We have carried out destructive tests, this to explore the relation between the size of the ball (the pressure of the ball) and its strength at given temperatures. We have used an ambient temperature outside the funnel of 35 degrees Celsius as measuring level. At this tempature the inflation of the ball will give problems. […]

The principle is only attractive to those insects that are attracted by infrared temperature (most flying insects can see ultraviolet light, not infrared light) These insects, typically blood sucking insects, will be attracted by the H-trap.

The H-trap is weather proof and storm proof. Needless to say that it will not withstand extreme weather and wind conditions, such as a hurricane.

When the H-trap is used to control horse flies nearby horses we recommend to place one H-trap with a maximum of 5 horses. Horse flies cannot see the difference between the H-trap and a horse. With a maximum of 5 horses we still have multiple chances a week to get the horse flies in the […]

Pending on temperature the horse flies will come out of the ground from Early spring (European situation: from April onwards) The female horse flies will than immediately start looking for blood, this to fertilize the next batch of eggs. It is important that we have the H-trap in position before this starts happening. This way […]
