What to look for
Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs. Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 28°F slow termites near the surface around Clarksville, but they move deeper and keep feeding under heated homes.

Crawl spaces are where termites usually get in. Joists, piers and the sill plate should all get a close look.How treatment works on a typical Clarksville home.
With a crawl space, the crew treats soil outside and underneath. The stations are checked on a schedule, often every few months. Termites carry the bait back to the colony. They're spaced every 10 to 20 feet. Bait stations are the other main option. Fix any moisture under the house too. They also treat around piers and plumbing.
Which termites live around Clarksville.
The termite you're most likely to meet in Clarksville is the eastern subterranean termite. It needs steady moisture. It nests in soil and builds mud tubes to reach wood.
Subterranean termites don't stop in winter; they just go deeper. A quiet season is a good time for a non-urgent inspection.When termites swarm here.
A swarm outside means a colony is nearby. Around Clarksville, eastern subterranean termites usually swarm from April through May, typically on a warm, sunny day after rain. Swarm season is when termites show themselves. Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house.
Where to look around your house.
Check the piers, the sill plate and the floor joists. Take a flashlight underneath. A lot of houses around Clarksville are built over crawl spaces, and that's usually where termites start. The same advice applies across the area, from Clarksville out to Nashville. Standing water or a musty smell needs fixing either way.
A year of termites in Clarksville.
- Spring: swarm season. Around Clarksville, expect it from April through May. Check windowsills and light fixtures for wings. - Winter: a good time to book an inspection in Clarksville, before swarm season starts. - Fall: with about 50 inches of rain a year in Clarksville, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 90°F in Clarksville, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs.
What happens at an inspection.
Inside, they check the garage, baseboards, plumbing gaps and the attic. They check the foundation, the soil line and nearby wood. The inspector walks the outside of the house first. Most inspections take an hour or two. Photos help. Afterward, ask them to show you what they found. A moisture meter and a probe help them find hidden activity. They'll also go into the crawl space.
Termites or ants?
- Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Debris: termites leave mud. Carpenter ants leave sawdust. - Antennae: termite antennae are straight. Ant antennae bend like an elbow.
Getting ready for treatment day.
Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations. Drill holes in slabs or patios get patched afterward. Keep kids and pets inside while the Clarksville crew applies the product, and ask how long to stay off treated soil. In Tennessee, eastern subterranean swarms in late winter and spring (UGA); Formosan swarms evenings April–July (FDACS). Flag sprinkler heads and buried lines.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in Clarksville that means extending downspouts and pulling mulch back from the slab. Pull mulch back from the foundation and keep the layer thin. Wood chips touching the siding trap the moisture termites are after.
Questions to ask before you sign.
- What product or system will you use? - Which termites did you find, and where? - What do I need to do before and after treatment? - What does the yearly renewal cost? - What does the warranty cover, and for how long? - Is the whole foundation treated, or just one spot?
What affects the price
- Number of bait stations required.
- Warranty type: retreatment only or damage repair.
- Attached garages, decks, and additions.
- Annual renewal and monitoring fees.
- Whole-house fumigation versus spot treatment.
- Access to crawl spaces and attics.

What's your biggest concern about termites?
When to call for help
Termites leave mud. Carpenter ants leave clean tunnels and sawdust. It's also the cheapest termite service. Lenders often ask for one. Get a wood-destroying insect (WDI) report either way. Buying or selling? Hollow-sounding wood is another clue. Call if you see mud tubes, pellets or an indoor swarm.
What you can do yourself
Treating an active colony is harder. The product has to reach the whole colony. It also needs even coverage around the entire foundation. Store-bought sprays usually kill only the termites you see. Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house.

Questions people ask
Is termite treatment safe for kids and pets?
Bait stations are locked and buried. Ask for the label and follow any re-entry times. Used according to the label, yes. Soil treatments stay in the ground.
Does fumigation kill subterranean termites too?
Tenting clears termites inside the house. It doesn't reach a colony living in the soil. Not reliably.
Will termites come back after treatment?
Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for. They can.
What does a WDI report include?
It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach. It lists any termites or damage found.
What is the difference between subterranean and drywood termites?
Drywood termites live inside the wood and leave tiny pellets. Around Clarksville, the subterranean kind causes most problems. Subterranean termites live in soil and build mud tubes.
How do I know if I have termites or ants?
Around Clarksville, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Clarksville, a professional inspection looks for mud tubes, damaged wood, and swarming activity, and treatment targets the soil and the colony rather than just the visible wood.
Are termites common in Tennessee?
Around Clarksville, the usual culprit is the eastern subterranean termite.
