As the CSIRO warns that Australia's mice plague could last for two years, this map shows how the rodent infestations have increased across south-east Australia in 2021. The Woodstock farmer said his inventive mouse trap was an “old trick” he used to fight the mice plague in 1984, when he was just 12 years old. He likened the disaster to the mice plague of 1984 where he was forced to walk around his farm wearing rubber bands at the bottom of his jeans to stop mice from crawling up his legs. While NSW has seen the most rodents, Queensland, Victoria and South Australia have also been affected by the scourge. The mice plague started in spring last year during the harvest season, caused by a combination of ideal weather conditions for breeding and a bountiful grain harvest.
