Millions of mice are causing a lot of damage in Australia. The country has its worst mouse plague in decades because of a big wheat harvest last year. The mice are a big headache for farmers. The animals have caused problems for a prison west of Sydney. It has moved 200 staff and 420 prisoners to other jails in the area because of health and safety reasons. It will take 10 days to clean the prison and repair electric cables.
Mice have damaged many buildings. Their droppings are a health hazard. In addition, they have damaged electrical wires. This is a danger to buildings and humans. A prisons spokesperson said: "The health, safety and wellbeing of staff and inmates is our number one priority, so it's important for us to...carry out the vital repair work....We need to...ensure the site is thoroughly cleaned and...repaired." He will look at ways to stop future plagues.
