“Found mud tubes in two corners of the garage. Resolve identified Formosan termites, applied a full perimeter barrier, and installed bait stations at the corners closest to the neighbor's treeline. Zero activity at both six-month follow-ups.”

Subterranean Termite Control in Houston, TX
Eastern subterranean and Formosan termite colonies require elimination at the colony source — not surface suppression. Professional liquid barriers and bait stations that carry the active ingredient back to eliminate the nest.
- Species identification confirms Eastern or Formosan before treatment begins
- Non-repellent liquid barrier with colony transfer effect
- Bait stations for Formosan pressure management in high-activity zones
- 1-year renewable warranty on every subterranean treatment
Why Professional Control Works Where DIY Products Fail
Colony elimination requires the right product placed correctly at the colony's access points — neither available in consumer channels.
- Professional fipronil is non-repellent — termites walk through and carry it back to the colony
- Full-perimeter application with no gaps — gaps allow colonies to route around treated soil
- Species identification shapes treatment — Formosan requires different urgency than Eastern subterranean
- Bait stations provide sustained Formosan pressure management in high-forager-density zones
- Annual monitoring keeps barriers current against Houston's year-round termite climate
- 1-year renewable warranty — re-treatment at no charge if activity returns
Houston Homeowners on Subterranean Termite Control
Colony Eliminated Formosan Specialists 5-Star Rated
“Eastern subterranean termites in a pier-and-beam crawlspace. Resolve applied the barrier around the full foundation perimeter, confirmed the entry points were addressed, and the six-month inspection was clean.”
“Formosan pressure in our neighborhood is constant in swarmer season. Resolve set up protection before I saw any activity at my home. Two full swarmer seasons and the monitoring has been clean.”
Subterranean Termite Control Services
The right combination of methods for your property, the species found, and the infestation extent.
Species Identification
Eastern subterranean and Formosan termites require different treatment urgency and protocols. We confirm species before selecting the treatment approach.
Liquid Barrier Treatment
Full-perimeter non-repellent termiticide in the soil around the foundation. Foragers pass through without detecting it and carry the active ingredient back to eliminate the colony source.
Bait Station Systems
In-ground stations installed at foraging intervals around the property intercept workers and deliver colony-eliminating bait over 8-12 weeks.
Void and Wood Injection
For identified entry points into structural voids or wood members, targeted termiticide injection addresses active areas directly alongside the perimeter treatment.
Slab Foundation Treatment
For slab-foundation homes with confirmed sub-slab activity, termiticide is injected through drilled ports to treat soil beneath the concrete where trenching cannot reach.
Annual Monitoring Plans
Yearly barrier inspection and condition check. Houston's year-round Formosan forager pressure makes annual monitoring essential for maintaining continuous protection.
How Subterranean Termite Control Works
From species identification to colony elimination and ongoing protection.
- 1
Inspection and Species ID
We confirm the species — Eastern subterranean or Formosan — because colony size, treatment urgency, and method selection differ significantly between the two.
- 2
Treatment Plan
Based on the species found, infestation extent, and property layout, we recommend liquid barrier, bait stations, or a combined approach. Written quote before any work begins.
- 3
Professional Application
Liquid termiticide is applied via trenching and rodding around the full foundation perimeter. Bait stations are installed at soil level at identified foraging intervals.
- 4
Monitoring and Warranty
Follow-up confirms treatment effectiveness. Written 1-year renewable warranty covers re-treatment if activity returns. Annual monitoring keeps protection active.
Liquid Barrier vs Bait Stations for Subterranean Termite Control
Both methods eliminate colonies — the best approach often combines them.

| Best for limited soil access areas | ✗ | ✓ |
| Excellent for ongoing Formosan pressure management | ✗ | ✓ |
| Colony transfer effect reaches queen | ✓ | ✓ |

Case Study
Full Colony Elimination for an Active Formosan Infestation in Sugar Land
The Problem
A Sugar Land homeowner contacted Resolve after finding mud tubes in the garage, swarmers in the master bedroom, and visible damage to one door frame. The home sat near adjacent undeveloped lots with known Formosan forager pressure.
Our Solution
Resolve confirmed Formosan termites through species identification, performed a full-perimeter liquid barrier treatment, and installed six bait stations at corners nearest the adjacent pressure zones.
The Outcome
Mud tube construction stopped within two weeks of treatment. The 6-month follow-up found no live termites and no new tube construction. The combined approach continues to maintain colony-free status at each annual monitoring visit.
Subterranean Termite Control FAQs
How long does subterranean termite control take to work?
Forager activity typically slows within days of liquid barrier application as the transfer effect begins working through the colony. Eastern subterranean colonies typically collapse within 2-4 weeks. Formosan colonies may take longer due to larger colony size.
Do I need to leave my home during treatment?
No. Liquid barrier treatment is applied to the soil outside your foundation — no evacuation is required. Treatment involving interior wood void injection may require briefly vacating the specific room being treated.
How does the non-repellent transfer effect work?
Professional fipronil-based termiticide is non-repellent — termites cannot detect the treated zone and walk freely through it. They carry the active ingredient back on their bodies and transfer it to nestmates through grooming and contact, eventually reaching the queen and colony source.
Is there a warranty on subterranean termite control?
Yes. Every Resolve subterranean treatment includes a 1-year renewable warranty. If termites return to treated areas within the warranty period, re-treatment is provided at no charge. Annual monitoring renewals keep the warranty active year over year.
What is the difference between Eastern subterranean and Formosan termites?
Both are soil-based species, but Formosan colonies are significantly larger — sometimes containing millions of workers compared to a few hundred thousand in Eastern subterranean colonies. Formosan termites require more aggressive treatment protocols and are particularly active across the Houston metro.
