The DOC trap was designed by the New Zealand Department Of Conservation (DOC) for trapping non native species such as possums.

The traps are available in the UK but have to be purchased with, and fitted into the trap box. The DOC 100 is ideal for smaller ground predators like stoats, squirrels and rats. The larger DOC 250 is big and powerful enough for controlling Mink. The main advantage the DOC 25O has over a conventional cage trap, when use for mink control, is that the mink is always dead and there is no need for the operator to carry an airgun or pistol for humane despatch.
