Rats and mice are not only found around our properties and homes, but are also found in natural bushland settings where food resources are high. They are opportunistic and will eat eggs, small birds and other small mammals. In coastal areas, rats have been blamed for loss of sea bird populations.
What is the difference between a Black Rat, an Antechinus and a Bush Rat?
To the untrained eye, these species may look very similar but the native Antechinus and Bush Rat have some distinct differences that distinguish them from the introduced pests Black and Brown Rat. Rats are active during both day and night and are fearless around humans. Native rats are much shyer animals and prefer to nest in burrows under logs or rocks.
Antechinus
The Antechinus is a native nocturnal small carnivorous marsupial. They are grey-brown in colour, have a long nose, large thin ears and tail the same length as its body or shorter. The Antechinus tends to move across the ground in a hop, while rats run in a continuous motion.
Bush Rat
The Bush Rat is a native nocturnal rat that is grey-brown in colour, has a round body shape, round ears and a tail shorter than its body. The Bush Rat is an omnivore, eating insects, fruits, grasses and fungi. Bush Rats are one of the most common native species of rat found.
Black Rat
Black Rats are usually brown in colour, have large ears and eyes, pointed nose and its tail is longer that its body. The Black Rat is the species of rat that people will most often see in and around their homes.
Brown Rat
Brown Rats are brown in colour, small ears and eyes, blunt nose and its tail is shorter than its body. The Brown Rat can grow to almost twice the size of a Black Rat.
Mice
Mice, or the house mouse have distinctive chisel shaped front teeth, large eyes in a small head, large round ears and a scaly tail about the same as its body length.
