resetting toxin delivery system

A novel device for controlling brushtail possums (Trichosurus vulpecula)

Pen and small-scale field trials have been completed on a new, long-life, resetting toxin delivery system for brushtail possums (Trichosurus vulpecula). Devices are designed to attract and control possums over long periods of time with minimal input and maintenance. The units are species-specific, lightweight, environmentally robust, and have the ability to control 100 possums before requiring servicing. Devices dispense a measured dose (0.8 g) of a palatable gel containing 12.5% zinc phosphide (Zn3P2) onto a possum’s abdomen.
