Termites in Central Texas: Silent Damage, Serious Consequences

Termites destroy more U.S. property value each year than fires, floods, and windstorms combined. The U.S. Department of Agriculture estimates annual termite damage at over $5 billion — and the vast majority of that damage is not covered by standard homeowner’s insurance, because termite damage is classified as a maintenance issue, not a disaster.

Central Texas sits in what the USDA classifies as a “heavy” to “very heavy” termite activity zone. If you own a home in Round Rock, Georgetown, Cedar Park, Kyle, or anywhere in between, termites are a genuine, ongoing risk — whether or not you have ever seen one. Here is what every Central Texas homeowner needs to know.

The Primary Threat: Subterranean Termites

Texas is home to several termite species, but the one responsible for the overwhelming majority of residential damage in Central Texas is the Eastern Subterranean Termite (Reticulitermes flavipes). These termites live in underground colonies that can number in the hundreds of thousands to over a million workers. They require constant contact with moisture and soil, which is why they build mud tubes — pencil-wide tunnels of soil and saliva — to travel from their underground colonies to the wood in your home without drying out.

Formosan termites (Coptotermes formosanus), a more aggressive invasive species, are also established in Texas and spreading. Formosan colonies can be vastly larger than native subterranean colonies and cause damage at a significantly faster rate. If you are in the Houston or Gulf Coast region this is a higher concern, but Formosans are documented in Central Texas and are worth knowing about.

Identification: What Termites Look Like

Most homeowners never see active worker termites — they stay hidden inside wood and underground. The most common sighting is a termite swarm: winged reproductive termites (alates) that emerge in spring, typically after warm rains, to mate and establish new colonies. Swarmers are often mistaken for flying ants.

Here is how to tell them apart:

• Antennae: Termites have straight, beaded antennae; ants have elbowed antennae
• Waist: Termites have a thick, uniform waist; ants have a narrow, pinched waist
• Wings: Both pairs of termite wings are equal length; ant rear wings are shorter than front wings
• Coloring: Termite swarmers are typically dark brown to black with pale wings

If you find discarded wings near windowsills or doors, that is a strong indicator of a recent swarm — and potentially an established colony nearby.

Why They Are So Destructive

The damage model with termites is fundamentally different from most other pests. Termites work inside wood, consuming the cellulose while leaving the outer surface intact. A wall stud, floor joist, or door frame can be almost completely hollowed out with no visible external indication until the damage is severe enough to cause sagging, buckling, or structural failure.

A mature subterranean termite colony can consume approximately one pound of wood per day. This sounds modest, but over months and years of undetected activity, the structural impact is substantial. Homes with pier-and-beam foundations, wood decks in contact with soil, or cellulose-based landscaping materials (mulch, wood chips) against the foundation are at elevated risk.

Warning Signs of Termite Activity

• Mud tubes on foundation walls, pier caps, or in crawlspaces — the clearest sign of subterranean termite activity
• Wood that sounds hollow when tapped
• Paint that bubbles or blisters without moisture exposure — can indicate termites working underneath
• Doors or windows that suddenly stick — wood distortion from termite damage can cause frame warping
• Frass near wood trim, baseboards, or sills — this is drywood termite excrement (small, pellet-like), less common in Central Texas but present
• Visible swarmers or discarded wings, especially near light sources in spring

Prevention: What Actually Helps

• Eliminate wood-to-soil contact at the foundation — this includes wood trim, siding, decking, and stored lumber
• Keep mulch and wood chips at least 6 inches away from the foundation
• Fix leaks promptly — subterranean termites are drawn to moisture
• Ensure good drainage away from the foundation
• Do not store firewood against the house
• Have visible crawlspace and attic areas inspected annually

Treatment Options

Professional termite treatment in Central Texas typically involves liquid soil treatments (termiticides applied around and under the foundation), bait systems (stations placed in the soil that deliver toxicant back to the colony), or a combination of both. The right approach depends on your home’s construction type, the extent of activity, and the species involved.

There are no effective consumer-grade termite treatments that approach what professional products accomplish. Termite control is one of the pest problems where professional intervention is not just recommended — it is effectively the only path to genuine elimination.

When to Call a Professional

The honest answer: you should have a termite inspection if you have not had one in the past two years and you own a home in Central Texas. This is true even if you have never seen a termite — the damage is happening inside walls you cannot see.

If you see mud tubes, swarmers, or any of the warning signs above, contact a pest control professional immediately. The cost of treatment is a fraction of the cost of structural repairs, and the difference between a contained infestation and significant damage is often just time.
