Termite Treatment Cost 2026: What You'll Pay for Inspection, Treatment & Prevention
Termites cause over $5 billion in property damage across the U.S. every year — and homeowner's insurance doesn't cover it. That's not a typo. If termites eat through your floor joists or wall studs, it's 100% on you. The good news is that treatment and prevention are relatively affordable compared to the alternative. Let's break down exactly what you'll pay in 2026.
Termite Inspection Cost
A professional termite inspection typically costs $75–$150, but here's a pro tip: many pest control companies offer free inspections as a way to get in the door. Terminix, Orkin, and most regional companies will inspect your home at no cost. If you're buying a home, the seller usually pays for a Wood Destroying Insect (WDI) report, which costs $50–$150 depending on your state. In many Southern states, a WDI report is required by the lender.
What Inspectors Look For
- Mud tubes — pencil-width tunnels along foundation walls (subterranean termites)
- Frass — sawdust-like droppings near wood (drywood termites)
- Hollow-sounding wood — tap on baseboards, door frames, and window sills
- Discarded wings — near windows, doors, or light fixtures (swarmer termites)
- Visible damage — bubbling paint, sagging floors, crumbling wood
Termite Treatment Cost by Method
| Treatment Method | Cost Range | Best For |
|---|---|---|
| Liquid barrier treatment | $3–$6 per linear foot | Subterranean termites, prevention |
| Bait station system | $8–$12 per station | Ongoing monitoring, eco-friendly option |
| Fumigation (tenting) | $1,200–$2,500 for 1,250 sq ft | Drywood termites, severe infestations |
| Heat treatment | $800–$2,500 | Localized drywood infestations, chemical-free |
| Spot treatment (foam/liquid) | $200–$900 | Small, localized infestations |
| Borate wood treatment | $1–$3 per sq ft | New construction prevention |
Liquid Barrier Treatment
The most common approach for subterranean termites. A pest control professional trenches around your home's foundation and applies a termiticide (Termidor is the industry standard). For a typical home with 150 linear feet of foundation, expect to pay $450–$900. The treatment lasts 5–10 years and creates a continuous chemical barrier that kills termites on contact.
Bait Station System
Bait stations (like the Sentricon system) are installed every 10–15 feet around your home's perimeter. Termites find the bait, carry it back to the colony, and it wipes out the entire colony over weeks. Installation runs $1,500–$3,000 for an average home, with annual monitoring at $200–$400/year. More expensive upfront but excellent for ongoing protection.
Fumigation (Tenting)
If you have drywood termites — common in Florida, Southern California, and Hawaii — fumigation may be your only option for a whole-home infestation. The entire house gets covered in a tent, and a gas (vikane/sulfuryl fluoride) penetrates every piece of wood. For a 1,250 sq ft home, expect $1,200–$2,500. Larger homes can run $2,500–$5,000+. You'll need to vacate for 2–3 days, remove all food and medications, and make arrangements for pets.
Heat Treatment
A chemical-free alternative that works by raising the temperature inside infested areas to 120–140°F, which kills termites at all life stages. Costs $800–$2,500 depending on the treatment area. Great for localized infestations where you want to avoid chemicals, but not as effective for whole-home problems.
Termite Damage Repair Costs
Here's where things get scary. The average termite damage repair costs $1,000–$9,000, but severe structural damage can exceed $30,000. Common repairs include:
- Subfloor replacement — $1,000–$5,000
- Wall framing repair — $1,500–$10,000
- Door/window frame replacement — $200–$600 per frame
- Floor joist sistering or replacement — $2,000–$8,000
- Cosmetic repairs (drywall, paint) — $500–$2,000
Annual Termite Bond: Worth It?
A termite bond costs $200–$400 per year and typically includes annual inspections, re-treatment if termites return, and sometimes damage repair coverage. In high-risk states, this is a no-brainer. Think of it as termite insurance — $200–$400/year to protect against thousands in potential damage.
Highest Risk States
The following states have the heaviest termite pressure due to warm, humid climates:
- Florida — both subterranean and drywood species; year-round risk
- Texas — Formosan subterranean termites especially in Gulf Coast areas
- Louisiana — extremely heavy Formosan termite populations in New Orleans
- Georgia — significant subterranean termite pressure statewide
- South Carolina — high risk, especially in coastal areas
- Alabama & Mississippi — warm, moist conditions ideal for termites
- California — drywood termites in Southern California, subterranean in Central Valley
DIY vs. Professional Treatment
You can buy DIY termite treatments at hardware stores for $50–$200, but honestly? This is one job where professional treatment pays for itself. Professionals have access to commercial-grade products (like Termidor), specialized equipment, and the expertise to identify the species and extent of infestation. A missed colony or incomplete barrier means termites come right back. Plus, most DIY treatments don't come with a warranty — professional treatments include a 1–5 year guarantee.
The smart move: get a free inspection from 2–3 companies, compare quotes, and invest in professional treatment plus an annual bond. It's a small price to pay to protect what's probably your biggest asset.
