Termite Fumigation Cost per Square Foot, Explained
Last updated: October 30, 2026 · Prices checked October 30, 2026
Termite fumigation cost per square foot runs $1–$4 according to Angi — the number to check when a fumigator hands you a quote and a square footage that may or may not be your home's. Here's how the rate is built, how to verify your quote in two minutes, and why two houses with identical floor plans can legitimately get different per-square-foot results.
Fumigation rate: $1–$4 per sq ft · or $5–$20 per linear foot · typical totals $2,000–$5,000 (avg ~$3,000).

Worked examples at the published rate
| Home size | At $1–$4 / sq ft |
|---|---|
| 1,200 sq ft | $1,200 – $4,800 |
| 1,800 sq ft | $1,800 – $7,200 |
| 2,000 sq ft | $2,000 – $8,000 |
| 2,500 sq ft | $2,500 – $10,000 |
| Heat treatment (alternative), per sq ft | $1–$3 / sq ft |
Notice the tension: strict per-foot math on a 2,500 sq ft home tops out at $10,000, yet Angi's typical whole-home total is $2,000–$5,000. That's because the per-foot figure is a rate card, and the actual quote is computed from the volume under the tent — then rounded by market competition. Use the rate to sanity-check, and the typical band to judge the final total. Run your own size in the treatment estimator (fumigation mode).
Why your per-square-foot quote isn't the neighbor's
- Volume, not area. The fumigant dose is calculated on cubic volume: vaulted ceilings, two-story entries and tall roofs mean more gas for the same footprint.
- Tarp difficulty. Complex rooflines, chimneys, attached structures and tight lot lines all add labor to sealing the tent.
- Target organism and dose. Drywood termites are the standard tenting target; heavier infestations and certain beetles need longer exposure.
- Market. Florida's dense fumigation market prices differently from a state where two companies cover a whole region.
Checking a quote in two minutes
- Divide the quote by your home's true heated square footage. Inside $1–$4? Proceed. Outside? Ask why, in writing.
- Compare the total against the typical $2,000–$5,000 band for a mid-size home — totals matter more than rates.
- Confirm what's included: prep crew work, re-entry certification, any warranty, and whether a preventive treatment or bond is bundled (fumigation leaves no residual protection — see fumigation cost).
- Get the second quote. Fumigation is a four-figure, plan-ahead job — never an emergency purchase.
Frequently asked questions
What is the average fumigation cost per square foot?+
$1–$4 per square foot for tent fumigation (Angi). Heat treatment, the main alternative, runs $1–$3 per square foot.
Why is my quote priced per linear foot instead?+
Some fumigators quote $5–$20 per linear foot of structure perimeter. Convert before comparing: divide the total by your square footage and check it against the $1–$4 band.
Does a bigger home always cost more per square foot?+
Usually the opposite: fixed costs (crew, tent, setup) spread over more area, so large homes often land at the lower end of the per-foot band — though very large homes (3,000+ sq ft) still total $3,000–$12,000+.
Is fumigation priced differently in Florida?+
Florida's high drywood pressure and competitive fumigation market keep typical totals inside the national band, but Angi's Florida data shows tenting reaching $6,720 for larger homes. See our Florida breakdown for the state picture.
