Signs of Termites Every Homeowner Should Watch For

Termites are sneaky: they quietly chew wood from the inside out, and by the time you notice visible damage it can be expensive to fix. That’s why early detection matters. In the U.S. termites cause billions in structural damage each year, and homeowners who catch an infestation early dramatically reduce repair costs and stress. 

Below is a clear, homeowner-friendly checklist of the most common signs of termites—what to look for, how to check safely, and when to call a licensed professional like Specter Pest Control.

1. Mud tubes (a classic sign of subterranean termites)

If you find narrow, pencil-wide tunnels made from soil and saliva running up foundation walls, piers, or floor joists, that’s a strong indicator of subterranean termites. These “mud tubes” let termites travel from the ground to above-ground food sources while staying protected from dry air. If you see them, don’t break them open repeatedly—take photos and call a pro. 

What to do: Photograph the tubes, leave them intact for inspection, and contact a licensed inspector.

2. Swarmers and discarded wings

Winged termites (swarmers) are reproductive adults that leave a colony to start new ones. Finding piles of tiny, translucent wings near windowsills, doors, light fixtures, or baseboards—especially in spring—often means termite swarmers emerged inside your home or from nearby wood. Don’t confuse them with flying ants; termite wings are equal in size and often found in concentrated piles. 

What to do: Save a sample (or take a photo) and call for an inspection—swarmers are a strong reason to act quickly.

3. Frass (drywood termite droppings)

Drywood termites push tiny, wood-colored pellets called frass out of their galleries. These pellets look like coarse sawdust or coffee grounds and often accumulate in small piles near the infestation site (windowsills, furniture, or trim). If you spot frass, the colony is likely inside the wood itself rather than in the soil.

What to do: Don’t simply sweep it away—frass indicates active feeding. Call a technician to identify the species and recommend treatment options.

4. Hollow-sounding or damaged wood, and structural signs

Termites eat wood from the inside out. When you tap suspect areas (sill plates, studs, floor joists) they may sound hollow, or wood may crumble under a screwdriver. Other clues include buckling or blistering paint, sagging floors, or doors and windows that suddenly stick—these can all point to termite damage beneath the surface. 

What to do: Note where the changes occur and arrange a professional inspection—structural problems should be assessed sooner rather than later.

5. Tiny holes, soil pellets, or mud near wood

Look for small holes or minute soil pellicles on wooden surfaces and along foundations. Subterranean termites sometimes leave soil deposits where they enter wood, and drywood termites can leave tiny exit holes and pellets. These are subtle signs that often accompany more obvious indicators. 

What to do: Photograph and mark the area; a trained inspector can probe surrounding wood to determine the scope.

Why species identification matters

Different termites behave differently. Subterranean termites build mud tubes and live in the soil; drywood termites nest inside wood and produce frass. Treatment options and prevention strategies depend on which species you have, so an accurate identification by a licensed technician is essential. 

Quick homeowner prevention checklist

These actions reduce the chance of termite colonization and help make early signs easier to spot:

• Remove wood-to-soil contact. Keep lumber, mulch, and firewood at least a few feet from your foundation.

• Control moisture. Fix leaks, maintain proper grading and gutter drainage, and keep crawlspaces ventilated—termites need moisture.

• Seal entry points. Caulk cracks where utilities enter the house and repair damaged siding or screens.

• Inspect regularly. Add a termite check to your annual home maintenance routine—early detection is the most cost-effective defense.
