Farmers work together to predict mouse plagues.


Current advice: Keep an eye out for mice during crop sowing and growing season.

Grain growers are being encouraged to keep a close eye on mouse activity over the coming crop growing and harvesting season and regularly record their observations via MouseAlert.
MouseAlert aims at improving early warning of possible plagues to enable a rapid response to increases in mouse activity.
MouseAlert can be used to map where mice are and where they aren’t, so participants can play a vital role in developing a better picture of mice distribution and numbers.
MouseAlert can be used as often as you want – for recording mouse activity, or viewing what is happening in your local area.
Please take 3 minutes to complete a MouseAlert report. Your data will help to identify the risk of mouse plagues in your region in future growing seasons.

Update: High populations in Victoria, moderate elsewhere. 

High populations of mice in Mallee and Wimmera, Victoria – Numbers are high for this time of year. Mice are causing some damage to growing crops but baiting appears to be effective. Moderate populations of mice in Yorke and Eyre Peninsulas, South Australian Mallee and Southern NSW - Mice are causing some damage to growing crops, including  cereals, canola and pulses, but baiting has generally been effective. Mouse abundance remains low in all other regionsGrowers should actively monitor mouse activity and look for signs of mouse damage (chewed tillers; nodes and pods in canola and pulses). If mouse population high: Consider application of bait now (beware of 2 week withholding period). If mouse population low-moderate: Continue to be vigilant (watching brief). Communicate with your local bait supplier to understand supply time-frames and help decide if you need to pre-purchase bait. Crops can’t be treated with bait within 14 days of harvesting beginning (withholding period). Please record observations of mouse activity in MouseAlert.

Simply download this App, and start recording mouse activity in your local area. MouseAlert is part of the FeralScan Phone App.

When to record mouse activity

Recording mouse activity at key times will improve forecasts that will help early application of control to reduce the impacts of plagues. Information is particularly valuable at 3 key times in the cropping cycle.

Bring your farming group online

MouseAlert can be used by landholder groups to inform members of current trends in mouse activity and damage. By joining a group, you can (1) keep members up-to-date about current issues, (2) alert members to changes in mouse activity, and (3) work together to control mice before their numbers rise.

Respond early to prevent mouse problems

Mice can cause enormous damage to crops in a very short time period. Most damage occurs during mouse plagues, however by the time a large plague is obvious, it is generally too late to do anything to stop the damage. That is why acting early (and actively recording mouse activity at key times) is very important.
