Eradication of Norway rats (Rattus norvegicus and house mouse (Mus musculus) from Motuihe Island, New Zealand

Motuihe Island is located within the Waitemata Harbour, Auckland, New Zealand. Mice (Mus musculus) and Norway rats (Rattus norvegicus) were introduced to this island at an unknown date. Rabbits (Oryctolagus cuniculus) and feral house cats (Felis catus) are present. Most of the island is a pastoral farm. Past anecdotal records of rats and mice suggest that there have been significant changes in their abundance from year to year. Two aerial applications of Talon 7-20, a cereal-based anticoagulant rodenticides containing brodifacoum, were made in 1997 with the intention of eradicating both the rats and the mice. Trapping for rats and mice in 1999 and 2000 failed to detect the presence of either species and the project is deemed to have achieved eradication.
