Termite Treatment Cost: What U.S. Homeowners Actually Pay

By Andrea · August 2026

Termite damage costs U.S. homeowners an estimated $5 billion per year — and what you pay for treatment depends heavily on the method, termite species, home size, and where you live. This guide breaks down realistic cost ranges by treatment type and explains what drives the price up or down. For a full overview of control strategies, see our Termite Control hub.

How Much Does Termite Treatment Cost? A Realistic Range

For a typical single-family home, professional termite treatment runs anywhere from a few hundred dollars for a localized spot job to several thousand for whole-structure fumigation. The spread is wide because 'termite treatment' covers five genuinely different methods — each suited to different termite species and infestation levels. Learn more about how each method works at our Termite Control overview.

• Spot/localized treatment targets a confined infestation at lowest cost — typically best for early-stage drywood termites in accessible wood. See Termite Control for a full method comparison.
• Liquid soil treatment (termiticide barrier) is mid-range, priced per linear foot of foundation — the standard approach for subterranean termites. Full details on this method are covered under Termite Control.
• Bait station systems: ongoing annual subscription cost after initial installation — slow-acting but low chemical footprint.
• Tent fumigation: highest upfront cost, typically priced per thousand square feet — the only method proven to reach every corner of a drywood infestation.
• Orange oil / non-tent alternatives: mid-range, limited by penetration — suitable for specific drywood scenarios without vacating the home.

Costs also shift by region: treatment in Hawaii or Florida (high Formosan pressure, year-round activity) runs higher than in cooler northern states. Always get at least three quotes from licensed local pest-control companies before committing.

One Example Calculation (Estimates Only)

A 1,500 sq ft slab-on-grade home with an active subterranean infestation along roughly 120 linear feet of foundation might receive a liquid termiticide barrier treatment. At a typical industry range of $4–$7 per linear foot, the treatment alone could run $480–$840 before any inspection fees or follow-up visits. Add a pre-treatment inspection ($75–$150) and the total lands somewhere in the $550–$1,000 range for that specific scenario. Disclaimer: this is a rough illustration only.

What Drives Termite Treatment Cost Up or Down

No two jobs are priced the same. The biggest levers:

• Termite species: subterranean vs. drywood vs. Formosan — each requires a different method, and Formosan infestations are generally more aggressive and costly to address.
• Infestation severity and spread: a colony confined to one wall stud costs far less to treat than one that has moved through floor joists and subfloor.
• Home size and construction type: slab vs. crawlspace vs. basement changes how a liquid treatment is applied and priced (linear feet vs. square footage).
• Treatment method chosen: fumigation is priced per thousand cubic feet of space; liquid barriers by linear foot; bait stations by number of stations installed.
• Region and local labor market: treatment in high-cost metros or heavy-pressure states runs higher than rural areas with less competition.
• Warranty and ongoing monitoring: a one-time treatment costs less upfront than a termite bond (annual contract), but the bond covers retreatment if termites return.

Termite Inspection Cost: What to Expect Before Treatment

Most pest-control companies charge for a standalone WDO (Wood-Destroying Organism) inspection, though some offer free inspections as part of a treatment quote. Real estate transactions in most states require a licensed WDI/WDO report from a credentialed inspector — that document is separate from a quote and carries a fee. Inspection findings determine the method, scope, and ultimately the cost of treatment, so skipping it to save money usually backfires.

Treatment Methods: Where to Dig Deeper

Each method has its own cost structure, pros, cons, and termite-type fit. Rather than compress all of that here, the linked pages go into real price ranges, what's included, and which scenarios each method suits best.

Tent fumigation is the highest-cost method — priced per thousand square feet and the only approach proven to reach every corner of a drywood infestation. For full cost breakdowns including prep and hotel nights, see Termite Tenting And Fumigation Cost.

Liquid termiticide barriers are the primary method for subterranean termites including Formosan. For soil barrier costs broken down by construction type and linear footage, see the Liquid Termite Treatment Cost page.

Bait station programs like Sentricon involve an initial installation fee plus annual monitoring costs. The Sentricon treatment cost page covers how bait system pricing compares to a liquid barrier.

For drywood termites, the choice between spot treatment and full fumigation depends on infestation spread and accessibility. The Drywood Termite Treatment Cost page explains when each approach applies.

Homeowners who want to avoid vacating can explore Termite Treatment Without Tenting — a comparison of no-tent alternatives like orange oil, heat, and localized injections with honest notes on their limitations.

For small, accessible infestations, spot treatment is the lowest-cost entry point. See Termite Spot Treatment Cost for when this targeted approach is appropriate and what contractors typically charge.

Building new? Pre-treating soil and lumber during construction is almost always cheaper than post-construction treatment. Details are covered on the Termite Treatment For New Construction page.

DIY vs. Professional Treatment: The Honest Cost Trade-Off

DIY termite products — available at big-box stores and online — cost far less upfront than professional service. But the gap between product cost and actual protection is wide. Liquid termiticides sold to consumers are typically lower-concentration formulas; professional-grade termiticides (restricted-use in many states) require a licensed applicator. Tent fumigation using Vikane gas is not a DIY option under any circumstances — it is regulated, requires evacuation, and must be performed by licensed fumigators.

For minor, early-stage infestations in accessible wood, some DIY options exist — though their limitations are significant. The DIY termite treatment page covers what products are available without a license and where they realistically fall short.

How to Get the Most Accurate Price Estimate

Cost guides — including this one — give ranges, not quotes. The only way to know what your home will cost to treat is to get licensed local professionals on-site. A few practical steps that actually move the needle:

• Get at least three quotes from licensed pest-control companies in your area — pricing varies significantly even within the same zip code. For a broader overview of what to look for when hiring, see our Termite Control guide.
• Ask each company to identify the species and the extent of infestation in writing — this affects both method choice and price.
• Ask whether the quote includes a warranty or retreatment guarantee, and for how long — a lower bid without a bond may cost more if termites return within a year.
• Verify state licensing: each state has a pesticide regulatory agency that maintains a public license lookup — five minutes of checking protects you from unlicensed operators.
