This project developed a Lethal Trap Device (LTD) 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 PAPPutty™.

This project built on the research and development of an LTD initiated by Victorian researchers and continued by NSW DPI through Invasive Animals CRC funding from 2005-2018.

Key achievements


  • Completed the development of LTDs with scientific evidence from field trials that demonstrate the efficacy and establish operator exposure risks for their improved formulation.
  • Prepared and submitted an application for approval by the APVMA, the application was lodged with the APVMA on 20 December 2018 for the registration of PAPPutty™, a PAPP-based paste formulation that is applied to cloth wraps on a trap jaw. This takes advantage of the wild canids’ response of biting the trap when captured and results in self-euthanasia of the canid.


  • PAPPutty™ is now registered with the APVMA.

This project was led by NSW DPI in collaboration with Connovation and supported by funding from the Australian Government Department of Agriculture, Fisheries and Forestry.

Project updates

August 2020

The APVMA advised that the application for the registration of PAPPutty™ has been fully assessed and was passed for delegate approval. The registration application for PAPPutty™ was subsequently granted by the APVMA on 28 September 2020 and arrangements are underway to distribute them nationally through Animal Control Technologies Australia (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.
