- Insurance usually doesn’t cover termite damage.
Homeowners, landlords and anyone buying or selling a house in Roanoke, 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. Average winter lows near 29°F slow termites near the surface around Roanoke, 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.
- 1Screwdriver sinks easily into sills or trim.
- 2Piles of identical shed wings on windowsills.
- 3Mud in cracks of subfloor or joists.
- 4Live pale insects inside a broken mud tube.
- 5Discarded wings caught in spider webs.
- 6Sagging or spongy floors near exterior walls.
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.

Liquid Soil Termiticide Barrier
$1,200–$3,500 (often $3–$16 per linear foot)

- Best for
- Active subterranean termites; fast knockdown around the foundation
Fumigation for Drywood Termites

Prices are typical published ranges. Ask what’s included before you compare quotes.
Drywood termites can fly straight into attic framing through vents, so attics belong on the inspection list in warm climates.Which termites live around Roanoke.
It nests in soil and builds mud tubes to reach wood. It needs steady moisture. The termite you're most likely to meet in Roanoke is the eastern subterranean termite.
Local termites conditions in Roanoke.
An inspection in Roanoke usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Roanoke'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 Roanoke and Virginia 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. Roanoke 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 Roanoke homes, 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.
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.
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 Roanoke 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 Roanoke out to Blacksburg. A lot of houses around Roanoke are built over crawl spaces, and that's usually where termites start. Take a flashlight underneath.
A year of termites in Roanoke.
- Summer: with highs around 87°F in Roanoke, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 42 inches of rain a year in Roanoke, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Roanoke, before swarm season starts. - Spring: swarm season. For Roanoke homes, 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?
- 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. 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. Clear a path along the outside walls. Move stored boxes away from garage walls.
Mulch and termites.
A dry strip along the house lets you spot mud tubes. Wood chips right against siding hold moisture termites like. Keep mulch thin and pull it back from the foundation.
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
- Extent of existing damage needing repair.
- Warranty type: retreatment only or damage repair.
- Annual renewal and monitoring fees.
- Access to crawl spaces and attics.
- Whole-house fumigation versus spot treatment.
- Time of year and how booked up local companies are.

What's your biggest concern about termites?
When to call for help
Lenders often ask for one. It's also the cheapest termite service. Carpenter ants leave clean tunnels and sawdust. Termites leave mud. 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.
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
- Address wood-to-soil contact at steps, fences, and trellises.
- Store firewood well away from the house, off the ground.
- Check the foundation for mud tubes every spring.
- Set deck and porch posts on concrete, not soil.
- Install a vapor barrier over crawl space soil.
A liquid soil treatment goes into a trench along the foundation so termites cross it on their way to the house.Did you know?
Some African termite mounds stand more than 25 feet tall.
For Roanoke homes, soldier termites can't feed themselves, so the workers feed them mouth to mouth.
Questions people ask
Does fumigation kill subterranean termites too?
Not reliably. Tenting clears termites inside the house. It doesn't reach a colony living in the soil.
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.
What does a WDI report include?
It lists any termites or damage found. It also notes conditions that invite them, like wood touching soil. It only covers areas the inspector could reach.
What is the difference between subterranean and drywood termites?
Subterranean termites live in soil and build mud tubes. Drywood termites live inside the wood and leave tiny pellets. Around Roanoke, the subterranean kind causes most problems.
How do I choose a termite company?
Make sure they're licensed in Virginia. Ask which termites they found and what product they'll use. Ask what the warranty covers. Compare the proposals, not just the totals.
When is termite swarming season?
For Roanoke homes, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. For Roanoke homes, 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 Virginia?
Around Roanoke, the usual culprit is the eastern subterranean termite.
