Controlling mice in NSW

NSW is currently experiencing high mouse numbers in cropping regions. Monitoring, detection and integrated management across farm are crucial for reducing the risk of mouse impacts. Reducing access to and covering food, together with baiting with zinc phosphide, can control local mice populations.

To assist landholders control mice, the Grains Research and Development Corporation (GRDC) and CSIRO have compiled the ‘Tips and Tactics: Better Mouse Management’ guide.This practical guide provides tips and advice on a range of issues, including:

  • integrated control advice - year-round, at sowing (autumn), during crop growth (winter) and prior to harvest (spring and summer)
  • baiting recommendations
  • monitoring techniques to understand local activity.

This guide can be downloaded here.

If landholders have concerns over the potential impact of mouse numbers on their livestock health, please contact your local district veterinarian.

Baiting mice with zinc phosphide

NSW Department of Primary Industries has successfully applied to the Australian Pesticides and Veterinary Medicines Authority (APVMA) to allow the use of zinc phosphide bait on bare fallows prior to the 2021 sowing period.

The permit allows for bait to be applied late in the afternoon to maximise consumption of bait by mice, which generally feed at night, and is in effect until August 2022.

The approval requires users of zinc phosphide to report any bird kill incident following application of the bait to fallow land to either NSW Department of Primary Industries or NSW Environment Protection Authority.

Producers should not harvest crops or allow livestock to graze baited areas for 14 days after application.

NSW Department of Primary Industries and Local Land Services have produced a factsheet on APVMA registered zinc phosphide products for mouse control in paddocks.
