The brown marmorated stink bug (the species most commonly encountered indoors) is native to East Asia - namely China, Taiwan, North & South Korea and Japan - and has been introduced to the United States and parts of Western Europe. The stink bugs are exotic pests to Australia, and have been suspected to have arrive as hitchhikers to Australia on cargo/shipping goods, vessels or personal effects, and may be more common during certain times of the year. Stink bugs pose a high biosecurity risk to Australia's agricultural industry.
Stink bugs are strong fliers and can fly to a new habitat - up to 2km a day - or may even hitch a ride in shipping containers or on cars.
The brown marmorated stink bug is not capable of biting or stinging humans.
Stink bugs rely on their foul smell for protection against predators such as birds, lizards, and mice or any other animals that prey on them. The noxious chemical flows from the two glands on the stink bug’s thorax.
Like many other exotic pests to Australia, stink bugs are attracted to the warmth that can be found inside businesses. Stink bugs are attracted to bright lights so it is advised to keep exterior lighting turned off and window blinds pulled down. If you have discovered the brown marmorated stink bug on your premises, they must be reported immediately to the Department of Agriculture and Water Resources hotline 1800 798 636
