Homeowners, landlords and anyone buying or selling a house in Lexington, whether you've spotted something or just want to know what to watch for.
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. Winter lows around Lexington average near 25°F, so termites retreat deeper into the soil, though colonies under heated basements can stay active all winter.

- 2Mud in cracks of subfloor or joists.
- 3Tiny pinholes in drywall rimmed with mud.
- 4Mud tubes running up foundation walls or piers.
- 5Blistered or bubbling paint on wood surfaces.
- 6Buckling laminate or warped hardwood flooring.
Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.
- Damage hides behind drywall, flooring and trim.
- Homeowners insurance usually doesn’t cover termite damage.
- An active infestation can complicate a home sale.

Local termites conditions in Lexington.
Knowing Lexington's seasonal timing lets you schedule treatment before the busy stretch rather than after it, which usually means faster service and a more accurate quote. A provider who works Lexington and Kentucky every day can point out the specific conditions that matter most here, and getting the scope, price, and follow-up terms in writing makes it easier to compare options. Lexington sits in a humid subtropical climate, and that sets the pace for termite activity here: spring swarm season (March-May), warmer earlier in the south. In Lexington, the area is mostly urban, so termites pressure can differ from one block to the next depending on how tight the entry points are and how much food, water, or shelter is close by. An inspection in Lexington usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first.
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 inside usually means it's in the house. Save a few in a bag, or snap a clear photo. Swarm season is when termites show themselves. In Lexington, eastern subterranean termites usually swarm from April through May, typically on a warm, sunny day after rain. A swarm outside means a colony is nearby.
Where to look around your house.
Standing water or a musty smell needs fixing either way. The same advice applies across the area, from Lexington out to Nicholasville and Georgetown. A lot of houses around Lexington are built over crawl spaces, and that's usually where termites start. Take a flashlight underneath. Check the piers, the sill plate and the floor joists.
A year of termites in Lexington.
- Summer: with highs around 87°F in Lexington, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 45 inches of rain a year in Lexington, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Lexington, before swarm season starts. - Spring: swarm season. In Lexington, expect it from April through May. Check windowsills and light fixtures for wings.
What happens at an inspection.
They'll also go into the crawl space. A moisture meter and a probe help them find hidden activity. Afterward, ask them to show you what they found. Photos help. Most inspections take an hour or two. The inspector walks the outside of the house first. They check the foundation, the soil line and nearby wood. Inside, they check the garage, baseboards, plumbing gaps and the attic.
Termites or ants?
- Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Debris: termites leave mud. Carpenter ants leave sawdust. - Tunnels: termite galleries are packed with mud. Ant tunnels are clean and smooth. - Wings: termite wings are all the same length. Ant wings aren’t. - Waist: termites are thick through the middle. Ants are pinched.
Getting ready for treatment day.
Clear a path along the outside walls. Move stored boxes away from garage walls. Mark sprinkler heads and any buried lines. Keep pets and kids inside while the crew works outside. Ask how long to stay off treated soil. Any drill holes in a slab or patio get patched. Soil treatments and bait stations need little prep.
Mulch and termites.
Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation. A dry strip along the house lets you spot mud tubes.
Questions to ask before you sign.
- Is the whole foundation treated, or just one spot? - What does the warranty cover, and for how long? - What does the yearly renewal cost? - What do I need to do before and after treatment? - Which termites did you find, and where? - What product or system will you use?
What affects the price
- Amount of drilling through concrete and patios.
- Attached garages, decks, and additions.
- Wells, drains, or water features limiting chemical use.
- Warranty type: retreatment only or damage repair.
- Cubic footage under the tent for fumigation.
- 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
How long do termite bait stations take to work?
Termites have to find the stations first. Then the bait spreads through the colony. Usually several weeks to a few months.
Do I have to leave my house during termite treatment?
Fumigation is different. Everyone leaves for two to three days, pets and houseplants included. Not for a soil treatment or bait stations.
Does fumigation kill subterranean termites too?
Tenting clears termites inside the house. It doesn't reach a colony living in the soil. Not reliably.
What is the difference between subterranean and drywood termites?
Drywood termites live inside the wood and leave tiny pellets. Around Lexington, the subterranean kind causes most problems. Subterranean termites live in soil and build mud tubes.
How long does termite treatment take?
Bait stations take a few hours to install. Fumigation takes two to three days. A liquid barrier takes half a day to a day.
Are termite baits or liquid treatments more common?
In Lexington, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. In Lexington, 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 Kentucky?
Around Lexington, the usual culprit is the eastern subterranean termite.
