A plague of mice is current causing havoc in rural New South Wales Australia.
It is believed to be the worst plague of mice in decades and comes after a bumper grain harvest.
At this stage the issue is mainly within the rural area, however, the mice are getting closer to central Sydney.
Supermarkets are having to seal food in special containers and at least three patients in the local hospital have been bitten by the mice.
Experts that are trying to deal with the problem have been unable to stop the mice. Local media reported that just one pair of mice can produce on average up to 500 offspring in a season.
Intensive baiting programmes have so far had little success.
