If they get into our property they can cause serious damage. They chew woodwork and ceilings, strip the insulation from electrical wiring, tear up fibreglass insulation to form nests and sometimes drown in cold water tanks.
The noise they make, particularly at night, scratching and running about can be very disturbing.
They cause environmental damage, stripping bark off trees, causing young trees to die, eat strawberries, apples and plums and can destroy many garden plants with their activities.
