The new trap system, called the H-trap, effectively controls the amount of horse flies and reduces them to an absolute minimum. The H-trap needs to be placed outdoor and works without the need of chemicals or electricity. Extensive tests have shown that reductions of 90-95% on horse flies in an area around the trap can be realized.

The horse flies will mistakenly see the centrally placed ball in the H-trap as a large animal and move towards this ball. Once they are positioned on this black ball of the H-trap they will investigate the “victim” and try to sting it. After this unsuccessful attempt, they will fly away from the trap. Horse flies are vertical risers, they can only fly upwards. The trap is designed in such a way that via a conical hood system, the flies are guided upwards into a centrally placed collect bin. From this bin they cannot escape. The bin needs to be emptied periodically. Innovative and functional.
