Why Heat Treatment Is Effective Against Bed Bugs
- Targets bed bugs at every life stage: Heat treatment targets adults, nymphs and eggs in a single treatment process.
- Reaches where bed bugs hide: Heat penetrates furniture, mattresses, cracks and other difficult-to-reach hiding places.
- Treats more than the visible infestation: The entire treatment area is heated and monitored, rather than only treating where bed bugs have been found.
- Helps you keep your furniture: In most cases, beds, sofas and other furniture can remain in the property and be treated rather than discarded.
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
Furniture can often be retained and often complete eradication in just one visit.
Low Chemical Usage
Heat is the main treatment, with limited targeted products where appropriate
How Bed Bug Heat Treatment Works
Professional bed bug heat treatment uses specialist equipment to raise the temperature of the treatment area to levels lethal to bed bugs and their eggs.
Heat is circulated throughout the space, reaching furniture, mattresses, cracks and other areas where bed bugs hide. Temperatures are monitored throughout the treatment to ensure the required heat reaches key areas and is maintained for sufficient time.
Bed Bug Heat Treatment Process
1. Consultation & Quote
Tell us what you’ve found and which areas are affected. We’ll assess your situation and provide a free estimate, with an inspection arranged where required.
2. Preparing for Treatment
Before your appointment, we’ll provide clear preparation instructions covering access, belongings and any heat-sensitive items.
3. Heat Treatment
Our technicians set up specialist heating equipment, fans and temperature sensors throughout the treatment area. The property is then brought to the required temperatures while people and pets remain safely outside.
4. Temperature Monitoring
We monitor temperatures throughout the treatment, making adjustments where needed to ensure heat reaches key areas where bed bugs may be hiding.
5. Aftercare
Once treatment is complete, we’ll advise when you can re-enter and provide guidance on cleaning, monitoring and what to look out for afterwards.
Why Choose Heat Treatment?
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 all life stages.

Frequently Asked Questions
Do you need to prepare anything for a bed bug heat treatment?
Yes. Before the appointment, we provide instructions covering access, heat-sensitive belongings and any laundry or other preparation needed. Follow the guidance for your booking, as requirements vary with the property and treatment plan. If a preparation step cannot be completed, tell us in advance so we can discuss it. Your technician will check the agreed areas before work begins.
Read our heat-treatment preparation guide for more detail.
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. Read our guide on how long bed bug heat treatment takes.
How much does bed bug heat treatment cost?
Bed bug heat treatments start from £895. The final quote depends on the property size and layout, the agreed treatment areas and the work required. We provide an itemised quote after assessment. Guarantee eligibility and any follow-up treatment depend on the service scope and terms.
Why Choose Heat Treatment Over Chemicals?
Heat treatment can target all life stages while reducing reliance on widespread insecticide application.
Controlled heat can affect adults, nymphs and eggs when suitable temperature and exposure time are achieved. Chemical-only programmes depend on product performance, application and follow-up visits. The most appropriate approach depends on the property and infestation.
Our service is heat-led, with limited targeted products or diatomaceous earth used where appropriate as part of the IPM plan. People and pets must leave the treatment area, and the technician will confirm when re-entry is appropriate.
Are the results from a heat treatment immediate?
Heat acts during the treatment when bed bugs and eggs receive sufficient temperature and exposure time. A single room-temperature reading does not confirm success throughout the property. Follow our aftercare and monitoring guidance, and report evidence of renewed live activity so we can assess it under the applicable service terms.
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?
In many residential cases, yes, once the property has cooled and the technician confirms that re-entry is appropriate. Our service may include limited targeted products alongside heat, so follow the cleaning and re-entry instructions for your treatment.
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
