Termite Treatment Cost Calculator (2026)

Checked 14 October 2026: HomeAdvisor puts one professional treatment at $263 to $1,033 (average $621) and This Old House says treatment usually costs $700 to $2,000. For a whole house, HomeGuide gives $500 to $2,000 or more for a liquid soil barrier, $1,000 to $2,500 for a bait station system plus $200 to $400 a year to monitor it, and $2,000 to $8,000 to tent an average-sized home. Orkin's own prices run from $250 for a spot treatment to $5,000 or more for a whole-home solution. Termite control and termite treatment are the same service in these figures.

Two publishers print a single national average, and both describe one treatment job: HomeAdvisor $621 (from its survey of customers' project costs) and Thumbtack $694 (a single treatment from Thumbtack data, checked 13 October 2026; recurring treatment is extra). Neither is the cost of a full liquid or bait installation, which HomeGuide puts at $500 to $2,000 or more and $1,000 to $2,500.

HomeGuide gives $3 to $20 per linear foot for chemical soil treatment and $7 to $12 per linear foot for bait stations; HomeAdvisor gives $3 to $16 per linear foot for chemical termiticide and $8 to $12 per linear foot for bait. A square 2,000 sq ft footprint is about 179 linear feet, which puts liquid at $537 to $3,580 and bait at $1,253 to $2,148 on HomeGuide's rates (our arithmetic). The calculator above takes your own footage.

Only the whole-structure methods are priced by floor area. HomeGuide gives $1 to $4 per sq ft for tent fumigation ($2,000 to $8,000 for a 2,000 sq ft home; Bob Vila gives the same rate) and $1 to $3 per sq ft for tented heat. Micro treatments for small, early infestations run $6 to $8 per sq ft of treated area. Liquid barriers and bait stations are priced per linear foot of foundation, not per square foot.

On HomeGuide's rates for a 179 ft perimeter (a square 2,000 sq ft home), liquid costs $537 to $3,580 to install, or $1,887 to $8,080 over ten years if you renew a contract each year at $150 to $500 a year. Bait costs $1,253 to $2,148 to install and $3,053 to $5,748 over ten years with $200 to $400 a year monitoring from year 2. Corteva says Sentricon costs about a dollar a day to keep in place once installed. Mississippi State University Extension says some liquid treatments last 12 years or longer, while bait protects for as long as the stations are serviced, at least yearly. All totals are our arithmetic on the published rates.

They measure different jobs. HomeAdvisor's $263 to $1,033 and Thumbtack's $380 to $1,268 describe one treatment job from their own customers, which includes spot work and single visits. HomeGuide's $500 to $2,000 or more is a whole-home liquid treatment and its $2,000 to $8,000 is whole-home tenting. Orkin's $250 to $5,000 or more runs from its own spot treatments to whole-home work. We show each figure as its source states it rather than averaging them into one number.

Usually not. The standard ISO homeowners form (HO 00 03) does not insure loss caused by insects, so ordinary termite damage and the cost of treating it fall on the owner. That form does carry two narrow exceptions: an abrupt collapse caused by insect damage that was hidden from view and not known to you before the collapse, and an ensuing loss that another part of the policy covers, such as a fire. Carriers that use their own forms may word this differently, so read yours.

What most people call a termite bond is a renewable service contract. HomeGuide puts one at $500 to $2,500 for the first year and $150 to $500 a year to renew (compiled estimates). Some contracts cover retreatment only; others also pay for repairs up to a cap the contract states. No regulator or operator publishes a re-infestation rate, so we do not put a break-even figure on it.

HomeGuide puts a termite inspection at $0 to $250 for most homes, $100 to $325 for a real estate transaction and $50 to $200 for a VA or FHA loan; This Old House gives $75 to $325. Orkin says it offers free termite inspections in many areas, and Terminix says your first termite inspection is free; a free inspection from a company that sells treatment is part of a sales visit, so read the report before you accept the quote that comes with it.

No university extension, EPA or NPMA source we could find publishes a success rate for retail termite products against an active infestation, so we do not quote one. The EPA says that in most cases termiticide application can only be properly performed by a trained pest management professional, and Mississippi State University Extension calls termite control "not a do-it-yourself job". DIY makes sense for prevention and moisture control.

Mississippi State University Extension says some liquid termiticide treatments last 12 years or longer but can fail sooner, and that bait can control termites indefinitely while the contract is kept and the stations are checked at least yearly. BASF says Termidor can protect for up to 10 years (its EPA label states no period). Fumigation and heat kill the termites present but leave no residual protection (UC IPM Pest Notes).

HomeGuide and Bob Vila both put tent fumigation at $1 to $4 per sq ft, which is $2,000 to $8,000 for a 2,000 sq ft home; This Old House gives $1,500 to $5,000. The gas is sulfuryl fluoride, sold as Vikane. Fumigation treats drywood termites in the structure; subterranean colonies in the soil need a liquid barrier or bait.
