Mouse management
Mouse management is a concern in many grain-growing regions. GRDC partners with CSIRO and others to enhance understanding of mouse management.
The CSIRO-led research focuses on understanding and management practices for:
- mouse ecology, biology and population dynamics for better management
- mouse surveillance
- mouse feeding preferences.
Since 2018, GRDC has invested over $8 million in mouse management RD&E.

Control now a year-round activity
Until recently, explosions in mouse populations in grain-growing areas were often followed by population crashes and consecutive years of little activity and damage. However, mice now appear to have become a more persistent problem with base populations carrying over from one year to the next.

Know your mouse numbers
Growers should monitor paddocks to get an accurate idea of their mouse problem as numbers can vary significantly within a district. Monitor by walking a transect of 100 metres across the crop and counting active holes in a 1-metre-wide strip (gives an area assessed of 100 square metres).

Baiting
Mouse baiting should be conducted as soon as practical after seeding to maximise efficacy and minimise crop damage. There are a number of different approaches growers can take when it comes to spreading mouse bait, depending on the equipment they have.
