Termite Treatment Cost in Houston: 2026 Price Guide
Last updated: March 5, 2026
Termite treatment cost in Houston ranges from $275 to $2,500, with the average homeowner paying around $700. Houston sits in one of the heaviest termite zones in the US, with Eastern subterranean termites causing significant damage across the metro. Formosan termites are well established in Houston and cause damage up to 10 times faster than native species. The city's high water table, clay soil, and warm humid climate create ideal conditions for year-round termite activity.
This guide covers termite treatment pricing specific to the Houston metro, including Katy, Sugar Land, The Woodlands, Pearland, and surrounding areas. For national pricing, see our termite treatment cost guide. For general pest control in the area, see our Houston pest control cost guide.
Houston Termite Treatment Costs by Method
| Treatment Method | Houston Cost | National Average | Best For |
|---|---|---|---|
| Liquid barrier (Termidor) | $275 – $900 | $300 – $900 | Most Houston homes, subterranean termites |
| Bait station system | $800 – $1,500 | $800 – $1,500 | Ongoing monitoring, colony elimination |
| Combination (liquid + bait) | $1,200 – $2,500 | $1,200 – $2,500 | Formosan termites, severe infestations |
| Spot treatment | $150 – $400 | $200 – $500 | Localized infestations caught early |
| Termite bond (annual) | $200 – $400/yr | $250 – $500/yr | Annual inspection + re-treatment coverage |
Liquid Barrier Treatments
Liquid barrier treatment is the most common method in Houston, costing $275 to $900 depending on home size and foundation type. A termiticide (typically Termidor) is applied in a trench around the foundation, creating a continuous chemical barrier in the soil. Termites crossing the treated zone are killed and transfer the product to nestmates through contact.
Houston's heavy clay soil retains termiticide well, but the high water table can dilute treatments in some areas, particularly in flood-prone zones. A properly applied treatment lasts 5 to 10 years. Homes in areas with higher water tables may benefit from a combination of liquid treatment and bait stations for maximum protection.
Formosan Termites in Houston
Formosan subterranean termites are well established in the Houston metro and represent the most destructive termite threat in the region. Key facts about Formosan termites in Houston:
- Colony size. Formosan colonies contain several million individuals, compared to hundreds of thousands for native Eastern subterranean termites. This means they consume wood and cause structural damage significantly faster.
- Above-ground nests. Formosan termites can build moisture-retaining carton nests above ground, allowing them to survive without returning to soil. This makes them harder to control with soil-applied barriers alone.
- Evening swarms. Formosan termites swarm during evening hours in May and June, often attracted to street lights and porch lights. Finding large winged termites around exterior lights is a strong indicator of a nearby Formosan colony.
- Treatment approach. Formosan infestations often require a combination of liquid barrier and bait stations ($1,200 to $2,500) for effective control. Ongoing monitoring is essential because Formosan colonies can survive partial treatments.
Pier and Beam vs. Slab Foundations
Houston has a mix of foundation types, and the type affects both termite vulnerability and treatment cost:
- Pier and beam foundations are common in older neighborhoods like the Heights, Montrose, and West University. These homes have a crawl space beneath the floor, providing wood-to-soil proximity that termites exploit. Treatment is more complex and typically costs 20 to 30% more than slab homes because the technician must access and treat the crawl space.
- Slab-on-grade foundations are standard in newer Houston construction. Treatment involves trenching around the exterior perimeter and may include drilling through the slab to treat soil beneath in areas where plumbing penetrates (bath traps). Slab homes are generally less expensive to treat.
Termite Bonds in Houston
Termite bonds are standard practice in Houston and cost $200 to $400 per year. A bond includes an annual professional inspection and re-treatment at no additional cost if termites are found. Some bonds also include damage repair coverage.
Given Houston's extreme termite pressure, maintaining a termite bond is strongly recommended. The annual cost is a fraction of what treatment and repair would cost if an infestation goes undetected. The Texas Structural Pest Control Board requires licensing for termite treatment, ensuring that bonded treatments meet professional standards.
Termite Inspections in Houston
Texas does not require termite inspections for home sales, but most mortgage lenders require a Wood Destroying Insect (WDI) report. The inspection costs $75 to $150 and is typically paid by the buyer. For more detail, see our termite inspection cost guide.
Signs of Termites in Houston
Watch for these indicators, especially during swarm season (February through June):
- Mud tubes running up foundation walls, in crawl spaces, or along interior walls
- Winged termites or shed wings near windows, doors, or around exterior lights (evening Formosan swarms)
- Damaged wood that sounds hollow when tapped, particularly in baseboards, door frames, and window sills
- Moisture damage that seems unrelated to plumbing, which can indicate termite-caused wood decay

What Affects Termite Treatment Cost in Houston
- Foundation type. Pier and beam homes cost more to treat than slab-on-grade.
- Home size. Larger homes require more termiticide and longer treatment times.
- Termite species. Formosan termites may require a combination approach at higher cost.
- Infestation severity. Early detection (spot treatment $150 to $400) costs far less than established infestations requiring full perimeter treatment.
- Water table. Homes in flood-prone areas may need supplemental bait stations alongside liquid treatment.
