Australia is currently experiencing a severe mouse plague, particularly affecting Western Australia, where millions of mice have invaded homes and farms. The plague began after a record grain harvest, which provided ample food for the rodents, leading to rapid reproduction. Mice breed quickly, with females capable of producing up to 10 offspring every 20 days. Reports indicate mouse populations in some areas exceed 8,000 mice per hectare, resulting in significant damage to crops and property. Farmers are struggling with the standard bait, which has proven ineffective as many mice only consume one poisoned grain and do not die. In response, the Australian Pesticides and Veterinary Medicines Authority has issued an emergency permit allowing the use of a more potent bait that can kill with just one grain. This measure is expected to reduce mouse numbers quickly, although it cannot be used in urban areas. The infestation is causing severe economic impacts, with farmers needing to re-seed crops and businesses facing stock losses. Public health concerns have also been raised, prompting hygiene alerts as communities deal with the ongoing crisis.
