Real heat treatments on real UK homes
Our commercial-grade indirect-fired heaters push clean, dry 60°C+ air through insulated ducting straight into your property — killing every bed bug, egg and nymph in a single visit.

60°C+ delivered on site
Our diesel-powered EC85 industrial heaters generate the huge thermal output needed to lethally heat an entire home from the outside in.

Whole-property coverage
Twin insulated ducts feed hot air into multiple rooms at once so every void, skirting and mattress seam hits kill temperature together.

Clean, dry, chemical-free heat
Indirect-fired combustion means only clean warm air enters your home — no fumes, no residue, safe for children, pets and listed buildings.

Sealed & monitored
We seal entry points and place wireless probes at the coldest spots — holding 60°C+ until every bug and egg is dead. No cold spots, no survivors.

What a bed bug infestation actually looks like
Bed bugs (Cimex lectularius) are reddish-brown, apple-pip-sized insects that feed on human blood at night and hide in seams, crevices and upholstery by day. The earlier you spot the signs below, the faster heat treatment can end the infestation in a single visit.

Mattress seams
Adults, nymphs and dark faecal spots gather in the piping and label seams of mattresses — the classic first place to check.

Pillows & bedding
Small black dots and rust-coloured smears on pillows and sheets are digested blood — a tell-tale sign bugs are feeding nearby.

Headboards & furniture
Cream-coloured eggs, shed skins and live bugs hide in tufted headboards, bed frames and nearby upholstered furniture.

Bites on skin
Itchy red welts in clusters or straight lines — often on arms, neck and shoulders — frequently appear before the bugs are seen.
Recognise any of these signs? Don't wait — bed bug numbers double roughly every 16 days. Call 0203 488 2530 for same-week single-visit heat treatment.
Industrial Bed Bug Heat Treatment Process
At Extreme Heat Force UK, we specialise in carrying out professional industrial heat treatments designed to eliminate bed bugs at all life stages — including eggs, nymphs and adults — in a single visit. Unlike traditional chemical treatments, our process uses carefully controlled heat to penetrate deep into mattresses, furniture, skirting boards, cracks, crevices and other harbourage areas where bed bugs hide.
Our system combines high-powered indirect diesel heaters, American-made electric heat treatment equipment and commercial air movers to raise room temperatures to lethal levels while ensuring heat is distributed evenly throughout the property.
Initial Inspection and Preparation
Before treatment begins, our technicians carry out a detailed inspection of the affected rooms to identify bed bug activity, harbourage areas and any potential heat-sensitive items that may require removal.
Temperature monitoring probes are strategically placed throughout the property to monitor temperatures during the treatment process. This allows us to ensure all areas receive sufficient heat exposure while maintaining complete control of the treatment environment.
Industrial Heat Generation
Our primary heat source consists of commercial indirect diesel-fired heaters capable of producing large volumes of clean, dry heated air. Because the combustion process remains separate from the heated airflow, no fumes, smoke or combustion gases enter the treated rooms.
The heated air is ducted directly into the treatment areas, allowing us to rapidly increase temperatures throughout the property.
In addition to our diesel equipment, we utilise specialist American electric heat treatment machines to supplement and maintain temperatures in difficult areas where additional heat concentration may be required. These professional-grade systems help ensure complete heat penetration throughout the structure.
Air Movement and Heat Distribution
Simply heating a room is not enough to eliminate bed bugs effectively. To achieve complete treatment coverage, we deploy multiple commercial air movers throughout the property.
These high-volume air movers continuously circulate heated air around furniture, beds, wardrobes, sofas, skirting boards and room contents. This process eliminates cold spots and ensures heat reaches areas where bed bugs may be hiding.
By constantly moving the heated air, we create an even thermal environment that allows lethal temperatures to penetrate deep into mattresses, upholstered furniture, wall junctions and other difficult-to-reach locations.
Achieving Lethal Temperatures
Throughout the treatment, temperatures are carefully monitored using thermal probes and thermal imaging equipment.
The objective is to raise target areas to temperatures between 60.5°C and 65°C, which are proven to be lethal to bed bugs and their eggs. Once target temperatures are achieved, they are maintained for a sufficient period to ensure effective eradication throughout the treated areas.
Our technicians continually monitor and adjust equipment throughout the process to ensure optimum heat distribution and treatment effectiveness.
Treatment Duration
Most residential heat treatments take between 4 and 6 hours depending on the size of the property, level of infestation and room configuration.
During this time, our technicians remain on site to monitor temperatures, reposition equipment if necessary and ensure the treatment progresses safely and effectively.
Cooling and Final Inspection
Once the treatment cycle has been completed, the equipment is gradually shut down and the property is allowed to cool naturally.
A final inspection is then carried out to confirm treatment completion and verify that all target areas have achieved the required temperatures.
Our technicians will provide aftercare advice and answer any questions regarding post-treatment expectations.

Why heat works where sprays fail
Bed bug eggs are wrapped in a waxy shell that liquid pesticides can't reliably penetrate. That's why most spray treatments leave eggs alive — they hatch a week later and the infestation rebuilds. Heat kills every life stage in one cycle.
- 1We deploy industrial heaters and place sensors at the coolest points in the property.
- 2Air temperature rises to 60–65°C and is held there for at least 90 minutes.
- 3Bed bugs and eggs die simultaneously. We monitor every sensor throughout.
- 4Property cools to room temperature. You're back in your own home that evening.

Important Information
Our industrial heat treatment is one of the most effective ways of eliminating bed bugs. However, as with any process involving high temperatures, there are thousands of different household items, materials, finishes and possessions that may react differently to heat. It is simply not possible to identify or list every item that could potentially be affected.
While we take every reasonable care throughout the treatment and provide a preparation guide to help minimise any risks, we cannot accept responsibility for damage to any heat-sensitive items, materials or belongings. The purpose of the treatment is to safely eradicate the infestation, and by proceeding with the treatment you acknowledge and accept this.
If you are unsure whether an item may be sensitive to heat, we recommend removing it from the treatment area before our arrival.
Things to Be Aware Of During a Professional Heat Treatment
Professional heat treatments are a highly effective way of eliminating bed bugs. In the vast majority of cases, properties are treated without any problems. However, as with any process that involves raising temperatures, some materials may react slightly, particularly if they are older, already damaged or poorly installed.
On rare occasions, the following may occur:
- Existing hairline cracks in plaster or ceilings may become slightly more noticeable.
- Older or loose plaster may develop small cracks.
- Previously damaged or loose paint may flake.
- Decorators' caulk around skirting boards or door frames may separate slightly.
- Loose wallpaper edges or seams may lift.
- Some silicone sealants may soften or separate.
- Natural wood and wood-based products may expand or contract slightly before returning to normal.
- Poorly fitted laminate or engineered flooring may experience minor movement.
- Veneered or MDF furniture with ageing adhesives may occasionally show lifting around the edges.
- Some plastic or faux wood blinds may be affected by prolonged exposure to heat.
To help protect your belongings, please remove all heat-sensitive items listed on the preparation checklist before we arrive. If you are unsure about any particular item, please contact us before your appointment and we will be happy to advise.
