First it was a few, then a few hundred and now communities in the Orana region are swamped with mice.
As farmers harvested a bumper crop late last year after three years of drought, delivering what GrainCorp said was record receivals, the rodents emerged.
They made their presence known at farms, and then they were spotted in towns in the region and at Dubbo.
By March, CSIRO mouse researcher Steve Henry said: "Certainly there are areas of northern NSW that you would have to say is a full-blown plague. Armatree north, basically."
Mice start to breed when they're about six weeks old, and then they can have a litter every 19 to 21 days after that, Mr Henry says.
"...they say a single pair of mice can give rise to 500 offspring in a season, basically," Mr Henry said.
