Bed bug heat treatment

Heat, spray, or both?

Bed bugs have become one of the most persistent pest insects in urban environment. Sometimes, even the most experienced pest control companies may need few to several treatments with insecticides to achieve complete extermination. The professional-use-only insecticide spray treatment is the only method that ensures long-lasting poisoning effect after the treatment, although it requires 2-3 weeks waiting period after the process. Treatments with hot air or dry steam work instantly on all life stages of the bed bugs, but at the same time there is no post-treatment effect. In combination, the spray and the heat methods achieve the highest success rates of bed bug extermination, affecting all life stages of the pest.


Due to the bed bug evolution in the mid 20th century, bed bugs have developed various physiological defense mechanisms to resist the active ingredients used in insecticides. Since then, bed bugs have improved and become more resilient, as some adult species persist the insecticide treatments. This is also proven by the fact that commercial bed bug sprays and smoke bombs spread the bed bugs throughout the property, in nearly all cases. Additionally, bed bug eggs, are naturally resistant to chemical treatments.

Hot air heat treatments for residents and businesses

There have been many reports of resistant bed bug populations across London and the UK that sometimes requires other methods to be used with our bed bug eradication programmes. Such methods include heat treatment with hot air, as well as targeted heat with dry steam. Our dedicated bed bugs control company provides bespoke heat treatments with hot air for commercial customers and residential bed bug infestations, achieving high success rates of bed bug extermination and control. The heat treatments we provide for residents in London could be set up even in single rooms, as well as the whole property.

For businesses in the hospitality industry, such as hotels, hostels, motels, service apartments, bed and breakfasts, care homes, leisure centres, Airbnb apartments, even cruise ship cabins we offer exclusive discounts and flexible terms. For inspections of more than 30 rooms at a time, we provide bed bug sniffing dog inspections that are able to achieve 3 times faster bed bug detection rate, as opposed to a single pest technician. After the initial inspection and risk assessment we carry out the treatment in all infested premises, without missing a spot. For best results we may apply a residual spray after the completion of the heat treatment.

Bed bug hot air heat treatment, as well as our residual spray treatments with professional insecticide, work perfectly well with many pest insects, such as carpet beetles, cockroaches, fleas, flies, textile and food moths, mites and others.

The process

The hot air heat treatment requires heavy equipment to be used and usually 7-8 hours for the whole process to complete. Initially, pest technicians carry out an inspection and risk assessment before undertaking the treatment. Certain temperature has to be maintained in the different areas of the premises treated that may vary between 47 and 60 degrees Celsius, depending on the building’s fabrics and heat penetration probability. During the process we monitor the temperature on digital screens, making sure that the heat will reach even the smallest cracks and crevices, exterminating all life stages of the bed bugs. There is almost no risk of damaging electrical appliances and equipment or any other belongings. The treated premises for bed bugs are safe to get back to just a couple of minutes after the treatment. In some cases, in order to achieve even higher efficiency and long-lasting effect after the heat, we apply professional-use-only insecticide through residual spray. This may require 3-4 hours waiting time after the process, before the property is safe for people and pets.
