The DoC 150 is an innovative humane kill spring trap developed by the Department of Conservation in New Zealand. They were developed to assist conservationists with the protection of native species from introduced predators. These traps pass National Animal Welfare Advisory Committee (NAWAC) guidelines in New Zealand (using internationally recognised criteria) for effective kill trap performance. In the UK, the DoC 150 must be set within an artificial tunnel constructed to the design specified by the Department of Conservation and are approved for use in trapping grey squirrels, rats, stoats and weasels. PERDIX DoC 150 spring trap tunnels are available to purchase in a flat pack kit.
