5 Warning Signs You May Have Termites in Your California Home

Termites are one of the most destructive pests in California, causing billions of dollars in structural damage each year. Because they often remain hidden, many homeowners don’t realize there’s a problem until significant damage has already occurred. Knowing the early warning signs can protect your home — and your wallet.

1. Mud Tubes Along the Foundation

Subterranean termites build pencil-sized mud tubes along foundations, walls, or crawl spaces to travel safely between their nest and food source.

2. Hollow-Sounding Wood

If you tap on wood beams, baseboards, or walls and they sound hollow, termites may be feeding inside.

3. Discarded Wings

During swarming season (often spring in California), termites shed their wings near windows, doors, or light sources.

4. Bubbling or Blistering Paint

Damaged wood beneath the surface can make paint appear bubbled or water-damaged.

5. Tight Doors and Windows

Termite-damaged wood can warp, causing doors and windows to stick.
