Local bed bug specialists
ThermoPest delivers specialist bed bug heat treatment in Hertfordshire throughout St Albans, Watford and Stevenage and nearby areas.

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.

Local insight
Hertfordshire’s position directly north of London makes it one of the higher-risk commuter counties for bed bug exposure. Residents across St Albans, Watford, Hemel Hempstead and Stevenage frequently travel into central London — where bed bug infestation rates are the highest in the UK — creating regular exposure risk that other counties don’t face to the same degree.
The county also has a substantial student population centred on Hatfield and St Albans, and a large rental market catering to young professionals commuting into London. High-turnover rental properties and shared HMOs are among the most common treatment types we see in Hertfordshire.
If you’ve noticed bites, blood spots on bedding or small dark marks on your mattress seams, don’t wait. Early treatment is faster, less disruptive and less expensive than dealing with a fully established infestation.
Pricing
Whole-property bed bug heat treatment in Hertfordshire starts from £895. Your final quotation depends on the property’s size and layout, the extent of the infestation, access, preparation requirements and any areas requiring additional treatment.
Our treatment combines professional heat equipment with live temperature monitoring to target bed bugs at every life stage, including adults, nymphs and eggs. Where required, we also use targeted residual treatments and monitoring to help reduce the risk of surviving activity. Qualifying whole-property treatments include a 12-week treatment guarantee, subject to terms. See our bed bug treatment pricing for current prices, what is included and full guarantee information.
Reviews
I hired Thermopest after multiple unsuccessful attempts of having sprays with other companies. They completed the work in a single visit and I have not had an issue since. I personally think its worth the money and wish I had hired them initially. The whole team were helpful from speaking to Gavin on the phone to the team who came out to visit. I would recommend them to anyone having an issue with bed bugs. Thanks again.

ThermoPest handled our bed bug issue in our flat quickly. The London heat treatment service was worth every penny – no more bites and we can finally sleep peacefully again.

Writing my review now from the treatment I had in early feb this year, I had heat treatment and the lads were so friendly, Gavin was amazing and answered all my questions constantly in email, I am based all the way in Northumberland and he still came through, They were super thorough and Touch wood, I’m still bedbug free to this day!

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.

Hertfordshire's position as a major London commuter county means residents are frequently exposed to London's high bed bug infestation environment. Regular commuting on the Tube and Thameslink, combined with the county's large rental sector and high-turnover student properties in Hatfield and St Albans, contribute to above-average infestation rates across the county.
Yes — the University of Hertfordshire in Hatfield and the University of St Andrews in St Albans generate significant student housing demand. We work with students and landlords across the county. See our Letting Agents page for more on our landlord services.
In most cases the landlord is responsible for treating a pre-existing infestation, while tenants may be liable if they introduced the infestation after moving in. Hertfordshire has a large commuter and rental market — landlord responsibility questions arise frequently here. We provide full treatment documentation for both parties. Call us for impartial advice on your specific situation.
Yes — Hertfordshire is one of the UK's most intensively commuter-connected counties, with fast rail links to London St Pancras, Kings Cross, Liverpool Street and Moorgate. Regular commuting into central London and the City increases exposure risk. If you travel regularly to London for work and have noticed unexplained bites, a professional inspection is the sensible next step.
