Real treatments
With more than 20 years of combined experience, ThermoPest has treated bed bug infestations in homes, hotels and care environments across London and the UK. No two infestations are the same, which is why we tailor every treatment to the property—from family homes with fixed furniture to busy hotels requiring rapid room turnaround—to give the best chance of a lasting result.
Below are three case studies showing how we resolved complex infestations with discreet bed bug heat treatments.
Case study one
The Situation
A family in North London had been dealing with a persistent bed bug infestation after previous chemical treatments failed to clear the problem. Our inspection identified activity behind wall-mounted headboards, within mattress seams and around the skirting boards. Because the headboards were fixed directly to the wall, they created ideal harbourages that were difficult to access using conventional treatment methods.
Our Solution
Following a detailed inspection, we identified activity within the mattress seams, behind the wall-mounted headboards and around the skirting boards. As the headboards couldn’t be removed without causing damage, we first used targeted dry steam to treat these inaccessible harbourages before deploying our specialist hydronic heat treatment system. Our commercial-grade equipment circulates high-temperature heat evenly throughout the property, allowing us to raise temperatures deep into furniture, wall voids and other difficult-to-reach areas where bed bugs and their eggs hide. A residual insecticidal dust was then applied to key risk areas as part of our integrated pest management approach, helping to provide long-lasting protection after the heat treatment.
The Result
The infestation was successfully cleared in a single visit using our specialist hydronic heat treatment system and integrated pest management approach. Following treatment, the family reported no further signs of bed bug activity and could return to sleeping comfortably in their home. With our 12-week treatment guarantee and comprehensive aftercare guidance, they had real peace of mind after treatment.
Case study two
The Situation
A boutique hotel in Central London contacted ThermoPest after several guests reported suspected bed bug bites. With new bookings due to arrive the following day, management needed the affected rooms returned to service as quickly as possible while protecting the hotel’s reputation. A rapid response, complete discretion and confidence that the infestation had been properly dealt with were essential.
Our Solution
Our trained technicians carried out a detailed inspection of the affected rooms, neighbouring rooms and adjoining walls to determine the extent of the infestation. We then deployed our commercial hydronic heat treatment system overnight, circulating consistent high temperatures throughout mattresses, bed frames, upholstered furniture and hidden harbourages where bed bugs and their eggs were present. Temperatures were monitored continuously throughout the treatment to ensure every area reached lethal levels, while preventative measures were applied to neighbouring rooms to minimise the risk of migration.
The Result
The treatment was completed overnight, allowing the affected rooms to be safely returned to service the following morning with minimal disruption to hotel operations. No further guest complaints were reported, the infestation was cleared in a single treatment, and the hotel avoided the cost and reputational impact of taking multiple rooms out of service. The treatment was backed by our 12-week guarantee on qualifying treatments, giving management added peace of mind.
Case study three
The Situation
A care home in the Midlands contacted us after bed bugs spread across several residents’ rooms. Chemical sprays were not an option because of vulnerable residents with respiratory conditions and limited mobility. The challenge was to treat multiple rooms without disrupting daily care routines.
Our Solution
We worked closely with staff to schedule treatments in stages, ensuring residents were not displaced for long periods. Specialist heat systems raised temperatures in bedrooms and lounges above 50°C. For delicate furniture and medical equipment that could not be exposed to heat, we used targeted steam treatment as an additional measure.
The Result
The infestation was cleared in a single coordinated visit. Disruption to residents was kept to a minimum, staff were reassured, and management had confidence thanks to our 12-week treatment guarantee and aftercare support.
