Mouse infestation advice

This year, Australia’s wet weather conditions have resulted in increased availability of food sources for mice. The increase in food leads to a risk of rapid growth of mouse populations and mouse infestation on farms.

Since March 2021, Central-West New South Wales (NSW) has been experiencing a significant mouse infestation event. Western Australia has also reported much higher increases in mouse numbers this winter. While mouse numbers elsewhere in Australia are still relatively low due to cooler winter conditions, numbers are still higher than this time last year.

If you are in an area affected by increased numbers of mice, you are encouraged to act quickly. Late winter to early spring is the best time to start, before populations grow rapidly in the warmer months.
