Due to favourable crop growing conditions over the past year, food sources for mice are readily available. Access to food may result in a rapid growth of mouse populations and mouse infestations on farms. Be prepared to bait as you sow this year’s crops if mice are active in your paddocks.
Continue to monitor crops after sowing and if mice are still present. Late winter to early spring is the best time to start, before populations grow rapidly in the warmer months.
A small number of mice can turn into a large infestation within weeks. This is because mice start breeding at 6 weeks of age and produce a litter of up to 10 pups every 19-21 days.
Unlike any other animal, mice can become pregnant again within two to three days of giving birth, creating a constant reproduction cycle.
