Our Traps Mimick the human being.
The airflow is a Counter-flow-principle.
All of Biogents’ mosquito traps work according to the patented “counter-flow-principle”. The counter flow principle is an airflow system whereby air is being sucked into the center of the traps and being blown out via the top part of the traps. This airflow system was developed and researched over a period of sixteen years at the University of Regensburg in Germany.
Four elements create the characteristics of our traps: a small fan, color contrast, a scent dispenser and carbon-dioxide.
The Fan
A 4-Watt fan sucks the air into the center of the trap. At the bottom of the trap the air picks up an artificial human scent and then gets diverted upwards past the trap-walls and leaves the trap through the white perforated top. The air plume that leaves the trap now mimics the presence of a warm human body and therefore mosquitoes start to get attracted.
Color contrast
Mosquitoes are also attracted by the color black. The black trap entrance contrasts with the white mosquito trap top part and as such act as a visual cue for the mosquito.
The Scent Dispenser
The scent dispenser sits at the bottom of the mosquitotrap and, while the fan blows air over it, releases substances that resemble those found in our human skin. This way the air leaving the trap is enriched with a ‘human scent‘ which is a big attractant for mosquitoes.
Carbon-Dioxide
Carbon-dioxide is the main component that we human beings breath out and is a huge attractant to mosquitoes. The CO2 is added to the air plume through a nozzle that sits on top of the trap. Per 24 hours between 200 – 500gr of CO2 is released. An adult male exhales about 700gr per 24 hours.
When mosquitoes become aware of the artificial human scent and start to approach the traps, the inwards suction current will pull them into the center funnel and into a catch bag. Here the mosquitoes die of dehydration.
