Virginia sits in termite country. The species you are almost certainly dealing with is the eastern subterranean termite — colonies underground, reaching wood above ground through mud tubes, swarming from March through June on warm days after rain. Drywood termites turn up occasionally in the southeastern coastal part of the state. Formosan termites, despite appearing on several Virginia pest company pages, are not established here.
The practical point is not that termites exist. It is that by the time you see anything, the colony has usually been there for years.
This is general information. Identification and extent can only be established by a licensed inspector examining the property.
The species question, settled
Eastern subterranean termite. The common one, and the one behind almost every Virginia treatment. Colonies live in soil and require the humidity it provides, which is why they build mud tubes to reach wood above ground. A mature colony can number in the millions and feeds continuously rather than seasonally.
Drywood termites. Occasionally present in southeastern coastal areas. They do not need soil contact, which changes the signs entirely — pellets rather than mud tubes — and changes the treatment options.
Formosan termites are not established in Virginia as of 2026. The nearest established zones are around Wilmington, North Carolina. Several Virginia pest control pages list them among species local homeowners face, which is worth knowing when you are reading quotes: if someone tells you your Virginia home has Formosan termites, ask what supports that identification.
Why the timeline matters more than the sighting
Colonies produce winged reproductives only once mature — generally after several years of establishment.
So a swarm in your living room in April is not the arrival of termites. It is the first visible evidence of something that has been consuming wood, out of sight, for years.
This single fact should shape how you read every other number on this page. The question is never "have they just started" but "how much has already happened where nobody has looked."
What you would actually see
Each of these has its own page, because each has a different set of look-alikes.
| Sign | What it usually means |
|---|---|
| Discarded wings on a windowsill | swarmers from a mature colony, possibly inside the structure |
| Mud tubes on foundation walls, piers, or joists | subterranean termites bridging soil to wood — pencil-width, brown, running vertically |
| Hollow-sounding wood when tapped | interior damage; the surface often remains intact |
| Bubbling or rippled paint | moisture, sometimes termite galleries just beneath |
| Stiff windows or doors | frames distorting as structural wood weakens |
| Frass — dry pellets | drywood termites, or more often in Virginia, carpenter bees |
The mud tube test: break a section out of the middle. If it is repaired within a few days, the tube is active.
Where they get in
Not randomly. Subterranean termites need a path from soil to wood, and the paths are predictable.
Wood-to-soil contact — deck posts set into the ground, fence rails against siding, buried form boards left after construction.
Foundation cracks and expansion joints, and the gaps around plumbing and utility penetrations.
Mulch and soil piled against siding, bridging above the foundation line.
Moisture from failed gutters, downspouts discharging at the wall, poor grading, crawl space humidity, or a slow leak inside a wall.
Debris under the structure — scrap lumber and cardboard left in a crawl space are both food and harbourage.
These are also what an inspector lists under "conducive conditions" on a wood-destroying insect report. They are cheap to correct and they are the reason treated houses get termites again.
What it costs, in outline
Treatment method drives the number, and the two mainstream approaches differ in mechanism as much as in price.
| Typical Virginia range | |
|---|---|
| Liquid barrier, average home | $1,000–$2,400 |
| Liquid, per linear foot in Virginia | $3.25–$17.25 |
| Bait system installation | $1,500–$3,500 |
| Bait system annual bond | $175–$500 |
| Annual termite bond generally | $200–$400, including inspection and re-treatment |
How the methods differ, and what drives the price →
Repair is separate and is not a pest control cost. Replacing a damaged sill plate or joist is carpentry, quoted by a contractor, and where framing is involved it commonly exceeds the treatment.
What this means for you specifically
If you own and live in the home
Damage accrues continuously, but nothing here requires action within hours.
Your action: get a licensed inspection from someone certified for wood-destroying pests — category 7b under 2VAC5-685-70 — before agreeing to any treatment. Ask what could not be accessed.
If you are selling under contract
You have a deadline that is not yours to set.
The standard Northern Virginia contract obligates the seller to furnish a wood-destroying insect report dated no more than 90 days before settlement, and to pay for treatment and for repair of damage the report identifies, with written evidence before settlement.
Your action: order the inspection early. Treatment is quick; structural repair depends on a contractor's calendar, and that is what moves settlement dates. The contract clause →
If you are buying
Read the seller's report properly — particularly the section listing what could not be accessed. A clean finding covers only what was reachable.
Your action: if the crawl space or a finished area was excluded and it concerns you, arrange your own inspection of that area. Reading the report →
If you rent
The structure is the landlord's responsibility through the duty to keep the premises fit and habitable under Va. Code § 55.1-1220. Your duty under § 55.1-1227 is to report promptly, and delay shifts added cost onto you.
Your action: notify the landlord in writing today, with photographs. Step by step →
Before you call: what costs what
An inspection and a treatment are two separate services with separate prices, and conflating them is the most common way people end up surprised by a bill.
| Typical Virginia range | What it produces | |
|---|---|---|
| Wood-destroying insect inspection and report | $65–$200 | the NPMA-33 form |
| General pest inspection | often free where the company expects to quote treatment | a verbal or written assessment |
| Termite treatment | $500–$2,000; more where damage is extensive | a treatment record |
| Structural repair | quoted by a contractor, frequently the largest of the three | an invoice, not a pest control document |
What is usually free: a quote for treatment, once a company has seen the problem.
What is usually not: the inspection report used in a real estate transaction, and any visit that produces a document rather than a price.
Ask which applies before you book. A company quoting one figure covering both inspection and treatment is not quoting what a sales contract or a lender requires.
Common misunderstandings
"I would have noticed." The surface of infested wood usually looks intact. Damage runs inside.
"They just arrived this spring." Swarmers indicate a colony mature enough to reproduce — years, not months.
"A brick house is safe." Brick is a veneer over a wood frame. Termites reach the frame.
"A new house is safe." New construction is treated during building, but treatment is not permanent and construction debris left in a crawl space is an invitation.
"One treatment is permanent." A liquid barrier is generally effective for several years, not forever. Bait systems are a monitored programme.
"A clean inspection means no termites." It means no visible evidence in accessible areas on that date.
What to ask an inspector
- Which species is this, and what supports that identification?
- Is the activity current or historical?
- What areas could you not access, and what would it take to reach them?
- What conducive conditions did you find, and which matter most?
- Liquid or bait for this house, and why that one?
- What is the treatment cost, quoted separately from the inspection?
- Is repair included, or is that a separate contractor?
- Under what name is your Virginia pesticide business license held?
The second and third questions are the ones people skip, and they are the ones that determine whether the quote you receive is proportionate.
What to have ready
Property address and year built, foundation type — crawl space, basement, or slab — square footage, what you have observed and where, whether there is prior treatment history or an existing bond, whether you are under contract, and any known moisture problems.
Frequently asked questions
When do termites swarm in Virginia? March through June, on warm days following rain. More on the season →
How fast does damage occur? Continuously. A mature colony feeds year-round, which is why the years before discovery matter more than the weeks after it.
Does homeowners insurance cover termite damage? Standard policies generally exclude it as a maintenance issue rather than a sudden loss. Read your policy rather than assuming.
Can I treat this myself? Products exist, but a subterranean colony lives outside the structure and a barrier has to be continuous to work. For anything involving a transaction, a treatment record from a licensed firm is what counts.
What is a termite bond? A contract, separate from the treatment, covering periodic inspection and re-treatment. Terms vary considerably — ask what it covers, what it excludes, and what renewal costs.
Verify before you pay anyone
VDACS maintains a public pesticide search at pesticidesearch.vdacs.virginia.gov and publishes an updated list of licensed pesticide businesses weekly. Wood-destroying pest control is category 7b under 2VAC5-685-70.
