“Had a significant Formosan infestation — mud tubes in the garage and swarmers throughout the spring. David identified the species, applied a full barrier and bait stations, and we've had zero activity at every follow-up. The warranty and monitoring plan made the investment easy to commit to.”

Subterranean Termite Treatment in Houston, TX
Houston's two most destructive subterranean species — Eastern subterranean and Formosan termites — require colony-level elimination, not surface suppression. Liquid barriers and bait stations that target the colony source.
- Targets both Eastern subterranean and Formosan termite colonies
- Non-repellent liquid barrier with colony-transfer effect
- Professional bait station systems for Formosan pressure management
- 1-year renewable warranty on every treatment
Why Subterranean Termite Treatment in Houston Requires a Specific Approach
Subterranean termites — those that maintain soil-based colonies and forage underground — are the dominant destructive species in the Houston area. Two species are active here: Eastern subterranean termites, which are widespread throughout Harris and surrounding counties, and Formosan termites, an invasive species introduced to the Gulf Coast that has established dense population pressure throughout the Houston metro.
What makes Formosan termites particularly challenging in Houston is colony size. A mature Formosan colony can contain millions of workers — significantly more than Eastern subterranean colonies — and can consume wood faster, establish secondary carton colonies within structures, and maintain multiple foraging galleries simultaneously. No consumer-grade product is rated to eliminate a Formosan colony.
Effective subterranean termite treatment requires placing the right product in the right locations to reach the colony source — not just block surface activity. A non-repellent liquid barrier works because foragers pass through it without detection, carry the active ingredient back to the colony, and transfer it to nestmates through normal contact. Bait systems achieve the same result through a slower but equally effective delivery mechanism.
Why Houston Homeowners Trust Resolve for Subterranean Termite Treatment
Species expertise, professional-grade products, and a colony-level elimination strategy backed by a written warranty.
- Species identification confirms whether Eastern or Formosan — treatment strategy differs by species
- Non-repellent fipronil-based liquid barrier with colony transfer effect
- Professional bait stations for Formosan pressure management in high-forager-pressure areas

- Written 1-year renewable warranty with free re-treatment if activity returns
- Annual monitoring to keep the barrier current against new Formosan foraging pressure
Subterranean Termite Treatment Methods
The right method depends on the species found, the infestation extent, and your property's construction.
Liquid Termiticide Barrier
Full-perimeter application of non-repellent termiticide in the soil around your foundation. Foragers pass through and carry it back to eliminate the colony at the source.
Bait Station Systems
In-ground stations installed around the property perimeter intercept foraging workers. Colony-eliminating bait is collected and transferred to the nest over 8–12 weeks.
Combined Barrier + Bait
For active Formosan infestations with high colony pressure, a combined approach accelerates elimination and provides long-term population management.
Void and Wood Injection
For subterranean activity with identified entry points into wall voids or wood members, targeted injection delivers termiticide directly to active areas.
Slab Injection
For slab-foundation homes with confirmed sub-slab termite activity, termiticide is injected through drilled ports directly into the soil beneath the concrete.
Annual Monitoring Plans
Yearly inspection and barrier condition check. Houston's year-round termite climate means active Formosan forager pressure is constant — annual monitoring keeps protection current.
How Subterranean Termite Treatment 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 between them.
- 2
Treatment Plan
Based on the 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 by 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 warranty covers re-treatment if termites return. Annual monitoring keeps protection active and the warranty renewed.
Houston Homeowners on Subterranean Termite Treatment
Formosan Specialists Colony-Level Elimination 5-Star Rated
“Subterranean termites were working through the crawl space. Resolve's inspection was thorough — they found entry points we hadn't noticed. The liquid barrier eliminated the problem and the annual monitoring keeps us protected.”
“The Woodlands has constant Formosan foraging pressure from wooded areas. Resolve set up bait stations at the property corners nearest the trees. Two swarmer seasons later and no penetration. Worth every dollar.”
Case Study
Eliminating an Active Formosan Colony in a Katy Slab-Foundation Home
The Problem
A Katy homeowner found active mud tubes running from the soil through an exterior brick weep hole into a living room wall. Swarmers had appeared for two consecutive springs, indicating an established Formosan colony. The slab foundation limited standard trenching access.
Our Solution
Resolve performed a full perimeter inspection, confirmed Formosan termites with multiple entry points along the south and west walls, applied a liquid barrier via soil injection through drilled ports in the slab, and installed four bait stations at identified foraging locations adjacent to the property.
The Outcome
Mud tube construction stopped within three weeks. The 6-month follow-up found no live termites and no new tubes. The combined liquid-plus-bait approach has maintained colony-free status through two subsequent annual inspections.
Subterranean Termite Treatment FAQs
What is the difference between Eastern subterranean and Formosan termites?
Both are subterranean species that forage underground and enter structures from the soil. Formosan termites have significantly larger colonies — sometimes 10x more workers — and can establish carton colonies within structures independent of soil contact. They require more aggressive treatment protocols and are particularly active in the Houston area.
How does a liquid termiticide barrier eliminate a colony?
Professional-grade liquid termiticides like fipronil are non-repellent — termites cannot detect them and pass through the treated soil freely. They carry the active ingredient back to the colony and transfer it to nestmates through grooming and feeding. This transfer effect eliminates the colony source rather than just blocking foragers at the perimeter.
How long does subterranean termite treatment take?
A liquid barrier treatment for an average Houston home takes 2–4 hours. Bait station installation adds another 30–60 minutes depending on property size. Both can typically be completed in a single visit.
Will I need to leave my home during treatment?
For liquid barrier treatment, no evacuation is required. The termiticide is applied to the soil outside the foundation — you do not need to vacate unless the treatment involves interior wood injection, which may require brief vacating of the specific room.
How do I know if the treatment worked?
Forager activity typically slows within days of a liquid barrier application as the transfer effect works through the colony. Full colony elimination for Eastern subterranean colonies typically occurs within 2–4 weeks. Formosan colonies may take longer depending on colony size. Follow-up inspection confirms activity has stopped.
Does subterranean termite treatment include a warranty?
Yes. Every Resolve subterranean termite 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.
