Anyone in Asheville who owns, rents out, or is buying a home and wants to know whether termites are a real concern.
What to look for
Termites work quietly. A colony can feed inside a wall for years. Average winter lows near 28°F slow termites near the surface around Asheville, but they move deeper and keep feeding under heated homes. Spongy floors or bubbling paint usually mean long-running damage. So it's worth an inspection, even for one or two signs.
- 1Buckling laminate or warped hardwood flooring.
- 2Discarded wings caught in spider webs.
- 3Termite activity reported at a neighbor's home.
- 4Termite tubes hanging down from ceilings or joists.
- 5Blistered or bubbling paint on wood surfaces.
- 6Winged swarmers indoors, especially in spring.
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.
- Formosan colonies are large and can do serious damage quickly.

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. With a crawl space, the crew treats soil outside and underneath.
Which termites live around Asheville.
Their colonies are much bigger, though. They're less common. Formosan termites have turned up in parts of North Carolina. It needs steady moisture. It nests in soil and builds mud tubes to reach wood. The termite you're most likely to meet in Asheville is the eastern subterranean termite.
A downspout that dumps water at the foundation keeps the soil wet year-round. Extend it well away from the house.When termites swarm here.
Save a few in a bag, or snap a clear photo. A swarm inside usually means it's in the house. A swarm outside means a colony is nearby. Look for them on warm, humid evenings around porch lights. Around Asheville, formosan termites in North Carolina swarm later, from late April into June. Around Asheville, eastern subterranean termites usually swarm from April through May, typically on a warm, sunny day after rain. Swarm season is when termites show themselves.
Where to look around your house.
Standing water or a musty smell needs fixing either way. Check the piers, the sill plate and the floor joists. Take a flashlight underneath. A lot of houses around Asheville are built over crawl spaces, and that's usually where termites start.
A year of termites in Asheville.
- Winter: a good time to book an inspection in Asheville, before swarm season starts. - Fall: with about 45 inches of rain a year in Asheville, make sure gutters and downspouts carry water well away from the foundation. - Summer: with highs around 84°F in Asheville, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Spring: swarm season. Around Asheville, expect it from April through May. Check windowsills and light fixtures for wings.
What happens at an inspection.
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. 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.
Termites or ants?
- 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. - Waist: termites are thick through the middle. Ants are pinched. - Wings: termite wings are all the same length. Ant wings aren’t.
Getting ready for treatment day.
Drill holes in slabs or patios get patched afterward. Keep kids and pets inside while the Asheville crew applies the product, and ask how long to stay off treated soil. In North Carolina, native species begin swarming in late winter and continue into September or October, usually during the day on warm days following rain (NC State). Flag sprinkler heads and buried lines. Move boxes away from garage walls. Clear a walking path along the exterior walls. Prep is light for liquid treatments and bait stations.
Mulch and termites.
Wood chips touching the siding trap the moisture termites are after. A dry gap along the house makes mud tubes easier to spot; in Asheville that means extending downspouts and pulling mulch back from the slab. Pull mulch back from the foundation and keep the layer thin.
Questions to ask before you sign.
- 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 product or system will you use? - Which termites did you find, and where?
What affects the price
- Species: subterranean, drywood, or Formosan.
- Cubic footage under the tent for fumigation.
- Liquid barrier versus bait station system.
- Whole-house fumigation versus spot treatment.
- Number of bait stations required.
- Attached garages, decks, and additions.

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.

Simple ways to keep termites away
- Set deck and porch posts on concrete, not soil.
- Ventilate crawl spaces and control humidity.
- Fix leaking hose bibs, faucets, and pipes promptly.
- Caulk gaps around plumbing and utility penetrations.
- Seal cracks in the foundation and slab.
- Repair rotting trim, fascia, and window frames.
A liquid soil treatment goes into a trench along the foundation so termites cross it on their way to the house.Did you know?
Around Asheville, termites are closer cousins to cockroaches than to ants, despite the old nickname white ants.
Questions people ask
Are mud tubes always a sign of active termites?
Not always. Old tubes can stay on a wall for years. Break off a piece and check back in a week. If it's rebuilt, they're active.
Can termites damage a house on a concrete slab?
Yes. They come up through expansion joints, plumbing gaps and small cracks. Inspectors check those spots first.
Can I treat termites myself?
Prevention, yes. An active colony is harder. The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see.
Is termite treatment safe for kids and pets?
Used according to the label, yes. Soil treatments stay in the ground. Bait stations are locked and buried. Ask for the label and follow any re-entry times.
Do I have to leave my house during termite treatment?
Not for a soil treatment or bait stations. Fumigation is different. Everyone leaves for two to three days, pets and houseplants included.
What are the signs of termites that homeowners miss?
Around Asheville, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Around Asheville, 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 North Carolina?
Around Asheville, the usual culprit is the eastern subterranean termite.
