Signs of Termite Damage: How to Spot an Infestation

June 20, 2025

Termite damage often hides beneath the surface, silently eating away at your home’s structural integrity. Knowing the signs of termite damage early can save you thousands in repairs and help you act before the infestation spreads.

Why Termite Damage Should Never Be Ignored

Termites cause more than $5 billion in property damage annually in the U.S., and most insurance policies don’t cover it. Whether you’re a homeowner, real estate agent, or home inspector, identifying termite activity early is essential to avoid costly structural repairs and ensure a safe living environment.

🔍 Common Signs of Termite Damage

1. Hollow or Papery-Sounding Wood

Tap on wood around the house—such as baseboards, windowsills, or door frames. If it sounds hollow or unusually soft, termites may have eaten the inside.

🧠 How do you know if termites are in your walls?
Knock on walls to check for hollow spots. You may also hear faint clicking or chewing noises from within the wall.

2. Mud Tubes Along Walls or Foundation

Subterranean termites build mud tunnels to travel from the ground to their food source. These pencil-width tubes are commonly found on foundations, basement walls, or crawl spaces.

👉 A full termite inspection will identify active tubes and entry points.

3. Bubbling or Blistered Paint

Moisture caused by termites tunneling beneath the surface can cause paint to bubble or peel, often mistaken for water damage.

4. Frass (Termite Droppings)

Drywood termites leave behind tiny, oval-shaped droppings resembling sawdust or coffee grounds. These often collect beneath infested wood or along window sills.

5. Warped Doors and Windows

As termites chew through wood, they can cause it to swell, making doors or windows harder to open and close. This is often one of the first noticeable signs of termite infestation.

6. Discarded Wings

Termite swarmers shed their wings after mating. If you notice piles of tiny, clear wings near windowsills, light fixtures, or door frames, it’s a sign that a colony may be forming inside your home.

7. Tunnels in Exposed Wood

When wood is broken or damaged, you may see maze-like tunnels inside. This is often visible in attics, garages, or during remodeling.

What Does the Beginning of Termite Damage Look Like?

Early signs are subtle and easy to miss:

  • Small cracks or bubbling paint
  • Tiny pinholes in drywall
  • Slightly sagging floors or ceilings
  • A soft click or tapping sound inside walls

Homeowners often mistake these early clues for humidity or settling, which allows termites to continue destroying wood unnoticed for years.

🏚️ Can You Live in a House With Termite Damage?

Yes, but it depends on the extent of the damage. Minor infestations may not pose immediate risks, but long-term or advanced termite damage can threaten your home’s structural stability.

It’s important to:

  • Get a termite inspection immediately
  • Treat the infestation
  • Repair compromised structures through termite damage repair

Living in a termite-damaged home without remediation can be dangerous.
