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.
Excellent service, super responsive and delivered exactly what was needed.

After moving into a new flat in London, I started getting bites. I called ThermoPest, and they were round in no time. Their heat treatment was a game-changer—no chemicals, just pure heat to zap the pests. The lads were proper friendly and made sure I understood the process. Not a single bite since. Highly recommend!

I feel incredibly fortunate to have found this service. This company has been able to deal with the bed bug issue very effectively.
James who initially came out was very professional and the teams work has been a relief after trying another company (with a big name) which had failed to get us rid of the bugs and have charged us an arm and a leg without any guarantee.
Great customer service, a guarantee and are very flexible. I highly recommend their service to anyone who is dealing with that type of issue. Thank you so much for all your help.

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.

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.
