Termite Control Cost: Average Prices & Cost Factors

Termite control covers killing an active colony and, in many cases, protecting the house against the next one. The method matters as much as the house. A spot treatment on one section of wall is a small job, while a whole-structure fumigation or a baiting program around the full perimeter is a much larger one.

The prices below come from published guides and company pages, and they were checked on Oct 13, 2026. One company's price list is not a national average, so each row names its source. If you suspect termites, a licensed pest control company can inspect the property and give a written quote.

This Old House lists a spot treatment at $350 – $1,000, a pesticide spray at $150 – $1,500, heat treatment at $1,300 – $2,500, bait systems at $400 – $3,000, and fumigation at $1,500 – $5,000. A liquid barrier and bait are the two usual routes for subterranean termites, which nest in the soil. Fumigation and heat treat the whole structure and are more common with drywood termites that live inside the wood.

The table also shows figures from two other sources. Orkin, a pest control company, lists baiting at $1,000 – $2,300 and liquid perimeter treatment at $1,700 – $2,700 on its own price page. HomeLight reports whole-home fumigation at $1,200 – $2,500. Company price pages reflect that company's own services and may not match what other providers charge in your area.

Sources disagree because the jobs differ. A spot treatment and a full-structure fumigation sit at opposite ends of the same search term.

This Old House reports $700 – $2,000 for typical termite treatment. Orkin describes a much wider span, $250 – $5,000, from a spot treatment to a whole-home solution, and its upper figure is "or more." The first figure describes a typical job and the second spans the full range of methods. Read the label before comparing numbers.

Different termites live and feed in different places, so the treatment changes.

This Old House lists drywood termites at $225 – $900, Formosan termites at $250 – $1,500, subterranean termites at $225 – $900, and dampwood termites at $250 – $2,500. Formosan colonies can be large and aggressive, and dampwood termites need damp wood, so the treatment plan may include fixing the moisture source as well. A pest control company can identify the species before quoting a method.

Perimeter treatments are often priced by the linear foot around the house. Inspections and damage repair are separate line items.

This Old House reports treatment priced at $5 – $20/linear ft, which scales with the length of the foundation. A termite inspection runs $75 – $325, and some companies offer a free inspection. Repair of damaged wood is a separate cost. This Old House notes that many homeowners spend around $2,000 on repairs, though the real figure depends on how much wood was damaged.

• Termite species. Subterranean, drywood, dampwood, and Formosan termites call for different treatments.
• Extent of the infestation. A small, early colony costs less to treat than a widespread one.
• Treatment method. Spot treatments, liquid barriers, baits, heat, and fumigation are priced differently.
• Home size and perimeter. Larger homes and longer foundations cost more to treat.
• Access. Slabs, patios, and landscaping may need drilling or digging for treatment.
• Warranty and monitoring. Some companies sell a service plan or bond that adds to the price.
• Local pricing. Rates vary by region and company.
• Follow-up visits. Severe infestations may need more than one treatment.

Liquid barrier. A treated zone in the soil around the foundation stops subterranean termites from reaching the house. It is applied by a licensed pest control professional, often with trenching or drilling.

Bait. Stations around the property draw termites in so they carry the active ingredient back to the colony. Baiting works slowly and needs periodic checks.

Heat. The structure or room is heated to a temperature that kills termites in the wood. It targets localized areas.

Fumigation. The whole house is tented and treated with gas, and occupants and pets must leave. It is used for large drywood infestations. The pest control company will give you preparation and re-entry instructions.

Product choices and application are regulated, and chemical applications require licensed applicators in most states. Talk to a licensed company about which method fits your termite species and house.

1. Get an inspection from a licensed pest control company, or get inspections from two or three.
2. Ask for the termite species identification and a written scope of work.
3. Compare methods and what each includes: inspection, treatment, retreatment, and warranty.
4. Ask whether damage repair is included. Usually it is not.
5. Check licensing and insurance with your state's regulating agency.
6. Be cautious about any company that pushes you to sign the same day.
