5 Signs You Have a Termite Problem Before It's Too Late

Termites are one of the most destructive pests a homeowner can face — and one of the sneakiest. Unlike ants marching across your kitchen counter or a mouse scratching in the walls, termites can eat through your home's structure for months or even years before you notice anything is wrong.

Here in Northern California, termite activity spikes every spring and summer. The warm, dry climate across the Sacramento Valley and into the Oroville, Chico, and Paradise foothills creates ideal conditions for both subterranean and drywood termites. And if your home was built or rebuilt with fresh lumber — especially in wildfire recovery zones — you may be at even greater risk.

The good news? If you know what to look for, you can catch a termite problem early and save yourself thousands of dollars in structural damage.

Here are five warning signs every Northern California homeowner should know.

1. Mud Tubes Along Your Foundation

Subterranean termites build pencil-thin mud tubes to travel between the soil and the wood they're feeding on. These tubes protect them from exposure and keep moisture in as they move.

Check along the exterior foundation of your home, inside your garage, and around any concrete or masonry that contacts the ground. If you see thin, dried-mud lines running vertically along these surfaces, you're likely looking at an active or recent termite highway.

Even if the tubes appear dry or abandoned, it's worth having a professional inspection done. Termites often build new routes nearby.

2. Swarmers or Discarded Wings Near Windows and Doors

Every spring and early summer, mature termite colonies send out winged reproductives — called swarmers — to start new colonies. In Northern California, this usually happens during warm evenings after rain or irrigation.

You might notice a sudden cloud of small, winged insects near outdoor lights, or find dozens of tiny translucent wings scattered on windowsills, near sliding doors, or along the foundation. The swarmers themselves look similar to flying ants, but there's a key difference: termite swarmers have straight antennae, a thick waist, and wings that are equal in length. Flying ants have elbowed antennae, a pinched waist, and uneven wings.

If you're finding discarded wings inside your home, that's an even stronger indicator. It means swarmers emerged from within or very near your structure.

3. Hollow-Sounding or Soft Wood

Termites eat wood from the inside out. That means a beam, baseboard, or door frame can look perfectly fine on the surface while being nearly hollow inside.

Tap suspect areas with a screwdriver handle or your knuckle. Solid wood produces a firm, dense sound. Wood that's been compromised by termites will sound noticeably hollow or papery. In some cases, a screwdriver will push right through the surface with minimal pressure — revealing a honeycomb of damage underneath.

Pay special attention to wood that contacts or is near the ground: deck posts, porch supports, garage door frames, and subfloor joists in crawl spaces.

4. Frass — Tiny Pellets That Look Like Sawdust

Drywood termites — common in Northern California — don't build mud tubes. Instead, they live entirely inside the wood they're consuming. As they eat, they push their waste out through small "kick holes" in the surface.

This waste, called frass, looks like fine, six-sided pellets — almost like coarse sand or sawdust with a slightly granular texture. You'll usually find small piles of frass on windowsills, along baseboards, or beneath wooden furniture.

If you're sweeping up what looks like sawdust in the same spot repeatedly and there's no obvious source, drywood termites are a strong possibility.

5. Doors and Windows That Suddenly Stick

If your doors or windows start jamming, sticking, or becoming difficult to open and close — and it's not due to seasonal humidity — termites could be the cause.

As termites consume the wood in and around frames, they create moisture and structural warping. This subtle shift can throw door and window frames out of square, making them bind in ways they didn't before.

This is one of the most commonly overlooked signs because homeowners tend to chalk it up to the house "settling." If the sticking is sudden or isolated to one area, it's worth investigating further.

What to Do If You Spot Any of These Signs

If even one of these signs looks familiar, don't wait. Termite damage compounds over time, and what starts as a minor colony can turn into a serious structural issue within a year.
