PAPP-based lethal trap device (LTD)


This project aims to refine a lethal trap device prototype that can be fitted to all approved leg hold trap models and deliver an effective lethal dose of a humane toxin/anaesthetic.

This project builds on the research and development of the lethal trap device achieved through Invasive Animals CRC funding from 2005-2012.


In progress


  • Complete the development of lethal trap devices with scientific evidence from field trials that demonstrate the efficacy and establish operator exposure risks for the improved formulation of LTDs.
  • Prepare and submit an application for approval by the APVMA

Feb 2019:

An application was lodged with the APVMA on the 20th December 2018 for the registration of PAPPPutty, a PAPP based paste formulation that is applied to cloth wraps on traps jaws. This takes advantage of the wild canids response of biting the trap when captured and results in self-euthanasia of the captured canid.  

We are not proceeding with the registration of the BiteMe elastopmer reservoir that attaches to the trap jaw. Indications from the manufacturer are that the product, while effective, is not commercially viable and as a result, further research into that product has ceased.
