Signs of Termites in Your Home: What to Look For

Imagine this: It’s a beautiful spring day in Knoxville, and you’re enjoying your morning coffee on the deck. Everything seems fine—until you notice a few strange things around the house that just don’t add up. A pile of tiny wings by the window. A soft, hollow sound when you tap on the baseboard. Or those mysterious mud lines crawling up your foundation.

These could be early warning signs of termites, one of the most destructive pests in East Tennessee. Because of our humid climate and abundant wooded areas, termites thrive here. The good news? Catching them early can save you thousands in repairs.

At Southeast Termite & Pest Control, we’ve been helping Knoxville-area homeowners protect their properties since 1971. In this guide, we’ll walk you through the most common signs of termites, what they mean, and what you should do next.

Why Termites Love Homes in knoxville

East Tennessee’s warm, humid summers and mild winters create the perfect environment for subterranean termites—the most common type in our region. These pests live in the soil and constantly look for ways to invade homes through even the tiniest cracks.

According to industry reports, termites damage over 600,000 homes across the U.S. each year, costing homeowners billions in repairs. The average repair job often runs around $3,000, but severe cases can climb much higher.

Because termites work quietly from the inside out, many homeowners don’t realize there’s a problem until significant damage has already occurred.

Top Signs of Termites You Should Never Ignore

1. Discarded Wings and Swarmers

One of the most obvious signs is finding piles of translucent, beige or brown wings near windowsills, doors, or light fixtures. Termites (often called “swarmers”) shed their wings after mating flights. In Knoxville and surrounding areas like Maryville, Farragut, and Sevierville, swarm season typically peaks from March through May, especially after warm spring rains.

Important tip: Don’t confuse them with flying ants. Termite swarmers have straight antennae, a thick waist, and wings that are all the same size. Flying ants have elbowed antennae, a pinched waist, and front wings longer than the back ones.

If you see swarmers inside your home, it’s a strong indicator of an active colony nearby.

2. Mud Tubes

Look for pencil-thick, brown mud tubes running up your foundation walls, along crawl space piers, or even inside walls. Subterranean termites build these shelter tubes to travel from the soil to wooden structures while staying protected from drying out and predators.

These tubes are a major red flag in East Tennessee homes, especially those with crawl spaces. If you break a tube and see termites inside—or if the tubes reappear quickly—you likely have an active infestation.

3. Hollow-Sounding or Damaged Wood

Termites eat wood from the inside out, leaving a thin outer shell. Tap on baseboards, window frames, door trim, or flooring with a screwdriver. A dull, hollow, or papery sound often means termites have been at work.

Other wood damage signs include:

• Blistering or buckling floors
• Cracked or bubbling paint on walls or trim
• Wood that feels soft, spongy, or crumbles easily
• Sagging ceilings or floors in severe cases

4. Frass (Termite Droppings)

While less common with subterranean termites, drywood termites (occasionally found in our area) leave behind tiny pellet-like droppings called “frass.” These look like fine sawdust or coffee grounds and often pile up beneath infested wood or near kick-out holes.

5. Other Subtle Signs

• Stuck doors or windows: Warped frames from internal damage or moisture associated with termite activity.
• Musty odors: Sometimes a faint moldy smell comes from damaged wood in walls or crawl spaces.
• Clicking or rustling sounds: In advanced infestations, soldier termites may bang their heads to alert the colony.

Common Termite Hotspots in Knoxville Homes

Pay special attention to these areas during your inspection:

• Crawl spaces and basements (high moisture = high risk)
• Foundation walls and exterior siding
• Porches, decks, and wooden steps
• Attics and roof eaves
• Areas near plumbing or leaky gutters

Our humid East Tennessee climate makes crawl space issues especially common, which is why many local homeowners also consider crawl space encapsulation for long-term protection.

What to Do If You Suspect Termites

Don’t panic—but don’t wait either. Termites can cause extensive hidden damage in a relatively short time.

Here’s your action plan:

1. Document what you find (take clear photos)
2. Avoid disturbing mud tubes or damaged wood too much (this can make professional diagnosis harder)
3. Contact a local professional for a thorough inspection

DIY treatments are rarely effective against termites because colonies can extend deep underground and contain hundreds of thousands of insects.

Prevention Tips for Knoxville Homeowners

While professional treatment is the most reliable solution, you can reduce your risk by:

• Eliminating wood-to-soil contact around your foundation
• Fixing moisture issues (leaky gutters, poor drainage)
• Keeping mulch and landscaping a few inches away from your siding
• Scheduling annual termite inspections
• Considering preventive treatments or bait systems
