5 Warning Signs You Have Termites in Your Home

Termites are often called "silent destroyers" because they can feed on the structural wood in your home for months or even years before you notice any signs. In North Texas, subterranean termites are the most common species, and Rockwall, TX homeowners are particularly at risk due to our clay-rich soils and warm climate. Knowing what to look for can mean the difference between catching an infestation early and facing thousands of dollars in repair costs.

Here are the five warning signs every North Texas homeowner should know.

1. Mud Tubes on Your Foundation

Subterranean termites build mud tubes, also called shelter tubes, to travel between their underground colony and the wood they are feeding on. These tubes are made of soil, wood particles, and termite saliva. They are typically about the width of a pencil and can be found on foundation walls, in crawlspaces, along plumbing pipes, and on other surfaces that connect the ground to your home.

Mud tubes are one of the most definitive signs of a termite infestation. If you see them on or near your foundation in Rockwall or anywhere in North Texas, do not disturb them. Instead, call a pest control professional for an inspection. Breaking the tubes does not stop the termites; they will simply build new ones.

2. Discarded Wings Near Windows and Doors

When termites swarm, the reproductive members leave the colony to find mates and start new colonies. After landing, they shed their wings. You may find small piles of translucent, equal-sized wings on windowsills, near doorframes, in light fixtures, or along the foundation.

In the North Texas area, termite swarms typically occur from March through May. If you find discarded wings inside your home, it could mean a colony has already established itself in or near your structure. This is a sign that demands immediate professional attention.

3. Hollow-Sounding or Damaged Wood

Termites consume wood from the inside out, leaving a thin shell of timber or paint on the surface while hollowing out the interior. If you tap on a wooden surface such as a door frame, baseboard, or window sill and it sounds hollow or papery, termites may be feeding inside.

In some cases, you may notice wood that crumbles easily when probed, or you might see maze-like patterns in the grain of exposed wood. Blistering or bubbling paint can also indicate termite activity underneath the surface. Many Rockwall homeowners discover termite damage during renovation projects when they remove drywall or flooring and find the underlying wood structures have been compromised.

4. Frass (Termite Droppings)

Drywood termites, while less common than subterranean termites in North Texas, produce distinctive droppings called frass. These tiny, pellet-shaped droppings are often found in small piles near wooden structures and look similar to sawdust or coffee grounds.

If you find small piles of what appears to be fine sawdust near baseboards, door frames, or wooden furniture, do not sweep it away without investigating further. This could be evidence of termite activity that requires professional treatment.

5. Doors and Windows That Stick

While sticking doors and windows are common in North Texas due to our expansive clay soils shifting foundations, they can also be a sign of termite damage. When termites feed on the wood framing around doors and windows, the frames can warp and swell, making them difficult to open or close.

If you notice that doors or windows that previously worked fine are suddenly sticking, and especially if you notice this in combination with any of the other signs listed above, it is worth having a termite inspection. Buckled or cracked wood around door and window frames is another related indicator.

What to Do If You Spot These Signs

If you notice one or more of these warning signs, the most important step is to contact a licensed pest control professional as soon as possible. Do not attempt to treat termites yourself, as over-the-counter products are ineffective against established colonies and can actually make the problem harder to diagnose by scattering the termites.

• Do not disturb mud tubes or damaged wood
• Collect any winged insects or wings you find in a plastic bag for identification
• Take photos of any damage or evidence you see
• Schedule a professional inspection immediately
• Ask about treatment options including liquid barriers and bait station systems
