Huge numbers of mice are threatening crops in eastern Australia. In New South Wales state, officials have described the situation as a “plague” that has never been seen before. The small animals have spread over wide areas of agricultural land across New South Wales and parts of the neighboring states of Queensland and Victoria. In addition to eating grain crops, the mice have damaged farm and household equipment, caused power outages and invaded supermarkets. Adam Marshall is the Agriculture Minister for New South Wales. He recently said the situation had reached “a critical point” and needed to be dealt with immediately to prevent further problems. “If we don’t significantly reduce the number of mice that are in plague proportions by spring, we are facing an absolute economic and social crisis,” Marshall said. Bruce Barnes runs a family farm near the town of Bogan Gate in central New South Wales. He told The Associated Press he was taking a risk by planting crops. “We just sow and hope,” he told The Associated Press. The word sow describes the process of planting seeds. The state’s main agricultural organization predicts the mice could cause $775 million in losses. The state government has ordered 5,000 liters of the banned poison Bromadiolone from India. But the federal government has not yet approved the substance for emergency use around crops. Critics fear the poison will kill not only mice, but also many other animals that feed on them, or family pets. Marshall said the state wants to use the Bromadiolone “because we need something that is super strength.” Farmers like Barnes had struggled during four years of extreme dry conditions before 2020 finally brought a good rainy season. The wet weather helped produce Australia's largest-ever grain crop, but also provided more food for the mice.
