Why Heat Treatment Is the Most Effective Bed Bug Solution
High heat is one of the most efficient ways to treat bed bugs. Unlike traditional chemical-heavy treatments, our heat-led approach uses significantly less pesticide — making it safer for your family, guests, and the environment.
The thermal process is designed to penetrate deep into furniture, mattresses, and walls, reaching every potential hiding spot where bed bugs and their eggs reside. This comprehensive coverage ensures the complete eradication of the infestation in a single, targeted application.
Kills All Life Stages
High heat is able to penetrate deep into furnishings eliminating bed bugs.
Fast Results
A single treatment can often resolve your entire infestation in a single day.
Minimal Disruption
No need to dispose of infested furniture or wait for long periods before re-entering the area.
Low Chemical Usage
Our process uses low level pesticides and is safe for your home, family, and pets.
How Bed Bug Heat Treatment Works
During heat treatment, we use specialist high-powered indirect-fired heaters to safely and effectively raise a room’s temperature to between 49°C and 60°C, maintaining this lethal range for a sustained period.
These industrial-grade heaters are calibrated to reach the exact temperatures needed to eliminate bed bugs at every stage of their life cycle, including eggs, which are often resistant to chemical treatments.
Heat treatment works by breaking down the essential proteins and enzymes that bed bugs rely on to live. This effective method targets the pest at a biological level, making it highly effective for complete eradication. Unlike chemical treatments, which often fail to reach deep hiding spots, heat penetrates every crack and crevice — leaving bed bugs with nowhere to escape.
Bed Bug Heat Treatment Process

We assess the bed bug infestation and provide a free estimate, either remotely or through a property inspection if required.
2. Preparation Advice
Before the visit, we send simple preparation guidance to help optimise the heat treatment, such as removing heat-sensitive items.
3. Heat Treatment Day
Our technicians install industrial heaters and sensors, raising temperatures to 50–60°C to eliminate bed bugs at every life stage.
4. Monitoring and Validation
Temperatures are monitored in real time to ensure lethal heat levels reach all hidden harbourage areas.

After treatment, we provide advice to help prevent reinfestation. Qualifying services include our 60-day warranty for added reassurance.
Why Choose Heat Treatment Over Chemicals
When it comes to pest control, heat treatment outperforms traditional chemical methods in both effectiveness and safety. Unlike sprays that may require multiple visits and still struggle to eliminate eggs, heat penetrates deep into mattresses, furniture, and walls, destroying every life stage of pests in a single session.

Frequently Asked Questions
Do you need to prepare anything for a bed bug heat treatment?
Yes, but it’s a relatively straightforward process, and we will guide you every step of the way. Before our bed bug specialists arrive at your property to carry out the service, you will be provided with a simple preparation form that will outline exactly what needs to be done.
It will go over which items need to be removed, how to declutter key areas, and which personal items (like clothing or bedding) may need to be washed on a hot cycle before or after the treatment. There’s no need to overhaul your entire space – you just need to take care of a few easy tasks to make sure the heat treatment process can be carried out safely and effectively.
For added peace of mind, during the initial inspection of your property, we will still double-check everything to make sure that we can safely carry out the treatment. By having our customers take care of the basic preparation of their property, we can ensure that the treatment runs efficiently and without any unnecessary delays.
How long do bed bug heat treatments take?
Most bed bug heat treatments are completed within 4 to 8 hours, depending on the size of the property and the severity of the infestation. You’ll be back to normal before you know it.
Larger homes may require more than one day for successful treatment, and commercial properties will vary based on the number of rooms or areas that need treating. Check our our guide on how long does bed bug heat treatments take.
How much does bed bug heat treatment cost?
The final cost depends on factors like the property size, the number of rooms being treated, and the severity of the infestation. Full-property treatments start from £795
While the initial cost can be higher than a single chemical spray, our heat treatment is a single-visit solution that eradicates the entire infestation, including all eggs. This makes it far more cost-effective long-term than multiple chemical treatments that often fail. We provide a firm, itemised quote after a quick assessment.
Why Choose Heat Treatment Over Chemicals?
Heat treatment is a superior solution for two main reasons: effectiveness and safety.
Unlike chemical sprays, which often require multiple visits and struggle to kill pesticide-resistant eggs, a single heat treatment eradicates all life stages in one day. The heat penetrates deep into mattresses, furniture, and wall voids, destroying the entire infestation—including the eggs—which is critical for preventing a recurrence.
Furthermore, our heat process is an environmentally-friendly, chemical-free solution. It leaves no toxic residues behind, making your home or business immediately safe for children, pets, and guests. This also completely bypasses the common problem of bed bug resistance to traditional pesticides.
Are the results from a heat treatment immediate?
Yes, the results from a standard bed bug treatment with heat are immediate. Once the treated area gets to a temperature of between 49°C and 60°C, within the space of several hours, all bed bugs, including their eggs, will be eliminated.
Do I need to leave my property during the treatment?
Yes, you will need to leave your property during the heat bed bug treatment. This includes any pets that you might have. Once the treatment is over and your property has cooled down to a safe temperature, our team will let you know, so you can head back inside.
Can I sleep in the treated room the same night?
How do bed bugs spread between properties?
Bed bugs spread in a couple of very predictable ways, the most common of which include:
- Visitors who may unknowingly carry bed bugs in clothing, bags, or personal belongings
- Travel, particularly through luggage after staying in infested hotels or rentals
- Adjoining properties (bed bugs can travel through cracks, pipework, and sockets)
- Second-hand furniture, such as mattresses, sofas, and bed frames
How can I prevent bed bugs from coming back?
To prevent bed bugs from coming back, it is important that you follow a few simple but important steps. They include:
- Wash and heat-dry all your clothes after every trip
- Inspect your luggage carefully after a trip before you put it away
- Avoid or very carefully inspect second-hand furniture before you bring it indoors
- Use mattress encasements designed for bed bugs to protect key hiding areas
- Reduce the amount of clutter in your property to limit potential hiding spots
- Vacuum your property regularly, especially around beds and skirting boards
