London's most trusted bed bug heat treatment specialists
London is the UK's bed bug capital. High tenant turnover, HMO density, Victorian conversions with shared cavities, listed period buildings, hotels, Airbnbs and constant international travel through Heathrow, Gatwick, City and King's Cross mean bed bugs move faster here than anywhere else in the country.
Our London bed bug heat treatment service kills every adult, nymph and egg inside your property in a single 4–6 hour visit — no chemicals, no residue, no repeat spray visits. We cover all 33 London boroughs and 217+ London postcode districts, with same-day slots across Zones 1–6.
From a studio flat in Zone 1 to a five-bed Victorian in Zone 5, from a Kensington townhouse to a Stratford new-build, from a Camden Airbnb to a City hotel room — one visit, one guarantee, back in your own bed tonight.
Our Process
Industrial Bed Bug Heat Treatment Process in London
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.

The science
How London bed bug heat treatment works
London's housing stock — original floorboards, deep skirting, shared party-wall cavities, mansion-block voids, converted lofts — is perfect harbourage for bed bugs. Liquid sprays can't reliably reach eggs or deep voids, which is why so many London infestations come back after two or three chemical visits.
- 1We deploy industrial heaters into your London property and place calibrated sensors at the coolest points.
- 2Air temperature is raised to 60–65°C and held there for at least 90 minutes.
- 3Bed bugs and eggs die simultaneously in every wall cavity, floorboard gap and mattress seam.
- 4Property cools to room temperature. You're back in your own London bed 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.
