Homeowners, landlords and anyone buying or selling a house in Henderson, whether you've spotted something or just want to know what to watch for.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Winter lows around Henderson average near 26°F, so termites retreat deeper into the soil, though colonies under heated basements can stay active all winter. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.
- 1Mud in cracks of subfloor or joists.
- 2Small kick-out holes in exposed wood.
- 3Mud tubes running up foundation walls or piers.
- 4Tiny pinholes in drywall rimmed with mud.
- 5Layered, honeycombed wood packed with soil.
- 6Discarded wings caught in spider webs.
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 Henderson.
An inspection in Henderson usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Henderson'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 Henderson 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. Henderson 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. For Henderson homes, the area is mostly rural, 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.
Mulch piled against the house and a dripping hose bib give termites moisture and cover. Pull mulch back and fix the drip.When termites swarm here.
A swarm outside means a colony is nearby. 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. For Henderson homes, eastern subterranean termites usually swarm from April through May, typically on a warm, sunny day after rain.
Where to look around your house.
Check the piers, the sill plate and the floor joists. Standing water or a musty smell needs fixing either way. The same advice applies across the area, from Henderson out to Owensboro. A lot of houses around Henderson are built over crawl spaces, and that's usually where termites start. Take a flashlight underneath.
A year of termites in Henderson.
- Fall: with about 46 inches of rain a year in Henderson, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 89°F in Henderson, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Spring: swarm season. For Henderson homes, expect it from April through May. Check windowsills and light fixtures for wings. - Winter: a good time to book an inspection in Henderson, before swarm season starts.
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. - 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.
Getting ready for treatment day.
Mark sprinkler heads and any buried lines. Move stored boxes away from garage walls. Clear a path along the outside walls. Soil treatments and bait stations need little prep. Any drill holes in a slab or patio get patched. Ask how long to stay off treated soil. Keep pets and kids inside while the crew works outside.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Keep mulch thin and pull it back from the foundation. Wood chips right against siding hold moisture termites like.
Questions to ask before you sign.
- What product or system will you use? - 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 affects the price
- Whole-house fumigation versus spot treatment.
- Attached garages, decks, and additions.
- Liquid barrier versus bait station system.
- Access to crawl spaces and attics.
- Amount of drilling through concrete and patios.
- Species: subterranean, drywood, or Formosan.

What's your biggest concern about termites?
When to call for help
Call if you see mud tubes, pellets or an indoor swarm. Hollow-sounding wood is another clue. Buying or selling? Get a wood-destroying insect (WDI) report either way. Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud.
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.
