How it works
Bed bugs and their eggs die when held above about 50°C for long enough. We heat rooms to 50–60°C and hold that heat until the hardest-to-reach spots stay above 50°C. Our technicians place temperature probes in the places bed bugs favour, such as mattress seams, bed frames, headboards and sofa joints, and watch the readings live so no room is left short.
A typical Dorset job might be a seafront guest house in Weymouth with several letting rooms over three floors, or a cottage near Bridport with thick walls and low beams. We plan the heat room by room so every bedroom reaches temperature, and we give owners and guests clear preparation and aftercare advice, including how to manage bookings around the treatment.
Most treatments are completed within a day, and you can usually move back in after about 2 hours, unless your technician advises otherwise. Qualifying treatments are covered by our 12-week guarantee. See how our heat treatment works

Local insight
Dorset is a largely rural county with a busy visitor economy. Weymouth, Swanage and the towns along the Jurassic Coast fill with holidaymakers every summer, and many properties are holiday lets, B&Bs, guest houses or static caravans with a steady turnover of guests. Bed bugs travel in luggage and on clothing, so places with frequent changeovers can pick them up from visitors without anyone noticing at first.
Away from the coast, market towns such as Dorchester, Bridport, Wimborne and Blandford Forum have a mix of older terraces, flats above shops and rented family homes, alongside thatched cottages and converted farm buildings in the villages. Older homes with timber floors, beams and gaps around skirting give bed bugs plenty of places to hide, and second-hand furniture bought locally or online can bring them in.
If you have noticed bites, small blood spots on bedding or dark marks along mattress seams, act early. For holiday let and B&B owners in particular, treating quickly means fewer cancelled bookings and less disruption to guests.

Pricing
Whole-property bed bug heat treatment in Dorset starts from £895. The final price depends on the size and layout of the property, how far the infestation has spread and how much preparation is needed. A guest house or B&B with several letting rooms takes more equipment and time than a two-bedroom flat in Dorchester, and holiday lets, static caravans and rural properties down narrow lanes can affect how we set up on the day.
We confirm the price after a survey or a detailed conversation about the property, so owners, landlords and tenants know what is included before we travel out. Qualifying treatments carry our 12-week guarantee. See our bed bug treatment prices for what is included and the full guarantee terms.
Reviews
Bed bugs are definitely not the kind of present you want to bring back from holiday but unfortunately we did- even after staying in a nice hotel chain! These guys offered a guarantee and a great price so we decided to go with them. It was a great decision as it took only only visit to get rid of the issue. Worth every penny. Plus we have not needed to call them back at all. Thanks to Jamie and team for sorting.

I was skeptical about heat treatments for bed bug extermination, but Gavin at ThermoPest reassured me every step of the way. I live in a flat in central London, and the infestation was starting to spread to other rooms. The team acted quickly and discreetly, and the results speak for themselves—complete removal in one session.

Thermopest came out to do a bed bug heat treatment, I was told it would get rid of the problem in one visit. However a few days after the treatment we noticed live bed bugs. I called Gavin and he was able to send back another set of technicians to complete a second treatment. Since then we have been bed bug free, I will give 5 star since dealing with Gavin helped the process to go well.
