Termite Fumigation Cost Calculator (2026)
By Marcus Ellery, Pest Control Editor · Updated July 2026
Whole-house termite fumigation — tenting the structure and filling it with gas — costs about $1 to $4 per square foot, which works out to roughly $1,200 to $4,800 for most homes and $2,000 to $8,000 for an average 2,000-square-foot house. This is the big-gun treatment for a widespread drywood termite infestation, not a spot job, and the price is driven mostly by the volume of the home. Budget separately for a few nights out of the house and bagging or removing food. If you only need a localized fix, see our termite treatment page — this calculator is for full-structure tenting. Estimate yours below.
Estimate your cost
Tent fumigation treats drywood termites; it does not work on subterranean termites.
You must vacate for 24–72 hours; hotels average around $159 a night, plus deep-cleaning or replacing exposed items.

What drives your termite fumigation cost
- Home size: fumigation is priced by the enclosed volume, so bigger homes cost proportionally more at $1–$4 per square foot.
- Termite type: tenting targets drywood termites; aggressive Formosan colonies may need added liquid or bait treatment.
- Severity: a widespread, long-established infestation calls for a heavier gas dose and sometimes follow-up.
- Logistics: everyone (including pets and plants) must leave for 24–72 hours, adding hotel nights and food handling.
- Region and roof complexity: high-cost metros and tall or complex roofs raise the tenting labor.

Ways to save
- Get an inspection first — if the infestation is localized, a spot or micro treatment ($6–$8 per sq ft on a small area) may beat tenting.
- Seal food, drinks, and medicine in the fumigant-proof bags the company provides instead of throwing everything out.
- Book lodging early; a couple of nights at ~$159 each is a smaller add-on than replacing spoiled food and toiletries.
- Get 2–3 quotes — whole-house fumigation has one of the widest price spreads in pest control.
- Ask whether a warranty or re-treatment guarantee is included before signing.

Frequently asked questions
How much does termite fumigation cost in 2026?
Whole-house termite fumigation costs about $1 to $4 per square foot, or roughly $1,200 to $4,800 for most homes. An average 2,000-square-foot house runs around $2,000 to $8,000, and very large homes can reach $16,000.
Why is tent fumigation so expensive?
The whole structure is sealed under a tent and dosed with gas calibrated to its interior volume, so cost scales with home size. You also have to vacate for 24–72 hours, which adds hotel nights and food handling on top of the treatment.
Is fumigation the same as termite treatment?
No. Fumigation (tenting) is a whole-structure method for widespread drywood termites. Localized problems — or subterranean termites, which tenting does not reach — are handled with cheaper spot, liquid-barrier, or bait treatments. See our termite treatment calculator for those.
How long do I have to leave the house for fumigation?
Plan on being out for 24 to 72 hours while the home is tented, fumigated, and aired out. Food, drinks, and medicines must be removed or sealed in the special bags the company supplies.
