The leading bed bug heat specialists in Portsmouth. Fast, discreet, and guaranteed removal.
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.

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 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.
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. Treatments include a 60-day guarantee, subject to terms. See our bed bug treatment pricing for current prices, what is included and full guarantee information.
Needed a bed bug treatment in London for a flat we rent out. The process went smoothly and overall was impressed with how it was handled.

I was skeptical about heat treatments for bed bug extermination, but Gavin at ThermoPest reassured me every step of the way. I live in a flat in central London, and the infestation was starting to spread to other rooms. The team acted quickly and discreetly, and the results speak for themselves—complete removal in one session.
Leo Jones
Unlucky, I found some bed bugs in one of my bed rooms. Luckily, I found James’ contact number, I called him and explained the situation, he gave me very reasonable quotation and guaranteed that he will solve the problem. He came next day giving first treatment and came again after 7 days. After two treatments, the bed bugs were all killed and I never had the same issue again.
I am so pleased with their professional service, and high recommend him to anyone who has the same problem.
Megan
Amazing service from James and the team. Moved into a house where there were bedbugs, James and team got rid of them and also put up with my constant texts looking for advice and reassurance. I will definitely recommend you 100%

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.
