Termite Treatment Cost Estimator
Enter your foundation length or square footage, choose a treatment, and get a price range built from published 2026 price guides. It won't replace three real quotes, but it will tell you which quote doesn't add up.
The short version
Liquid and bait treatments are priced by the linear foot of foundation: about $3 to $16 a foot for liquid and $8 to $12 for bait, per HomeAdvisor's 2026 guide. Tenting runs about $1 to $4 per square foot and whole-house heat about $1 to $3, per Angi. Enter your numbers below for a range.

Estimate your treatment cost
Measure around the outside of your foundation for the most accurate number. If you only know your square footage, the estimator will approximate the perimeter.
Pick a treatment and enter your foundation perimeter or square footage. Liquid and bait jobs are priced by the foot of foundation; tenting and heat by the square foot.
Where the numbers come from
The estimator multiplies your size by these published ranges. We update them when the guides do.
| Treatment | Priced by | Range | Source |
|---|---|---|---|
| Liquid soil barrier | Linear foot of foundation | $3 to $16 | HomeAdvisor, June 2026 |
| Bait system | Linear foot of foundation | $8 to $12, plus yearly monitoring | HomeAdvisor, June 2026 |
| Tenting (fumigation) | Square foot of interior | $1 to $4 | Angi, August 2026 |
| Whole-house heat | Square foot | $1 to $3 | Angi, August 2026 |
| Spot treatment | The job | About $200 to $900 | Our cost guide |

Measuring your foundation
For liquid and bait jobs, the number that matters is the linear feet of foundation: the distance all the way around the outside of the house where it meets the ground. A tape measure and ten minutes will get you close. Include attached garages and porches that sit on their own foundation, since those usually get treated too.
The estimator can guess your perimeter from square footage by assuming a square, one-story house. Real houses are rarely square. A long ranch or an L-shaped plan has more foundation per square foot than a compact two-story, which is why a two-story house can cost less to treat than a smaller ranch. Measure if you can.
What the estimator can't see
A price range is a starting point. These things move a real quote, and the estimator can't know about them:
- Concrete to drill. Slabs, patios, driveways and porches along the foundation have to be drilled and injected, which adds labor.
- Access. Tight crawlspaces, finished basements and wells or cisterns near the house can complicate or limit treatment.
- The termite. Formosan termites often get a more involved plan, and drywood termites need a different method altogether.
- Where you live. Labor costs and competition vary a lot from one city to the next.
- The warranty. A quote that includes repair coverage, or more inspections, will cost more than retreatment-only.
Using your estimate
Take the range to your quotes. If a quote lands well above it, ask what's driving the price; there may be a good answer, like a lot of concrete or a Formosan plan. If a quote lands far below it, ask what's being left out; a partial treatment or a spot job can look cheap. Either way, compare quotes for the same method and the same areas. Our questions to ask a termite company help, and the termite bond calculator runs the numbers on renewals.
Questions people ask
How much does termite treatment cost for a 2,000 square foot house?
It depends on the method. For liquid or bait, the price follows the foundation length: about 180 feet for a square 2,000-square-foot house, which works out to roughly $550 to $2,850 for liquid at HomeAdvisor's 2026 rates. Tenting at Angi's $1 to $4 per square foot would be about $2,000 to $8,000.
Why is termite treatment priced per linear foot?
Liquid barriers and bait stations go around the outside of the foundation, so the work and the product scale with the length of that line, not with the number of rooms.
Is the estimate a quote?
No. It's a range built from national price guides. Real quotes depend on concrete, access, the termite and local labor costs, so get at least three written quotes for the same method.
