5 Signs of a Termite Infestation in the DC Metro Area

Termites are one of the most destructive pests a homeowner can face—especially in a city like Washington, D.C., where older homes and humid conditions create the perfect environment for infestations. The biggest problem? Termites often go undetected until the damage is extensive and costly.

Knowing the early signs of termite activity can help you catch a problem before it spreads. In this guide, we'll cover the most common signs of a termite infestation in D.C., what to look for around your home, and when it's time to call in the professionals.

Sign #1. Mud Tubes Along Your Foundation or Walls

Mud tubes are one of the most telltale signs of a termite infestation. These pencil-sized tunnels are made of soil, saliva, and wood particles, and are usually found along concrete walls, crawl spaces, and foundation lines. Termites use them to travel safely between their underground colony and your home.

If you spot mud tubes, it's a strong indicator that active termites are present.

Sign #2. Discarded Wings Near Doors or Windows

Swarming termites (also called "alates") emerge to reproduce and start new colonies. After swarming, they shed their wings—and often leave piles behind near window sills, door frames, or light fixtures.

If you find discarded wings indoors, especially in the spring, it could mean a termite colony is nesting nearby.

Sign #3. Hollow or Damaged Wood

Termites consume wood from the inside out, so affected structures often sound hollow when tapped. Over time, this can lead to sagging floors, crumbling baseboards, or weakened walls.

Check wood around your home's foundation, crawl spaces, and basement for:

• A dull, papery sound when tapped
• Cracks or splintering wood
• Wood that gives way easily when pressed

Sign #4. Bubbling Paint or Stained Drywall

Termites produce moisture as they tunnel through walls, which can cause bubbling, peeling, or blistering paint that resembles water damage. You may also notice dark stains or spots on drywall or ceilings.

These subtle signs are easy to miss but can point to termite activity beneath the surface.

Sign #5. Tight-Fitting Doors or Windows

Termite damage can cause wood to warp, which may lead to windows or doors that suddenly become hard to open or close. If you've noticed unexpected sticking or swelling in doorframes or window sashes—especially in humid weather—it might be time to inspect for termites.

What to Do If You Suspect Termites

Termites cause billions of dollars in damage each year and are notoriously difficult to treat without professional help. If you notice any of these warning signs in your D.C. home, the safest next step is to schedule an expert termite inspection.
