Living in Mission and the Rio Grande Valley comes with many perks, but our warm, humid climate has a downside: it is the perfect breeding ground for termites. Often called “silent destroyers,” these pests can chew through the wooden structure of your home for years before you even notice them.

For homeowners in Mission, TX, waiting until you see a termite walking across the floor is often too late. By then, significant damage might already be done. The key to protecting your investment is catching them early.

Here are the 5 most common warning signs that termites might be hiding in your walls.

1. Mud Tubes on Exterior Walls

Subterranean termites, the most common type in Texas, need moisture to survive. They build pencil-sized tunnels made of mud, saliva, and dirt to travel safely from the soil to your house foundation.

Take a walk around the perimeter of your home. Check the foundation where it meets the ground. If you see brown, vein-like lines running up the concrete, do not scrape them away and ignore them. This is a clear highway for termites entering your home.

2. Discarded Wings on Windowsills

Have you noticed a pile of transparent, papery wings on your windowsill or near the door after a rainstorm? These didn’t just blow in.

These wings belong to “swarmers,” reproductive termites that leave the colony to start new ones. Once they find a mate and a place to nest (potentially your attic or walls), they shed their wings. Seeing wings is a major red flag that an active colony is nearby or already inside.

3. Hollow-Sounding Wood

Termites consume wood from the inside out, leaving a thin veneer of timber or paint on the surface. To the naked eye, the wood might look perfectly fine.

To check for this, go around your house and tap on wooden baseboards, door frames, or support beams with the handle of a screwdriver. If it sounds hollow or papery instead of creating a solid thud, or if the wood easily breaks away, you likely have a serious infestation eating away at the structure.

4. Frass (Termite Droppings)

While subterranean termites use their droppings to build tunnels, Drywood termites (another common pest in the RGV) push their droppings out of small holes in the wood.

This waste is called “frass.” To the untrained eye, it looks like a small pile of sawdust, coffee grounds, or sand. If you keep sweeping up mysterious piles of grit near your baseboards only for them to reappear a few days later, look up. You might have termites in the wood directly above that spot.

5. Stuck Windows or Hard-to-Close Doors

We often blame sticky doors on the Texas humidity, causing wood to expand. While that can be true, it is also a classic sign of termites.

As termites eat through wood, they produce moisture, which causes door and window frames to warp and become difficult to open or shut. If you have a window that suddenly feels jammed or a door that won’t latch properly, it’s worth getting a professional inspection to rule out pest damage.

Don’t Wait Until It’s Too Late

If you have noticed any of these signs, DIY sprays are rarely enough to stop an entire colony. Termites are relentless, and saving your home requires a professional strategy.
