Our Process
Industrial Bed Bug Heat Treatment Process in Eltham & Mottingham
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.

Eltham & Mottingham pest guide
Carpet and clothes moths in Eltham & Mottingham: a local damage guide
Carpet moths are the single most under-diagnosed pest in Eltham & Mottingham. Student lets and shared housing in Eltham & Mottingham create the perfect harbourage: lots of bedding, lots of new occupants, very little co-ordinated treatment. Households assume it's "just wear" on the carpet until they pull the sofa out and find a bald patch the size of a dinner plate.
The two moths you'll meet in Eltham & Mottingham
In Eltham & Mottingham the case-bearing clothes moth dominates carpets and the common clothes moth dominates wardrobes. Both eat the same natural fibres but live in completely different places, which is why a single can of spray rarely finishes the job.
Early warning signs in a Eltham & Mottingham property
- 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 traps aren't enough on their own
In Eltham & Mottingham we regularly inherit jobs where the household has been running traps for a year and the damage has still got worse. Traps catch the obvious bit — the flying males. The hidden 95% (eggs, larvae, pupae) needs heat to finish off in one pass.
What Eltham & Mottingham households should do straight away
- 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 Eltham & Mottingham households
How long does a moth treatment take in Eltham & Mottingham?
A typical Eltham & Mottingham 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.
