Buying a bed bug heater is one of the most important equipment decisions a pest control company, hotel, property manager, or facilities team will make — and the wrong choice is expensive twice: once when you pay for it, and again when it fails mid-treatment. Before you spend a dollar, it pays to understand exactly what separates professional-grade equipment from the underpowered “people heaters” sold as bed bug solutions.
This guide walks through the critical factors that matter when you are buying a bed bug heater, the heater types on the market, when treatments fail, then answers the most common questions buyers ask before they commit. Every PestPro unit is designed and hand-built in Fort Collins, Colorado, and engineered for commercial, repeatable use.
What to Know Before Buying a Bed Bug Heater
Heat works because it is physics, not chemistry. All life stages of bed bugs — adults, nymphs, and eggs — die at lethal temperatures, and unlike chemicals, they cannot evolve resistance to heat. The catch is that reaching and holding those temperatures across an entire room takes real power and durable components. That is the whole reason buying a bed bug heater built for the job matters so much.
For lodging operators specifically, PestPro recommends the 208V 10kW or 240V 10kW whole-room heater as the right starting point for guest rooms and suites.
Bed Bug Heater Types Compared
Before the seven buying factors below, start with category. The right question isn’t “which bed bug heater is best?” It’s “which system category matches my use case, space, and power supply?”
| Heater Type | Best For | Not For |
|---|---|---|
| Portable item chamber | Luggage, clothing, small items after travel | Whole-room infestations |
| Electric whole-room (10kW) | Single rooms: hotel rooms, apartments, shelters | Multi-story buildings without sufficient circuits |
| Propane whole-room | Large structures, locations with limited electrical | Small rooms or areas requiring discretion |
| Truck-mounted system | Multi-unit buildings, high-volume PCO operations | Single homeowners or occasional use |
If you’re treating a suitcase after a trip, you need a chamber. If you’re treating a 400 sq ft hotel room on a recurring basis, you need an electric whole-room unit. If you’re a pest control company treating apartment buildings daily, you need a truck-mounted system — see the Bed Bug Beast package.
7 Critical Factors When Buying a Bed Bug Heater
Use these seven factors as your checklist when buying a bed bug heater for commercial or repeated use.
1. Power and coverage
Heat output is the first thing to check. As a rule of thumb, every 1,000 watts of output treats roughly 30–40 square feet of properly prepped space. PestPro heaters deliver 10,000 watts (34,120 BTUs), enough to bring 300–400 square feet up to lethal temperature when the room is sealed and pre-heated. Match the heater’s coverage to your largest typical room before buying.
2. All-steel build quality
The single biggest difference between professional equipment and consumer gear is what the heater is made of. Plastic housings warp, crack, and fail at the very temperatures bed bug work demands. PestPro components are rated to withstand 170–180° F. If you are buying a bed bug heater for daily commercial use, all-steel construction is non-negotiable — see our breakdown of all-steel versus plastic bed bug heaters.
3. A separate heater and external fan
Avoid all-in-one units with a built-in fan. If heat is not actively pushed into voids, cracks, and furniture, bed bugs simply move away from the hot spot and survive. A high-volume, heat-resistant external air mover lets you direct hot air exactly where the bugs hide. Pairing a whole-room heater with a dedicated fan is the method that actually works — learn how bed bug heat treatment works and why it wins.
4. Proven temperature performance
The equipment must reliably reach and hold a lethal temperature. Bed bugs and their eggs die at 120° F; PestPro heaters are factory-set to 135° F so heat penetrates furniture and baseboards, not just the open air. Confirm the unit’s maximum sustained temperature before buying — this is exactly what kills bed bugs instantly and permanently.
5. Warranty and lifespan
Commercial buyers should treat a heater as a multi-year asset. Quality components allow PestPro equipment to last up to 10 years with daily use. Because adult bed bugs can survive up to a year without feeding, the ability to re-treat the same property over time is essential — another reason buying a bed bug heater you own beats one-off chemical visits.
6. Return on investment versus paid treatments
Professional heat treatment typically runs $2.00–$6.50 per square foot with a $1,000 minimum per job. Owning your equipment lets you treat unlimited rooms and recover the cost quickly — the core reason pest control companies and property managers move from renting to buying a bed bug heater outright. If you are weighing buying versus a single professional visit, read our DIY vs. professional cost comparison.
7. U.S. manufacturing and real support
When equipment fails, response time matters. PestPro heaters are hand-built in the USA and backed by direct phone and text support. Buyers who need to compare models or confirm voltage can start at where to purchase a bed bug heater, and large operators can scale up with the Bed Bug Beast 6–8 heater package.

When Bed Bug Heat Treatment Fails — Real Limitations to Plan For
Most bed bug heater marketing pages skip this section entirely. We won’t. A certain percentage of heat treatments — perhaps 10 to 20 percent — fail to kill all the bed bugs present, most often due to inadequate room prep. The five most common causes:
- Insufficient duration — cutting the treatment short before all harborages reach 122°F.
- Poor room prep — clutter creates insulated pockets and shields dense items like stacked books from lethal heat.
- Structural heat sinks — drop ceilings, uninsulated wall voids, and trailer floor cavities may never reach lethal temperature.
- Inadequate monitoring — a single air-temperature reading misses cold spots at floor-wall junctions and inside furniture.
- No active adjustments — setting the heater and walking away instead of repositioning fans and/or heaters to reach every zone.
Heat treatments also provide no residual protection — bed bugs can re-enter a treated space from adjacent units, new furniture, or visitors within hours of cool-down. Prevention and early detection remain the best defense against reintroduction, especially in multi-unit buildings.
Where can I buy a heater to kill bed bugs?
You can buy do-it-yourself (DIY) bed bug heat treatment equipment directly from us at PestPro Thermal Systems. Call or text us at 970-443-8119 for meaningful answers to your questions.
One word of caution: if you buy a single heater with a built-in fan, the heat may not dissipate quickly or effectively enough to reach hard-to-reach places. Bed bugs will sense where the heat is coming from and move away from it — which can make the problem worse. That is why an external, high-temperature air mover is part of every serious setup.
What kind of heater kills bed bugs?
Commercial bed bug heat machines are engineered to quickly raise a room to lethal temperatures of at least 125° F. PestPro heaters are set to achieve 135° F and can be adjusted for different conditions. All PestPro components are manufactured to withstand 170–180° F.
This durability is why the Government of the Northwest Territories in Canada purchased large volumes of PestPro Thermal Systems equipment to remediate bed bugs territory-wide.
By contrast, ordinary “people heaters” used to warm living spaces typically max out around 90° F — well below the temperature required to kill bed bugs. Disabling the thermostat on those units will void the warranty, burn out the internal components, and can even start a fire if the insulation melts. Don’t do it.
Do bed bug heaters really work?
Yes — bed bug heaters really work. Commercial heat equipment from PestPro uses only high-quality, durable components and can last up to 10 years with daily usage. All bed bugs die, regardless of strain, at around 120° F within 15 minutes.
Anyone with a powerful enough heater and a high-volume, heat-resistant fan can kill bed bugs without throwing out furniture. A successful heat treatment happens in a single day, while chemical insecticide treatments stretch over weeks and expose people and pets to residual chemicals.
As long as you bring the entire room up to a lethal temperature quickly and have pre-sealed it with plastic sheeting and painter’s tape so heat and bugs cannot escape through cracks, vents, and conduits, 99% of users have first-time success. Owning your own equipment lets you repeat the process whenever it is needed.
Can a regular heater kill bed bugs?
No. A regular heater will not kill bed bugs, eggs, or nymphs. As explained above, heaters designed to keep humans warm cannot reach or sustain lethal temperatures, so they are inadequate for the job.
Can I get rid of bed bugs myself?
Yes. For the vast majority of light-to-moderate infestations, a DIY heat treatment succeeds on the first attempt when you follow the manufacturer’s instructions and replicate the methods professionals use. Unlike a paid exterminator visit, owning the equipment means you can run unlimited follow-up treatments at no extra cost if the first one doesn’t fully resolve the problem.
Is it possible to have just one bed bug?
Yes, technically — bed bugs can hitch a ride on a single shoe, backpack, or piece of luggage. But if you’ve spotted one, chances are more are hiding nearby. A whole-room electric heat treatment is the most reliable way to confirm the infestation is fully eliminated rather than just the one bug you happened to see.
Should I throw away furniture with bed bugs in it?
No. Heat treatment lets you keep your mattress, couch, and other furniture. Sustained heat above 120°F kills all life stages, including eggs, inside upholstery and cushions — there’s no need to replace items just because bed bugs were found in them.
How do you keep bed bugs from spreading to other rooms during treatment?
Seal the room the same way you would before painting it: plastic sheeting and painter’s tape across doors, vents, and windows, with all cracks and baseboard gaps caulked shut. Remove switch and outlet plates so heat can penetrate the wall cavities where bed bugs often hide near warm wiring. Every PestPro heater package includes a pre-treatment prep checklist covering this step by step.
What do bed bugs look like?
Bed bugs are reddish-brown and about the size of an apple seed when fully grown. They are flat before feeding on blood and rounded and engorged afterward.
How long do you need to heat a room to kill bed bugs?
To answer this meaningfully, you need to know the room’s dimensions, what is inside it, how well it is insulated, and whether it contains heat sinks — items that absorb heat like a sponge, such as mirrors, exposed masonry, or concrete walls and floors. Details matter.
The following conditions should be met first:
- Standard North American 8-foot ceilings
- Wood-frame construction (wallboard on wooden studs)
- Carpeted floors with insulation underneath
- An average amount of furniture and personal items (not hoarder-level stacks)
- All cracks and vents sealed, and windows covered from the inside with thin plastic and painter’s tape so no air or bed bugs can move in or out
- Light-switch and outlet plates removed so heat can reach inside the walls, where bed bugs gather near warm electrical current
- The room pre-heated for at least 2 hours to 85° F or higher before treatment begins
Once those conditions are met, expect 1,000 watts of output to treat 30–40 square feet. Ten 1,000-watt hair dryers running together would create 10,000 watts of heat — a useful way to picture the scale.
Extrapolating to a 10,000-watt electric bed bug heater, you get roughly 300–400 square feet of coverage. PestPro equipment delivers 10,000 watts (34,120 BTUs) on a 50-amp outlet, and ships with adapter plugs so you can connect to 40-amp stove and 30-amp dryer outlets as well as standard 208V/220V/240V high-voltage outlets.
Example: A bed bug–infested room measuring 18′ × 19′ (342 square feet), with the heater plugged into a 50-amp stove outlet, will on average behave like this:
- 90–120 minutes for the room air to reach the lethal 120° F that kills all life stages.
- Another 45–60 minutes to reach the preset 130–135° F needed for heat to penetrate furniture and baseboards — the same principle as cooking food to a safe internal temperature.
- Total treatment time of 5–6 hours on average from start, assuming a 70° F+ starting room temperature and that every pre-treatment step above has been completed.
There are no shortcuts to an effective treatment. You must work methodically to position hot air so it penetrates belongings and kills the bugs, nymphs, and eggs — eggs that would otherwise hatch later.
What temperature kills bed bugs instantly?
Your PestPro system is designed to work with an external fan that quickly distributes the hot air leaving the heater. With adequate preparation and pre-heating, a lethal temperature of 120° F (49° C) is achieved.
At that temperature, adult bed bugs dry out and die within 15 minutes. Bed bug eggs need about 30 minutes of exposure to be reliably killed.
Can you heat treat your own house for bed bugs?
Yes. You can DIY heat treat your own home using a PestPro machine. Heat has been proven repeatedly to be the most effective method for killing bed bugs without chemical insecticides — chemicals that often make the problem worse, because bed bugs long ago developed evolutionary resistance to them, much as bacteria develop resistance to antibiotics.
What do bed bugs hate?
Bed bugs avoid cold, hard surfaces like countertops and tile floors — which is why placing luggage on a bathroom floor in a hotel room is safer than on a bed or upholstered chair.
Bed bugs are drawn to warmth, including the heat inside electronics that stay slightly warm even when switched off. That is why removing outlet and switch faceplates is critical: it lets hot air reach the bugs hiding behind them. Leave electronics like TVs, radios, and computers in the treatment area — bugs often hide inside them, and treatment temperatures won’t damage the devices. Just unplug everything first.
Does washing clothes kill bed bugs?
If the water is at least 120° F, yes — hot water kills bed bugs. Since most people can’t measure their washer’s water temperature, the simpler approach is to dry clothes on HIGH for at least 20 minutes. That guarantees the bugs and eggs are killed, after which you can wash the items in any temperature.
How many heat treatments does it take to kill bed bugs?
With well-designed equipment — a separate heater and fan for flexible air distribution — and a properly prepared area, it usually takes only one treatment to kill bed bugs and eggs. There is a learning curve, but the right temperature kills all life stages the first time. There is no such thing as a heat-proof bed bug.
Do bug bombs work on bed bugs?
No — bug bombs do not kill bed bugs, and they often make the problem worse. Foggers scatter bed bugs that might have stayed in one room or piece of furniture, spreading them further through a home.
They are also dangerous: the chemicals are toxic, and the products can explode if pilot lights and other ignition sources are not safely shut off first. The Centers for Disease Control documents these risks in its case reports on total release foggers. If you share a ventilation system in an apartment, be aware of neighbors using them too.
What kills bed bugs naturally?
Heat is as natural as it gets, which makes electric bed bug heat treatment the most natural effective method available. Many “herbal” remedies — lavender, tea tree oil, and the like — may repel bed bugs, but they will not solve an infestation. Bed bugs have to die for the problem to end, and heat is the only proven natural way to kill both bugs and eggs.
What prevents bed bugs?
Bed bugs do not discriminate — they feed on human blood and can be carried into any home from almost anywhere. You can lower your risk while traveling: never let luggage touch fabric, don’t set a suitcase on the bed or a backpack on an upholstered chair, and avoid sitting on fabric in public spaces when you can.
