Farmers Battle Epic Mouse Infestation Across Australia

Large numbers of mice are infesting multiple regions across Australia, forcing farmers to take drastic actions such as shooting the pests and burning damaged crops. Visual evidence from social media depicts enormous swarms engulfing farmlands in Western and Southern Australia, with some reports showing roads and grain silos covered in rodents.

Scientists have declared the situation a plague, with populations reaching up to 4,000 mice per hectare in Western Australia, far exceeding the threshold for a plague. This crisis is particularly concerning given that farmers are already contending with challenging weather and fuel costs. The recent heavy rains and floods in South Australia, followed by warmer weather and increased crop yields, created ideal breeding conditions for mice.

The escalating mouse numbers pose a substantial threat to Australia's $3 billion grain export industry and have broader economic implications for small businesses and supermarkets. An emergency request has been submitted to the Australian Pesticides and Veterinary Medicines Authority (APVMA) to increase the concentration of poison in baits, aiming for a lethal dose with every grain. This situation mirrors a severe mouse plague from 2020-2021, which resulted in approximately $1 billion in damages.
