Spot and liquid-spray treatments run cheapest, bait systems and heat treatment land in the middle, and whole-house fumigation or tenting runs $1,500–$5,000 and can reach $8,000 for a larger home.
- ✓Most termite treatments run $229–$2,000, with a national average near $660.

What affects the cost?
- Treatment method: pesticide/liquid spray runs $150-$1,500, spot treatment $350-$1,000, bait systems $400-$3,000, heat treatment $1,300-$2,500, and fumigation/tenting $1,500-$5,000 (This Old House)
- Termite species: drywood and subterranean termite jobs run $225-$900, Formosan $250-$1,500, and dampwood up to $250-$2,500 (This Old House)
- Home size and perimeter length: Fixr prices liquid barrier treatment at $4-$14.50 per linear foot and whole-house methods (fumigation/tenting and heat treatment) at $1-$4 per sq ft of coverage, so a 2,000 sq ft home can run $2,000-$8,000 (Fixr)
- Infestation severity: light, localized activity costs far less than an established colony that needs whole-structure treatment
- Geographic location: states with heavier termite pressure such as Florida, Georgia, Alabama, and Louisiana tend to see higher prices (Thumbtack)
- Add-on costs: a termite inspection runs $75-$325 and a multi-year termite bond/protection plan adds another $500-$2,000 (This Old House)
Why does termite treatment cost so much?
Termite treatment is priced mainly by method and infestation size, running $229 to $2,000 for a typical project and averaging around $660 nationally (Fixr, Bob Vila, Thumbtack). A small, localized problem caught early can be handled with a $150–$1,500 spray treatment or a $350–$1,000 spot treatment, while a colony that’s spread through the structure needs a more involved approach like baiting or fumigation (This Old House). Whole-house fumigation and tenting sit at the top of the range, $1,500–$5,000 and up to $8,000 for a larger home, because the entire structure has to be sealed, gassed, and aired out over several days (Fixr, This Old House). Labor-intensive setup, licensed pesticide application, and the equipment needed to treat an entire perimeter or structure all add to the bill compared with a single-room spray.
What affects the cost?
Treatment method drives most of the price spread: pesticide spray runs $150–$1,500, spot treatment $350–$1,000, bait systems $400–$3,000, heat treatment $1,300–$2,500, and fumigation/tenting $1,500–$5,000 (This Old House). Fixr’s per-unit pricing tells a similar story, with liquid barrier treatment running $4–$14.50 per linear foot and whole-house methods (fumigation/tenting and heat treatment) running $1–$4 per square foot, which is why a 2,000 sq ft home can land anywhere from $2,000 to $8,000 depending on the method chosen. Termite species also matters: drywood and subterranean termites usually treat for $225–$900, while the more aggressive Formosan species can run $250–$1,500 and dampwood infestations up to $2,500 (This Old House). Infestation severity and home size compound these method costs, and location plays a role too, since states with heavier termite pressure like Florida, Georgia, Alabama, and Louisiana tend to see higher prices (Thumbtack). Finally, most jobs start with a termite inspection ($75–$325) to confirm species and scope before a treatment quote is finalized (This Old House).
How to lower your termite treatment cost
- Catch it early. A localized spot or spray treatment costs a fraction of what fumigation runs once termites have spread through the structure.
- Get an inspection first. A $75–$325 inspection confirms the species and scope, so you’re not paying for a broader treatment than you actually need.
- Compare treatment methods. Bait systems and liquid barriers are often cheaper than heat treatment or fumigation for moderate infestations, so ask your pest control company what the least invasive effective option is.
- Get multiple quotes. Per-linear-foot and per-square-foot rates vary by company and region, so two or three local estimates help you spot a fair price.
- Weigh a protection plan carefully. A termite bond or annual protection plan adds $500–$2,000 upfront but can be worth it in high-risk regions where reinfestation is common; in lower-risk areas, a one-time treatment may be enough.
Prices vary by region, termite species, and treatment method, so treat these figures as a planning baseline and confirm with a local, on-site quote before committing.

Frequently asked questions
How much does termite treatment cost on average?+
Most homeowners pay between $229 and $2,000, with a national average around $660. The final price depends heavily on the treatment method and how large the infestation is.
What's the cheapest way to treat termites?+
Spot treatment and pesticide spray are the least expensive professional options — pesticide spray runs $150–$1,500 and spot treatment $350–$1,000 — since they target a limited area rather than the whole structure.
How much does termite fumigation or tenting cost?+
Fumigation and tenting run $1,500–$5,000 for a typical home, and can climb toward $8,000 for a larger house, since the whole structure needs to be sealed and gassed.
Is heat treatment cheaper than fumigation?+
Heat treatment usually runs $1,300–$2,500, which is less than fumigation's $1,500–$5,000 range, and it skips chemical pesticides entirely, though it isn't always available for every infestation type.
Does the type of termite affect the price?+
Yes. Drywood and subterranean termite treatments tend to run $225–$900, while Formosan termites (a more aggressive species) can cost $250–$1,500 and dampwood infestations up to $2,500.
What else should I budget for besides the treatment itself?+
Plan for a termite inspection ($75–$325) before treatment, and consider a multi-year termite bond or protection plan, which typically adds $500–$2,000 on top of the initial treatment.

- Thumbtack — National average cost $694; range $380 to $1,268. Fumigation described as typically the most expensive treatment method. Higher costs noted in states with heavier termite prevalence, including Florida, Georgia, Alabama, and Louisiana.
Figures synthesized from four fetched sources whose reported national averages cluster in a similar band: Fixr ($680 avg; $450-$2,000 typical range; full range $300-$7,050), Bob Vila ($598 avg; $229-$967 range for professional treatment), Thumbtack ($694 avg; $380-$1,268 range), and This Old House ($700-$2,000 typical range, with a budget pesticide spray as low as $150 and severe fumigation cases reaching $5,000+). The published national average (~$660) is a rounded synthesis of the three sources that report a direct average (Fixr $680, Bob Vila $598, Thumbtack $694; mean ≈ $657). The typical range of $229-$2,000 covers standard spot, liquid-spray, and bait treatments (low end from Bob Vila's $229 professional-treatment floor, high end from This Old House's $2,000 typical-range ceiling); the wider project range of $150-$8,000 stretches to cover a budget pesticide-only job at the low end and whole-house fumigation/tenting of a larger home at the high end (based on Fixr's 2,000 sq ft whole-house figure). Excludes termite damage repair (wood or drywall replacement), which is a separate cost not covered by this guide.
