THE GUARDIAN | Mouse plague hits WA grain farmers as numbers surge in SA

rain producers in Western Australia are dealing with mouse numbers well into plague levels, with activity also building across parts of South Australia.

Reporting from The Guardian highlights densities of up to 3,000–4,000 burrows per hectare in parts of WA, far exceeding the 800 mice per hectare threshold considered a plague.

Grain Producers Australia RD&E spokesperson Andrew Weidemann said the scale and spread of activity is creating significant pressure heading into seeding.

“Growers are dealing with sustained mouse activity at a time when timing is critical, and control options need to be effective,” Mr Weidemann said.

The report also points to rising concern in South Australia, with high numbers already being observed on the Adelaide Plains and Yorke Peninsula, increasing the risk of early crop damage.
