Termite treatment costs range from roughly $100 for do-it-yourself products to $2,500 or more for professional whole-house fumigation, and where you land in that range depends on the method, the size of your home, the species, and how far the infestation has spread. The figures in this guide are typical 2026 ranges drawn from across the pest control industry, and they are estimates rather than quotes: regional pricing, the severity of your specific infestation, and local labor rates all move the number. What follows breaks the cost down by treatment method so you can see what each approach involves and budget realistically, and so you can weigh the do-it-yourself path against hiring a professional.
What Drives the Cost
The price of termite treatment is set by a handful of factors that interact, which is why quotes for the same house can vary widely. The treatment method matters most: a localized spot treatment costs a fraction of a whole-structure fumigation. The size of the home, usually measured in linear feet of foundation perimeter for soil treatments or square footage for fumigation, scales the cost directly. The termite species is a major driver, because subterranean termites are treated with soil barriers and baits while drywood infestations spread through a structure may require tenting. The severity and extent of the infestation determine how much of the structure needs treating, and regional pressure adds to the cost in high-activity states along the Gulf Coast and in the Southeast. Whether you do the work yourself or hire a licensed company is often the single largest swing in the total.
DIY Treatment Costs
Doing the treatment yourself is by far the cheapest option upfront, though it comes with a meaningful tradeoff in reliability. The DIY products homeowners use most, a liquid termiticide concentrate such as Taurus SC, a bait stake system such as Spectracide Terminate, or an aerosol foam for drywood galleries, generally cost between $100 and $300 to treat an average home, sometimes less for a spot treatment. The catch is success rate: DIY treatment works well for a correctly identified, accessible, and contained infestation, but its real-world success against a heavy or hidden infestation is lower than professional treatment, and a barrier with gaps in it can fail entirely. The product comparisons and per-treatment costs are laid out in the best termiticide guide, the best bait stations guide, and the best foam treatment guide. For most contained subterranean and drywood problems, the full DIY decision and method is covered in the how to get rid of termites overview.
Professional Treatment Costs by Method
Professional termite treatment typically runs between about $275 and $2,500 for most homes, with national averages commonly cited in the $575 to $850 range for an initial treatment. The price depends heavily on which method the infestation calls for, and the main options price out differently.
A liquid barrier treatment, in which a technician trenches the foundation and applies a termiticide such as a fipronil product to create a continuous soil barrier, is the standard for subterranean termites. It is commonly priced per linear foot of perimeter, often in the range of $4 to $16 per foot, which works out to roughly $500 to $2,500 for a typical home depending on perimeter length and product. A bait station system installed around the perimeter usually costs more upfront, often $1,500 to $3,500 to install, plus an annual monitoring fee in the range of $200 to $500 per year, because it is designed as an ongoing colony-monitoring program rather than a one-time barrier.
For drywood termites, a localized spot treatment of an accessible colony may run only $150 to $500, while whole-structure tent fumigation for a widespread infestation is the most expensive common option, generally $1,200 to $2,500 for an average home and rising toward $5,000 or more for large homes, often quoted at $1 to $4 per square foot. Heat treatment, a chemical-free alternative for localized drywood infestations, commonly costs $500 to $1,500 per room. A professional inspection itself typically costs $75 to $150, though many companies offer it free.
Cost Comparison at a Glance
| Treatment | Typical cost | Best for |
|---|---|---|
| DIY liquid, bait, or foam | $100 to $300 | Contained, accessible, correctly identified infestations |
| Professional liquid barrier | $500 to $2,500 | Subterranean termites, whole-perimeter protection |
| Professional bait system | $1,500 to $3,500 plus $200 to $500/year | Ongoing colony monitoring and elimination |
| Drywood spot treatment | $150 to $500 | Localized, accessible drywood colonies |
| Heat treatment | $500 to $1,500 per room | Chemical-free localized drywood control |
| Tent fumigation | $1,200 to $2,500, up to $5,000+ | Widespread drywood infestations |
| Annual termite bond | $150 to $500/year | Ongoing protection and retreatment guarantee |
Ongoing Costs and Termite Bonds
The cost of termite control does not always end with the initial treatment, and the ongoing component is worth budgeting for. Many homeowners in high-pressure regions carry a termite bond, an annual contract with a pest control company that covers monitoring and retreatment if termites return, typically $150 to $500 per year, with premium bonds also covering a capped amount of repair. Bait systems carry their own recurring monitoring fee. Whether ongoing coverage is worth the cost depends on local termite pressure: in the high-activity Southeast and Gulf Coast the math often favors a bond, while in low-risk northern climates the annual fee may exceed the expected risk.
Why Treatment Is Cheaper Than Waiting
The case for treating promptly is financial as much as structural, because the alternative is far more expensive and is not covered by insurance. Standard homeowners insurance excludes termite damage as a preventable maintenance issue, which means repair costs fall entirely on the owner, ranging from a few hundred dollars for cosmetic trim to tens of thousands for compromised load-bearing framing. The reasoning behind that exclusion, and the narrow exceptions to it, are covered in the guide on whether homeowners insurance covers termite damage. Against repair bills of that scale, both DIY treatment and a professional barrier are inexpensive, which is why catching and treating an infestation early is the cheapest decision available.
DIY or Professional: Matching Cost to Situation
The right spend depends on the infestation, not on the lowest sticker price. A small, accessible, correctly identified colony is a reasonable DIY project where the $100 to $300 product cost is money well spent. A widespread infestation, a Formosan colony, drywood termites scattered through finished walls, or any situation with active structural damage is where professional treatment earns its higher cost, because a failed DIY attempt on a serious infestation simply adds the cost of the eventual professional treatment to the damage that accrued in the meantime. The framework for deciding which situations warrant calling a professional is set out in the when to call a pest control professional guide.
