1. Heat extermination without chemicals as a service:

Before any treatment, we undertake a detailed building and apartment inspection to precisely determine the scope of the pest infestation. For more precise localization of any bedbug infestation, we are currently working on the training of a bedbug finding dog.
With our chemical-free method, in principle we can fight all types of insects, because protein coagulation takes place in all forms of insects.
Avoid the use of insecticides in your living or working space. Our treatment method will not impair the environment in your living space!

2. Sales and trade with Thermo-bug® devices:

Our Thermo-bug® devices are designed to be extremely sturdy and are also suitable for long-term use.
We would be happy to provide you with a non-binding price quote.

We solve the problem differently.

The bloodsuckers
are back.

The Bedbug
lat.: Cimex lectularius

This bloodsucking ectoparasite attacks mammals, birds, and humans. Fully grown bedbugs have a length, when ungorged, of 4-7 mm and a yellow to reddish brown appearance. When gorged, they reach 9 mm in length; in such cases the abdomen becomes increasingly black. While the bedbug hides during the day, at night it goes out in search of a host to fund nourishment. At 18 - 22°C room temperature, the fully grown animal sucks every 3 - 7 days for 3 to 20 minutes each time.
At ideal temperatures and with sufficient nourishment, a bedbug has a lifespan of up to 18 months. A female lays up to 300 eggs at an average rate of 3 per day.

Hoteliers and private households are sounding the alarm!
Until only a few years ago, these insects were considered extinct, now they are here again: the bedbugs. Exterminators blame resistance to insecticides, increased global travel activity, and an increased sensitivity in society to the use of pesticides and insecticides. Once you have the little parasites in your house, it is not so easy to get rid of them again.
An unbearable itching, generally several bites in a row (the bedbug “street”), small spots of blood on the sheets, and a sweet-seeming smell in the room – these are sure signs of a bedbug infestation.


The strategy is: heat.

Biochemists call it denaturation. This concept refers to a structural change in organic molecules in substances such as proteins which involves the loss of the biological functions of these molecules. Every cell consists of proteins.
If the environmental temperature is therefore held for a long period (greater than one hour), all protein compounds coagulate permanently. All life dies off.

The temperature of the environment decides on life and death.

Above 45°C and below -18°C, every form of life dies off in the shortest time. With the Thermo-bug®, heating to a room temperature of up to 70°C is possible without any problem. Quick, quiet, and efficient without the use of chemical agents - and 100% deadly.
For full-coverage, thorough room air heating, we recommend the use of two Thermo-bug® devices. We recommend a temperature data logger for heat measurement and documentation.
Denaturation through thermal eradication.
