How Much Does Termite Treatment Cost in Houston?

Last updated: May 26, 2026

By Pest Control Pricing Team

Termite treatment in Houston costs $275 to $2,500 in 2026, with most single-family homeowners paying $700 to $1,400 for a full perimeter treatment. Liquid barrier treatments using fipronil-based Termidor SC run $275 to $900, Sentricon bait station installations cost $900 to $1,600, and a combination approach for Formosan-infested homes runs $1,400 to $2,500. Houston sits inside the heaviest termite pressure zone in the United States according to the Termite Infestation Probability Zone map (TIP Zone 1, Very Heavy), which is why pricing here skews toward more durable treatment systems than in lower-pressure metros. For national pricing benchmarks, see the national termite treatment cost guide; for broader pest categories in the metro, the Houston pest control cost guide covers ants, cockroaches, mosquitoes, and rodents.

What homeowners actually pay for termite treatment in Houston

The "average" Houston termite bill obscures a wide spread because two homes a block apart can need fundamentally different treatments. A 1,800-square-foot slab home in Pearland with localized subterranean activity might be treated for $550. A 3,200-square-foot pier-and-beam home in the Heights with confirmed Formosan presence and a damaged sill plate can run $2,200 before any repair work. The variables that move the price are foundation type, linear footage of perimeter, soil access, termite species, infestation severity, and whether the homeowner buys into an annual bond.

Houston pricing carries a small premium over the national median because of three local factors. First, Formosan subterranean termites (Coptotermes formosanus) are entrenched in the metro and require larger termiticide volumes and more aggressive monitoring than Eastern subterranean colonies. Second, expansive Beaumont clay shrinks during dry spells and shifts soil away from foundations, creating voids that re-expose treated soil and trigger retreatment. Third, the high water table near Buffalo Bayou, White Oak Bayou, and the coastal flatlands south of Highway 90 can dilute soil-applied termiticide unless the technician adjusts product concentration and trench depth. None of these factors are present in Dallas or Phoenix at the same intensity, which is why those metros run 8 to 15 percent cheaper for an identical home footprint.

The pricing in this guide reflects 2026 rates from licensed Houston operators carrying the Texas Department of Agriculture (TDA) Structural Pest Control Service certification, which replaced the older Texas Structural Pest Control Board in 2007. All operators referenced here are required to hold a Certified Applicator license under Category 7B (Pest Control) or 7F (Wood-Destroying Insects) depending on scope.

Houston termite treatment costs by method (2026)

The table below shows current Houston pricing across the four treatment categories used by TDA-licensed operators in the metro. National medians from the subterranean termite treatment cost guide are shown alongside for comparison.

Liquid barrier treatments using Termidor in Houston

Liquid barrier treatment remains the workhorse method in Houston, used on roughly 65 percent of treated homes in the metro according to NPMA regional survey data. The most common product is Termidor SC, a fipronil-based non-repellent termiticide manufactured by BASF. A 1,800-square-foot Houston slab home with 160 linear feet of treatable perimeter typically takes 4 gallons of finished dilution applied at 0.06 percent active ingredient, which is the label rate for new construction and post-construction perimeter treatments.

Mechanism matters here because non-repellent chemistry is what makes fipronil work in Houston's heavy soil. Termites cannot detect fipronil in soil and continue to forage through the treated zone, picking up lethal doses and transferring them to nestmates through trophallaxis (mouth-to-mouth feeding) and grooming. This horizontal transfer effect is why a properly applied Termidor SC barrier can collapse an entire subterranean colony within 90 days, not just the foragers that crossed the trench.

Termidor HE is the same active ingredient but formulated with a high-efficiency soil dispersion package that spreads farther from each injection point. Houston operators use HE on properties where trenching the full perimeter is impractical: brick-veneer homes with no soil gap at the slab edge, properties with mature live oaks whose roots block trenching, and townhomes with shared foundation walls. HE injection costs $450 to $1,400 because the product itself runs roughly $90 per gallon at distributor pricing versus $65 for SC, and the labor profile is different (more drilling, less trenching).

Houston clay holds fipronil well once it bonds to soil organic matter, but the seasonal wet-dry cycle creates a treatment durability question. Beaumont clay shrinks during summer drought, opening cracks that reach 18 inches deep in untreated soil. When the rains return, those cracks close around fresh untreated soil, effectively creating bypass pathways through the original barrier. This is why most Houston operators recommend a thorough retreat or transition to a bait system around year 5, not the 8 to 10 years that label data suggests in less expansive soils.

Sentricon and bait station systems in Houston

Sentricon Always Active is the dominant bait system in Houston, with Advance Termite Bait System (BASF) running second. A Sentricon installation places 8 to 14 in-ground stations around the home perimeter, spaced 10 to 20 feet apart and recessed flush with the soil. Each station holds a cellulose matrix infused with noviflumuron, a chitin synthesis inhibitor that prevents termites from molting. Foragers consume the bait, return to the colony, and trigger a slow-acting kill that propagates across the entire population over 90 to 180 days.

Installation in Houston runs $900 to $1,600, including the first year of monitoring. Annual monitoring after year one runs $250 to $400 and is what keeps the system active; the bait matrix itself is replaced as termites consume it during station visits. Sentricon works particularly well in Houston for two reasons. First, the always-active bait means foragers find termiticide immediately on first visit, unlike older monitoring-first systems that required a switch from wood to bait. Second, the station footprint avoids the heavy trenching that pier-and-beam homes in older neighborhoods make logistically difficult.

The tradeoff with bait systems is the absence of a soil barrier. Until the colony collapses, foragers can still enter the structure. For active infestations with visible damage, Houston operators typically combine a liquid barrier (immediate kill in the soil at entry points) with bait stations (long-term colony elimination). That combination runs $1,400 to $2,500 and is the standard approach for confirmed Formosan presence or for homes where the homeowner found wings indoors during the most recent swarm season.

Formosan termites and the Houston pricing premium

Formosan subterranean termites have been established in Harris County since the 1960s and now appear in roughly 30 percent of confirmed termite jobs in the inner-loop neighborhoods. Their behavioral profile drives both treatment complexity and price.

Colony size is the headline variable. A mature Formosan colony contains 1 to 10 million individuals across a foraging area of up to 300 feet. Native Eastern subterranean colonies (Reticulitermes flavipes) top out around 250,000 individuals across a 100-foot foraging area. The Formosan biomass advantage means damage accumulates 4 to 10 times faster, and the foraging radius means a single colony can serve multiple structures on a city block. When operators find Formosan evidence on one home, they often recommend the neighbors inspect.

Above-ground carton nests separate Formosans from natives in a way that matters for treatment design. Formosans build moisture-retaining carton material from masticated wood, saliva, and frass, and they can sustain that nest above ground without returning to soil. A carton nest in a wall void or attic can survive soil-applied termiticide barriers entirely. Houston operators trained in Formosan work use a combination of foam-injected termiticide (typically Termidor Foam) for the carton nest plus a perimeter soil barrier plus baiting, which is why combination jobs run $1,400 to $2,500.

Swarm timing also separates the two species. Eastern subterranean swarms occur during late morning, February through May, after warm rain. Formosan swarms happen in the evening, May through June, often around porch lights and street lights. Houston homeowners who see large clouds of winged termites circling outdoor lighting after dusk in late May should treat that as a strong Formosan indicator and schedule inspection within 72 hours. For pricing on the combination treatment approach Formosans typically require, the hybrid Formosan treatment cost guide covers the protocol in more depth.

How foundation type changes the price in Houston

Houston has roughly equal stock of slab-on-grade and pier-and-beam construction, with slab dominant in postwar suburbs and pier-and-beam dominant in pre-1950 inner-loop neighborhoods. Foundation type is the single largest non-species cost driver.

Pier-and-beam homes in the Heights, Montrose, Eastwood, Riverside Terrace, and parts of West University Place add 25 to 40 percent to standard treatment cost. The technician must crawl the sub-floor space to inspect floor joists, sill plates, and pier caps, then treat soil under the home in addition to the exterior perimeter. Crawl space access often requires removing skirting or vent screens, and treatment in tight crawl spaces requires hand-pumped sprayers rather than tank-mounted application. A 2,000-square-foot pier-and-beam Heights bungalow typically runs $750 to $1,400 for liquid treatment compared to $450 to $900 for a comparable Pearland slab.

Slab-on-grade homes have their own complications. Plumbing penetrations through the slab (bath traps, sewer cleanouts, refrigerator water lines) create entry points that cannot be treated from the exterior trench. Houston operators drill 1/2-inch holes through the slab at these penetrations and pump termiticide into the soil beneath using a sub-slab injection rod, sealing the hole with hydraulic cement. A typical Houston slab home has 4 to 8 such penetration points; each adds $25 to $50 in labor.

Post-tension slab construction, common in homes built after 1990 in Cinco Ranch, Cypress, and Sienna Plantation, restricts where slab drilling is permitted. The cables that pre-stress the concrete cannot be cut or drilled without compromising structural integrity. Operators rely on construction drawings to identify safe drill zones and may use Termidor HE specifically because its dispersion radius compensates for fewer injection points.

Houston neighborhoods with the highest termite pressure

Termite pressure is not uniform across the Houston metro. Soil moisture, tree cover, foundation type, and proximity to bayous all shift the local risk. The neighborhoods listed below carry the highest confirmed-infestation rates based on operator volume data.

The Heights, Montrose, and Rice Military see disproportionate Formosan and Eastern subterranean pressure because of the housing stock: pier-and-beam bungalows from the 1910s to 1940s with original heart-pine framing, untreated sill plates, and crawl spaces that retain humidity. Combined with mature pecan and live oak canopy that drops dead wood near foundations, infestation rates run 2 to 3 times the metro average. Treatment pricing here trends $900 to $1,600.

West University Place, Bellaire, and Southside Place have a mix of original 1950s slab homes and newer teardown rebuilds. The teardowns are typically slab construction with treated lumber, lower risk. The remaining original slabs from the 1950s often have plumbing on cast-iron drain lines, and corroded sections that leak below grade create the soil moisture termites need. Pricing $600 to $1,200.

Memorial, Spring Branch, and Hedwig Village sit on slightly higher ground with sandier soil pockets. Termite pressure is closer to metro average, but the high concentration of mature pine trees creates surface-level food sources. Pricing $500 to $1,100.

Pearland, Friendswood, and Clear Lake sit closer to the coast with the highest water table in the metro. Subterranean activity is heavy, Formosan presence is documented but less common than inner-loop, and treatment durability is shorter because the high water table dilutes soil termiticide. Houston operators in these areas favor Sentricon over liquid for that reason. Pricing $700 to $1,500.

Katy, Cypress, and Cinco Ranch have newer construction (1995 and later), most with post-tension slabs and treated framing lumber. Initial infestation rates are lower than inner-loop, but the master-planned tree canopy is maturing into the contact-with-foundation zone, and infestation rates are climbing year over year. Pricing $400 to $1,000.

Termite bonds and the Houston renewal market

A termite bond is an annual service contract that combines a yearly inspection with retreatment coverage. If termites return during the bond period, the company retreats the home at no additional cost. Houston bond pricing runs $235 to $425 per year for a renewal, with premium bonds adding damage repair coverage for $50 to $150 more annually.

The two bond structures used in Houston are retreat-only and retreat-plus-repair. Retreat-only is the standard, covering the cost of retreatment if termites are found during the bond period. Retreat-plus-repair adds coverage for wood replacement and labor on termite-caused damage, typically capped at $250,000 in coverage. The repair bond costs roughly twice the retreat-only bond and is most common on homes valued above $500,000 where the cap matters more than the premium.

Bond transferability varies by company. Some Houston operators allow transfer to a new owner at sale for a $50 to $150 transfer fee, which becomes a small selling point on listings. Others void the bond at change of ownership and require the buyer to start a new bond from scratch. Houston real estate transactions commonly include a 30-day buyer due-diligence window during which a Wood Destroying Insect Inspection Report (WDIIR, also called NPMA-33) is completed; if termites are found, the seller's bond status determines who pays for treatment. Buyers checking inspection reports should confirm whether a transferable bond is in place before closing.

Houston's high baseline termite pressure makes bonds genuinely useful here in a way they are not in lower-pressure metros. National data shows roughly 35 percent of homeowners maintain a termite bond; in the Houston metro the figure runs closer to 55 percent. The ROI math is straightforward: a $300 annual bond protecting a typical Houston liquid-barrier installation pays for itself the first time termites return within the warranty period and require a $700 retreatment.

Signs of termites in Houston homes

Houston's year-round warm climate means termite activity does not pause in winter the way it does in northern metros. Signs can appear in any month, though swarm season produces the highest-volume evidence.

• Mud tubes running up foundation walls, pier columns, or interior baseboards. Tubes are typically 1/4 to 1/2 inch wide and the color of local soil. Active tubes are damp and break to reveal living termites; abandoned tubes are dry and crumbly. Mud tubes are the single most reliable indoor indicator in Houston.
• Discarded wings on windowsills, near porch lights, or pooled in spider webs after a swarm. Termite wings are equal-length front and back; flying ant wings have a longer front pair. A pile of wings near a window after an evening rain in May is a strong Formosan indicator.
• Hollow-sounding wood when tapped with a screwdriver handle. Baseboards, door frames, window casings, and floor joists in pier-and-beam crawl spaces are common locations.
• Frass (termite droppings) resembling fine sawdust or coffee grounds at the base of wood surfaces, more common with drywood termites than subterranean species in Houston but worth noting.
• Buckling paint or bubbled drywall that does not match a known plumbing leak. Subterranean termites generate moisture inside galleries, and the moisture migrates through the wood into the wall surface.
• Swarmers indoors, especially in late February through May for Eastern subterranean or May through June evenings for Formosan. Swarmers indoors mean a colony is established somewhere inside or adjacent to the structure.

Homeowners who spot any of these indicators should schedule an inspection within 7 to 14 days. For pricing and what to expect from the inspection itself, the Houston termite inspection guide covers WDIIR forms, real estate timing, and inspector qualifications.

How to evaluate a Houston termite treatment company

Texas regulates structural pest control through the TDA Structural Pest Control Service. Every operator working on Houston homes must hold a Business License from the agency, and the individual applying treatment must hold a Certified Applicator credential in Category 7B or 7F. Homeowners can verify both at the TDA website (texasagriculture.gov) by company name or applicator number; the agency publishes complaint history and enforcement actions on the same lookup.

Beyond the state license, several credentials separate experienced Houston termite contractors from generalists. NPMA QualityPro certification signals a company has adopted national best-practice standards for training, safety, and customer service; QualityPro GreenPro adds IPM-focused criteria around minimal pesticide use. NPMA-33 form competency matters specifically for real estate transactions because the form requires specific language and timing. Companies that handle high transaction volume through HAR realtor referrals tend to file cleaner NPMA-33 paperwork than companies focused on residential bond renewals.

Questions worth asking before signing a treatment contract: What active ingredient and brand are you applying? What is the warranty length and what does it cover? Is the warranty transferable at sale? What does the annual bond renewal cost, and what does it include? Will the work be done by a certified applicator or a technician under supervision? What is the per-foot trenching rate, and how is sub-slab drilling priced? Companies that answer these questions clearly are easier to work with mid-project than companies that quote a flat number with no detail.

Red flags in Houston specifically: companies that quote significantly below market without explaining how (often a sign of diluted product or skipped sub-slab work), companies that recommend tent fumigation for subterranean termites (fumigation is for drywood termites only, which are uncommon in inland Houston), and companies that pressure homeowners during the door-knock follow-up to a neighbor's swarm event. The Better Business Bureau and TDA enforcement records both surface complaint patterns worth checking before signing.

How Houston compares to other Texas and Sunbelt metros

Houston termite treatment runs slightly above the Texas median because of Formosan pressure and Beaumont clay treatment durability issues. Dallas termite treatment runs 8 to 12 percent cheaper on average because Dallas has lower Formosan presence and less expansive soil. San Antonio prices closely track Houston with slightly easier access to limestone-based soils that hold barriers longer. New Orleans and Tampa run comparable to Houston because both share Formosan establishment and Gulf Coast moisture profiles. Phoenix and Las Vegas run 15 to 20 percent cheaper because the desert ecology favors drywood termites over subterranean, and drywood spot treatments cost less than full perimeter work.
