Termite Control in McAllen & the Upper Valley

The signs Valley homeowners actually see

• Mud tubes — pencil-width dirt tunnels climbing the slab edge, garage walls, or plumbing penetrations. The classic RGV find.
• Swarmers — winged termites indoors, usually after a warm rain, often near windows. Shed wings on the sill count too.
• Hollow or blistered wood — baseboards and door frames that sound papery, paint that bubbles over intact-looking wood.
• Nothing at all — the most common sign. Termites eat from the inside; that's why the free inspection exists.

How treatment works here

For the subterranean termites that dominate the Valley, the standard is a liquid soil treatment — a continuous treated zone around and under the foundation's entry points. Termites tunnel through it, carry it back, and the colony collapses; done right, one treatment protects for years. Pricing depends on the home's linear footage and slab layout, typically $800–$1,800 for an average Valley single-story — you'll get the exact number in writing after the inspection, plus what it covers and for how long. Drywood termites (less common inland, but they turn up) are a different treatment conversation entirely, which is one reason a real inspection beats a phone guess.

What makes the RGV a termite hotspot

No winter freeze means colonies forage year-round instead of pausing. Lawn irrigation keeps the soil moisture right where termites want it — up against the slab. And decades of citrus and farmland conversion mean many subdivisions in McAllen, Pharr, and Alamo sit on ground that fed termite colonies long before it held houses. Older neighborhoods with mature trees and original plumbing penetrations see the most activity, but new construction isn't exempt — builders' pre-treatments wear out, usually quietly, at year 5–10.

The honest version of "termite prevention"

Things that genuinely help and cost nothing: keep mulch and soil grade a few inches below slab level, fix hose bibs and AC condensate lines that keep one patch of soil permanently wet, don't stack firewood against the house, and glance at your slab edge for mud tubes once a season. Things that don't help: the hardware-store termite sprays — surface sprays kill the ones you see and leave the colony untouched. If you find a tube, don't knock it down before someone looks at it; an active tube tells an inspector far more than a cleaned wall.
