Biogents’ patented capture method mimics the human being

All of the Biogents traps function according to the same patented counterflow principle:

A single fan sucks the attracted mosquitoes into a catch bag below the black suction column of the trap. The air stream is then diverted and exits the trap through the white upper surface made of plastic. This air stream mimics the typical scent plume that is produced by a warm human body. To the mosquitoes the trap looks just like a human being.

The contrast between the dark center and the light surface of the trap is an additional important attractive signal for the mosquitoes, and completes the capture method.

A scent dispenser inside the trap enriches the air stream with small amounts of substances similar to those also emanated by the human skin. These substances act as synergists to enhance the attractiveness of the traps. Used alone without the trap, e.g., incorporated on a sticky surface, they would be ineffective.

Carbon dioxide, in the form of dry ice or bottled gas, is added to the air stream in order to increase the variety of species collected, and maximize the capture rate. Typically, the level of CO2 released corresponds to the amount exhaled by a young child.

Scientific proof

This unique trapping system was developed at the University of Regensburg in over 16 years of research. Its efficacy has been confirmed in over 300 research papers by scientists and other experts throughout the world.

Biogents use a patented combination of attractive contrasts and air streams that are directed upwards. A mixture of human skin scents and carbon dioxide that is also patented increases the capture rate even further.
Biogents traps attract the mosquitoes in multiple ways: Through black and white contrasts which act as visual cues and through human body emissions.
