Termite Inspection Houston TX (2026 Cost)
Last updated: March 30, 2026
A termite inspection in Houston costs $75 to $200, with the average homeowner paying around $125 for an independent evaluation. Houston sits in one of the heaviest termite pressure zones in the United States, with year-round activity from both native eastern subterranean termites and the more aggressive Formosan subterranean termite. The combination of hot, humid weather that never produces a hard freeze, heavy clay soil that retains moisture against foundations, over 50 inches of annual rainfall, and Gulf Coast proximity creates conditions where termite colonies thrive 12 months a year. Regular professional inspections are not optional for Houston homeowners. They are a necessary part of protecting the largest investment most families will ever make.
This guide covers what Houston homeowners need to know about termite inspections, including costs, the inspection process, how Houston's climate and construction create unique challenges, neighborhood-specific risk factors, and what treatment costs if termites are found.

What Termite Species Are in Houston?
Houston has three termite species that pose a threat to residential structures. Understanding which species are present in the metro area is important because different species behave differently, swarm at different times, and require different inspection approaches.
Eastern subterranean termites (Reticulitermes flavipes) are the most common termite species in the Houston metro. These termites build colonies underground in the soil and access structures by constructing mud tubes along foundation walls, through cracks in concrete slabs, and via plumbing penetrations. A mature eastern subterranean colony typically contains 60,000 to several hundred thousand workers. They consume wood from the inside out, leaving exterior surfaces intact until damage is severe. Worker termites are small, soft-bodied, and cream-colored, and they never voluntarily expose themselves to open air. The only time most homeowners see eastern subterranean termites is during swarm season, when the reproductive caste (dark-bodied, winged swarmers) emerges from mature colonies to mate and establish new colonies.
Eastern subterranean termites are found throughout the entire Houston metro, from Galveston County in the south to Montgomery County in the north, and across Harris, Fort Bend, Brazoria, and Liberty Counties. There is no neighborhood, subdivision, or part of the metro that is free from eastern subterranean termite activity. Every residential structure in greater Houston is within foraging range of eastern subterranean colonies, and the favorable climate means these colonies are active year-round rather than going dormant during winter months as they do in northern states.
Formosan subterranean termites (Coptotermes formosanus) have been established in the Houston area since the 1990s and represent the most destructive termite threat in the metro. Originally from East Asia, Formosan termites were introduced to the southern United States through ports, and Houston's port activity and Gulf Coast location made it one of the early establishment points in Texas. Formosan termites are now confirmed throughout Harris County and the surrounding metro area.
Formosan termites are categorically more destructive than native eastern subterranean termites for several reasons. A single Formosan colony can contain several million workers, compared to a few hundred thousand for an eastern subterranean colony. This means a Formosan infestation has far more workers consuming wood at any given time, and the rate of structural damage is correspondingly faster. A Formosan colony can cause significant structural damage in as little as six months, whereas an eastern subterranean colony of typical size might take several years to produce the same level of damage.
The most distinctive behavior of Formosan termites is their ability to build carton nests inside walls and attics. A carton nest is a structure made from chewed wood, soil, and termite excrement that retains moisture. These nests allow the colony to maintain the humidity levels it needs without relying on a direct connection to the soil below. This means Formosan termites can establish self-sustaining infestations in upper walls and attics that are completely independent of the ground. Carton nests in attics are a particular concern in Houston because they can grow undetected for extended periods, producing significant damage to roof framing, rafters, and top plates before any exterior signs become visible.
Drywood termites (Incisitermes species) are uncommon in the Houston metro but occasionally appear in imported lumber, antique furniture, or older structures. Unlike subterranean termites, drywood termites do not require soil contact and infest dry, sound wood directly. They enter structures through exposed wood surfaces, typically at eaves, attic vents, and window frames. Drywood termite colonies are smaller (typically a few thousand individuals) and produce distinctive fecal pellets that look like small, six-sided granules often found in piles below infested wood. While drywood termites are not a primary concern for most Houston homeowners, inspectors check for them as part of a thorough evaluation, and their presence should not be ignored. For information on recognizing termite activity, see our signs of termites guide.
What Does a Termite Inspection in Houston Include?
A professional termite inspection in Houston follows a systematic protocol adapted to the specific challenges of the local climate, construction styles, and the presence of Formosan termites. The inspection covers the entire structure and surrounding property, with particular attention to the access points and conditions that are most relevant to Houston homes.
Exterior foundation and perimeter. The inspector walks the full perimeter of the home, examining the foundation stem wall from the soil line to the siding. They look for mud tubes on the foundation surface, cracks in the stem wall, gaps where the slab meets the stem wall (expansion joints), and any areas where soil, mulch, or landscaping has been built up against the siding above the foundation line. In Houston, inspectors pay particular attention to weep holes in brick veneer. Most Houston homes built from the 1960s onward use brick veneer over wood framing, and weep holes at the base of the brick provide ventilation for the wall cavity but also serve as a common termite entry point. Inspectors check each weep hole for evidence of mud tubes extending from the soil into the wall cavity through the weep hole opening.
Interior walls, baseboards, and trim. The inspector examines baseboards, door frames, window frames, and wood trim throughout the interior. They tap wood surfaces with a screwdriver handle or sounding tool to check for hollow sounds indicating internal consumption. In slab-on-grade homes, which are common throughout Houston, the base plate of the wall framing sits directly on the concrete slab, and this is where termites first contact structural wood after entering through the slab. Damage to door frames and baseboards at floor level is often the first interior sign of a slab entry. The inspector also checks for bubbling or discolored paint, which can indicate moisture from termite mud tubes behind the drywall.
Bathrooms and kitchens. These rooms receive extra scrutiny because every plumbing penetration through the slab is a potential termite entry point. The inspector checks around toilets, tubs, showers, sinks, and dishwashers for signs of moisture, damaged wood, and termite activity. In slab homes, the inspector may remove access panels beneath kitchen and bathroom sinks to examine the plumbing penetrations and surrounding wood for evidence of termite entry. Soft or discolored flooring around toilets and tubs that is not explained by a plumbing leak warrants closer investigation. Houston's high humidity means that moisture readings alone can be misleading, so inspectors look for the combination of moisture plus structural damage plus mud residue that distinguishes termite activity from simple condensation or plumbing issues.
Attic inspection: critical for Formosan termites. The attic inspection is especially important in Houston because of the Formosan termite threat. While standard subterranean termite inspections always include an attic check, the Formosan inspection component is more intensive. Inspectors look for carton nests in the attic, which appear as dark, spongy masses of chewed wood and soil attached to rafters, roof sheathing, or top plates. Carton nests can range from the size of a football to several feet across. The inspector also checks for mud tubes running up wall studs into the attic space, damaged roof framing, and the distinctive appearance of Formosan damage, which tends to be more diffuse and less linear than eastern subterranean damage. If Formosan carton nests are found in the attic, the infestation is typically extensive and treatment should begin immediately.
Garage inspection. The garage receives focused attention because the garage door frame sits directly on the slab edge, often with minimal separation between the wood and the exterior soil grade. Termites can access this wood by tunneling along the slab edge or through cracks in the garage slab. Water heaters located in garages create localized moisture that attracts termite activity. The inspector checks the garage door frame on both sides, the threshold area, around the water heater, and any cracks in the garage slab that could provide access from below.
Crawl space and pier-and-beam foundations. Houston has a significant number of older homes built on pier-and-beam foundations with crawl spaces, particularly in neighborhoods like the Heights, Garden Oaks, Montrose, and parts of the East End. For these homes, the crawl space inspection is a critical component. The inspector enters the crawl space and examines piers, beams, floor joists, and the underside of the subfloor for mud tubes, damage, and active termite activity. Crawl space inspections in Houston are complicated by high humidity and standing water, especially after heavy rain. The moisture levels in Houston crawl spaces are among the highest in the country, creating an ideal environment for termite colony activity near the foundation.
Attached wood structures. Porches, decks, pergolas, fences that connect to the house, and other attached wood structures are inspected for termite damage. In Houston's humid climate, these exterior wood elements are continuously exposed to moisture and are often the first point of termite contact before the colony reaches the main structure. The inspector documents any attached wood structures showing evidence of termite activity and notes whether the activity has extended to the primary structure.
A standard inspection for a typical Houston home takes 45 to 90 minutes. Larger homes, properties with crawl spaces, homes with multiple stories, and properties with extensive attached structures take longer. Homes where Formosan termites are suspected receive more intensive attic and wall cavity evaluation, which can extend the inspection time.
How Much Does a Termite Inspection Cost in Houston?
Termite inspection costs in Houston range from free (through treatment companies) to $200 for independent evaluations. The cost depends on the type of inspection, who performs it, and whether it is for general maintenance or a real estate transaction.
| Inspection Type | Houston Cost | Details |
|---|---|---|
| Independent inspection | $100 – $200 | Unbiased evaluation, no treatment pressure |
| Treatment company inspection | $0 (free) | Inspector on commission; may recommend treatment |
| Real estate WDI report | $100 – $175 | NPMA-33 standard; required for VA/FHA loans |
| Annual inspection (under bond) | $150 – $400/yr | Included with termite bond; annual monitoring |
Independent inspections ($100 to $200) are performed by licensed inspectors who charge a fee for the evaluation and provide an unbiased report of findings. The inspector has no financial incentive to recommend treatment because their compensation comes from the inspection fee, not from selling treatment services. For homeowners who want a thorough, objective assessment of their property's termite status, a paid independent inspection is the best option. The cost varies based on the size of the home, the complexity of the inspection (crawl spaces, multiple stories, attached structures), and the specific company.
Treatment company inspections ($0, free) are offered by many pest control companies as part of their sales process. The company sends a technician to inspect the property at no cost, and the technician provides a report along with a treatment recommendation and quote. While free inspections are certainly better than no inspection at all, homeowners should understand that the inspector in this scenario typically works on commission. The inspector earns a percentage of any treatment contract that results from the inspection, which creates a financial incentive to identify conditions as warranting treatment. This does not mean free inspections are unreliable, but it does mean the homeowner should consider the potential for bias when evaluating the findings.
Real estate WDI reports ($100 to $175) are formal Wood Destroying Insect reports produced on the NPMA-33 form, which is the nationally standardized inspection form used in real estate transactions. VA loans require a current WDI report for all home purchases. FHA loans require a WDI report in areas designated as having significant termite risk, and all of greater Houston falls within this designation. Most conventional lenders in the Houston market also request a WDI report as part of their standard underwriting requirements given the area's heavy termite pressure. The report must be completed by a company licensed through the Texas Department of Agriculture (TDA) Structural Pest Control Service (SPCS). The report is typically valid for 90 days from the inspection date.
TDA/SPCS licensing. Texas requires that all termite inspections and treatments be performed by companies and individuals licensed through the Texas Department of Agriculture, Structural Pest Control Service. This licensing ensures that inspectors have completed required training, passed examinations, and maintain current certifications. Homeowners should verify that the company they hire holds a current TDA/SPCS license before scheduling an inspection. You can verify licenses online through the TDA website.
Annual inspections under bond ($150 to $400 per year). A termite bond is an ongoing service agreement that includes annual inspections, guaranteed re-treatment if termites are found, and in some cases, repair coverage for termite damage that occurs during the bond period. The annual cost ranges from $150 to $400 depending on the size of the home, the treatment provider, and whether the bond includes repair coverage. Bonds are standard practice in the Houston market and represent the most cost-effective approach to long-term termite protection in an area with year-round termite pressure.

How Do Termite Inspections Work in Houston Real Estate?
Termite inspections are a standard component of real estate transactions in the Houston metro. The combination of heavy year-round termite pressure, Formosan termite presence, and construction styles that can conceal infestations makes the inspection an important part of due diligence for both buyers and lenders.
NPMA-33 WDI report. The standard inspection form used in Houston real estate transactions is the NPMA-33, a nationally standardized Wood Destroying Insect report. The form documents the inspector's findings regarding evidence of active wood-destroying insects, evidence of previous infestations, evidence of previous treatment, and conditions conducive to infestation. The report identifies specific areas of concern and provides photographs when possible. It must be completed by an inspector licensed through the Texas Department of Agriculture, Structural Pest Control Service.
VA loans require a WDI report. All VA-financed home purchases in the Houston area require a current WDI report. The report must be completed by a TDA/SPCS-licensed inspector and be current within 90 days of closing. If the report identifies active termite activity, treatment must be completed and documented before the loan can close. The VA does not specify who pays for the inspection, but local custom in the Houston market places the cost on the buyer.
FHA loans require a WDI report in Houston. FHA guidelines require a WDI report in areas designated as having significant termite risk. All of greater Houston, including Harris County and all surrounding counties, falls within this designation. Virtually every FHA-financed home purchase in the Houston metro requires a termite inspection as a condition of the loan.
Conventional lenders frequently request one. While not universally mandated for conventional financing, the majority of conventional lenders active in the Houston market request a WDI report as part of their standard underwriting package. Houston's reputation as a high-termite-pressure market means that lenders view the inspection as a reasonable precaution to protect the collateral value of the property.
The buyer typically pays. In Houston real estate transactions, the buyer typically pays for the termite inspection. This is the prevailing local custom, though the cost is negotiable between the parties. The inspection cost ($100 to $175 for a formal WDI report) is usually included in the buyer's closing costs.
Findings are negotiated. If the inspection reveals active termites or evidence of damage, the findings become a negotiation point between buyer and seller. The buyer may request that the seller pay for treatment before closing, provide a credit to cover treatment and repair costs, or purchase a transferable termite bond. In cases where Formosan termite damage is found, the scope of repairs can be significant and may substantially affect the negotiation. The approach depends on the purchase agreement, the severity of the findings, and market conditions.
Sellers with an active bond have a clear advantage. Homes sold with an active, transferable termite bond are at a meaningful advantage in the Houston market. The bond demonstrates ongoing professional monitoring, regular inspections, and a treatment guarantee that the buyer can assume. In a market where Formosan termites can cause thousands of dollars in damage in less than a year, an active termite bond provides substantial reassurance to buyers and their lenders. Sellers who maintain a termite bond should highlight this fact in the listing and have the bond documentation available for prospective buyers.
Why Is Houston's Termite Pressure So Heavy?
Houston consistently ranks among the highest-risk termite markets in the United States. Multiple environmental and geographic factors converge in the Houston metro to create conditions that are nearly ideal for termite colony survival, growth, and year-round foraging activity.
Hot, humid climate with no winter kill. Houston's subtropical climate provides termites with conditions that support activity throughout the entire year. The average winter low in Houston rarely drops below the mid-40s Fahrenheit, and hard freezes that reach into the soil are extremely rare. In northern states, winter freezing pushes termite colonies deeper into the soil and significantly reduces foraging activity for several months. Houston never experiences this seasonal suppression. Termite colonies remain active near the soil surface and continue foraging against foundations 12 months a year. The extended growing season means that colonies have more time to expand, produce reproductives, and establish new satellite colonies each year compared to colonies in colder climates.
Heavy clay soil retains moisture. The Houston metro sits on heavy clay soil, often called "gumbo clay," that retains water effectively. Subterranean termites require consistent soil moisture to survive, and Houston's clay soil maintains damp conditions near foundations for days or weeks after rainfall. The soil's moisture retention creates a hospitable zone around every home's foundation where termite foraging activity concentrates. The clay also expands when wet and contracts when dry, creating seasonal cracks in foundations and slabs that termites exploit as access points. This cycle of soil movement and cracking is a continuous process in the Houston climate, regularly creating new entry opportunities.
Over 50 inches of annual rainfall. Houston receives an average of approximately 50 inches of rain per year, with some years significantly exceeding that figure. This abundant rainfall maintains soil moisture at levels favorable for termite survival even during the drier months. Tropical storms and hurricanes periodically deliver rainfall totals that saturate the soil to extreme depths, creating conditions that favor rapid colony expansion in the months following these events. The combination of high rainfall and clay soil that retains that moisture creates a persistently damp soil environment that subterranean termites are adapted to exploit.
Gulf Coast proximity increases Formosan pressure. Houston's location along the Gulf Coast is directly related to the establishment and prevalence of Formosan subterranean termites in the metro. Formosan termites were introduced to the United States through Gulf Coast ports, and port cities like Houston, New Orleans, and Mobile were among the first establishment points. Houston's port activity continues to provide opportunities for new introductions of Formosan populations. The Gulf Coast climate is also the ideal habitat range for Formosan termites, which require higher moisture and temperature levels than native subterranean species. Inland Texas cities like Dallas, San Antonio, and Austin have significantly lower Formosan pressure than Houston because they lack the coastal humidity and milder winter conditions that Formosan colonies require.
Hurricane flooding displaces colonies. Houston's history of major flooding events, including Hurricane Harvey in 2017 and numerous other tropical storm events, has a direct impact on termite pressure throughout the metro. When floodwaters inundate a property, existing chemical termiticide barriers in the soil around the foundation can be diluted, displaced, or washed away entirely. The post-flood saturated soil creates ideal conditions for termite colony recovery and expansion. Homes that underwent flood damage repairs may have had new construction materials installed without corresponding termite treatment, leaving the repaired areas unprotected. The cumulative effect of repeated flooding events over decades has compromised termite protection on thousands of Houston homes, contributing to the area's overall high termite pressure.
Dense vegetation and mature trees. Houston's urban canopy is one of the densest of any major U.S. city. Mature trees, extensive landscaping, mulch beds, and dense vegetation near foundations create shade and moisture that favor termite activity. Dead wood from fallen branches, tree stumps left after removal, and railroad tie landscaping features all serve as potential colony establishment sites within foraging range of residential structures. The combination of established colonies in surrounding vegetation and the short foraging distances to adjacent foundations means that even new construction in well-maintained subdivisions is within reach of existing colonies.
When Do Termites Swarm in Houston?
Houston has two distinct termite swarm seasons, one for each major subterranean species. Knowing the timing, appearance, and behavior of each species' swarms helps homeowners identify which species may be present and respond appropriately.
Eastern subterranean termite swarms: February through May. Eastern subterranean termites typically swarm in Houston from late February through May, with peak activity in March and April. Swarms are triggered by warm, humid conditions, usually within a day or two after a warm rain when soil temperatures have reached approximately 70 degrees Fahrenheit. Eastern subterranean swarmers emerge during the daytime, usually in the late morning or early afternoon. They are dark-bodied with translucent wings of equal length, approximately 3/8 inch long including the wings. The swarm event is brief, typically lasting less than an hour. After the swarm, discarded wings are found in window sills, near doorways, and on exterior surfaces near the foundation. Finding discarded wings inside the home is a strong indicator that a colony exists within or immediately adjacent to the structure.
Formosan subterranean termite swarms: late May through July. Formosan termites swarm in Houston from late May through July, with peak activity typically in June. The timing difference from eastern subterranean swarms is significant and helps with identification. Formosan swarmers emerge at dusk, usually between 8:00 PM and 10:00 PM, and are strongly attracted to lights. This attraction to artificial light sources is one of the most distinctive Formosan swarming behaviors. Homeowners may see large numbers of winged insects swarming around porch lights, streetlights, and illuminated windows during warm evenings in late May and June. Formosan swarmers are larger than eastern subterranean swarmers, approximately 1/2 inch long including wings, and have a yellowish-brown body.
How to distinguish Formosan swarmers from eastern subterranean swarmers. The most practical ways to tell them apart are timing and behavior. Eastern subterranean swarmers appear during the daytime from February through May. Formosan swarmers appear at dusk from late May through July and are strongly attracted to lights. If you see large winged insects swarming around lights at dusk during late May or June near your foundation, they are very likely Formosan swarmers. Both species can be distinguished from flying ants by their straight antennae (ants have elbowed antennae), equal-length wings (ants have front wings longer than rear wings), and broad waist (ants have a pinched waist).
What to do if you see swarmers. If you observe termite swarmers inside your home at any time between February and July, schedule a professional inspection immediately. Interior swarmers indicate a colony within or directly beneath the structure. Collect several specimens in a sealed plastic bag and keep them for the inspector to examine. This helps with species identification, which affects the treatment approach and urgency. If the swarmers appear to be Formosan (at dusk, attracted to lights, larger body, May through July), communicate this to the inspector so they can prioritize attic and wall cavity evaluation during the inspection.

Which Houston Neighborhoods Have the Highest Termite Risk?
Termite risk in the Houston metro varies based on the age of the housing stock, construction type, soil conditions, proximity to water features, vegetation density, and treatment history. While every part of greater Houston has termite pressure, certain neighborhoods and areas consistently see higher levels of activity and more frequent infestations.
The Heights and Garden Oaks. These inner-loop neighborhoods contain a large concentration of homes built from the 1920s through the 1950s, many on pier-and-beam foundations with crawl spaces. The older construction, mature trees throughout the neighborhoods, and dense vegetation create elevated termite risk. Pier-and-beam homes in the Heights provide accessible crawl spaces where inspectors can detect mud tubes on piers and beams, which is an advantage for early detection. However, the age of these structures means that original wood framing has had decades of potential exposure, many homes have gone through periods without active termite protection, and the mature landscape creates persistent moisture and colony habitat near foundations. The Heights has documented Formosan termite activity, with carton nests found in attics and wall cavities of renovated and unrenovated homes alike.
Montrose and River Oaks. Montrose features a mix of residential ages and styles, from early 1900s bungalows to mid-century construction to recent townhomes. The older homes in Montrose share the same risk factors as Heights-era construction: pier-and-beam foundations, mature trees, and long histories of variable termite protection. River Oaks, while featuring well-maintained properties, has extensive mature landscaping and large, complex homes with significant amounts of structural wood. The heavy landscaping in River Oaks creates persistent moisture near foundations, and the larger homes have more potential entry points and more areas that are difficult to inspect without professional assistance. Both neighborhoods have confirmed Formosan termite presence.
Meyerland and Bellaire. These neighborhoods contain large numbers of homes built in the 1950s and 1960s on slab-on-grade foundations. The original pre-construction termite treatments on these homes, likely chlordane or another now-banned organochlorine, degraded decades ago. Many properties have experienced flooding during multiple events (including Hurricane Harvey), which further compromised any remaining chemical barriers in the soil. The post-Harvey rebuilds in Meyerland, where many homes were raised and reconstructed, represent a mix of risk levels. Properly rebuilt homes with new pre-construction treatment are currently protected, but that protection has a limited lifespan (5 to 10 years). Homes that were repaired rather than rebuilt may have had new construction materials installed on existing slabs without corresponding termite treatment.
Third Ward and East End. These neighborhoods east of downtown contain older housing stock with a mix of pier-and-beam and early slab construction. The proximity to the ship channel and bayous means consistently higher soil moisture levels, which supports more active termite colonies. Older homes in these neighborhoods may have limited treatment history, and the housing stock includes many properties with deferred maintenance that creates conditions favorable to termite infestation: moisture damage, wood-to-soil contact, and compromised foundations.
Spring Branch. This large area of northwest Houston contains homes primarily built in the 1960s and 1970s on slab-on-grade foundations. Like Meyerland and Bellaire, the original pre-construction treatments on these homes expired decades ago. Spring Branch has experienced flooding in recent years, and the heavy clay soil throughout the area retains moisture effectively. The neighborhood's mid-century housing stock represents a concentrated zone of properties that likely have no remaining chemical termite barrier and are relying entirely on the concrete slab, with all its cracks and penetrations, as the only physical separation between the soil and the structural wood.
Newer suburbs: Katy, Sugar Land, The Woodlands, and Pearland. These newer suburban communities generally feature more recent construction with current or recently expired pre-construction termite treatments. The lower immediate risk in these areas should not create complacency. Formosan subterranean termites have been confirmed throughout Harris County and in surrounding counties, meaning these newer communities are within the established range of the most destructive species. As pre-construction treatments expire (5 to 10 years after application), homes in these areas will need ongoing protection. Homeowners in communities built 10 or more years ago should verify their treatment status and consider establishing a termite bond. The same clay soil and high-moisture conditions present throughout the metro are present in these communities, maintaining the underlying termite pressure regardless of construction age.
What Does Treatment Cost If Termites Are Found?
If a termite inspection in Houston reveals active termite activity, the next step is treatment. Houston treatment costs reflect the area's higher-than-average termite pressure and the potential need for Formosan-specific treatment protocols.
| Treatment Method | Houston Cost | National Average | Best For |
|---|---|---|---|
| Liquid barrier treatment | $1,500 – $3,500 | $900 – $2,500 | Eastern subterranean infestations |
| Bait station system | $1,800 – $4,000 | $1,400 – $3,000 | Colony elimination, ongoing monitoring |
| Formosan-specific (liquid + bait) | $2,500 – $5,500 | Varies | Confirmed Formosan infestations |
| Spot treatment | $300 – $800 | $250 – $600 | Small, localized infestations |
Liquid barrier treatment ($1,500 to $3,500) is the most common treatment for eastern subterranean termite infestations in Houston. A technician trenches around the home's foundation perimeter and applies a liquid termiticide (typically fipronil-based or imidacloprid-based) to create a continuous chemical barrier in the soil. For slab-on-grade homes, the treatment may include drilling through concrete patios, garage slabs, and porches to treat the soil directly against the foundation. Houston's clay soil retains termiticide reasonably well, but the seasonal expansion and contraction of the clay, combined with periodic flooding, can shorten the effective lifespan compared to more stable soil types. The higher end of the Houston price range reflects the larger lot sizes and greater linear footage of many Houston homes compared to national averages.
Bait station systems ($1,800 to $4,000) use monitoring stations installed in the soil around the home's perimeter at regular intervals, typically every 10 to 15 feet. When termite activity is detected in a station, the monitoring cartridge is replaced with a slow-acting bait that workers carry back to the colony, eventually eliminating it. Initial installation includes the first year of monitoring. Annual renewal for ongoing monitoring typically runs $200 to $400 per year. Bait systems are effective against both eastern subterranean and Formosan colonies, and the ongoing monitoring component provides year-round surveillance in a market where termites are active in every season.
Formosan-specific treatment ($2,500 to $5,500) is required when Formosan subterranean termites are confirmed. Because of the massive colony size and the potential for carton nests in upper walls and attics that are independent of soil contact, treating Formosan infestations often requires both a liquid barrier in the soil (to intercept soil-based foraging) and direct treatment of carton nests and gallery systems within the structure. This may involve injecting foam termiticide into wall cavities, removing and treating carton nests in the attic, and installing bait stations around the perimeter for ongoing colony suppression. The combined approach is more expensive but necessary because a liquid barrier alone may not reach Formosan colonies that have established moisture-retaining carton nests above ground.

What Are Termite Bonds in Houston?
A termite bond is an ongoing service agreement between a homeowner and a pest control company that provides continuous termite protection. Termite bonds are standard practice in the Houston market, and given the year-round termite pressure from both native and Formosan species, they represent the most practical approach to long-term termite management.
Annual cost: $150 to $400 per year. The annual renewal cost depends on the size of the home, the treatment provider, the type of treatment installed (liquid barrier or bait system), and whether the bond includes repair coverage. A basic bond that covers annual inspections and re-treatment if termites are found typically runs $150 to $250 per year. A premium bond that also covers structural repair costs for termite damage that occurs during the bond period typically runs $250 to $400 per year.
What the bond includes. A standard termite bond in the Houston market includes an annual professional inspection of the property, guaranteed re-treatment at no additional cost if termites are found during the annual inspection or at any other time during the bond period, and documentation of inspection results and any treatment performed. Premium bonds add coverage for repair of structural damage caused by termites during the bond period, typically up to a specified coverage limit.
Transferability. Most termite bonds in Houston are transferable to a new homeowner when the property is sold. The new owner assumes the bond by paying the next annual renewal. A transferable bond with a documented treatment and inspection history is a significant selling point in the Houston real estate market. It provides the buyer with immediate termite protection, a professional relationship with a pest control company, and documented evidence of ongoing monitoring. Sellers who maintain a termite bond should include the bond documentation in their listing materials.
Bond vs. no bond: the math. A termite bond costs $150 to $400 per year. A single termite treatment if termites are discovered without a bond costs $1,500 to $5,500 depending on the species and severity. Structural repair costs from undetected termite damage can reach $5,000 to $15,000 or more. In a market where every home is within foraging range of active termite colonies and Formosan termites can cause significant structural damage in six months, the annual bond cost is a practical form of ongoing protection. For more information on whether termite damage is covered by insurance, see our termites and insurance guide.
Frequently Asked Questions
Get a Termite Inspection in Houston
A termite inspection is one of the most important home maintenance steps for Houston homeowners. At $75 to $200 for an independent inspection, the cost is a fraction of what treatment costs if an infestation is found ($1,500 to $5,500), and it is negligible compared to the structural repair costs that result from infestations that go undetected. Houston's combination of year-round warmth, heavy clay soil, abundant rainfall, and established Formosan termite populations creates a termite environment that is among the most aggressive in the country.
The presence of Formosan subterranean termites makes Houston's termite risk qualitatively different from most other Texas cities. A Formosan colony can cause structural damage in months, not years, and their ability to build carton nests in attics and walls means that infestations can develop in areas that homeowners would never think to check. Professional inspections that include thorough attic evaluation are essential in the Houston market for this reason.
If you are buying or selling a home in Houston, a WDI report is required for VA and FHA financing and is requested by most conventional lenders. If you are a current homeowner without an active termite bond, scheduling an inspection is the first step toward establishing ongoing protection. The best time to schedule is before swarm season begins in February, though inspections are valuable and available year-round because Houston termites do not go dormant.
