Local bed bug specialists
ThermoPest delivers specialist bed bug heat treatment in Hertfordshire throughout St Albans, Watford and Stevenage and nearby areas. Our team works with homeowners, tenants, landlords, letting agents and property managers across homes, flats, rented properties and managed accommodation, using a treatment plan based on the property, infestation and access requirements.
Bed bugs are our specialist area rather than one of many general pest-control services. ThermoPest is a BPCA- and NPTA-member company, and our technicians use professional heat equipment with live temperature monitoring to target adults, nymphs and eggs. Our heat-led treatment plans include tailored aftercare and further treatment where required. Qualifying whole-property treatments carry a 12-week treatment guarantee, subject to the terms.

How it works
Whether you are in a St Albans terrace or a Watford flat, our treatment across Hertfordshire is led by heat. 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.
A Hatfield student HMO is a good example: bed bugs can move between let rooms through shared walls and furniture, so we look at the whole house, place sensors in bed frames, skirting boards and other tight spots, and keep the heat on until every reading stays above 50°C. Post-war homes in Stevenage and Hemel Hempstead are treated the same careful way.
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 carry our 12-week guarantee. See how our heat treatment works

Local insight
Hertfordshire sits right on London’s doorstep, and many households rely on the Thameslink, West Coast and Great Northern lines from St Albans, Watford Junction, Stevenage and Welwyn Garden City. Long daily journeys on busy trains, and busy shared offices at the other end, give bed bugs plenty of chances to travel home in bags and coats.
Stevenage, Hemel Hempstead, Hatfield and Welwyn Garden City were planned as new towns and garden cities, so much of their housing is post-war terraces, maisonettes and low-rise flats with shared walls and stairwells. Hatfield is home to the University of Hertfordshire, and its shared student houses and HMOs see new tenants every year, along with second-hand beds and sofas.
Older market towns such as Hertford, Hitchin, Berkhamsted and Bishop’s Stortford have period houses and flats above shops, where floorboards and old joinery give bed bugs extra places to hide. If you notice bites, blood spots on sheets or dark marks along mattress seams, get it looked at early.

Pricing
Whole-property bed bug heat treatment in Hertfordshire starts from £895. Your quote reflects the size and layout of the property and how far the bed bugs have spread, so a one-bedroom flat in Watford, a family house in Stevenage and a Hatfield HMO with several let rooms are each priced on what we find.
Access also matters: flats above shops in St Albans or Hemel Hempstead, upper floors without a lift and limited parking in busy town centres take more planning, and outlying villages can add travel time. Qualifying treatments carry our 12-week guarantee. Find out more on our bed bug treatment prices page.
Reviews
I contacted ThermoPest after reading about their heat treatment method and I’m so glad I did. Gavin explained the whole process and we booked in. Since the bed bug treatment it’s been over a month and we’ve had zero signs of bed bugs since.

I would highly recommend their services to anyone dealing with a bedbug issue.

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.

Very good service for a very nasty job. Would be very happy to recommend them to friends and colleagues.

FAQs

Pest control in Hertfordshire is handled by the district and borough councils, such as St Albans City and District Council, Watford Borough Council, Dacorum Borough Council and Stevenage Borough Council. What they offer varies and can change, so check your own council’s website. Our guide to council vs private bed bug treatment explains the differences.
Yes. We treat shared houses, HMOs and student lets used by students at the University of Hertfordshire. With several let rooms in one house we usually treat the whole property, because bed bugs move between rooms on bags, bedding and furniture.
It depends on your tenancy and when the bed bugs appeared. Landlords are often responsible for an infestation that was there before you moved in or that spreads between flats, so report signs to your landlord or letting agent in writing straight away. Our guide on what to do if your landlord won’t treat bed bugs sets out what to do next.
Yes, they can move through gaps around pipes, sockets and skirting boards into neighbouring flats. When we treat a flat we will advise whether the flats next door, above or below should be inspected too. Our guide on whether bed bugs can come from neighbours explains more.
No. ThermoPest is based in London and we travel out to homes and businesses across Hertfordshire, from Watford and St Albans to Stevenage, Hertford and Bishop’s Stortford. Our technicians bring all the heat treatment equipment with them in discreet unmarked vans.
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 carry our 12-week guarantee. See our bed bug treatment prices page for the full terms.
