GRDC is committed to exploring options for better mouse management for Australian grain growers, and supports ongoing mouse-related research, development and extension (RD&E) initiatives.
Due to the increasing prevalence of mice in many key grain-growing regions, GRDC has partnered with CSIRO to enhance understanding of mouse management. As part of our RD&E initiatives, we have current investments on mouse management valued at over $7.5 million.
The CSIRO-led research focuses on:
- understanding mouse ecology, biology and management
- increasing surveillance
- investigating mouse feeding preferences.

30 Jul 2021, WA growers urged to check crops for mouse damage
Western Australian grain growers are being urged to ‘walk through paddocks’ to check for mouse activity and crop damage to determine whether they need to start baiting programs this season.
11 May 2021, Research prompts increase to recommended mouse bait rates
A new research investment led by CSIRO has enabled evidence-based increases to zinc phosphide (ZnP) mouse baits to help grain growers battling growing mouse numbers.
26 Mar 2021, Residual food reduction needed so mice take the bait
Residual food, the grain left in paddocks after harvest, is a becoming a problem because it provides a plentiful source of food for mice, reducing the likelihood that they will consume a lethal dose of bait.
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).
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.
