Termite Treatment Cost: Liquid Barriers to Fumigation
Termite treatment ranges from $275 for a mild infestation to over $2,000 for whole-house fumigation, with most homeowners paying around $558 for a standard liquid barrier treatment.
What drives the price
Termite treatment cost depends mainly on infestation severity and treatment method. A localized, newly discovered infestation costs far less to treat than an established colony that has spread through a home's structure.
| Home size | Whole house treatment cost |
|---|---|
| 1,000 sq ft | $1,000 – $4,000 |
| 1,500 sq ft | $1,500 – $6,000 |
| 2,000 sq ft | $2,000 – $8,000 |
| 3,000 sq ft | $3,000 – $12,000 |
Treatment method changes the price a lot
Most pest control companies price liquid perimeter treatments by the linear foot of a home's foundation, typically $10 to $20 per linear foot. A standard liquid perimeter treatment on a 1,750 sq ft home runs around $680 on average.
Whole-house tenting or fumigation is reserved for severe drywood termite infestations that a perimeter treatment can't reach. It targets drywood termites specifically and isn't effective against subterranean or dampwood termites, which are more common in most of the U.S. and typically respond well to liquid barrier or baiting treatments.
What else affects the total
- Inspection fee — typically a separate line item, often waived if you proceed with treatment.
- Baiting systems — cost more upfront than liquid treatments but include ongoing monitoring, useful for prevention rather than an active infestation.
- Structural damage repair — treatment kills the termites but does not fix damage already done. Repairing joists, sills, or subfloor can add $1,000 to $10,000 or more, and should come from a structural assessment separate from the pest control company.
- Ongoing protection plans — many companies offer annual renewal contracts after the initial treatment, which is a recurring cost beyond the one-time treatment price.
Is your quote reasonable?
For a standard liquid perimeter treatment on an average-sized home, a quote in the $450 to $2,000 range is typical nationally. If a company recommends fumigation without first confirming a drywood termite species (versus the more common subterranean type), get a second opinion; a liquid barrier or baiting system may be sufficient and considerably less expensive. Since termites can compromise structural elements over time, see our foundation repair cost guide if an inspection turns up structural damage alongside the infestation.
