Outlook for Autumn and Winter 2020
CSIRO monitoring of mice activity indicates that mouse numbers are moderate to high in the North Adelaide Plains, and moderate in parts of the Mallee, Eyre and Yorke Peninsulas.
In these areas, mouse numbers are likely to cause some damage at sowing.
Mice numbers may have increased because of increased grain on the ground from wind and storm damage, particularly to 2019 barley crops.
Growers are advised to monitor mouse activity on their own farms and across multiple paddocks to gauge mouse numbers to inform their management decisions. Mouse chew cards or active burrow counts are useful ways to monitor activity at this time of year.
CSIRO provides further information on recent mouse activity across Australia ().
Various mouse control options include:
The reduction of food sources especially spilled grain and weeds, by livestock grazing, prickle chain, small disk chain, speed tilling,
rolling stubble to bury remaining food sources.
- The reduction of available shelter where mice can escape predators.
- Poison baiting 4-6 weeks before sowing, and at sowing, if high numbers persist.
Manage mice over large areas (1,000 ha) by coordinating with neighbours to reduce reinvasion by mice
- Monitoring for an increase in:
- mouse sightings
- the number of burrows
- crop damage
- birds of prey.
Detailed mice control techniques are available on the
- Mouse management fact sheet (GRDC website)
- PestSmart Connect website
- Mouse control in and around buildings fact sheet ()
When using poison baits it is a legal requirement under the Agricultural and Veterinary Products (Control of Use) Act 2002 to:
- use registered bait products
- follow label instructions
- not possess or use 'home-made' baits.
A number of registered bait products are available to control mice. Your local chemical retailer will be able to advise you on the right product for your situation.
