Termite Treatment Cost: Inspection Prevention and Extermination
What Does Termite Treatment Cost in 2026?
Termites cause more structural damage to American homes than fires, floods, and windstorms combined. They work silently, eating wood from the inside out, and by the time you see the signs — mud tubes, hollow-sounding wood, discarded wings — they’ve been at it for months or years. The good news: treatment works, and catching them early saves thousands in repair bills.
Most homeowners pay $500 to $2,500 for liquid barrier treatment or $1,200 to $3,500 for tent fumigation. The method, home size, severity of the infestation, and your region all affect the final bill. Here’s exactly what each treatment involves and what you should expect to pay.
Termite Treatment Cost by Method
| Treatment Method | Cost Range | Best For | Duration of Protection |
|---|---|---|---|
| Liquid Barrier (Termidor, Taurus) | $500–$2,500 | Subterranean termites | 5–10 years |
| Bait Stations (Sentricon, Advance) | $1,500–$3,500 first year | Ongoing monitoring | Continuous (annual renewal) |
| Tent Fumigation (Vikane gas) | $1,200–$3,500 | Drywood termites | No residual protection |
| Spot/Localized Treatment | $200–$900 | Small, isolated colonies | Varies |
| Heat Treatment | $800–$2,500 | Drywood termites, chemical-free | No residual protection |
| Borate Wood Treatment | $1,000–$2,500 | New construction, prevention | Lifetime of treated wood |
The right method depends on which termite species you have. Subterranean termites live in the soil and enter through the foundation — liquid barriers and bait stations target them. Drywood termites live inside the wood itself and require fumigation or heat treatment.
Liquid Barrier Treatment: The Most Common Fix
About 80% of termite treatments in the U.S. use liquid termiticide applied around the foundation. The exterminator trenches along the perimeter of your home, drills through concrete slabs where needed, and applies product like Termidor SC (fipronil) or Taurus SC into the soil.
How Pricing Works
Most companies price liquid treatments by linear foot of foundation perimeter:
- $4 to $16 per linear foot — typical range
- 1,200 sq ft home (~140 linear ft): $560–$2,240
- 2,000 sq ft home (~180 linear ft): $720–$2,880
- 2,500 sq ft home (~200 linear ft): $800–$3,200
Factors that push costs higher: slab foundations requiring drilling, heavy landscaping that complicates trenching, and wells or water features that restrict chemical application. Some companies offer a flat rate based on home size instead of per-linear-foot pricing.
How Long It Lasts
Modern termiticides like Termidor last 5 to 10 years in the soil. After that, you’ll need re-treatment. Most pest control companies offer annual inspection contracts ($100–$300/year) that include re-treatment if termites return — worth it in high-risk areas like the Southeast, Gulf Coast, and Pacific Coast.
Bait Station Systems
Bait stations (Sentricon, Advance, Hex-Pro) use a different approach. Plastic stations are installed every 10 to 15 feet around your foundation, containing wood or cellulose bait laced with a slow-acting insect growth regulator. Termites feed on the bait, carry it back to the colony, and the colony collapses over weeks to months.
| Cost Component | Price Range |
|---|---|
| Initial installation (20–30 stations) | $1,500–$3,500 |
| Annual monitoring & bait renewal | $300–$500/year |
| Combined first-year cost | $1,500–$3,500 |
Bait systems cost more over time because of annual monitoring fees. Over 5 years, you might spend $3,000 to $5,500 total. But they’re less disruptive to install, use far less chemical, and work well on properties where liquid treatment isn’t practical — homes near water, heavy hardscaping, or sensitive landscaping.
Tent Fumigation: When You Need the Big Gun
Tenting is exactly what it sounds like. A crew wraps your entire house in tarps and pumps it full of Vikane gas (sulfuryl fluoride). The gas penetrates every piece of wood in the structure, killing drywood termites wherever they’re hiding.
What Tent Fumigation Costs
- Small home (under 1,500 sq ft): $1,200–$2,000
- Average home (1,500–2,500 sq ft): $2,000–$3,000
- Large home (2,500+ sq ft): $2,500–$3,500+
What to Expect
You’ll need to vacate the house for 2 to 3 days. Remove all food, medicine, plants, and pets — including fish tanks. The fumigator seals the house, treats it, aerates it, and tests the air before you return. It’s disruptive but effective; fumigation kills 99%+ of drywood termites throughout the structure.
The downside: zero residual protection. Drywood termites can re-infest after fumigation since there’s no lasting chemical barrier. In heavy drywood termite areas (Southern California, coastal Florida, Hawaii), some homeowners fumigate every 5 to 7 years as maintenance.
Termite Inspection Costs
Many pest control companies offer free termite inspections, especially if they’re hoping to land the treatment job. Standalone inspections from independent inspectors cost $75 to $150.
If you’re home buying guide, a termite inspection (also called a WDI or Wood Destroying Insect report) is often required by the lender. In many states, the seller pays for this inspection. Your real estate agent should clarify who covers it — check your purchase contract. A clean WDI report gives lenders confidence in the property’s structural integrity, which matters for your mortgage approval.
Termite Damage Repair Costs
Treatment kills the termites. Repair fixes what they ate. Depending on how long the colony has been active, repair costs can dwarf treatment costs:
| Damage Level | Typical Repairs | Cost Range |
|---|---|---|
| Minor (cosmetic) | Patching drywall, filling wood, repainting | $500–$1,500 |
| Moderate | Replacing trim, subfloor sections, door frames | $2,000–$5,000 |
| Severe (structural) | Sister joists, replace beams, foundation repair | $5,000–$20,000+ |
This is why early detection matters. Annual inspections cost $100 to $300. Catching an infestation in year one versus year five can mean the difference between a $500 repair and a $15,000 structural rebuild. Your home equity takes a real hit when structural damage shows up on an appraisal.
Signs You Have Termites
Most homeowners discover termites when damage is already visible. Here’s what to look for during your own walk-around:
- Mud tubes on foundation walls, piers, or crawl space — pencil-width tunnels made of soil and termite saliva
- Hollow-sounding wood when tapped, especially baseboards, door frames, and window sills
- Discarded wings near windows, doors, or light fixtures (swarming season: spring/early summer)
- Frass (droppings) — tiny wood-colored pellets below drywood termite galleries
- Bubbling or peeling paint that looks like water damage but isn’t
- Doors and windows sticking — termite damage warps frames
If you see any of these, call for an inspection immediately. Don’t wait. Termite colonies eat 24/7 and a mature colony can consume several pounds of wood per year.
Prevention: Keeping Termites Out
Treatment is reactive. Prevention is cheaper. Here’s what every homeowner should do:
- Keep wood away from soil: Maintain 6+ inches between soil and any wood siding, framing, or trim. This includes mulch — keep it 12+ inches from the foundation.
- Fix moisture problems: Termites need water. Repair leaky faucets, AC drip lines, and poor drainage. Ensure gutters discharge away from the foundation.
- Remove wood debris: Old stumps, firewood stacked against the house, construction lumber left in the crawl space — all termite magnets.
- Ventilate crawl spaces: Proper ventilation reduces moisture that attracts subterranean termites.
- Pre-treat during construction: If building new or adding on, borate-treated lumber and soil pre-treatment cost $1,000 to $2,500 and provide long-term protection.
Regular home maintenance that addresses moisture and wood-to-soil contact is the best ongoing termite prevention. It costs nothing extra if you’re already maintaining your property.
Termite Treatment Cost by Home Size
To give you a clearer picture, here’s what full liquid barrier treatment typically costs based on square footage:
| Home Size | Liquid Barrier | Bait System (Year 1) | Tent Fumigation |
|---|---|---|---|
| 1,000 sq ft | $500–$1,200 | $1,500–$2,500 | $1,200–$1,800 |
| 1,500 sq ft | $700–$1,800 | $1,800–$2,800 | $1,500–$2,200 |
| 2,000 sq ft | $900–$2,200 | $2,000–$3,200 | $2,000–$2,800 |
| 2,500 sq ft | $1,100–$2,500 | $2,200–$3,500 | $2,200–$3,200 |
| 3,000+ sq ft | $1,500–$3,000+ | $2,500–$4,000 | $2,500–$3,500+ |
Foundation type also plays a role. Slab foundations require drilling through concrete to inject termiticide underneath — that adds $200 to $500 to the liquid barrier price. Pier-and-beam and crawl space foundations are easier to access but often have more exposed wood that needs treatment.

Termite Bonds and Warranties
A termite bond is an annual service contract between you and the pest control company. After the initial treatment, you pay $200 to $400 per year for ongoing protection. Here’s what a typical bond includes:
- Annual inspection: A technician inspects the property each year for signs of termite activity
- Re-treatment guarantee: If termites are found, the company re-treats at no additional cost
- Damage repair (some bonds): Premium bonds include structural repair coverage — the company pays for termite damage found during the bond period
Bonds are especially valuable in high-risk areas and during real estate transactions. Lenders in the Southeast and Gulf Coast often look favorably on homes with active termite bonds. If you’re financing a home with a HELOC or mortgage, an active termite bond protects your investment and can simplify future resale.
How to Choose a Termite Treatment Company
Not all pest control operators are equal when it comes to termites. Here’s what to look for:
- Licensed and insured — Verify their pesticide applicator license with your state’s Department of Agriculture
- Written warranty/guarantee — Most reputable companies offer 1-year minimum, often 5-year, with annual renewal options
- Multiple treatment options — A company that only offers one method may not give you the best solution for your situation
- At least three quotes — Termite treatment pricing varies 30–50% between companies for the same scope of work
- Damage repair guarantee — Some companies guarantee structural repair if termites return under warranty

Frequently Asked Questions
How much does a termite inspection cost?
Many pest control companies offer free inspections, hoping to win the treatment contract. Independent inspections run $75 to $150. During a home sale, the WDI (Wood Destroying Insect) report costs $75 to $125 and is often required by the lender.
Does homeowner’s insurance cover termite damage?
No. Standard homeowner’s insurance policies exclude termite damage because it’s considered a maintenance issue, not a sudden event. Some companies offer add-on termite bonds or warranties that function like insurance, typically $200 to $400 per year.
How long does termite treatment take?
Liquid barrier treatment takes 4 to 8 hours for an average home. Bait station installation takes 2 to 4 hours. Tent fumigation requires 2 to 3 days from setup through aeration. You can stay home during liquid and bait treatments but must vacate during fumigation.
Which termite treatment lasts the longest?
Liquid barriers with Termidor or similar products last 5 to 10 years. Bait systems require ongoing annual monitoring and renewal. Fumigation provides no residual protection — it kills what’s there but doesn’t prevent re-infestation. Borate wood treatment lasts the lifetime of the treated wood.
Can I treat termites myself?
DIY spot treatments (foam products, borate sprays) can address small, accessible infestations. But for whole-house treatment, professional equipment and commercial-grade products are necessary. Liquid barrier treatment requires specialized injection equipment and knowledge of the foundation layout. Fumigation is strictly professional-only.
Are termites more common in certain states?
Yes. Subterranean termites are most active in the Southeast, Gulf Coast, and southern Midwest. Drywood termites dominate in coastal California, South Florida, and Hawaii. Northern states above the termite line (roughly the 40th parallel) see fewer infestations but aren’t immune. Check your state’s page for regional specifics.
Bottom Line
Termite treatment costs $500 to $3,500 depending on the method, home size, and infestation severity. The real expense comes from delaying treatment — every year you wait adds to potential structural damage that costs far more to fix than the treatment itself. Get an inspection, get quotes from multiple companies, and deal with it promptly. Your house is too big an investment to share with insects that eat it from the inside out.
