Critical to OSPRI’s work towards eradicating bovine tuberculosis (TB) from New Zealand is the need to reduce possum numbers and keep them low over an extended period of time. A range of control methods are used to accomplish this including traps (kill-traps and live-traps) and toxic baits.
Introduced predators don’t belong here – but it is important to remove them in a humane way that avoids or minimises pain, suffering and distress – both to target and non-target animals.
All the traps we recommend have passed the National Animal Welfare Advisory Committee (NAWAC) guidelines which means they kill humanely and are easy to use and maintain.
The Possum Control Cost Calculator is an online publicly-accessible spreadsheet, containing mathematical formulae that can estimate the monetary costs of possum population control operations. It has been designed as a working tool to assist wildlife pest managers in planning operations, however it is also used by researchers, ecoepidemiological modellers, and as a teaching aid. It is free for use.
The following information relates to the welfare performance of traps used in New Zealand for capturing and/or killing small to medium-sized mammals. The tests relate to the welfare performance of the traps, NOT to their capture efficiency, safety, costs, or target specificity.
This document provides detailed information about eradication design, planning and methods that should be applied to operational planning for eradicating mice using aerial broadcast of poison baits.
This Protocol outlines a method for estimating indices of relative abundance of possum populations. It is based on sampling populations using various detection devices (Traps, Waxtags or Chewcards).

Covers the legal requirements of warning signs: - wording, design, installation, maintenance and recovery. A useful resource for agency staff and contractors implementing control programmes in the field.
A guideline on the minimum requirements for tracking vertebrate toxic agents. In two parts: (i) purpose and regulatory aspects, and (ii) standard forms with explanations for use, examples and key points associated with the tracking guidelines. For field staff and contractors responsible for vertebrate pest control programmes and pest managers responsible for ensuring that toxin tracking meets minimum standards.
