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.
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 bypasses these defences completely, penetrating deep into the structure to eradicate all life stages ( egg, nymph, adult ), where traditional chemical treatments fail.
Faster Results – One treatment is usually enough, while chemical sprays often require 4–5 repeat visits.
Low Chemical Use – No harmful residues or strong odours left behind.
Kills All Life Stages – Heat destroys eggs, nymphs, and adults in one process.
We follow the same rigorous process for every property we treat — thorough, discreet and completed in a single visit. Every job starts with a full assessment, followed by a managed heat treatment day and aftercare support to prevent reinfestation.

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 accelerated the eradication 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 60-day guarantee, the hotel had complete reassurance that the problem wouldn’t return.
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.

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 £795.
Pricing is determined by property size, infestation severity, and the total time required to eradicate the problem properly. This ensures we specify the correct heat levels, professional equipment, and technician time from the outset to guarantee a successful result.
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.
