PAPP-based lethal trap device (LTD)


This project aimed to develop a lethal trap device that can be fitted to all approved leg hold traps, replacing Strychnine, to deliver an effective lethal dose of PAPP in the form of a PAPP Putty.

This project builds on the research and development of a lethal trap device initiated by Victorian researchers and continued by NSW DPI through Invasive Animals CRC funding from 2005-2018.


Completed. PAPPutty registered with the APVMA.

August 2020 update:

The APVMA advised that the application for the registration of PAPPPutty™ has now been fully assessed and was passed for delegate approval. The registration application for PAPPPutty™ was subsequently granted by the APVMA on the 28th September 2020 and arrangements are underway to distribute them nationaly through Animal Control Technologies Australai (ACTA).

The BiteMe™ product was not taken to full commercialisation stage as our commercialisation partner advised that it was not likely that the product would be commercially viable.

This project:

  • Completed 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.
  • Prepared and submitted an application for approval by the APVMA, the 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 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.
