How Much Does Termite Treatment Cost?
$500 to $3,000 is the typical cost for termite treatment in most homes, with the national average around $1,500. The type of treatment is the biggest cost factor: liquid barrier treatments cost $500-$2,000, bait station systems cost $1,200-$3,500 for installation, and whole-house fumigation costs $2,000-$8,000. Ongoing annual monitoring and warranties add $200-$500 per year.
Knowing how much termite treatment costs is crucial because termites cause an estimated $5 billion in property damage across the United States each year, and the average homeowner spends $3,000-$15,000 repairing termite damage. Early detection and treatment is critical because by the time visible damage appears, a colony has typically been active for 3 to 5 years. Termite damage often goes hand-in-hand with moisture problems, so also check our mold remediation cost guide if you notice signs of water intrusion.
Termite Treatment Cost by Method
Liquid chemical barriers cost $500 to $2,000 and are the most common treatment for subterranean termites. The table below breaks down the five main treatment methods, their cost ranges, and what each involves.
| Treatment Method | Cost Range | Description |
|---|---|---|
| Liquid chemical barrier (Termidor, Premise) | $500 - $2,000 | Most common. Trench treatment around foundation. Lasts 5-10 years. |
| Bait station system (Sentricon, Trelona) | $1,200 - $3,500 install + $300 - $500/yr | In-ground stations with bait. Requires ongoing professional monitoring. |
| Spot treatment | $200 - $800 | Treats a specific localized area. Uses liquid termiticide, foam, or borate. |
| Whole-house fumigation (tenting) | $2,000 - $8,000 | Home sealed and filled with gas. Kills all termites. Requires 2-3 day vacancy. |
| Heat treatment | $1,500 - $4,000 | Chemical-free. Heats areas to 120-140F. Works for drywood termites only. |
Factors That Affect Termite Treatment Cost
$500 to $3,000 is the typical range, and several key factors determine where your project falls within it.
Home Size (Linear Footage)
Liquid barrier treatments typically run $4 to $16 per linear foot of foundation. The cost of termite treatment scales with your home's perimeter. A home with 150 linear feet costs significantly less than one with 250 linear feet. The perimeter measurement drives the price because the trench must be dug along the entire foundation edge. Multi-story homes cost the same as single-story homes with the same footprint since treatment targets the ground-level foundation.
Infestation Severity
A minor infestation caught early costs $200 to $800 for spot treatment. A moderate infestation with activity in multiple areas typically needs a full liquid barrier treatment at $500 to $2,000. Severe infestations with widespread structural damage may require fumigation ($2,000 to $8,000) plus structural repairs that can add $3,000 to $15,000 or more.
Termite Species
Subterranean termites are the most common and are typically treated with liquid barriers or bait stations at $500 to $3,500. Drywood termites live inside wood with no soil contact and often require fumigation ($2,000 to $8,000) or localized heat treatment ($1,500 to $4,000). Formosan termites, an aggressive subterranean subspecies found primarily in the Southeast, form colonies of several million workers and may need more aggressive treatment.
Construction Type
Slab foundations cost $500 to $1,500 to treat because the barrier only needs to be applied around the exterior. Homes with crawl spaces cost $800 to $2,200 since both interior and exterior treatment is required. Homes with basements may need treatment along interior foundation walls as well, adding $200 to $500. If your foundation has cracks or damage, review our foundation repair cost guide since structural issues can create new entry points for termites.
Geographic Location
Treatment costs run 10% to 30% higher in heavy termite pressure zones like the Southeast, Gulf Coast, and parts of California. How much it costs to treat termites runs higher in Florida, Texas, Louisiana, and Georgia, where year-round termite activity is driven by warm, humid climates.
Structural Damage Repair
Repairing termite damage costs $3,000 to $15,000 on average, separate from treatment. Replacing a baseboard or door frame costs $200 to $500, damaged floor joists run $1,000 to $5,000, and severe structural damage to load-bearing walls can reach $10,000 to $30,000. Homeowners insurance does not cover termite damage.
Annual Termite Protection Costs
Annual termite warranties and monitoring plans cost $200 to $500 per year. Most pest control companies offer renewable plans that cover retreatment if termites return. These plans are worthwhile because a single retreatment without a warranty costs as much as the original treatment.
| Annual Plan | Cost per Year | Coverage |
|---|---|---|
| Retreatment warranty | $200 - $350 | Free retreatment if termites return. |
| Retreatment + damage repair (termite bond) | $300 - $500 | Retreatment plus repair of new damage, typically up to $100,000-$250,000. |
| Bait station monitoring | $300 - $500 | Quarterly inspection and maintenance of bait stations. |
A termite bond is the most thorough option, functioning like an insurance policy where the pest control company covers both retreatment and repair of any new damage. Most bonds require an annual inspection to stay active and are transferable to a new owner if you sell your home.
How to Save Money on Termite Treatment
$50 to $900 in potential savings is achievable with the right approach. These tips can help reduce your total cost.
- Get multiple quotes. Termite treatment pricing varies widely between companies. Get at least 3 written estimates that specify the treatment method, warranty terms, and any additional costs. Pricing differences of $500 or more for the same treatment are common.
- Catch it early. Annual termite inspections ($75 to $150, often free from pest companies) catch infestations before they cause expensive damage. A $1,000 treatment is far cheaper than $10,000+ in structural repairs. A home inspection ($300 to $500) can also identify termite risk factors.
- Choose liquid treatment when possible. Liquid barriers are the most cost-effective option for subterranean termites, providing 5 to 10 years of protection at a lower cost than bait systems.
- Ask about financing. Many pest control companies offer payment plans for larger treatments like fumigation.
- Negotiate the annual warranty. If you are paying for initial treatment, ask for a free first year of warranty coverage. Many companies will include it at no extra charge.
- Reduce termite risk with prevention. Keep mulch at least 12 inches from the foundation, fix leaky faucets and gutters, ensure proper drainage away from the house, and remove dead trees or stumps from the yard.
- Bundle with other services. Some pest control companies offer discounts if you combine termite treatment with general pest control, saving $100 to $200 per year.

How much does termite treatment cost?
Termite treatment costs $500 to $3,000 for most homes, with the national average around $1,500. Liquid chemical barrier treatment runs $500 to $2,000, bait station systems cost $1,200 to $3,500 for installation plus $300 to $500 per year for monitoring, and whole-house fumigation costs $2,000 to $8,000.
Does homeowners insurance cover termite damage?
No, standard homeowners insurance does not cover termite damage or treatment costs. Insurance companies classify it as a preventable maintenance issue. The average homeowner pays $3,000 to $15,000 out of pocket for termite damage repairs, which is why annual inspections and termite bonds ($200 to $500 per year) are worthwhile investments.
How long does termite treatment last?
Liquid barrier treatments using Termidor (fipronil) typically last 8 to 10 years, while older products may last only 5 years. Bait station systems require ongoing quarterly monitoring to remain effective. Fumigation kills all existing termites but provides no residual protection, so re-infestation is possible without follow-up prevention. Most pest control companies offer annual warranties for $200 to $400 per year.
What are signs of termite infestation?
The most common sign is mud tubes on foundation walls, which are pencil-width tunnels that subterranean termites build to travel between soil and wood. Other signs include hollow-sounding wood when tapped, discarded wings near windows or doors in spring, small piles of frass (droppings that look like tiny pellets), bubbling paint, and sagging wood. By the time these signs appear, the colony has usually been active for 3 to 5 years.
