Local bed bug specialists
ThermoPest provides specialist bed bug heat treatment in Portsmouth for homeowners, tenants, landlords, letting agents and student-accommodation providers, with local coverage including Southsea, Fratton and Cosham. We treat bed bugs in homes, flats, shared houses, HMOs and managed accommodation, adapting the treatment plan to the property layout and the areas where activity has been found. The University of Portsmouth identifies Southsea and Fratton as major private student-housing areas, while Cosham broadens the page to family and commuter properties.
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
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 kills bed bugs and eggs at every life stage. Most homes are treated in a day, you can move back in 2 hours after we finish, and you are covered by our 12-week guarantee.

Local insight
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.
Pricing
Whole-property bed bug heat treatment in Portsmouth 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 rarely leave reviews, but the service I got from ThermoPest was brillaint. My flat in Notting Hill had a stubborn bed bug issue that two previous companies failed to get rid of. ThermoPest were different – super thorough, really respectful of the property, and most importantly, the bed bugs are GONE.
Richard Coulson
I honestly couldn’t recommend ThermoPest Bed Bug Treatments London more highly. When we first discovered we had bed bugs, we used a different company who failed to get rid of them and left us feeling really anxious that the problem was going to be hard (and expensive) to solve. They were going to charge almost the same again to come back, so we started looking elsewhere.
I called Gavin at ThermoPest, and right away he reassured me over the phone and gave me loads of helpful advice. He came out the very next day, was calm, kind, and put our minds at ease. What stood out most was how honest he was — it was clear he wasn’t just trying to take our money if it wasn’t necessary.
The bugs are now completely gone, and we were left well informed throughout the process. Best of all — we didn’t have to throw anything away!
If I could give 10 stars, I would. Huge thanks again to Gavin and the team at ThermoPest!
Jade Curtis
I run a small Airbnb in London, and a guest alerted me about a potential bed bug issue. I was mortified and knew I needed immediate help to protect my reputation. I called Gavin at ThermoPest, and he responded quickly with a clear plan. Highly recommend them if you’re looking for a bed bug exterminator who knows what they’re doing.
Robert Metcalfe
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.

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.
