum number of injection points needed to reach the colony based on frass pattern and wood size.
What if more colonies are found after spot treatment?
If frass production continues from a previously treated location or appears in a new location, we reassess. Continued activity may indicate a missed colony or a new introduction. Re-treatment on warranted locations is provided at no charge.
Can spot treatment be done on furniture?
Yes. Drywood termites in portable wood items — furniture, antiques, doors — can be treated by direct injection without any treatment to the home structure.
