Signs of Termites: What to Look For
Updated August 6, 2026 · 6 min read
Termites can cause serious damage to your home without obvious signs at first. Early detection is key to preventing costly repairs. Look for mud tubes, hollow wood, or discarded wings to identify termite activity.
What Signs Show Termite Activity?
Termites often go unnoticed until damage is significant. The most common signs include mud tubes, swarmers, and hollow wood. These signs point to a colony inside your home.
Mud Tubes
Mud tubes are pencil-thin tunnels built by termites to travel between their colony and food sources. They are typically found on foundations, walls, or support beams.
Swarmers and Discarded Wings
Termite swarmers are winged adults that leave colonies to start new ones. After swarming, they shed their wings, which may be found near windowsills or doorways.
Hollow or Damaged Wood
Tapping on wood may reveal a hollow sound. Termites eat wood from the inside out, leaving only a thin shell or bubbling paint.

How to Identify Termite Damage
The most common causes of termite damage are wooden structures, foundations, and support beams. These areas are most vulnerable to hidden termite activity.
- Check under and around baseboards
- Look for frass (termite droppings) near wood
- Inspect attic and crawl spaces regularly
- Test wood with a knife or screwdriver
When to Call a Professional
If you notice multiple signs, or suspect a large colony, contact a licensed termite inspector immediately. Professional treatment is often needed to stop the infestation.
Danger signs include sagging floors, cracked paint, or structural movement. These indicate serious damage and require an expert.
