Our bed bug heat treatment process is the same whether you’re in a terraced house in Southsea or an HMO near the naval base — thorough, discreet and completed in a single visit.
Our technicians raise the temperature of your property to between 49°C and 60°C, maintaining that lethal range for a sustained period. This level of heat penetrates deep into mattresses, furniture joints, skirting boards and wall voids — every place bed bugs and their eggs hide.
Unlike chemical treatments which can miss hidden life stages and require multiple visits, heat treatment eliminates the infestation completely in one day. You can return to your property the same evening.

Portsmouth has a distinctive bed bug risk profile unlike most UK cities. The combination of a large naval base and military community, busy international ferry terminal, significant student population and high proportion of HMO rental properties creates multiple simultaneous pathways for infestation spread.
Southsea and Fratton have particularly dense terraced housing where infestations can spread between neighbouring properties quickly. The city’s transient population — naval personnel on rotation, students arriving and departing annually, and international ferry passengers — means infestations are introduced and spread at higher rates than in more settled communities.
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.
We contacted ThermoPest for bed bug treatment in London after finding signs of activity at home. The technicians recommended a heat treatment, which was perfect for us as we wanted to avoid chemicals. The process was efficient, discreet, and cleared the problem in just one visit.

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.

Portsmouth has above-average bed bug risk driven by several factors unique to the city. A high proportion of HMO and shared rental properties serving the naval community and students, a busy port and ferry terminal with international passenger traffic, and a large student population across the University of Portsmouth all contribute. The city's dense terraced housing in Southsea and Fratton also enables faster spread between properties.
Yes — the University of Portsmouth has a large student population and student housing in Southsea, Fratton and Buckland is a common treatment area for us. We also regularly treat naval accommodation and HMOs serving the armed forces community. See our Letting Agents page for 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. Portsmouth has a large private rental sector serving naval personnel, students and service workers — landlord responsibility questions are common here. We provide full treatment documentation for both parties. Call us for impartial advice on your specific situation.
Yes — Portsmouth International Port is one of the UK's busiest ferry terminals with routes to France, Spain and the Channel Islands. International ferry travel is a well-documented source of bed bug spread and Portsmouth residents who travel regularly or work in the port sector face elevated exposure risk. Hotels near the port are also common treatment cases.
