Homeowners, landlords and anyone buying or selling a house in Blacksburg, 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 Blacksburg average near 24°F, so termites retreat deeper into the soil, though colonies under heated basements can stay active all winter.

- 2Layered, honeycombed wood packed with soil.
- 3Tiny pinholes in drywall rimmed with mud.
- 4Dry hexagonal pellets under window frames or eaves.
- 5Winged swarmers indoors, especially in spring.

Why it’s worth acting soon
- Colonies grow and spread every year they go untreated.

- Homeowners insurance usually doesn’t cover termite damage.
- An active infestation can complicate a home sale.

Local termites conditions in Blacksburg.
A provider who works Blacksburg 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. Blacksburg 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. Across Blacksburg, the area is mostly suburban, 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 Blacksburg usually starts outside and works inward, checking the foundation, gaps around doors and windows, and any moisture or clutter near the structure first. Knowing Blacksburg'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 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. Swarm season is when termites show themselves. Across Blacksburg, 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.
Where to look around your house.
The same advice applies across the area, from Blacksburg out to Roanoke. A lot of houses around Blacksburg 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. Standing water or a musty smell needs fixing either way.
A year of termites in Blacksburg.
- Spring: swarm season. Across Blacksburg, expect it from April through May. Check windowsills and light fixtures for wings. - Summer: with highs around 83°F in Blacksburg, termites follow moisture, so watch AC drain lines, sprinkler zones and hose bibs. - Fall: with about 41 inches of rain a year in Blacksburg, make sure gutters and downspouts carry water well away from the foundation. - Winter: a good time to book an inspection in Blacksburg, before swarm season starts.
What happens at an inspection.
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. 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.
Keep kids and pets inside while the Blacksburg 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. Clear a walking path along the exterior walls. Move boxes away from garage walls. Flag sprinkler heads and buried lines.
Mulch and termites.
Pull mulch back from the foundation and keep the layer thin. A dry gap along the house makes mud tubes easier to spot; in Blacksburg that means extending downspouts and pulling mulch back from the slab. Wood chips touching the siding trap the moisture termites are after.
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
- Linear feet of foundation to be treated.
- Slab, crawl space, or basement construction.
- Attached garages, decks, and additions.
- Access to crawl spaces and attics.
- Whole-house fumigation versus spot treatment.
- Extent of existing damage needing repair.

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
Some of the work is yours. Pull mulch back from the foundation. Fix leaks and clear gutters. Keep firewood away from the house. 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.

Simple ways to keep termites away
- Keep six inches between soil and siding or wood.
- Install a vapor barrier over crawl space soil.
- Address wood-to-soil contact at steps, fences, and trellises.
- Remove tree stumps and buried wood near the house.
- Check the foundation for mud tubes every spring.
- Extend downspouts so water drains away from walls.

Questions people ask
Can I treat termites myself?
The product must reach the whole colony. It also needs even coverage around the foundation. Store-bought sprays usually kill only what you see. Prevention, yes. An active colony is harder.
Do I need a termite inspection when buying a house?
Either way, it's cheap peace of mind. Ask your agent when it's due. Usually, yes. Many lenders ask for a wood-destroying insect (WDI) report.
Are mud tubes always a sign of active termites?
Break off a piece and check back in a week. If it's rebuilt, they're active. Not always. Old tubes can stay on a wall for years.
Will termites come back after treatment?
Treatments wear down and new colonies move in. That's what yearly inspections and renewal plans are for. They can.
Does fumigation kill subterranean termites too?
Tenting clears termites inside the house. It doesn't reach a colony living in the soil. Not reliably.
How do I know if I have termites or ants?
Across Blacksburg, termites are best caught early through inspection, because the damage is hidden inside wood until it is far along. Across Blacksburg, 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.
What is a termite renewal contract?
83% of locations in PCT magazine's 2025 termite market report (about 145 pest-control professionals, 2024 operations) offered annual renewals.
Are termites common in Virginia?
