How Much Does Termite Treatment Cost?
Last updated: September 2026. Prices below are general US ranges for orientation, not quotes — always confirm current pricing with a licensed local company.
Short Answer
There is no single termite treatment price, because “treatment” covers everything from a small spot application to tenting an entire house. Many professional treatments fall around $700–$2,000, while whole-structure treatment can cost considerably more. As a rough orientation, a localized spot treatment tends to fall in the low hundreds, a whole-home liquid barrier or bait system in the low-to-mid thousands, and whole-home fumigation at the high end of that spread.
What you actually pay comes down to three honest variables: the treatment method, your home’s size and construction, and how far the termites have spread. The method itself is usually dictated by the termite species and the severity — which is exactly why confirming what you have comes before pricing anything.
Industry benchmark: A 2026 PCT survey of pest management professionals reported an average 2025 charge of about $1,100 for a typical post-construction termite treatment job. This is an industry benchmark, not a quote for a specific home or treatment method. Source: PCT State of the Termite Control Market, 2026.

Rough cost estimator
Answer four short questions for a ballpark range built from general US pricing. It estimates a range, not a quote, and never asks for your contact details.
The estimator gives a ballpark range from the general US figures in the table below. It is orientation only — prices vary by home, region, species, and severity, so always get written proposals from licensed local companies.
Professional Treatment Cost Ranges
These are broad US ranges drawn from aggregated industry pricing. Your quote depends heavily on region, home size, species, and severity, so treat these as orientation, not a promise.

| Method | Typical US range | Best suited to | Notes |
|---|---|---|---|
| Spot / localized treatment | ~$300–$1,000 | Small, contained, accessible infestation | Cheapest option; only works when activity is truly localized |
| Liquid soil barrier (whole-home) | ~$1,000–$3,200 | Subterranean termites around a foundation | Often priced at about $4–$16 per linear foot of perimeter |
| Bait-station system (install) | ~$1,000–$3,000 | Prevention + ongoing monitoring | Plus roughly $200–$500/year for monitoring |
| Whole-home tent fumigation | ~$2,000–$8,000 | Widespread drywood termites | About $1–$4 per sq ft; requires vacating the home for a few days |
| Heat treatment | ~$1–$4 per sq ft | Drywood termites, chemical-free option | Whole-home total depends on the area treated |
| Termite inspection | ~$75–$300 | Confirming activity before you spend | Often free when bundled with treatment or a warranty |
Ranges are general US orientation as of 2026 and vary widely by market. Liquid and bait work is frequently quoted per linear foot of the foundation perimeter, so a larger home costs more simply because there is more to treat.
Cost by Termite Type
Termite type doesn’t add a surcharge by itself — but it decides which methods can actually reach the colony, and that’s what moves the price. A liquid soil barrier can’t reach drywood termites living inside a beam, and fumigation isn’t the usual tool for subterranean termites in the soil.
→ Scroll the table sideways to see all columns.
| Termite type | Usual methods | Typical US range |
|---|---|---|
| Subterranean | Liquid soil barrier or bait system | ~$500–$2,500 |
| Drywood | Whole-home fumigation or heat (spot if truly localized) | ~$1,200–$4,000+ |
| Formosan | Liquid soil treatment, bait, or an integrated plan selected after inspection | Uses the applicable subterranean treatment range; species alone is not a surcharge |
Which type you have depends partly on region. Compare groups in subterranean vs. drywood vs. dampwood, and see the aggressive Formosan termite guide. Confirm the type before choosing a method — matching the two is where the money is saved or wasted.
Per Linear Foot vs. Per Square Foot
Two different pricing units show up in termite quotes, and knowing which one applies helps you sanity-check a bid:
- Per linear foot applies to perimeter work — liquid soil barriers and in-ground bait stations follow the outside edge of the foundation. Common figures land around $4–$16 per linear foot, so a house with more perimeter costs more.
- Per square foot applies to whole-structure work — fumigation and heat treat the volume of the home, commonly around $1–$4 per sq ft, so total floor area drives the number.
That’s why “how much per square foot” and “how much per linear foot” can both be right — they’re measuring different treatments. When you compare two quotes, check they’re pricing the same method and the same unit.
What Drives the Price
The same house on the same street can get very different quotes. The main reasons:
- Treatment method. The single biggest driver — and it’s usually dictated by the species and how far the colony has spread, not by preference.
- Home size and construction. More foundation perimeter or square footage means more product and labor. A slab, a full basement, or an attached garage all add complexity.
- Severity and spread. A small contained colony is a different job from termites tunnelling through multiple walls.
- Termite species. Subterranean termites typically mean soil treatment or bait; drywood termites can mean localized injection or whole-structure fumigation.
- Region. Location changes the likely termite type, inspection needs, treatment route, labor, and access conditions. Prices vary by region and market, so compare local written proposals rather than assuming one price applies everywhere. See our guides to California, Florida, Georgia, Hawaii, Louisiana, South Carolina, and Texas for state-specific species and inspection context.
- Warranty and monitoring. Ongoing annual fees (often a few hundred dollars) change the true multi-year cost, not just the upfront number. For the contract side of that cost, see our guide to termite bond coverage.
New Construction: Pre-Treatment Cost
If you’re building rather than treating an existing home, pre-construction termite treatment is a separate, much cheaper category. A licensed applicator treats the soil before the slab is poured, and borate-treated framing lumber is sometimes added. Because it’s done before the structure exists, it costs far less than retrofitting the same protection later.
Published per-square-foot figures for pre-treatment vary widely between sources, so treat any single number with caution and get a builder or operator quote. As an industry reference point, the same 2026 PCT survey above reported an average 2025 charge of about $816 for a typical pre-construction termite treatment job. Local codes, lender requirements, or builder programs may require termite protection in some areas, so ask what is included in the construction price.
DIY vs. Professional: Where the Money Actually Goes
DIY looks cheaper on the receipt, and sometimes it genuinely is. But the honest comparison isn’t “product price vs. company price” — it’s “what does each cost if it works, and what does it cost if it doesn’t?”
DIY tends to be cheaper when
- the job is prevention or monitoring, not an active emergency;
- you’re protecting bare, accessible wood you can reach;
- the situation is localized, clearly not structural, and low-risk;
- you’re comfortable following a pesticide label exactly.
Professional tends to be cheaper when
- the infestation is active, hidden, or possibly structural;
- a missed colony would keep eating and grow the repair bill;
- the job needs restricted products or precise application;
- there’s a deadline, or a prior DIY attempt already failed.
On the DIY side, the cost is mostly the product itself — the money pages walk through the main categories: treatment types compared, bait vs. liquid, and borate wood treatment. Always check current price and the label on the retailer’s own page.
A cheap product is not the same as a cheap solution. If a DIY treatment misses the real colony, the “saving” turns into a repair bill. Price the outcome, not just the receipt.
Why an Inspection Is the Cheapest First Dollar
It sounds backwards to pay for an inspection before treatment, but it’s usually the most cost-effective money you spend. Treating the wrong thing — surface-coating hidden damage, or applying a product that doesn’t match the species — wastes both the product and the time, while the real problem keeps going.
The math is stark: professional treatment commonly runs from a few hundred to a couple of thousand dollars, while structural damage from untreated termites can run into the tens of thousands, and homeowners insurance generally does not cover termite damage. A confirmed diagnosis first means you buy the right treatment once, instead of the wrong one twice.
Don’t Pay for Treatment You Haven’t Confirmed You Need
Before spending on any treatment — DIY or professional — make sure you actually have active termites and know roughly where. Get inspection findings in writing first. It’s common for a company to fold the inspection cost into treatment or a warranty, so asking costs you little.
If the activity is active, indoors, structural, or unclear, that’s a professional case from the start — see our mud tubes vs. old damage guide to tell active from old, and DIY vs. professional to confirm the path.
How to Get a Fair Quote
The best way to avoid overpaying is to get two or three quotes and compare the same scope, not just the headline number. Our checklist of questions to ask a termite company covers licensing, diagnosis, what the treatment does and doesn’t cover, warranty, and any recurring fees — so you’re comparing like with like before you sign.
Common Cost Questions
How much does termite treatment cost on average?
Many professional treatments fall around $700–$2,000, with whole-structure jobs costing more. A 2026 industry survey put the average 2025 post-construction treatment at about $1,100, but your price depends on method, home size, species, and severity — treat any single figure as a benchmark, not a quote.
How much is termite treatment per linear foot?
Perimeter treatments like liquid soil barriers and in-ground bait are commonly quoted around $4–$16 per linear foot of foundation, so a larger perimeter costs more. Ask each company to show the per-foot rate and the total feet they’re pricing.
How much does termite fumigation (tenting) cost?
Whole-home tent fumigation commonly runs about $1–$4 per square foot, or roughly $2,000–$8,000 for an average home, and requires vacating the house for a few days. It’s used mainly for widespread drywood termites. Heat treatment is a chemical-free alternative in a similar per-square-foot range.
Is there a no-tent option, and does it cost less?
For localized drywood activity, spot or heat treatments can avoid tenting, and a small spot job (about $300–$1,000) can cost less than whole-home fumigation. The catch is coverage: no-tent methods only work when the infestation is genuinely limited and reachable, so confirm the extent first.
What does a termite inspection cost?
A standalone inspection commonly runs about $75–$300, and many companies waive it when you book treatment or a warranty. Paying for a clear diagnosis first is usually the cheapest dollar you spend, because it stops you treating the wrong thing.
The Bottom Line on Cost
Termite treatment ranges from the low hundreds for a spot job to several thousand for whole-home work, driven by method, home size, species, and spread. The cheapest real path is almost always: confirm the problem first, match the treatment to the actual situation, and get the scope in writing. Start with our decision guide to find where you fit.
