Bed Bug Heat Treatment in Hertfordshire
Bed bugs are one of the most difficult household pests to eliminate. They hide deep within beds, mattresses, furniture, skirting boards and cracks in walls, making them extremely difficult to control with DIY products alone. If left untreated, a small infestation can quickly spread throughout a property.
At Summit Pest Control, we provide professional bed bug heat treatments across Hertfordshire, including St Albans, Hemel Hempstead, Watford, Hatfield and the surrounding areas. Using specialist equipment, we can eliminate both live bed bugs and their eggs with an environmentally friendly treatment that avoids many of the problems associated with traditional insecticides.

Why choose heat treatment for bed bugs?
Over the years, bed bugs have developed increasing resistance to many commonly used insecticides. While chemical treatments still have an important role in certain situations, heat treatment has become one of the most effective methods of achieving rapid control.
Our professional heat treatment works by raising the temperature within the affected room to a level that bed bugs simply cannot survive.
Benefits of heat treatment
- Kills both live bed bugs and their eggs.
- Highly effective against insecticide-resistant bed bugs.
- Chemical-free treatment option.
- Reaches deep into cracks, furniture and mattresses.
- Environmentally responsible solution.
- Reduces the need for repeated chemical applications.
How does professional bed bug heat treatment work?
Our experienced technicians attend your property with a fully PAT-tested professional heat treatment system.
Each confirmed infested room is carefully prepared before specialist heaters are positioned to safely raise the room temperature.
The room is heated and maintained at approximately 55°C for up to 2 hours. Research has shown that 54.4°C is the critical temperature required to effectively dehydrate and destroy both live bed bugs and their eggs.
This controlled heating process penetrates areas that traditional sprays often struggle to reach, providing a highly effective treatment throughout the room.
Frequently Asked Questions
Why not just use insecticide sprays?
Many over-the-counter insecticides only kill insects that come into direct contact with the spray.
Bed bugs hide extremely well and many populations have developed resistance to commonly available insecticides.
Professional heat treatment targets the entire room rather than only visible insects, making it one of the most reliable treatment methods available.
How do I know if I have bed bugs?
Common signs include:
- Small itchy bites that often appear overnight.
- Tiny blood spots on bedding.
- Black spotting (bed bug droppings) around mattresses.
- Live insects hiding in mattress seams or bed frames.
- Cast skins left behind as bed bugs grow.
- Sweet, musty odours in heavy infestations.
If you suspect bed bugs, avoid moving infested furniture between rooms as this can spread the infestation.
Can I get rid of bed bugs myself?
DIY treatments rarely eliminate an established infestation.
Using supermarket sprays or household insecticides often drives bed bugs deeper into hiding without solving the problem.
Professional inspection and treatment usually saves both time and money by dealing with the infestation properly from the outset.
How to prepare for your bed bug heat treatment
Proper preparation is essential for the treatment to be as effective as possible.
Please complete the following before our visit:
- Wash all bed linen at 60°C.
- Avoid attempting to treat the infestation yourself using domestic insecticides.
- Vacuum the affected rooms thoroughly and dispose of the vacuum bag immediately afterwards.
- Remove all pets from the treatment area.
- Remove all houseplants.
- Move furniture and belongings at least 8 inches (20cm) away from walls where possible.
- Turn your home’s heating up to 25°C on the morning of treatment.
Our technician will explain any additional preparation required for your particular property.
