Biogents’ patented capture method mimics the human being
All of the Biogents suction traps such as BG-Mosquitaire, BG-Home for homeowners and the BG-Sentinel and BG-Pro for professionals 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. This air stream mimics the typical convection currents 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.
Carbon dioxide from an artificial nose is added to the air stream in order to increase the spectrum of the mosquitoes captured, and maximize the capture rate. The emission rate corresponds to that of a toddler or an infant.
For the indoor trap “BG-Home”, additional features are included: a heated surface that attracts mosquitoes, UV light that attracts other flying insects and the complete dark appearance of the BG-Home which is also attractive for mosquitoes.
This unique trapping system was developed at the University of Regensburg in over 16 years of research. The traps have been used in over 400 research papers by scientists and other experts throughout the world.
