Our Process
Industrial Bed Bug Heat Treatment Process in Kingsbury & Colindale
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.

Kingsbury & Colindale pest guide
Bed bugs in Kingsbury & Colindale: how local infestations start and how to end them
Bed bug callouts in Kingsbury & Colindale (NW9) have roughly doubled since 2023. Period conversions and HMOs around Kingsbury & Colindale town centre share walls, voids and lift shafts, which is why infestations here rarely stay in one flat for long. Most of what we see in Kingsbury & Colindale is preventable with the right first response, but almost every household we visit has tried something that made the problem worse before ringing us.
Where Kingsbury & Colindale infestations actually start
Almost every Kingsbury & Colindale job we attend traces back to a single introduction — a hotel suitcase, a returning student, a second-hand sofa, a guest's overnight bag. From there the bugs follow CO₂ at night and move between rooms along skirting voids and floorboard gaps.
Signs your Kingsbury & Colindale property has bed bugs
- Itchy bites in a line or cluster, usually on arms, shoulders or ankles after a night's sleep.
- Tiny black dots (digested blood) along mattress piping, headboard joints or skirting boards.
- A faint sweet, musty smell in heavily infested bedrooms.
- Small pale-yellow shed skins in bed frames, behind picture frames or inside electrical sockets.
- Live insects the size of an apple pip, flat and reddish-brown, hiding in seams and crevices.
Why Kingsbury & Colindale households switch to heat
Kingsbury & Colindale has a mixed property stock — period conversions near Kingsbury & Colindale town centre, modern flats in Kingsbury & Colindale and HMOs in Kingsbury & Colindale. Chemical sprays struggle in all three because bed bugs hide in voids the spray never reaches. A controlled rise to 50–60°C kills every life stage, including eggs, inside one visit — without dismantling anything.
Mistakes to avoid before treatment in Kingsbury & Colindale
- Don't bin your mattress before treatment — moving it spreads bugs to other rooms and to the bin store.
- Don't fog or bomb the room — it scatters survivors deeper into wall cavities.
- Don't sleep in another room of the same flat — bed bugs follow CO₂ and will simply move with you.
- Don't apply petrol, paraffin or essential oils. They don't work and they're dangerous.
