The risk to Australia
The aggressive nature of the Asian tiger mosquito makes is a major human and livestock health risk. Its bite can spread serious diseases such as dengue fever, yellow fever and several types of viral infections that can cause swelling to the brain (encephalitis).
What the Asian tiger mosquito looks like
An adult mosquito is about 4 millimetres in length, is black and white in colour and has a distinctive white stripe down the centre of its back. Eggs are elongated, about 0.5 millimetre in length and are dark brown to black in colour. Eggs are laid just above the waterline and can survive for up to a year in a dry state. Larvae develop through four stages before maturing into adults.
What to look for and where
The Asian tiger mosquito is most likely to enter Australia as eggs or larvae in cargo capable of holding water such as tyres, machinery, bulk steel and yachts. The eggs are also regularly found on imported lucky bamboo.
