The DoC 150 is an innovative humane kill spring trap developed by the Department of Conservation in New Zealand that is powerful but very easy and safe to use. In the UK, these traps must to be used in a specially designed tunnel to ensure a humane kill and also prevent non-target captures. The PERDIX DoC 150 trapping tunnel is designed to meet the requirements specified by the Department of Conservation. By purchasing both together here, the tunnel comes fully assembled with the DoC 150 spring trap correctly fitted and ready to use. Our tunnel is constructed from WBP treated plywood with a hinged lid to allow easy access to the trap for baiting or removal of animals and a hasp and staple latch to allow the tunnel to be locked if required (supplied with carbine hook). The DoC 150 trap and tunnel are approved for use in the UK for trapping grey squirrels, rats, stoats and weasels.
