Average Termite Treatment Cost: What Homeowners Pay in 2026

Termites cause over $5 billion in property damage annually in the U.S., and most homeowners insurance policies won’t cover it. If you’ve spotted mud tubes on your foundation, hollow-sounding wood, or winged swarmers indoors, you’re likely facing a treatment bill, and wondering what it’ll cost. The answer depends on your home’s size, the severity of the infestation, and the treatment method your pest control company recommends. This guide breaks down real-world pricing, explains what affects the final invoice, and helps you decide whether professional treatment is worth the cost.

What Does Termite Treatment Typically Cost?

Nationally, homeowners spend between $75 and $1,750 for termite treatment, with most paying around $600 to $850 for a typical single-family home. Spot treatments for localized infestations start at the low end, while whole-house chemical barriers or fumigation can push costs well above $2,000.

The national average sits near $621, according to recent industry data, but that figure reflects a wide range of scenarios. A small drywood termite colony in a garage might cost $300 to treat with localized borates, while a subterranean infestation beneath a 2,500-square-foot house could run $1,200–$2,500 for a full perimeter liquid treatment or bait system.

Most pest control companies charge by linear foot for perimeter treatments (typically $4–$16 per linear foot) or by square footage for fumigation (around $1–$4 per square foot). Always request an on-site inspection before committing, termite damage isn’t always visible, and estimates over the phone are often inaccurate.

Factors That Affect Termite Treatment Pricing

Infestation Severity and Property Size

A small, isolated colony discovered early costs far less to treat than a widespread infestation that’s been active for years. Severity determines whether you need a localized spot treatment or a full-scale barrier installation. Inspectors gauge this by checking crawl spaces, basements, attics, and visible structural members for mud tubes, frass (termite droppings), and damaged wood.

Property size directly impacts labor and material costs. A 1,200-square-foot bungalow with a simple slab foundation is cheaper to treat than a 3,000-square-foot two-story with a basement and attached garage. Perimeter treatments scale with the home’s footprint, more linear footage means more trenching, more chemical, and more time.

Accessibility matters, too. If your crawl space is tight, or your home sits on a hillside with limited access, expect higher labor charges. Contractors may need specialized equipment or additional crew members to reach all treatment zones.

Treatment Method and Termite Species

The type of termite determines which treatment methods work. Subterranean termites (the most common in the U.S.) nest in soil and require liquid termiticides or bait stations around the foundation. Drywood termites live inside the wood itself and may need localized injections, heat treatment, or whole-structure fumigation.

Treatment methods vary widely in cost:

• Liquid barrier treatments ($1,200–$2,500): Trenching around the foundation and injecting liquid termiticide into the soil. Effective for subterranean species. Lasts 5–10 years depending on the product.
• Bait systems ($1,500–$3,500): In-ground stations filled with slow-acting toxin that worker termites carry back to the colony. Requires ongoing monitoring and refills.
• Spot treatments ($200–$500): Drilling into infested wood and injecting foam or borate. Best for small, localized drywood infestations.
• Fumigation (tenting) ($1,200–$4,000+): Enclosing the entire structure and filling it with gas (usually sulfuryl fluoride). The only option for severe drywood infestations. You’ll need to vacate for 24–72 hours and remove plants, pets, and food.
• Heat treatment ($800–$2,500): Raising the interior temperature to 120–140°F to kill termites. Works for drywood species but requires specialized equipment.

Geography also plays a role. Termite pressure is higher in the Southeast and coastal regions, where subterranean species are more aggressive. Contractors in Florida, Louisiana, and Southern California typically see heavier infestations and may charge more for comprehensive treatments.

Cost Breakdown by Treatment Type

Here’s what you can expect to pay for the most common termite treatment methods in 2026:

• Liquid termiticide barrier: $1,200–$2,500 for a 2,000-square-foot home with a standard perimeter. Includes trenching, drilling, and chemical application. Popular products include Termidor, Taurus SC, and Altriset.
• Bait station installation: $1,500–$3,000 upfront, plus $300–$500 annually for monitoring and bait refills. Brands like Sentricon and Advance are common.
• Spot treatment (drywood): $200–$500 for localized infestations. Requires drilling into affected wood and injecting borate foam or dust.
• Whole-house fumigation: $1,200–$4,000+ depending on home size. Costs run about $1–$4 per square foot. A 2,500-square-foot home averages $2,500–$3,000.
• Heat treatment: $800–$2,500, depending on the number of rooms and accessibility. Less toxic than fumigation but not effective against subterranean species.
• Wood treatment (preventive borate application): $400–$1,200 for crawl spaces and attics. Often done during new construction or remodels.

Most pest control companies offer warranties ranging from one to five years, sometimes longer with annual inspections. A transferable warranty can add value when selling your home, especially in high-risk regions.

Additional costs may include structural repairs. If termites have damaged joists, studs, or flooring, you’ll need a contractor to sister new lumber, replace sheathing, or reinforce framing. Repair costs vary widely, $500 for minor cosmetic fixes, $5,000+ for structural work.

DIY vs. Professional Treatment: Which Is Worth It?

Big-box stores sell DIY termite treatments, liquid concentrates, bait stakes, and foam applicators, but they’re rarely a substitute for professional service, especially for active infestations.

DIY liquid treatments cost $50–$200 for a gallon of concentrate (enough to treat 50–100 linear feet). You’ll need a pump sprayer, trenching tools, and a drill to inject chemical into the soil and wood. The problem? Most homeowners can’t access all the critical zones, under slabs, inside block walls, or deep in crawl spaces, and incomplete treatments leave gaps for termites to bypass.

DIY bait stakes ($100–$300 for a 10-pack) are easier to install but require regular monitoring. If you don’t check them every few months, you won’t know if termites have taken the bait or bypassed your stations.

When DIY makes sense:

• You’ve confirmed a very small, localized drywood infestation (a few boards in a shed or detached garage).
• You’re applying preventive borate treatment to exposed wood during a remodel or new build.
• You’re supplementing professional treatment with your own monitoring.

When to call a pro:

• You’ve found mud tubes, swarmers, or extensive damage.
• You’re dealing with subterranean termites (the most destructive species).
• Your home has a crawl space, basement, or complex foundation that’s hard to access.
• You want a warranty or transferable treatment record for resale.

Professional companies have commercial-grade products, specialized equipment, and trained technicians who know where termites hide. They’ll also provide documentation for real estate transactions, many buyers request proof of treatment or an active termite bond. Platforms like HomeAdvisor and ImproveNet can help you compare local contractors and get multiple quotes.

Safety note: Termiticides are regulated pesticides. Always wear gloves, goggles, and a respirator when handling concentrates, and never apply near wells, ponds, or storm drains. If you’re uncertain about mixing rates or application techniques, hire a licensed pest control operator.

How to Budget for Termite Prevention and Maintenance

Treating an active infestation is just the first step. Long-term termite control requires ongoing prevention and annual inspections.

Most pest control companies offer annual termite inspections for $75–$150. If you’ve had treatment, many include the first year or two of inspections free as part of the warranty. Schedule inspections in spring, when termite swarmers are most active.

Preventive measures to budget for:

• Moisture control: Fix leaky gutters, regrade soil away from the foundation, and install vapor barriers in crawl spaces. Budget $200–$1,000 depending on the scope.
• Wood-to-soil contact removal: Replace wood siding, deck posts, or landscaping timbers that touch the ground. Termites need moisture and wood to thrive, eliminating contact points disrupts their access.
• Bait station monitoring: If you’ve installed a bait system, budget $300–$500 per year for a pest control company to check and refill stations.
• Borate treatment: Applying borate to exposed wood in attics and crawl spaces during remodels costs $400–$1,200 and lasts for years.

If you’re buying a home, always get a termite inspection before closing. Some lenders require it, and most sellers will credit repair costs if active infestations are found. Inspection fees are typically $75–$150 and can save you thousands in undiscovered damage.

In high-risk regions (coastal areas, the Southeast, parts of California), consider budgeting $500–$800 annually for ongoing monitoring and preventive treatments. It’s far cheaper than replacing joists, sills, or floor systems.
