Western Australia is currently grappling with a severe mouse plague, with population densities reaching up to 8,000 mice per hectare.
Environmental factors such as high rainfall fueled the initial outbreak, but drier conditions and summer heat are now expected to reduce rodent numbers.
Farmers have deployed higher-dose zinc phosphide bait to save crops, following approval from federal regulators in May.
There are growing concerns regarding the impact of these potent baits on native bird populations, with reports of fatalities in regions like Coorow.
