The MT-trap is designed to catch those aggressive insects, which commonly create a lot of irritation: Horse flies and/or Wasps.
The principle used for attraction of Horse flies is a proven and widely accepted method: With help of the sun, we heat up the air under the funnel, which is absorbed by the black ball. The ball itself will start emitting this infrared energy. Horse flies are attracted by infrared radiation, coming from larger objects.
They see these objects as potential feeding sources (humans or larger mammals, such as horses or cows) and will land on these. Once they are positioned on the black ball, they will investigate it and try to sting it. Since they will be unsuccessful in gaining their desired
blood feed, they will follow their natural behavior and fly away. Horse flies naturally
fly upwards. Around the ball we have placed a funnel system, where they are guided into
a centrally placed collect tray, from which escaping is not possible.
Wasps have the same fly behavior as horse flies; also they naturally fly upwards.
Unlike horse flies, wasps are not attracted by infrared objects, but by sweet scents,
such as a sugar concentrations. An optional wasp fluid, placed in the collect bin,
will lure wasps. Wasps will enter the trap from below and fly into the collect bin.
From here escaping is simply not an option for them.
