If you have spotted mud tubes on your foundation, hollow-sounding wood, or discarded wings near a windowsill, your stomach probably just dropped. Here is the honest answer upfront: termite treatment costs $500 to $3,500 for most US homes in 2026, depending on the method and the size of the infestation. Liquid chemical barriers run $1,000 to $3,500 for a typical home. Baiting systems cost $1,200 to $3,500 to install plus $300 to $500 per year for monitoring. Full tent fumigation, used for severe or whole-house infestations, costs $1,200 to $8,500. The earlier you catch an infestation, the cheaper the fix. Termites cause an estimated $6.8 billion in property damage across the US every year, according to the EPA, and most homeowners insurance policies do not cover that damage.
Why Termite Treatment Costs Vary So Much
You will get wildly different quotes from different pest control companies, and there are legitimate reasons for that. The main factors that drive cost are:
Species. There are two main species that matter in the US: subterranean termites and drywood termites. Subterranean termites live in the soil and build mud tubes into your home. They are the most widespread and responsible for the majority of structural damage. Drywood termites live inside the wood itself, require no soil contact, and are common in coastal and southern states. Formosan subterranean termites, found mainly in the Gulf Coast region, are the most aggressive and destructive of all, and treating them costs more.
Infestation size and extent. A localized colony in one wall is very different from a colony (or multiple colonies) that has spread through floor joists, wall studs, and structural beams. The more the termites have spread, the more treatment points are needed.
Treatment method. Spot treatment, liquid barriers, bait stations, heat treatment, and fumigation each have very different price points and appropriate use cases. More on this below.
Home size and foundation type. Treatment costs are often calculated per linear foot of your home’s perimeter. A 2,500 sq ft slab foundation home might have 200 linear feet to treat. A home with a crawl space or basement can cost more because of access and additional treatment points.
Location. Labor rates vary significantly by state, and so does the degree of termite pressure. Florida, Texas, Louisiana, and California see the highest activity, longest seasons, and often the highest treatment costs.
Termite Treatment Cost by Method
This is the most important comparison you need to make before you call a pest control company. Each method targets termites differently, and none of them is the right choice in every situation.
| Treatment Method | Typical Cost Range | Best For | Duration of Protection |
|---|---|---|---|
| Spot/localized treatment | $250 to $1,000 | Very small, localized colony | Short-term; follow-up likely needed |
| Liquid chemical barrier | $1,000 to $3,500 | Subterranean termites, whole-home protection | 5 to 10 years |
| Baiting system (Sentricon, Advance) | $1,200 to $3,500 install + $300 to $500/year | Ongoing monitoring, environmentally preferred | Annual renewal required |
| Tent fumigation (drywood termites) | $1,200 to $8,500+ | Whole-house drywood infestation | No residual protection |
| Heat treatment | $800 to $2,500 per area | Localized drywood infestation, no chemicals | No residual protection |
| Borate wood treatment | $1 to $2.50 per sq ft | Preventive on exposed wood, new construction | Decades if not washed away |
Liquid Chemical Barriers (Most Common)
This is the most widely used method for subterranean termites. A licensed technician trenches around your home’s foundation, drills through concrete where necessary, and injects a termiticide (commonly fipronil-based products like Termidor) into the soil. The chemical creates a treated zone. Termites passing through it carry the active ingredient back to the colony, eventually killing it.
Cost: $1,000 to $3,500 for a typical 1,500 to 2,500 sq ft home. Larger homes or homes with unusual foundation configurations can run $4,000 to $5,000. Most treatments come with a renewable warranty: you pay an annual inspection fee of $100 to $300 to keep the warranty active.
What to know: Termidor has an excellent track record and is approved for use by the EPA. The treatment is not instantaneous: it can take 30 to 90 days to fully eliminate a colony. Soil disturbance from landscaping, irrigation, or flooding can compromise the barrier over time.
Baiting Systems
Bait stations are installed in the ground around the perimeter of your home every 10 to 20 feet. Termites find the bait, feed on it, and bring it back to the colony. These systems work more slowly than liquid barriers but use far less chemical and are considered more environmentally friendly by the EPA.
Cost: $1,200 to $3,500 to install. Annual monitoring service runs $300 to $500 per year. The monitoring is not optional: bait stations must be checked regularly, bait replaced when consumed, and stations repositioned if needed. This is not a set-it-and-forget-it solution.
What to know: Sentricon and Advance are the two most widely used systems. They are excellent for active colonies and ongoing prevention, but they work more slowly. Some homeowners in high-pressure termite zones (Florida, South Carolina, Texas) combine liquid barriers with bait stations for belt-and-suspenders protection.
Tent Fumigation
If you have drywood termites throughout your home, fumigation is often the only way to guarantee full elimination. Your home is covered with a tent, and sulfuryl fluoride gas is pumped in. Everyone, including pets and plants, must leave for two to three days.
Cost: $1,200 to $3,500 for a smaller home (under 1,500 sq ft). A 2,500 sq ft home typically runs $2,500 to $5,500. Larger homes, homes with multiple stories, or homes in areas like Hawaii or South Florida where Formosan termites are severe can run $6,000 to $8,500 or more.
What to know: Fumigation kills every drywood termite in the building with no exceptions. But it leaves zero residual protection in the soil. You could have a new infestation start the next week. This is why many pest control companies recommend a follow-up liquid barrier or bait system after fumigation. You will also need to bag or remove all food, medications, and medical devices before treatment.
Heat Treatment
Heat treatment raises the internal temperature of infested wood to 120 to 140 degrees Fahrenheit, which is lethal to termites. It can be done room by room or for the whole house.
Cost: $800 to $2,500 per room or area. Whole-house heat treatment runs $10,000 to $20,000 in many markets, which is why it is typically reserved for specific sections of a home rather than whole-building use.
What to know: Heat treatment is chemical-free, which appeals to many homeowners. It penetrates into wall cavities and wood that liquid treatments cannot reach. However, it requires specialized equipment and trained technicians, it leaves no residual protection, and certain heat-sensitive materials in the treated area may be damaged.
Spot Treatment
For a very small, localized infestation caught early, a pest control company may be able to inject termiticide directly into a wall void or infested wood without treating the whole house.
Cost: $250 to $1,000 depending on access and number of treatment points.
What to know: Spot treatment is only appropriate when the infestation is genuinely contained and has been inspected by a licensed professional who can confirm its extent. If the infestation has spread beyond the treated area, you will likely need a more comprehensive treatment within a year.
Termite Treatment Cost by State
Termite pressure is not evenly distributed across the US. The USDA and pest control industry data place the highest risk zones in the Southeast, Gulf Coast, and parts of California.
| State/Region | Typical Liquid Barrier Cost | Notes |
|---|---|---|
| Florida | $1,500 to $4,500 | Highest termite pressure in the US; Formosan termites common |
| Texas | $1,000 to $3,500 | Active year-round in southern counties |
| Louisiana | $1,500 to $4,000 | Heavy Formosan pressure in New Orleans metro area |
| California | $1,200 to $4,000 | Drywood termites common in coastal areas |
| Georgia, South Carolina, North Carolina | $1,000 to $3,000 | High subterranean pressure |
| Arizona, New Mexico | $800 to $2,500 | Desert subterranean termites active |
| Midwest (Ohio, Indiana, Illinois) | $700 to $2,000 | Lower pressure but still common in older homes |
| Northeast (NY, NJ, PA, New England) | $700 to $2,200 | Eastern subterranean termites; lower activity than South |
| Pacific Northwest | $600 to $1,800 | Dampwood termites in wetter areas |
What a Termite Inspection Costs
Before any treatment, you need a termite inspection. Many companies offer free inspections, which is worth taking advantage of. Paid inspections run $75 to $150 for a standard home.
Real estate transactions in most states require a Wood Destroying Organism (WDO) report, sometimes called a termite letter or termite clearance letter. This costs $100 to $150 and must be performed by a licensed inspector. HUD requires a termite inspection for FHA loans in most termite-prone states, as outlined by HUD guidelines.
If you are buying a home, never skip the termite inspection even if it is not required. A home that looks perfect can have significant termite damage that only shows up when you probe the wood.
How to Spot Termites Before They Get Expensive
The most expensive termite treatments are the ones you need after years of hidden damage. These are the warning signs that warrant an immediate call to a licensed pest control company:
Mud tubes. Subterranean termites build pencil-width tubes of mud from the soil to your wood. You might find them on your foundation walls, crawl space joists, or even running up interior walls. Mud tubes are the single most reliable indicator of active subterranean termites.
Discarded wings. Termite reproductives (swarmers) shed their wings after finding a new colony site. Finding piles of small, equal-length wings near windows, doors, or light fixtures in spring or early summer means a swarm happened recently. This is one of the most common ways homeowners first discover an infestation.
Hollow or soft wood. Termites eat wood from the inside, leaving a thin shell on the surface. Tap on baseboards, floor joists, or window sills. A hollow sound is a red flag. Wood that crumbles when probed is a very serious sign.
Frass. Drywood termites push their fecal pellets (called frass) out of small holes in the wood. If you see small piles of what looks like sawdust or sand near wooden surfaces, that is a warning sign specific to drywood termites.
Sticking doors and windows. Termite damage and the moisture they introduce can cause wood to warp, making doors and windows stick in their frames.
Bubbling or uneven paint. This can indicate moisture damage from termites or, in some cases, direct gallery activity just beneath a painted surface.
The Real Cost of Waiting: Termite Damage Repair
This is the number that should motivate you to act fast. Termite treatment is cheap compared to repairing what they leave behind.
Structural wood damage repair costs vary widely but here are realistic numbers for common repairs:
- Floor joist replacement: $1,500 to $5,000 per affected area
- Sill plate replacement: $1,000 to $3,000
- Subfloor repair: $500 to $2,500 depending on square footage
- Structural beam replacement: $5,000 to $15,000+
- Significant structural damage affecting wall studs and framing: $10,000 to $50,000+
Most standard homeowners insurance policies do not cover termite damage, classifying it as a pest maintenance issue rather than a sudden, accidental loss. Some companies offer termite damage protection as an add-on endorsement, so check your policy carefully. The Insurance Information Institute recommends reviewing your policy annually and asking specifically about pest exclusions.
DIY Termite Treatment: What You Can and Cannot Do
You will find termiticide concentrates and bait stations at home improvement stores. Here is the honest assessment:
What DIY can handle: Prevention. Applying borate-based products (like Bora-Care) to exposed wood in your crawl space or garage during new construction or a renovation is something a reasonably handy homeowner can do. These products are highly effective at preventing termite entry into treated wood.
What DIY cannot handle reliably: An active infestation. Subterranean termite colonies can contain hundreds of thousands to several million workers, and they can spread through soil far beyond what a homeowner can map or treat effectively. Missing a section of the colony guarantees the infestation continues. For an active infestation, a licensed pest control professional is the right call every time.
If you do want to do preventive borate treatments yourself, the product must penetrate the wood, which means it needs to be applied to bare, unfinished wood. It will not penetrate through paint or stain.
How to Choose a Termite Control Company
Not all pest control companies are equal, and termite treatment is one of the areas where choosing wrong is expensive.
Verify the license. Every state requires pest control applicators to be licensed. Your state’s Department of Agriculture or a comparable regulatory agency maintains a license lookup. This is non-negotiable: never hire an unlicensed exterminator.
Get at least three quotes. Prices vary significantly. Make sure each quote specifies the treatment method, the product being used, what the warranty covers, and the annual renewal cost.
Ask about the warranty. A reputable company will offer a retreatment warranty, typically for one year, with the option to renew annually. Ask specifically: if termites return within the warranty period, will they retreat at no charge? If the termite damage worsens during the warranty period, what is their liability?
Check the National Pest Management Association (NPMA). Member companies have agreed to a code of ethics and receive ongoing training. You can find members at NPMA’s website.
Read reviews for patterns. A few negative reviews are normal. Look for patterns: companies with consistent complaints about missed infestations, upselling, or warranty disputes are worth avoiding.
Beware door-to-door termite inspectors. Legitimate pest control companies do door-to-door marketing, but so do scammers, especially in warm months when termite swarms are visible. Never let an uninvited inspector start poking around your home without verifying their license first.
Termite Prevention: What Actually Works
The best termite treatment is one you never need. These are evidence-based prevention steps recommended by the EPA and pest control professionals:
Fix moisture problems. Termites are attracted to moisture. Fix leaking pipes, improve drainage around your foundation, repair roof leaks promptly, and make sure gutters direct water away from the house.
Eliminate wood-to-soil contact. Wooden posts, deck supports, or framing that directly contacts soil give termites a direct highway into your structure. Replace wood-to-soil contact points with concrete footings or metal standoffs.
Keep mulch away from the foundation. Mulch retains moisture and organic material that attracts termites. Keep mulch at least 12 to 18 inches away from your foundation walls.
Store firewood away from the house. Firewood stacked against the house is essentially a termite welcome mat. Store it at least 20 feet from the house and off the ground.
Seal cracks in the foundation. Even small cracks in concrete can give subterranean termites a path into your structure. Inspect and seal foundation cracks as part of your annual home maintenance.
Get annual inspections. In high-termite-pressure states (Florida, Texas, Louisiana, Georgia, South Carolina, California), an annual termite inspection is worth the $75 to $150 it costs. In lower-pressure states, every two to three years is reasonable.

Termites are one of those problems where the longer you wait, the more expensive the solution gets. If you have any of the warning signs above, the cost of a professional inspection is nothing compared to what untreated damage can do to your home’s structure. Get the inspection, understand your options, and make a treatment decision before a manageable problem becomes a major structural repair.
