This Kerbl gadfly trap TaonX can be used wherever gadflies are a nuisance: horse paddocks, riding arenas, cowsheds, golf courses, gardens and parks along lakes and river banks, etc. The TaonX functions as follows: the sun heats the black ball and thus simulates a target for blood-sucking for the gadfly. When the gadfly realises that the attempt is unsuccessful, the insect instinctively flies up and lands inevitably in the trap. This Kerbl gadfly trap TaonX reduces the gadfly presence in the immediate vicinity by up to 95%, and has a maximum effective range of approximately 10,000 m².
