Subterranean termites are common in Middle Tennessee. Signs include winged swarmers or shed wings indoors in spring, mud tubes on foundations or crawlspace piers, and hollow or damaged wood. A licensed pest control company can inspect the home and recommend liquid soil treatment, baiting systems, or a combination, usually with an annual renewal agreement.

Subterranean termites are common across Middle Tennessee. They live in colonies in the soil and travel into homes to feed on wood, often without being seen for a long time. Because damage can build slowly and out of sight, termites are one pest where a professional inspection really matters.
Signs of termites
- Swarmers. Winged termites emerging indoors or near the foundation, most often on warm days in spring. Piles of shed wings on windowsills are a strong clue.
- Mud tubes. Pencil-width tunnels of soil on foundation walls, piers, or in the crawlspace. Termites build them to stay protected while they travel.
- Damaged wood. Wood that sounds hollow, has soil packed into galleries, or crumbles easily, especially near moisture.
- Bubbling paint or sagging floors in some cases, though these can have other causes.
Flying ant or termite?
Swarming ants and swarming termites are easy to confuse. Termites have straight antennae, a thick waist, and two pairs of wings that are about equal in length. Ants have elbowed antennae, a pinched waist, and front wings that are longer than the back wings. If you're not sure, save a few in a sealed bag for the technician.
Common treatment approaches
- Liquid soil treatments. A termiticide is applied to the soil around and sometimes under the foundation to create a treated zone termites contact as they forage.
- Baiting systems. Bait stations are installed in the soil around the home and monitored. Termites carry the bait back to the colony.
- Wood treatments. Some products are applied directly to wood, often as part of a broader plan.
Which approach fits depends on the home's construction, the extent of activity, and access. Ask the company to explain why they recommend a particular method for your house.
Why crawlspaces matter
Crawlspaces that stay damp, have wood touching soil, or have debris left from construction are especially attractive to subterranean termites. A thorough inspection should include the crawlspace, and many technicians will point out moisture problems, such as missing vapor barriers or poor drainage, that make the home more vulnerable.
Warranties and renewals
Many termite treatments come with an annual renewal agreement. Read it carefully: some cover retreatment only, while others also cover repair of new damage under certain conditions. Ask what's covered, what the yearly inspection includes, and what happens if the home changes hands.
Buying or selling a home
In Tennessee real estate transactions, lenders often ask for a wood destroying insect inspection report. These are typically prepared by a licensed pest control company. If you're buying, read the report closely and ask about any previous treatment and active warranty.
What to do now
- Don't disturb mud tubes or spray swarmers. Leave evidence for the inspector.
- Take photos and note where you've seen activity.
- Move firewood and wood debris away from the foundation.

Frequently asked questions
When do termites swarm in Middle Tennessee?
Subterranean termite swarms are most common on warm days in spring, often after rain, though timing varies year to year. Swarmers inside the house are a strong sign of an active colony nearby.
How can I tell a flying ant from a termite?
Termites have straight antennae, a thick waist, and two pairs of wings about equal in length. Flying ants have elbowed antennae, a pinched waist, and front wings longer than their back wings. Save a few for the inspector if you're unsure.
What does a termite renewal or warranty cover?
It varies. Some agreements cover retreatment only, while others also cover repair of new damage under specific conditions. Read the agreement carefully and ask what the annual inspection includes.
