I had a bed bug scare, and after shopping for an exterminator found some who did not view pictures or do any kind of viewing only offered treatment that was very costly. Im so glad I contacted James who immediately told me over the phone he doubted they were bed bugs (no symptoms/bites) after sending pictures and getting some more information, he confirmed with another specialist and got back to me very quickly to tell me what they were (black book lice) and how to treat with absolutely no cost. Right at Christmas I could not be more grateful! Can’t recommend enough.

I don’t normally write reviews, but I felt I had to for ThermoPest because of how stressful our situation was. We started noticing bites a few weeks ago in our London flat and after some late night Googling I realised it was most likely bed bugs. At first, I tried sprays and washing everything, but nothing worked. It was honestly overwhelming – especially with kids in the house so I reached out to ThermoPest for help.
From the first call, they were professional and reassuring. They explained their bed bug heat treatment in London and how it kills all life stages (eggs, larvae, and adults) in one visit. The technicians turned up on time, were polite, and clearly knew exactly what they were doing. They carefully moved furniture, set up their heaters, and kept me informed throughout the process.
The difference has been night and day. After the treatment, we’ve had zero bites and could finally sleep again without worrying. I really liked that it was a chemical free method too safe for kids and pets, which was a big deal for us.

I had a bed bug issue in my London flat for around six months. Rentokil carried out five spray treatments but failed to resolve the problem. Thermopest came out and eliminated the infestation in just one visit using heat treatment. Gavin was easy to deal with throughout the process.

Absolutely. Heat treatment is one of the only proven methods that destroys bed bugs at every stage of their life cycle, including the notoriously resilient eggs. By raising the temperature of rooms to between 49-60°C, our system penetrates into furniture, walls, and cracks where sprays cannot reach. This ensures that adult bed bugs, nymphs, and eggs are all eliminated in a single process.
