Termite Treatment Cost Calculator & Price Guide

Termites eat wood from the inside, and damage can build for a long time before it shows. Treatment kills the colony or blocks termites from reaching your home. The price depends on the method, the size of the house, and how far the infestation has spread.

Figures below come from published guides and carry a check date of Oct 11, 2026. Treatment is only part of the cost story, since repairing damage and keeping a protection plan add to the total.

Spot treatment targets a small, contained area. It costs less but only suits a limited problem. Liquid pesticide treatments, bait systems, heat, and fumigation cover larger areas or whole structures and cost more. Fumigation, which seals the home under a tent and fills it with gas, sits at the top of the range.

Each method fits different situations. Drywood termites, which live inside the wood itself, are often handled with fumigation or heat. Subterranean termites, which nest in the ground, are commonly treated with liquid barriers in the soil or bait stations. A licensed pest control company can identify the species and recommend a method.

Treatments around the foundation are often priced by the linear foot of the home's perimeter.

Measure the distance around your foundation and multiply by the rate to get a rough estimate. Ask the company to confirm that the quote covers the full perimeter and any slab penetrations.

You can build a working estimate in a few steps. Pick the method your inspector recommends, then multiply your home's perimeter by the per-foot rate for perimeter treatments, or use the method range in the table. Add the cost of an inspection if one is not included, and any warranty or bond. Treat the result as a range to compare with written quotes, because a company that inspects your house can price it more accurately than any calculator.

Some national pest control companies publish their own ranges. These tend to differ from independent guides because they reflect the company's own methods and service plans.

Treatment often comes with a bond, an ongoing protection plan with periodic inspections. A bond typically includes retreatment if termites return, though terms differ, so read what is covered. Damage repair is a separate expense. Replacing damaged wood or structural members may cost more than the treatment itself.

Common signs include mud tubes along the foundation, discarded wings near windows and doors, hollow-sounding wood, and sawdust-like droppings called frass near small holes in wood. Seeing swarming insects indoors is a reason to call a licensed inspector promptly. Because termites work out of sight, a professional inspection is the reliable way to confirm an infestation and its extent before you commit to a treatment.

• Home size. A larger footprint means more material and time.
• Infestation size. A localized problem costs less than one spread across the house.
• Termite species. Subterranean and drywood termites are treated differently.
• Treatment method. Fumigation and heat cost more than spot or bait treatment.
• Foundation type. Slab, crawl space, and basement foundations each affect access and drilling.
• Local rates. Pricing varies by region and by company.
• Follow-up. Return visits and bond renewals add to the long-term cost.

Termite pricing is hard to pin down because no two infestations are the same.

One company may quote a single treatment, while another bundles inspections, warranties, and retreatment. The ranges are wide because they cover everything from a small spot job to a whole-home treatment.

Termite treatment involves pesticides, and in many states only a licensed applicator may apply termiticides for hire. Over-the-counter products can handle a small, surface-level problem, but they rarely reach a colony hidden in walls or soil. Misusing pesticides can harm people, pets, and groundwater. For anything beyond a minor issue, hire a licensed pest control professional, and ask which products they plan to use and what precautions you should take, such as staying out of the home during fumigation. Your state's department of agriculture or pest control board can confirm that a company is licensed.

• What species do you think I have, and what method do you recommend?
• Does the price include the inspection, retreatment, and a written warranty?
• Which products will you use, and what safety steps do I need to follow?
• What does the bond cover, and what does it cost to renew?
