Zinc phosphide and bromadiolone: Frequently asked questions about mouse baiting

The CSIRO rodent research group generally considers anything over 500 mice per hectare as being a plague.

Mice living under field conditions have a seasonal pattern of breeding. This generally begins in early spring and can continue into late autumn the following year.

Mice living in unfavourable seasonal conditions may have a shorter breeding period, while those with nests and good cover are likely to have an extended breeding period.

Research suggests that it is the quality of the food more than the quantity of food that extends the breeding season.
