- Insurance usually doesn’t cover termite damage.
Anyone in Roanoke 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 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.
- 1Blistered or bubbling paint on wood surfaces.
- 2Sagging or spongy floors near exterior walls.
- 3Piles of identical shed wings on windowsills.
- 4Small kick-out holes in exposed wood.
- 5Live pale insects inside a broken mud tube.
- 6Layered, honeycombed wood packed with soil.
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.
📅
Termite activity through the year in Roanoke
Spring
swarm season. Across Roanoke, expect it from April through May. Check windowsills and light fixtures for wings.
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.

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 Roanoke home.
They also treat around piers and plumbing. Fix any moisture under the house too. Bait stations are the other main option. They're spaced every 10 to 20 feet. Termites carry the bait back to the colony. The stations are checked on a schedule, often every few months. With a crawl space, the crew treats soil outside and underneath.
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.
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.
Across Roanoke, 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. 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.
Where to look around your house.
Take a flashlight underneath. 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.
A year of termites in Roanoke.
- Winter: a good time to book an inspection in Roanoke, before swarm season starts. - Spring: swarm season. Across Roanoke, expect it from April through May. Check windowsills and light fixtures for wings. - 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.
What happens at an inspection.
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. 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.
Termites or ants?
- 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. - Antennae: termite antennae are straight. Ant antennae bend like an elbow. - Debris: termites leave mud. Carpenter ants leave sawdust.
Getting ready for treatment day.
Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines. Keep kids and pets inside while the Roanoke crew applies the product, and ask how long to stay off treated soil. In Virginia, eastern subterranean swarms February–June in the mid-Atlantic (Penn State/UGA). Drill holes in slabs or patios get patched afterward. Prep is light for liquid treatments and bait stations.
Mulch and termites.
A dry gap along the house makes mud tubes easier to spot; in Roanoke that means extending downspouts and pulling mulch back from the slab. Wood chips touching the siding trap the moisture termites are after. 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? - Which termites did you find, and where? - 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 affects the price
- Warranty type: retreatment only or damage repair.
- Species: subterranean, drywood, or Formosan.
- Attached garages, decks, and additions.
- Number of bait stations required.
- Extent of existing damage needing repair.
- Annual renewal and monitoring fees.

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.
Termites in Roanoke
About 42 inches of rain a year in Roanoke is plenty for subterranean termites, especially on any side of the house kept damp by gutters or sprinklers. Termite activity in Virginia is above average. Most houses will see termites at some point. With summer highs around 87°F, Roanoke's humid subtropical climate decides when local termites are busiest. A typical home in Roanoke is worth around $225k, which puts a few hundred dollars for an inspection and prevention in perspective. Roanoke has a humid subtropical climate, and termites activity here tends to pick up spring swarm season (March-May), warmer earlier in the south. Across Roanoke, most of the housing is urban, so the usual entry points, moisture spots, and sheltered areas near the structure are what an inspection checks first. Across Roanoke, take a minute to note where you have seen activity and when it appears, so the inspection is faster and the quote more accurate. A local provider who knows Roanoke and Virginia can point out the specific conditions that matter most here before you commit to a plan.

Simple ways to keep termites away
- Keep mulch at least a foot from the foundation.
- Never leave form boards or scrap lumber in the soil.
- Caulk gaps around plumbing and utility penetrations.
- Keep gutters clean so water does not pool.
- Install a vapor barrier over crawl space soil.
- Grade soil to slope away from the foundation.
An inspection starts outside, with a flashlight along the foundation line where mud tubes show up first.Did you know?
Across Roanoke, termites are closer cousins to cockroaches than to ants, despite the old nickname white ants.
Across Roanoke, some tropical termites grow fungus gardens inside the nest and eat the harvest.
Questions people ask
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.
How long do termite bait stations take to work?
Usually several weeks to a few months. Termites have to find the stations first. Then the bait spreads through the colony.
Do I need a termite inspection when buying a house?
Usually, yes. Many lenders ask for a wood-destroying insect (WDI) report. Either way, it's cheap peace of mind. Ask your agent when it's due.
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.
Will termites come back after treatment?
They can. Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for.
Can I pay for termite monitoring without a full treatment?
Across Roanoke, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Roanoke, 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.
