The short version
In Texas, termite control means dealing with eastern subterranean and Formosan termites. Swarms start as early as January in South Texas and continue through May in the Panhandle. If you see mud tubes, hollow wood, or winged termites, a professional inspection is your next step.
- Termite damage is not covered by most homeowners insurance.
- Subterranean termites swarm in spring; Formosan termites are a major threat along the Gulf Coast.
- Professional treatment costs $1,200–$3,000; fumigation can exceed $8,000 for severe cases.
- DIY solutions are rarely effective for established colonies; professional inspection is key.
- Texas requires termite inspections (WDO/WDI) for many real estate transactions.
- A homeowner putting off a termite quote should know that 75% of professionals in Pest Control Technology (PCT) magazine's 2025 termite market report (about 145 respondents) expected to raise prices in 2025.
For Texas homeowners, real estate agents, property managers, and landlords who need accurate, actionable information about termite prevention, detection, and treatment. If you're buying or selling a home, you'll learn about required inspections and how to spot red flags. If you manage rental properties, you'll understand how to protect your assets and tenants. And if you're a homeowner worried about that mud tube on your foundation, you'll find clear steps to take.
What to look for
The most common species in Texas are the Eastern subterranean termite and the Formosan subterranean termite. Subterranean termites live in underground colonies and build mud tubes to reach food sources above ground. Formosan termites are especially aggressive, with colonies that can number in the millions—they are a major concern along the Gulf Coast, from Houston to Beaumont. Unlike ants or roaches, termites don't just scavenge; they digest cellulose from wood and paper, which means your home's structure is literally their meal. Most homeowners insurance policies exclude termite damage, so you bear the full cost of repairs. The problem is compounded by the fact that many homeowners don't realize they have termites until visible damage appears—like sagging floors, hollow-sounding wood, or buckling paint. By then, the cost of repair can dwarf the cost of prevention.
- 1Mud tubes on foundation walls, floor joists, or crawl spaces (pencil-sized or larger).
- 2Discarded wings near windows, doors, or light fixtures (swarmers shed wings after mating).
- 3Hollow-sounding wood when tapped (termites eat wood from the inside out).
- 4Frass (termite droppings) that look like small, wood-colored pellets or sawdust.
- 5Blistered or dark areas on wood flooring or walls (moisture from termite activity).
- 6Tight-fitting doors or windows that become hard to open (warped wood due to moisture).
- 7Small holes in drywall or wood with a powdery residue.
Why it’s worth acting soon
- Structural damage to load-bearing beams, joists, and walls, leading to costly repairs (often $3,000–$10,000+).
- Reduced home value and difficulty selling without a termite bond or clearance letter.
- Spread of infestation to neighboring properties or other parts of the home.
- Increased treatment costs: early intervention costs $1,200–$3,000, while advanced infestations may require fumigation ($2,000–$8,000) or extensive construction.
- Health concerns: termite activity can create moisture that promotes mold growth.

Liquid soil treatment
Quoted after inspection
A professional applies termiticide to the soil around your foundation, creating a continuous barrier that kills termites as they cross. This is a common choice for new construction and existing homes.
- Time
- 5 years or more
- Best for
- Homes with accessible soil around the foundation and a desire for long-lasting protection.
Bait station system
Quoted after inspection
Stations are placed in the ground around the home and monitored regularly. Termites feed on the bait and share it with the colony, reducing its population over time.
- Time
- Ongoing maintenance required
- Best for
- Homes where a full liquid treatment is impractical or as a complementary approach.
Wood treatment
Quoted after inspection
For localized infestations, a professional may treat wood directly with a borate-based product. This is often used in crawlspaces or for exposed framing.
- Time
- Varies
- Best for
- Spot treatments of accessible infestations, often used with other methods.
Fumigation
Quoted after inspection
Whole-structure fumigation is rarely needed for subterranean termites, as they live in the soil. It may be used if drywood termites are also present, which is uncommon in Texas.
- Time
- 2-3 days
- Best for
- Severe, widespread infestations, especially when drywood termites are involved.

A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.The two termites that matter in Texas.
Texas A&M identifies the eastern subterranean termite and the Formosan subterranean termite as the two economically important species. The eastern subterranean is found throughout the state and builds colonies in soil, often containing up to 250,000 workers. The Formosan, established along the Gulf Coast, is more aggressive and can chew through wood faster. Knowing which species you have influences the treatment approach. Formosan colonies are larger and may require more intensive methods. A professional inspection can identify the species based on swarmers or soldier characteristics.
termites activity by season.
The most useful first step in Texas is to note where you have seen termites and when they appear, because that timeline is what lets a provider focus on the right area instead of treating the whole property. In Texas, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure usually turns up the conditions that are letting them in. Scheduling before the busy stretch, rather than after it, tends to mean faster service and a more accurate quote, and a local provider can point out the conditions that matter most in Texas.
Crawl spaces are where termites usually get in. Joists, piers and the sill plate should all get a close look.A month-by-month timeline for Texas.
In South Texas, swarmers appear as early as January and February. In the central regions, watch for activity in March and April. The Panhandle sees swarms later, in April and May. After swarming, termites may be less visible, but they continue to feed. Spring is the peak season for homeowners to spot signs. Regular inspections in late winter and early spring can catch infestations before they cause significant damage. Even in the heat of summer, subterranean termites remain active, especially in moist soil.
What the first visit looks like.
A termite inspection typically takes 30 to 60 minutes. The technician will check the exterior for mud tubes, wood-to-soil contact, and moisture issues. Inside, they'll probe baseboards, door frames, and crawlspaces. They may use a moisture meter or infrared camera. After the inspection, you'll receive a report of findings and a treatment recommendation. If termites are found, the company will explain your options and provide a quote. Ask questions about the treatment plan, warranty, and maintenance.
What affects the price in Texas homes.
The cost of termite treatment in Texas varies with home size, construction type, and the extent of the infestation. Slab homes require drilling to reach the soil, which adds labor. Crawlspace homes are often easier to treat. Older homes may have more wood-to-soil contact, increasing the workload. Geographic location also plays a role. Treatment in Houston may cost more than in rural areas due to higher labor rates. The type of treatment, liquid vs. bait, also affects the price. Get at least three quotes to compare.
Prevention for Texas housing styles.
Texas homes range from historic bungalows to modern stucco houses. Older homes often have wood foundations or additions with direct soil contact. Newer slab homes are also at risk if soil settles and creates gaps around pipes. Regardless of style, the same principles apply: keep wood away from soil, fix moisture problems, and inspect regularly. For homes with crawlspaces, ensure proper ventilation and a vapor barrier. For slab homes, seal expansion joints and utility penetrations.
Renters, landlords, and who pays.
In Texas, landlords are generally responsible for maintaining a habitable dwelling, which includes addressing termite infestations. Renters should report any signs of termites promptly. Landlords should have an annual inspection to protect their property. If you're a renter, you may not be responsible for treatment costs, but you should keep a record of the issue and notify your landlord by email or text. For landlords, treating termites is an investment in your property's value.
What affects the price
- Size of the home (square footage and number of stories).
- Type of termite (subterranean vs. drywood; Formosan may require more aggressive treatment).
- Extent of infestation (localized vs. whole-structure).
- Accessibility of the treatment area (crawl spaces, slab construction, etc.).
- Geographic location within Texas (Gulf Coast areas may have higher pressure).
- Warranty options (renewal fees vs. one-time).
- Need for repairs or wood replacement before treatment.

What is your biggest concern about termites?
When to call for help
If you see any signs of termites—mud tubes, swarmers, damaged wood, or frass. a licensed pest control professional immediately. Do not attempt to treat an active infestation yourself; over-the-counter sprays are rarely effective and can scatter the colony, making professional treatment harder. Professionals have the training and equipment to identify the species, locate the colony, and apply the correct treatment.
What you can do yourself
DIY termite control is generally ineffective for established colonies. While you can take preventive steps like reducing moisture around your foundation and storing firewood away from the house, once termites are active, you need professional-grade termiticides and application methods. Liquid soil treatments require precise trenching and injection to create an uninterrupted barrier—something DIYers rarely achieve. Bait systems require ongoing monitoring to ensure stations are being fed on. For drywood termites, spot treatments can work for localized infestations, but fumigation is often needed for full eradication. The cost of a professional treatment ($1,200–$3,000) is a fraction of the cost of major repairs (often $5,000–$10,000+). Plus, professional services come with a warranty and the peace of mind that the job is done right.
Where you live matters
Swarming typically occurs from March to May after a warm rain. The drier climate in West Texas (El Paso, Midland-Odessa) reduces termite pressure, but subterranean termites can still be found in irrigated areas and near wood sources. In North Texas (Amarillo, Lubbock), cold winters slow termite activity, but colonies survive deep underground. Regardless of location, any structure with wood-to-soil contact or moisture problems is at risk. For city-specific information, search for termite control guides tailored to your metro area. Texas is a large state with diverse climates, and termite pressure varies significantly by region. In the humid Gulf Coast area (Houston, Galveston, Beaumont, Corpus Christi), termites are active year-round, with Formosan subterranean termites posing a serious threat. These areas see multiple swarming events from spring through early summer. Homeowners here should consider ongoing bait systems and annual inspections. In Central Texas (Austin, San Antonio, Dallas-Fort Worth), Eastern subterranean termites are the main concern.
Simple ways to keep termites away
- Remove wood-to-soil contact: Keep mulch, lumber, and firewood away from your foundation.
- Fix leaks and drainage issues to reduce moisture around your home.
- Ensure gutters and downspouts direct water away from the foundation.
- Seal cracks in your foundation and around utility lines.
- Inspect crawlspaces and basements regularly for mud tubes.
- Replace wood that has been damaged by water or termites.
- Store firewood off the ground and at least 20 feet from the house.
- Consider a termite bond or annual inspection with a licensed company.

Questions people ask
How do I know if I have termites or ants?
Termite swarmers have four wings of equal size, a straight waist, and straight antennae. Ants have elbowed antennae, a pinched waist, and front wings longer than hind wings. Also, termites leave mud tubes and frass; ants do not.
Does homeowners insurance cover termite damage?
No. Most standard homeowners insurance policies exclude termite damage because it is considered preventable. You will need to pay for treatment and repairs out of pocket.
How long does a termite treatment last?
Liquid soil treatments typically last 5–10 years. Bait systems require ongoing monitoring, with bait stations replaced as needed. Fumigation is a one-time treatment but does not prevent reinfestation.
Can I treat termites myself?
DIY treatments are rarely effective for established colonies. Over-the-counter sprays may kill some termites but often scatter the colony, making professional treatment harder. For prevention, you can reduce moisture and remove wood debris, but active infestations require professional-grade products and application.
What is a termite bond?
A termite bond is a renewable service contract with a pest control company that includes annual inspections and treatment if termites are found. It provides ongoing protection and often includes a warranty that covers retreatment. Many lenders require a bond for certain loan types.
How do I prepare for a termite inspection?
Ensure the inspector has access to all areas: crawl spaces, attics, basements, and the perimeter. Remove stored items from corners and clear debris from the foundation. Point out any previous water damage or visible signs. The inspection is non-invasive, so no special preparation is needed beyond clearing access.
What is the best time of year for termite treatment?
Treatment can be done year-round, but spring (March-May) is ideal because termites are most active and swarmers are visible.
Do most pest control companies treat existing homes for termites?
In Texas, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In Texas, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
