Control of rodent infestations

Project Leader: Prof Linton Staples, Animal Control Technologies Australia

Aim: To improve methods for monitoring and control of mice and rats

Project: 3.t.2

Project summary

The Animal Control Technologies Australia (ACTA) group is responsible for a key rodent research program within the IA CRC. In collaboration with Dr Luke Leung and his rodent team at the University of Queensland (Gatton) campus, they are seeking to improve methods for monitoring and control of mice and rats.

A second priority is to improve the management of rodents in intensive crops and for environmental management on islands. The replacement of large-scale misapplication of certain anticoagulant rodenticides is of great significance in protecting Australia’s native wildlife. The prevention of overwhelming infestations of rats and mice is also important in protecting fragile habitat and seed banks.

This works builds on ACTA’s previous success in managing rats in sugar cane crops and tree plantations in far north Queensland, and the control of plague mice in broadacre crops throughout Australia with MouseOff® and RattOff®.

The project aims to:

  • review all objective rodent monitoring systems against target situations
  • survey industry stakeholders (difficulties with rodents, research priorities, suitable trial and test sites)
  • source appropriate formulations and presentations of key active ingredients having regard to suitability, safety, regulatory framework, cost availability and humaneness (if appropriate)
  • apply selected rodenticides to intensive crop, industrial and island situations
  • obtain regulatory data that will support ACTA registration applications for technology specific to certain rodent infestation problems
  • develop advisory information to enable improved rodent management in industrial situations, intensive crops and on islands

With the possible exception of the development of paste or drink formulations, this project does not require development of new technology.

It is anticipated that most data from the project will be published or released in technical reports to the Australian Pesticides and Veterinary Medicines Authority and sponsoring industry groups.

Key achievements

  • Efficacy of rodenticide formulations for rodent control demonstrated in a variety of situations where no registered chemical control methods are currently available, or where improved techniques are required. This includes tree plantation and brassica cropping systems.
  • Results to date have been published in scientific journals and four relevant national and international conferences.
