Our Process
Industrial Bed Bug Heat Treatment Process in Hampstead & Swiss Cottage
At Extreme Heat To Kill Bed Bugs, 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.

Hampstead & Swiss Cottage pest guide
Carpet and clothes moths in Hampstead & Swiss Cottage: a local damage guide
Clothes and carpet moth damage is a quiet, expensive problem in Hampstead & Swiss Cottage NW3. Short-term lets and Airbnb stock near Hampstead & Swiss Cottage town centre mean a high turnover of guests, suitcases and bedding — the single biggest local driver of repeat callouts. We see ruined wool rugs, cashmere drawers and stair carpets in homes across Hampstead & Swiss Cottage every month — almost always caught too late.
Identifying the moth in your Hampstead & Swiss Cottage home
Almost every Hampstead & Swiss Cottage infestation is one of two species: the case-bearing clothes moth (small grey-brown larvae in tiny silk "cases" on carpet edges) or the common clothes moth (pale larvae spinning loose webbing in wardrobes). Both eat keratin — wool, silk, cashmere, feathers — and both prefer the still, dark spots under furniture in homes near Hampstead & Swiss Cottage town centre.
Where Hampstead & Swiss Cottage homes see the first damage
- Bald patches on wool carpets under sofas, beds and inside fitted wardrobes.
- Holes in jumpers, suits, dresses and scarves — often only one or two items hit first.
- Fine webbing or grain-like droppings along skirting boards.
- Live larvae: 6–10 mm, cream-coloured, sometimes inside a small silk tube.
- Small grey-gold adult moths fluttering up walls when curtains are drawn.
Why pheromone traps alone won't work
Pheromone traps are a useful monitor, not a treatment. They only attract adult males, while the larvae chewing your Hampstead & Swiss Cottage carpets are completely unaffected. Heat is the only single-visit method that reaches eggs and larvae inside the underlay and behind the skirting boards.
Three things to do today in your Hampstead & Swiss Cottage home
- Stop hoovering the affected room — it spreads eggs to clean areas.
- Bag up wool/cashmere items and keep them sealed until treatment day.
- Don't apply mothballs to children's bedrooms — they're a respiratory irritant.
- Photograph damaged items for any contents insurance claim.
Quick questions from Hampstead & Swiss Cottage households

A typical Hampstead & Swiss Cottage job takes 4–6 hours from arrival to handover, including the full kill cycle and cool-down.
Can I keep my clothes in the wardrobe?
Yes — leaving them in place is preferred, so any eggs or larvae on the fabric are killed at the same time.
