Long-haired Rat
Rattus villosissimus
The Long-haired Rat is a native Australian rodent famous for its spectacular population irruptions, or 'plagues', in the arid interior. For long periods during drought, this species survives in small, isolated populations in permanent refuge habitats. However, following extensive, widespread rainfall and the resulting boom in vegetation growth, their numbers can explode exponentially. During these plagues, millions of rats can spread out across the landscape, becoming a significant agricultural pest and a nuisance in rural communities. They are a fascinating example of a native species adapted to Australia's 'boom and bust' ecological cycle, but their plagues can have severe economic and environmental consequences.
For effective control and prevention, professional pest management is recommended.
