This fly trap has been specifically designed for outdoor use. Flies are caught outside before they can enter indoor areas. Through its mechanical design, flies are attracted by the scent and enter the trap, but cannot escape due to the trap's structure. Even with a very high fly population, there is sufficient capacity for capture.

The trap reduces flies not only in the house or barn but also on the terrace and in the garden. It is therefore of interest to community gardens, beer gardens, guesthouses, and private homes in agricultural areas.

The XL 8-liter reusable model is cost-effective for the user. When the trap is full, a new refill pack is simply used, and the old bag along with its contents can be disposed of in an environmentally friendly manner. Approximately 3 to 4 bait packs are needed per season. There is no resistance development. The trap can also be emptied onto compost.
