Bed bug heat treatment costs about $1–$3 per sq. ft., so most homeowners pay $1,500–$4,500 to heat-treat a 1,500 sq. ft. home and $1,000–$3,000 for a 1,000 sq. ft. apartment (Angi, HomeAdvisor and HomeGuide data, as of October 2026).
Updated October 8, 2026. Source: Angi + 3 more. National US estimates.
Heat treatment raises the temperature of a room or whole home to roughly 120–145°F and holds it there for hours, killing bed bugs and their eggs without a long course of insecticide visits. It's popular with families, pet owners and anyone who wants the problem solved in a single day.
This guide covers what heat treatment costs by home size, how it compares with other methods, a typical line-item budget and how to get comparable quotes. For an overview of every method, see our main bed bug treatment cost guide.
Average cost
Typical heat treatment prices at $1–$3 per sq. ft., as of October 2026:

| Small apartment or a few rooms (about 1,000 sq. ft.) | $1,000–$3,000 | One-day treatment; less furniture to move |
| Average home (about 1,500–2,000 sq. ft.) | $1,500–$6,000 | Most common whole-home job |
| Large home (3,000–4,000 sq. ft.) | $3,000–$12,000 | More equipment and longer heating time |
Whole-home heat treatment cost by size

| 1,500 sq. ft. | $1,500–$4,500 |

Heat vs. other bed bug treatments
| Method | Cost per sq. ft. | Visits |
|---|---|---|
| Heat | $1–$3 | Usually one, plus a follow-up check |
| Heat plus residual insecticide | $2–$4 | One treatment day, longer protection |
| Chemical | $2–$5 | Typically 2–3 visits |
| Steam | $2–$7.50 | Often repeated |
| Fumigation | $4–$8 | One, but the home must be vacated longer |
Cost breakdown: materials, labor, permits and extras
Line-item estimate for a whole-home heat treatment of a 1,500 sq. ft. house with one follow-up inspection. Ranges are national, as of October 8, 2026.
| Cost item | Typical range | What it covers |
|---|---|---|
| Heat treatment (equipment, crew and labor) | $1,500–$4,500 | Heaters, fans, temperature sensors and a full treatment day |
| Initial inspection | $65–$200 | Visual inspection; often credited toward treatment |
| Follow-up inspection | $75–$225 | About 4–6 weeks after treatment |
| Permits | $0–$0 | Not required for residential heat treatment |
| Contingency | $0–$750 | Residual insecticide in wall voids or extra furniture treatment |
| Estimated total | $1,650–$5,700 | Before any discounts or rebates |
Square footage drives almost the entire cost; inspection and follow-up add only a few hundred dollars.
What affects the price
- Home size. Heat treatment is priced by area at $1–$3 per sq. ft., so a 1,000 sq. ft. apartment costs about $1,000–$3,000 and a 2,000 sq. ft. home about $2,000–$6,000.
- Equipment. Companies use propane or electric heaters, fans and remote temperature sensors; homes that need more heaters or long heating times cost more, and adding a residual insecticide raises the price to about $2–$4 per sq. ft.
- Preparation. Heat-sensitive items (medications, candles, aerosol cans, some electronics) must be removed, and clutter lengthens heating time. Good prep keeps the job to a single day and avoids extra charges.
- Guarantee. Many companies include a 30-day guarantee at no extra cost, and some offer longer or multi-year guarantees at a higher price. Read what triggers a free re-treatment.
- Follow-up. A follow-up inspection 4–6 weeks after treatment typically costs $75–$225 when it isn't bundled into the quote.
Ways to save
- Get at least three written quotes priced per square foot and compare what each includes: number of rooms heated, follow-up visit and guarantee length.
- Treat only the affected rooms if an inspection confirms the bugs haven't spread; room-by-room heat jobs cost far less than whole-home treatment.
- Do all preparation yourself, following the company's checklist, so the crew doesn't bill extra time for moving clutter.
- Ask whether the $65–$200 inspection fee is credited toward the treatment.
- Book promptly: a small infestation treated early costs less than one that has spread through the home.
How to get an accurate quote
Ask at least three licensed pest control companies that own professional heat equipment for an inspection and written quote. Provide the same details to each:
- The square footage to be treated and the number of rooms, including where you've found bugs or bites.
- The type of home (house, condo, apartment) and whether neighboring units share walls.
- Anything that can't be heated, such as musical instruments, art, medications or electronics.
- Ask what's included: whether a residual insecticide is used, the follow-up visit, the guarantee period and how long you must stay out of the home.
FAQ
Does heat treatment kill bed bugs in one treatment?
Usually yes. Holding the space at lethal temperatures kills adults, nymphs and eggs, but heat leaves no residual protection, so many companies add a follow-up inspection or a residual product.
How long does a bed bug heat treatment take?
The heating phase typically lasts 2–3 hours at 120–140°F, and the whole visit takes about 6–9 hours. You can usually return the same day once the home cools.
Is heat treatment cheaper than chemical treatment?
Per square foot it often is: heat runs $1–$3 versus $2–$5 for chemical treatment, and heat usually needs fewer visits.
