To ensure Fenn Traps are effective, they must be positioned so that target animals pass between the traps jaws rather than across the ends of the jaws. It is therefore a legal requirement within the UK that when Fenn Traps are set they must be placed inside an appropriate size natural or artificial tunnel or a purpose made container such as the Elgeeco Fenn Cage.
