Living in London offers incredible opportunities, but it also means dealing with unique challenges. High-density living, constant international travel, and busy public transport make our city a global hotspot for bed bugs. If you’ve discovered an infestation, you know the stress, anxiety, and sleepless nights that follow. You want a solution that is fast, total, and discreet.
You’ve likely heard of chemical sprays that require multiple visits and still might not work. But there is a better way.
Welcome to the definitive guide to bed bug heat treatment in London. As London’s BPCA-accredited heat treatment specialists, we at ThermoPest believe in solving your bed bug problem in a single day, not stretching it out over weeks. For a complete solution, we also recommend professional bed bug cleaning in London to remove dead bugs and stains after your treatment.
This guide will explain what heat treatment is, why it’s the superior choice for London properties, and how our 1-Day Solution gets you back to normal, faster.

What is Bed Bug Heat Treatment?
Heat treatment is a chemical-free pest control method that eradicates a bed bug infestation by raising the temperature of your property to a lethal level.
At ThermoPest, our specialist technicians use industrial-grade heaters to safely and methodically heat every corner of the affected rooms to temperatures between 48°C and 60°C. This intense heat penetrates deep into furniture, mattresses, box springs, wall cavities, and floorboards—places where bed bugs hide and chemicals can’t reach. For tips on how to prevent bed bugs, explore our expert guidance.
The crucial difference? This heat kills all life stages of the bed bug, from adult insects to nymphs and, most importantly, their eggs. This thorough approach enables complete eradication in a single visit.
Heat Treatment vs. Chemical Sprays: A London Comparison
For London homeowners, landlords, or hotel managers, choosing the right bed bug control method is essential. You need minimal disruption and guaranteed results. Here’s why heat treatment is the clear winner over traditional chemical sprays in a city like ours.

The ThermoPest 1-Day Solution: Our London Process
We’ve refined our process to be the most efficient and effective in London. Here’s what to expect when you choose ThermoPest.
Step 1: The Initial Consultation
It starts with a phone call. You’ll speak directly to one of our pest control experts (not a call centre) who understands London’s unique properties. We’ll conduct a thorough inspection to identify bed bug activity, including shed skins, hiding spots, and signs of infestation. We’ll assess the scale of your infestation, discuss the property layout (flat, terraced house, hotel), and provide a clear, no-hidden-fees quote tailored to your needs.
Step 2: Pre-Treatment Preparation
Preparation is key to a successful heat treatment process. We provide you with a simple checklist of things to do before our team arrives. This typically involves removing heat sensitive items (like aerosols, wax, or certain artworks) and lightly decluttering to ensure heat can circulate everywhere, including hard to reach areas such as electrical outlets and cracks.
Step 3: The 1-Day Heat Treatment
Our BPCA-certified team arrives discreetly in an unmarked vehicle.
- Setup: We strategically place industrial heaters and temperature-monitoring sensors throughout the infested area.
- The Heat-Up: We gradually raise the temperature to the lethal range and maintain it for a precise duration to kill bugs at all life stages.
- Monitoring: We monitor temperatures in real-time from a central hub, checking sensors placed in the deepest cold spots (like inside mattresses, box springs, or sofas) to ensure thorough eradication.
- Cool Down: Once the treatment is complete, we safely remove our equipment and allow the property to cool.
You can typically re-enter your home by the end of the day, completely bed bug-free.
Step 4: Our 60-Day Guarantee and Follow-Up
We stand behind our treatment with a 60-Day Guarantee. If you notice any signs of bed bug activity within 60 days, we’ll return and re-treat the area at no extra cost. We also recommend routine inspections to prevent future infestations and ensure lasting peace of mind.
