Know the signs
Despite their small size and excellent ability to hide and stay out of sight, there are several telltale signs that may indicate that your property is infested with bed bugs.
Because these insects are nocturnal and adept at squeezing into the narrowest crevices such as; mattress seams, electrical sockets, and behind skirting boards, an infestation often goes unnoticed.
Some of the most common signs include:
If you notice any of the signs listed above or if you suspect that your property is infested with bed bugs, it’s time to arrange a professional inspection.

Why ThermoPest
We’re a specialist bed bug heat treatment company serving London, with experience treating everything from Victorian terraces and high-rise flats to hotels, HMOs and large residential properties.
Bed Bug Heat Treatment Specialists — bed bugs are our core focus, and other pest control companies call on us for specialist heat treatments.
Built for London Properties — extensive experience treating flats, shared buildings, HMOs, hotels and complex multi-room infestations.
12-Week Treatment Guarantee — our qualifying bed bug heat treatments include 12 weeks of aftercare protection.
Heat vs other methods
In London’s dense converted flats, bed bugs spread through shared wall voids, and many local strains are now immune to chemical sprays.
Our Heat Treatment gets around these defences, penetrating deep into the structure to kill bed bugs at all life stages (egg, nymph, adult), where chemical treatments alone often fail.
Faster Results – Monitored heat targets all life stages, with further treatment where required and aftercare to support the result.
Low Chemical Use – No harmful residues or strong odours left behind.
Kills All Life Stages – Heat destroys eggs, nymphs, and adults in one process.

How it works
We follow the same rigorous process for every property we treat — thorough, discreet and planned around your property, with practical aftercare and follow-up where required. Every job starts with a full assessment, followed by a managed heat treatment day and aftercare support to prevent reinfestation.

Preparation
Preparing your property before our specialist arrives will help ensure the treatment runs smoothly and delivers the best results. It also reduces the risk of any disruptions on the day.
Don’t worry — our team will guide you through everything beforehand. It’s simpler than you might think.
Here’s a guide to give you an idea of what’s required.
Do note that all occupants, including your pets, will need to vacate the property while the heat treatment is taking place. Once the treatment is completed, our team will let you know when it’s safe to go back indoors.

Case study
A 4-star hotel in Covent Garden faced a critical situation when a guest reported bites.
Relying on standard chemical protocols would have required a two-week room closure, risking over £3,000 in lost revenue.
Understanding the critical cost of downtime, our team responded the same day with a rapid-action integrated treatment plan. By combining heat, steam, and Diatomaceous Earth, we sped up the treatment process, bypassing the need for multi-day chemical protocols. The infestation was fully resolved within a four-hour window, allowing housekeeping to turn the room around and welcome a paying guest that very same evening.
The Result
The infestation was cleared in a single visit. With our 12-week treatment guarantee, the hotel had extra peace of mind after the treatment.
Reviews
ThermoPest delivered on their promise!
James who initially came out was very professional and the teams work has been a relief after trying another company (with a big name) which had failed to get us rid of the bugs and have charged us an arm and a leg without any guarantee.
Great customer service, a guarantee and are very flexible. I highly recommend their service to anyone who is dealing with bed bugs in London. Thank you so much for all your help.
Great service experience
I've tried to get rid of bed bugs..
I’ve tried to get rid of the bed bugs (after unfortunately bringing them back from Thailand) myself, and I tried two other companies who cane out and sprayed and this was unsuccessful. I contacted these and someone came out the next day to survey my home and the treatment was booked in for a few days time. Safe to say I no longer have bed bugs and they even give you a guarantee. Thanks James and team.

FAQs

Bed bugs don’t randomly find themselves in your property. They are almost always brought in by visitors, second-hand furniture, or travel clothes that have been exposed to an infested environment. To prevent bed bugs from returning after a heat treatment, make sure that you:
To help with prevention, we can also install bed bug monitors in your property, which will help detect any early activity and allow you to take action before a minor issue turns into a full infestation.

The cost of heat treatment in London varies based on several factors, including the size of the area and the severity of the infestation. Rather than using a simple “per room” rate, full-property treatments start from £895.
Pricing is determined by property size, infestation severity, and the total time required to treat the problem properly. This ensures we specify the correct heat levels, professional equipment, and technician time from the outset to give your treatment the best chance of success.
To receive an accurate, bespoke quote for your property, one of our trained professionals will conduct a comprehensive initial assessment with you over the phone. Please get in touch at your earliest convenience by calling 080 8189 2310 or emailing office@pest.co.uk.
Yes — ThermoPest provides bed bug heat treatments for residential, commercial, and hospitality properties across London. Our discreet service is ideal for hotels, flats, and businesses that need fast, effective results with minimal disruption.
Yes, the London transport network (TfL) is a common way for “hitchhiker” pests to travel. The advantage of our Heat Treatment is that we treat your luggage, work clothes, and coats alongside your room through a tailored treatment plan. This ensures that any bugs you may have brought home on your commute are treated at the same time, helping to break the cycle.
Our primary method raises the temperature to a level that kills bed bugs and their eggs. In certain scenarios, we may add a low level of targeted insecticide only where it’s needed. Any products we use are strictly regulated and approved for professional use, and as members of the BPCA and NPTA we follow recognised industry standards. All people and pets must be out of the property during heat treatment, and you can usually return after 2 hours unless your technician advises otherwise.
No, heat treatment won’t damage your furniture or electronics. To give you extra peace of mind, during the initial assessment of your property, our team will identify all sensitive items before the heat treatment begins.
