Average termite treatment cost
The 2026 national average sits at roughly $1,500 across all methods and all severities. The mean is dragged up by a small number of severe drywood fumigation cases and dragged down by a larger number of cheap inspections and spot treatments. The page below breaks the average down by method, region, severity, and home size so you can see where your situation sits in the distribution.

Section C / Method averages
Average cost by treatment method (2026)
Method averages are weighted means across 2026 aggregated quote data. The right-hand column is the most common note relevant to that method's cost profile.
| Method | Average |
|---|---|
| Liquid barrier (Termidor SC) | $1,800 |
| Bait stations (Sentricon) | $2,200 install + $400/yr |
| Tent fumigation (Vikane) | $3,200 |
| Heat treatment | $1,500 |
| Spot treatment | $475 |
Section D / Regional averages
Average cost by US region (2026)
Regional averages assume a typical 2,000 sq ft home with moderate severity using the dominant local method. Southeast and West Coast both run meaningfully above the national mean. Midwest is the lowest US region. Hawaii is the highest US state on island pricing and Formosan pressure combined.
| Region | Average |
|---|---|
| Southeast (FL, GA, AL, SC, NC, LA, MS) | $1,950 |
| Southwest (TX, AZ, NM) | $1,650 |
| West Coast (CA, OR, WA) | $2,180 |
| Midwest (OH, IL, IN, MO) | $1,420 |
| Northeast (NY, NJ, PA, CT) | $1,650 |
| Hawaii | $2,580 |
Section E / Severity averages
Average cost by infestation severity (2026)
Severity is the single biggest swing in the distribution. The same home can sit anywhere on this table depending on whether the infestation was caught at annual inspection or noticed after structural damage is already present. This is why annual inspection ($75 to $300) is the highest-leverage spend in the entire termite cost stack.
| Severity | Average range |
|---|---|
| Mild (caught early, localized) | $400-$800 |
| Moderate (confirmed colony, full treatment) | $1,000-$2,500 |
| Severe (structural damage, drywood, large home) | $3,000-$8,000+ |
Section F / Home-size averages
Average cost by home size (2026)
Home-size averages assume a moderate severity subterranean colony treated with the regional standard method (liquid or bait) in a baseline-region market. Multi-story homes, irregular footprints, and luxury builds with extensive crawlspace or basement add 15 to 25 percent above these averages.
| Home size | Average |
|---|---|
| 1,000 sq ft | $700 |
| 1,500 sq ft | $1,100 |
| 2,000 sq ft | $1,500 |
| 2,500 sq ft | $1,900 |
| 3,000 sq ft | $2,300 |
Section G / How averages mislead
What the national average hides
The published $1,500 national average is a mean. It is built from a quote distribution that runs from $300 (spot work on a small confirmed pocket) to $12,000 (large luxury Florida home with active Formosan colony and structural damage requiring fumigation plus liquid barrier plus repair). Reading the mean as your expected cost ignores most of the dispersion.
The single biggest variance driver is when the infestation is caught. A homeowner who detects mud tubes at annual inspection and books a spot treatment pays $300 to $800. The same homeowner who notices hollow-sounding floor joists two years later pays $2,500 to $6,000 plus repair. Same home, same colony species, different point on the severity curve. The mean is what happens when both of those homeowners show up in the same quote database.
The second biggest driver is method, which is set by species. A Florida homeowner with drywood termites cannot use liquid barrier or bait; the colony lives in the wood members above the soil line. Tent fumigation is the only reliable method, and tent fumigation costs roughly 2x the average subterranean liquid treatment. Region-by-region averages reflect this method mix, which is why the Southeast average ($1,950) is well above the Midwest average ($1,420) even before adjusting for labor cost or pressure.
The third driver is operator pricing strategy. National chains (Orkin, Terminix, Truly Nolen, Aptive) tend to quote at the upper end of the local price range. Local licensed operators are often 15 to 25 percent below national chains for equivalent chemistry and equivalent warranty. The same job can have a 30 percent spread across three operators in the same zip code. Getting two or three quotes is genuinely the highest-leverage move a homeowner can make for their specific number, more useful than any published average.
Use the averages on this page as a sanity check. If a quote comes in at 2x the regional average for your home size and severity, that is a flag to get a second quote, not necessarily a sign that the first quote is wrong. If a quote comes in at half the regional average, that is also a flag, because cheap quotes often reflect chemistry substitution (generic fipronil instead of Termidor SC) or shorter warranty terms.
Section H / FAQ
Common questions about the averages
What is the average termite treatment cost in 2026?+
Averaged across all methods, all severities, and all US regions, the typical termite treatment costs roughly $1,500 in 2026. The all-method national average from HomeGuide aggregated quote data sits near $575 for spot or single-visit work and rises to $1,800 to $2,200 for full liquid or bait installs. The average is heavily influenced by the mix of mild caught-early cases (which pull the number down) and severe cases (which pull the number up).
What is the average cost by treatment method?+
Liquid barrier (Termidor SC) averages $1,800. Bait stations (Sentricon) average $2,200 install plus $400 per year monitoring. Tent fumigation averages $3,200. Heat treatment averages $1,500. Spot treatment averages $475. These are national averages aggregated from HomeGuide, HomeAdvisor, and Angi 2026 quote data. Regional variation moves any individual number by 15 to 30 percent.
Why is the average so different from the typical price?+
The average is dragged up by a small number of severe cases (severe drywood fumigation runs $5,000 to $8,000) and dragged down by a larger number of cheap spot treatments and inspections. The median caught-early subterranean liquid barrier sits at roughly $1,500, which is closer to what most homeowners with active confirmed termites actually pay. The mean is higher because the distribution has a long right tail.
What is the average termite treatment cost by region?+
Southeast US averages $1,950 (Florida, Georgia, Alabama, South Carolina, North Carolina, Louisiana, Mississippi). Southwest averages $1,650. West Coast averages $2,180. Midwest averages $1,420. Northeast averages $1,650. Hawaii averages $2,580. Regional differences reflect a combination of labor cost, termite pressure (Southeast and Hawaii are highest), and whether tent fumigation is part of the local treatment mix.
What is the average cost by home size?+
1,000 sq ft averages $700. 1,500 sq ft averages $1,100. 2,000 sq ft averages $1,500. 2,500 sq ft averages $1,900. 3,000 sq ft averages $2,300. These averages assume a typical mix of subterranean liquid and bait treatments at moderate severity in a baseline region. Multi-story and luxury homes with extensive crawlspace or basement run 15 to 25 percent above these averages.
What is the average cost by infestation severity?+
Mild severity averages $400 to $800 (small confirmed infestation, spot or localized treatment). Moderate severity averages $1,000 to $2,500 (full liquid barrier or bait install for a confirmed subterranean colony). Severe severity averages $3,000 to $8,000 or more (tent fumigation, structural damage, multiple species, or large luxury home). Mild caught-early is by far the cheapest path and is the case for annual inspection.
Are the published averages accurate for what I will actually pay?+
Published averages are accurate as central tendency across the national quote dataset but should not be treated as a price you can confidently expect. Quote dispersion is wide. For the same 2,000 sq ft home in Florida, a homeowner can plausibly receive quotes from $700 to $4,500 across three operators. The right use of averages is as a sanity check on a specific quote, not as a substitute for getting two or three local quotes yourself.
