6 Termite Warning Signs Every Arizona Homeowner Should Know

Termites cause more property damage nationwide than fires and storms combined, and Arizona’s warm climate keeps subterranean termites active nearly year-round. Because they feed out of sight, inside walls, under slabs, behind baseboards, many homeowners don’t discover an infestation until repairs are already needed. Here’s what to watch for.

1. Mud Tubes Along the Foundation

Subterranean termites build pencil-width mud tubes to travel between their underground colony and their food source (your home’s wood framing) while staying protected from open air. Look for these tubes running up exterior foundation walls, especially in shaded or irrigated areas.

2. Hollow-Sounding or Damaged Wood

Tap on exposed wood trim, baseboards, or door frames. Wood that sounds hollow, feels soft, or crumbles easily has likely been hollowed out from the inside, a hallmark sign of termite feeding.

3. Discarded Wings Near Windows and Doors

Each spring, mature termite colonies send out “swarmers”, winged reproductive termites, to start new colonies. After swarming, they shed their wings. Finding small, uniform wings near windowsills or light fixtures is often the first visible sign of a nearby colony.

4. Sagging Doors, Windows, or Flooring

As termites hollow out structural wood, doors and windows can start to stick or sag, and flooring may feel uneven or spongy in spots. These symptoms are often mistaken for normal settling, which delays treatment.

5. Small Pinholes in Drywall

Termites sometimes create tiny holes in drywall as they tunnel, occasionally accompanied by a fine, sawdust-like material. This is easy to miss during a casual walkthrough.

6. Tightening or Buckling Paint

Excess moisture from termite activity behind painted wood or drywall can cause the paint to bubble, crack, or peel, similar to water damage, another sign that’s often misattributed to something else.

Why Termites Thrive in the East Valley

Subterranean termites need moisture to survive, and the irrigation systems, pools, and lush landscaping common in Gilbert, Chandler, and Queen Creek create exactly the conditions they’re looking for in an otherwise dry climate. Homes with wood-to-soil contact, over-irrigated planters, or leaking exterior spigots are at the highest risk.

What to Do If You Spot These Signs

Termite damage typically isn’t covered by homeowner’s insurance, which makes early detection the most cost-effective form of protection. If you notice any of the signs above:

1. Avoid disturbing mud tubes, professionals use them to assess colony activity.
2. Reduce moisture near the foundation where possible.
3. Schedule a professional termite inspection before making repairs.
