Step-by-Step: How Our Bed Bug Heat Treatment Works
Step 1: Property Assessment and Planning
Before treatment begins, the property is assessed to understand:
- The type of building (flat, terraced house, HMO, hotel, or serviced accommodation)
- The level and spread of the infestation
- Room layout, contents, and furniture
- Any heat-sensitive items that require preparation
London properties often include shared walls, compact rooms, and heavy furnishings. The assessment ensures the treatment plan is safe, effective, and suitable for the property.
Preparation steps are explained in full in our Bed Bug Treatment Preparation Guide
Step 2: Controlled Heat Treatment
Specialist heaters are installed to raise temperatures throughout the treated space to between 50°C and 60°C, the proven lethal range for bed bugs and their eggs.
Unlike sprays or surface treatments, heat penetrates:
- Mattresses and upholstered furniture
- Bed frames and headboards
- Skirting boards and cracks
- Wardrobes, drawers, and soft furnishings
- Electrical voids and hard-to-reach harbourages
This is the core of our professional bed bug heat treatment service in London
Step 3: Continuous Temperature Monitoring
Wireless temperature sensors are placed throughout the property to monitor:
- Air temperature
- Surface temperature
- Cold spots behind furniture or in corners
Temperatures are maintained at lethal levels for a defined period to ensure complete eradication, including eggs. This monitoring is essential for successful, single-visit treatments.
Step 4: Targeted Residual Control Where Needed
In some situations, a light, targeted residual treatment may be applied to specific high-risk areas such as bed frames or skirting boards. This is only used where appropriate and never replaces heat as the primary control method.
Information about treatment outcomes and guarantees is covered in our Aftercare and Guarantee page
Step 5: Treatment Completion and Verification
Once all monitored areas have reached and sustained lethal temperatures:
- Equipment is removed
- Rooms are allowed to cool safely
- Clear guidance is provided before re-occupation
In most London properties, one treatment is sufficient when preparation guidance is followed correctly. Typical treatment timelines are explained on our How Long Bed Bug Treatment Takes page
Why Heat Treatment Is Effective for Bed Bugs
Heat treatment addresses the main reasons bed bug infestations persist:
- Bed bug eggs are resistant to many insecticides
- Bed bugs hide deep within furniture and building structures
- Chemical resistance is increasingly common
Heat treatment:
- Kills bed bugs and eggs in one process
- Reaches hidden harbourages sprays often miss
- Reduces the need for repeated treatments
This makes heat treatment a preferred solution for London rental properties, hotels, HMOs, and residential homes.
Is Bed Bug Heat Treatment Safe?
Yes, when carried out by trained professionals.
Temperatures are carefully controlled, and preparation steps ensure heat-sensitive items are protected. The process does not involve fumigation or widespread chemical spraying.

FAQs
How does bed bug heat treatment kill bed bugs?
Heat treatment raises temperatures above 50°C, causing fatal damage to bed bugs and their eggs. Sustained exposure ensures insects hidden deep within furniture and structures are also eliminated.
Can bed bugs escape during heat treatment?
No. Professional heat treatment warms the entire treated area evenly, removing cooler escape zones and preventing bed bugs from moving away from the heat.
Is heat treatment better than chemical bed bug treatments?
In many cases, yes. Heat kills eggs, avoids resistance issues, and usually works in a single visit, whereas chemical treatments often require multiple applications.
Does heat treatment work in London flats and apartments?
Yes. Heat treatment is particularly effective in London flats where bed bugs hide in walls, furniture, and shared structural areas.
Where can I find pricing and preparation information?
Pricing is explained on our Bed Bug Treatment Cost page, and preparation steps are covered in our Preparation Guide.
Summary
Bed bug heat treatment works by raising room temperatures high enough to kill bed bugs and their eggs. Professional monitoring ensures all hiding places reach lethal temperatures. Heat treatment is effective, chemical-light, and commonly resolves infestations in a single visit.
