Owning a home in Central Texas comes with many perks, but it also means sharing the landscape with some of the most destructive insects in the country. In the Austin area, homeowners mainly deal with two very different types of wood-destroying pests: drywood termites and Formosan subterranean termites.

Detecting these quiet invaders early is the best way to prevent significant structural issues. By knowing what to look for, you can protect your property and your peace of mind before a small problem turns into a major project.

Understanding the Difference Between the Two

Not all termites behave the same way, which is why early detection starts with knowing which one might be visiting. In Travis, Williamson, and Bell Counties, the habits of drywood and Formosan termites are almost opposites. One lives entirely inside your wooden structures, while the other travels back and forth from the soil.

• Drywood Termites: As their name suggests, these insects live in dry, sound wood. They do not need contact with the soil and get all their moisture from the wood they eat.
• Formosan Termites: These are a "super" version of subterranean termites. They live in massive underground colonies and build mud tubes to reach the wood in your home.
• Dietary Habits: Both types eat cellulose, which is found in wood, paper, and cardboard, but Formosans eat much faster because their colonies are so much larger.

Because their lifestyles differ, the signs they leave behind are different. Checking for both types ensures you are covering all your bases when inspecting your home.

Signs of Drywood Termites: Look for the Pellets

Drywood termites are patient. They can live inside a piece of furniture or a structural beam for years without being noticed. Because they live inside the wood, they need to keep their tunnels clean. To do this, they kick their waste out through tiny "kick-out" holes. This waste is one of the most common signs that you might need professional termite control.

• Frass: These are tiny, sand-like pellets that are often found in small piles under infested wood. They are usually hexagonal in shape and can be various colors depending on the wood the termites are eating.
• Kick-out holes: Look for tiny, pin-sized holes in wood surfaces, often sealed with a bit of "cement" made by the termites.
• Hollow wood: When you tap on a wooden beam or window frame, it shouldn't sound like a drum. If it sounds hollow, termites may have eaten the interior.

Drywood termites are common in attic rafters, window frames, and even wooden picture frames. If you find a mystery pile of "sand" on a windowsill, do not just sweep it away—it could be the early warning sign you need.

Detecting Formosan Termites: Follow the Mud

Formosan termites are aggressive and can cause damage much faster than other species. Because they are subterranean, they must stay moist to survive. If they need to cross a non-wood surface—like your concrete foundation—they build protected tunnels made of mud and saliva. These tunnels are a strong indicator that you should consider broader pest control options for your property.

• Mud tubes: Look for pencil-thick tubes running up your foundation, in crawlspaces, or even hanging from floor joists.
• Moisture bubbles: Formosans sometimes introduce so much moisture into a wall that the paint begins to bubble or peel, appearing as water damage.
• Cardboard-like material: In some cases, these termites create "carton," a hard, sponge-like material made of soil and chewed wood, inside wall voids.

Since Formosan colonies can contain millions of members, they can work through wood quite quickly. Checking your foundation and any wood-to-ground contact points once a month is a great habit for Austin homeowners.

The Warning Sign of a Swarm

One of the most obvious signs of a termite presence is a "swarm." This happens when a mature colony sends out winged termites to start new colonies. In Central Texas, this usually happens in the spring or early summer, often after a warm rain. Seeing these insects—or just their discarded wings—is a clear signal that a colony is nearby.

• Identify the wings: Termite wings are all the same length and are translucent. Ant wings, by contrast, are different lengths and have more visible veins.
• Check light sources: Swarmers are attracted to light, so you might find wings on windowsills or around outdoor porch lights.
• Time of day: Formosan termites are famous for swarming at night, while many other types swarm during the day.

Finding wings inside your home usually means the insects have already found a way in. If you see wings only outside, it is a reminder that the environment is active, and it is time to be extra vigilant about your home's exterior.

Early Detection Maintenance Tips

You don't have to wait for a swarm to protect your home. There are several things you can do around your property in Travis or Bell County to make it less inviting for termites. These maintenance steps help reduce the moisture and food sources that termites crave.

• Keep wood away from soil: Ensure there is a gap between your siding and the dirt or mulch in your garden.
• Direct water away: Make sure downspouts carry rainwater at least 3 feet from your foundation to prevent damp soil.
• Remove old debris: Stumps, fallen branches, and old cardboard boxes in a crawlspace are like magnets for subterranean termites.

By keeping your home's perimeter dry and clear, you make it much harder for Formosan termites to establish a path to your structure. Similarly, keeping your attic well-ventilated helps prevent the wood from becoming soft enough for drywood termites to easily inhabit.
