Termites in Texas: Types, Warning Signs, and What to Do

Short Answer

Texas is overwhelmingly a subterranean termite state. Native subterranean termites live in the soil, reach a structure from the ground, and often leave mud tubes. The invasive Formosan subterranean termite is concentrated along the Gulf Coast and in major metros, and it deserves faster professional attention when suspected. Drywood termites occur across the state, most heavily near the coast, and live inside dry wood rather than in soil.

The practical first step is to identify the evidence and the termite group before choosing a treatment. Use the comparison below, then follow the matching route in our termite treatment decision guide.

Subterranean firstThe eastern subterranean termite is the most commonly encountered species, and subterranean termites are the main statewide structural concern.
Timing shifts by regionSwarming can begin in January in South Texas but not until April or May in the Panhandle.
Identification firstSoil treatments, baits, spot treatments, wood removal, and moisture repair solve different problems.

Texas Termites at a Glance

Scroll the table sideways to see every column.

Group Where it is found Strongest clues Usual next route
Native subterranean Found throughout Texas; the broad statewide baseline, more prevalent toward the coast Mud tubes, soil-linked entry, swarmers or shed wings, damage that often follows the grain and may contain soil Professional inspection; soil treatment or a monitored bait system depending on the structure and infestation
Formosan subterranean Concentrated on the Gulf Coast and in major metropolitan areas; reported in more than 30 counties and still spreading Subterranean signs plus large evening swarms at lights, possible carton material in voids, tree involvement, or wider hidden activity Faster professional assessment and a plan designed for colony scale, colony access, and the structure
Drywood Found throughout Texas, with the highest concentrations along the Gulf Coast Hard six-sided pellets, kick-out holes, localized galleries, swarmers or shed wings; no soil mud tubes Thorough inspection; localized removal or labeled spot treatment when truly limited, or structural fumigation for broader or uncertain infestations

This table routes the inspection; it does not confirm a species. For a closer side-by-side explanation, see subterranean vs. drywood vs. dampwood termites. Damp, decaying wood is primarily a moisture problem to correct rather than a distinct Texas treatment target.

Why Your Texas Location Matters

Texas is large enough that termite pressure and swarm timing shift noticeably from one region to another. County records reflect sampling and reporting as much as biology, so treat regional notes as a risk orientation rather than proof that a species is present or absent at one address.

East and Gulf CoastHouston, Galveston, Beaumont, Port Arthur, and Orange see the highest pressure: heavy native subterranean activity, the strongest Formosan concentration, and the densest drywood records.
Central TexasAustin, San Antonio, and Waco are subterranean-dominant, with frequency decreasing away from the Gulf. Formosan termites are present in several metro counties.
North Texas and DFWDallas, Collin, Denton, Tarrant, and Rockwall are subterranean-dominant, and Formosan termites are confirmed in several DFW-area counties.
West TexasGenerally lower pressure than the Gulf Coast, with arid-land subterranean termites present and drywood termites in some areas.

A winged termite that flies indoors may have come from outside; indoor emergence, repeated activity, pellets, tubes, or damaged wood makes a structural inspection more important. Used and antique furniture should be inspected for pellets, holes, or damage before it is brought indoors, since drywood termites can travel in wood rather than through the yard.

Warning Signs and What They Can Tell You

Mud tubes

Soil-colored tubes on foundations, walls, piers, plumbing penetrations, or hidden joints strongly support a subterranean route. A tube can remain after activity stops, so its appearance alone does not prove that the colony is active today. See termite mud tubes vs. old damage.

Frass or pellets

Drywood termites push dry, hard, six-sided pellets through small kick-out holes. Sawdust, ant debris, and beetle frass can look similar at a glance, so use our droppings vs. frass guide before assuming the source.

Swarmers and discarded wings

Indoor swarmers or repeated piles of wings near the same window, door, vent, or light deserve prompt inspection. Outdoor swarmers near a home show that termites are in the area but do not automatically prove an indoor infestation.

Damaged, hollow, or soft wood

Subterranean damage often follows the wood grain and may contain soil. Drywood galleries can cross the grain and remain hidden inside apparently sound wood. Soft, wet, or decayed wood points to a moisture problem that should be corrected. Visible damage cannot show how far hidden damage extends.

When Do Termites Swarm in Texas?

Texas does not have one reliable “termite season.” Swarming timing can help orient an inspection, but species, weather, region, and indoor conditions all shift the calendar.

Jan-May (by region)Native subterranean termites swarm in spring and early summer during the day. Swarming begins in South Texas in January and February; in the Panhandle it may not occur until April and May.
May-JuneFormosan subterranean termites typically swarm at night and are attracted to lights.
Late Aug-early SepDrywood termite reproductives commonly develop wings and swarm in this window.
IndoorsSwarmers appearing indoors near lights or windows can fall outside the expected outdoor window and often indicate activity within the structure.

Month and time of day are supporting clues, not a species test. Preserve a useful specimen when possible: winged reproductives (alates) and soldiers are generally more informative than workers.

Why Formosan Termites Need Faster Assessment

The Formosan subterranean termite is an invasive Coptotermes species. It follows the subterranean treatment route, but its risk profile is different from an ordinary one-point household clue. Formosan colonies can grow far larger than native colonies, may involve trees, and can build moisture-holding carton material in structural voids. In Texas they are concentrated on the Gulf Coast and in major metros, but they are reported in more than 30 counties and continue to spread.

That does not mean every evening swarm is Formosan or that every suspected sighting signals immediate structural failure. It means an indoor swarm, active tubes, carton material, tree activity near the structure, or widespread hidden damage should move the case toward an experienced licensed inspection. Read the dedicated Formosan termite guide for the identification limits and professional threshold.

Get a Licensed Inspection Promptly If

  • live termites, swarmers, or repeated piles of wings appear indoors;
  • mud tubes enter framing, walls, flooring, or other structural areas;
  • pellets keep returning after careful cleanup;
  • damage is hidden, extensive, soft, sagging, or possibly structural;
  • Formosan termites are plausible in your area;
  • a real-estate transaction, fumigation, or a repair warranty is involved;
  • you cannot confidently distinguish termite evidence from a look-alike.

A photo can help with triage, but it cannot establish colony location, activity level, or structural severity.

Treatment Paths Depend on the Termite Type

Subterranean

Professional liquid soil treatments and monitored bait systems are the main paths. Construction, foundation access, soil conditions, entry points, prior treatments, and the confirmed species affect the choice.

Compare the methods in termite treatment types and bait stations vs. liquid treatment.

Formosan

The route is still subterranean control, but colony scale, trees, hidden carton nests, and contract coverage make experienced professional planning more important. Do not rely on a single retail spot treatment.

Drywood

When an infestation is genuinely limited and accessible, the plan may involve removing infested wood or furniture or using a labeled localized treatment. Multiple, hidden, inaccessible, or uncertain colonies may lead to structural fumigation.

Fumigation is regulated professional work, not a DIY procedure.

Moisture-damaged wood

Fix roof, plumbing, drainage, or other moisture sources; dry the area; and repair or replace wood that is too damaged or decayed. Moisture correction matters, but it does not reverse existing structural damage.

Safety boundary: this guide does not provide pesticide mixing ratios, trench dimensions, drilling layouts, application volumes, or instructions that replace a product label. The current label, the structure, and Texas rules govern any treatment. No method is universally best.

How to Choose a Termite Company in Texas

In Texas, structural pest control — including termite inspection and treatment — is regulated by the Texas Department of Agriculture through its Structural Pest Control Service (SPCS), not by TDLR. A business must hold a current SPCS license, and termite work is performed under the Termite control category. Termite control and structural fumigation are separate license categories.

  1. Verify the company and credentials. Confirm that the business holds a current SPCS license and has a certified applicator in the Termite category. Ask whether the person performing the work is a certified applicator, licensed technician, or registered apprentice working under the required supervision.
  2. Require an inspection-based recommendation. A quote based only on square footage does not explain the organism, evidence, access, or treatment scope.
  3. Read the written contract before treatment. Understand what is being treated, how, and what happens if activity continues.
  4. Confirm exactly what is covered. The contract should identify the organism, say whether Formosan termites are covered, state whether treatment is included, and disclose any spot-treatment limitation.
  5. Ask how the warranty works. Ask what the warranty actually covers, how much annual renewal costs, and whether it transfers to a new owner if you sell.
  6. Understand conditions that can affect coverage. Moisture, leaks, wood-to-ground contact, inaccessible areas, additions, excavation, or untreated portions of the structure may matter.
  7. Know your cancellation right. For a covered door-to-door or home-solicitation sale, Texas law gives you three business days to cancel under the Texas Business & Commerce Code. This is a general consumer protection, not a termite-specific rule.

Use our full checklist of questions to ask a termite company when comparing written proposals, and weigh professional versus self-treatment tradeoffs in DIY vs. professional termite treatment.

Buying or Selling a Home: The Texas WDI Report

When a wood-destroying insect inspection is done for a Texas real-estate transaction, it is recorded on the state’s official form, the SPCS/T-5 Wood Destroying Insect Report. Texas does not require an inspection on every sale, but when a report is prepared for a transaction it must be on this official form, and it can only be completed by a certified applicator or technician licensed in the termite category.

It helps to know what the report is and is not:

  • It is a visual inspection of accessible areas on a single day. Inaccessible areas — low crawl spaces, areas behind stored items, ducting, or wall coverings — are excluded, so a clean report is not a guarantee that no hidden activity or damage exists.
  • It reports insect evidence — active infestation, evidence of previous activity, visible damage, and conducive conditions — not an engineering opinion on whether framing needs replacement.
  • It is not a warranty. Our termite bond guide explains how a continuing service agreement differs from a one-time inspection report.
  • A WDI report may be requested by a buyer or lender; loan-specific requirements vary.

If a treatment contract or warranty is in effect, the report notes it, and the warranty and treatment diagram are typically attached. Compare written proposals with our questions to ask a termite company.

What Does Termite Treatment Cost in Texas?

There is no responsible single Texas price. The main cost drivers are the termite group, the extent and accessibility of the infestation, foundation and construction details, localized versus whole-structure work, monitoring and renewal terms, and whether the contract includes retreatment only or repair protection.

Use the national ranges in our termite treatment cost guide for orientation, then compare multiple written Texas proposals line by line. A lower headline price may cover less area, exclude Formosan termites, omit monitoring, or provide different warranty protection.

What to Do Next

  1. Document the evidence. Photograph tubes, pellets, wings, insects, and damaged areas without tearing open more of the structure. Our termite inspection tools guide covers what helps.
  2. Note where and when it appeared. Indoor versus outdoor location, repeated evidence, moisture, and time of day help route the inspection.
  3. Preserve a specimen when possible. Winged reproductives and soldiers are more useful than workers for identification.
  4. Use the decision guide. Follow the termite treatment decision tree to separate monitor, inspect, professional, and urgent routes.
  5. Get a licensed inspection when the evidence is active, hidden, structural, Formosan, or uncertain.

Bottom Line

Texas is primarily a subterranean termite state, with Formosan termites raising the stakes along the Gulf Coast and in major metros, and drywood termites found statewide but concentrated near the coast. Mud tubes point toward subterranean termites; hard pellets point toward a drywood route; persistently wet wood is a moisture problem to correct; and suspected Formosan activity lowers the threshold for professional help. Identify the group, verify the company and contract, and choose the treatment only after the evidence and structure have been assessed.
