Signs of Termites in McAllen Homes
Subterranean termites are the dominant termite threat in the Rio Grande Valley. McAllen's subtropical climate and mature tree canopy in older neighborhoods make certain homes especially vulnerable. Here's how to tell whether termites are active on your property.
Mud tubes along the foundation
Subterranean termites build pencil-width mud tubes along foundation walls, slab edges, and exterior walls to travel between their underground colony and their food source above ground. If you find these tubes, don't break them off and assume the problem is solved — the colony is still active underneath. A licensed technician will inspect active vs. abandoned tubes before recommending treatment.
Hollow-sounding wood
Tap baseboards, window frames, and exposed wood in older Central McAllen homes. Termite-damaged wood often sounds hollow or papery when tapped, because the insects eat the cellulose from the inside out. Surface paint may look intact even when the wood behind it is compromised.
Discarded wings in spring
In McAllen, termite swarmers typically emerge in spring. After mating, they drop their wings near windowsills and light sources. Small piles of translucent wings inside the home are a strong indicator that a colony is nearby — even if you don't see the insects themselves.
Why McAllen homes are vulnerable
Older McAllen neighborhoods like Bentsen Heights and the Central McAllen corridor have mature pecan and citrus trees shading older bungalow homes. Subterranean termites thrive in the moist soil beneath those trees. Newer construction in Sharyland and Bentsen Palm has a different risk profile — the risk is highest in the first few years after landscaping installs disturb the soil.
What to do if you suspect termites
Don't spray store-bought insecticide on the area — it can scatter the colony and make professional treatment harder. A licensed termite inspection typically costs $75–$150 in the Rio Grande Valley market, and full subterranean treatment ranges from $1,200 to $3,500 depending on the linear feet of foundation and the method used. See our cost guide for full ranges.
