Current situation

Brown marmorated stink bug

Brown marmorated stick bug

NSW DPI is leading the response following the detection of the exotic pest, Brown marmorated stink bug (BMSB) at a warehouse in western Sydney after a container arrived from Italy.

To ensure this serious pest hasn’t spread, these activities are being assisted by Great Sydney Local Land Services and the Department of Agriculture and Water Resource.

Two rounds of surveillance and treatment have been undertaken within the warehouse.

People living and visiting the Glendenning area are asked to keep an eye out for Brown marmorated stink bugs.

Brown marmorated stink bugs can be detected by visually inspecting host plants. They are large bugs that can give off an unpleasant odour when disturbed.

Adult Brown marmorated stink bugs are approximately 12 to 17 mm long and 7 to 10 mm wide – similar in size to a five cent piece.

Brown marmorated stink bugs are variable in colour, but generally have a mottled brown coloured body with alternating light and dark bands on the antennae, legs and the side margins of the abdomen.

Brown marmorated stink bug feeds on a wide range of fruiting plants including ornamentals and vegetables. Preferred plants include apples, peaches, raspberries, sweet corn, green beans, capsicums and tomatoes.
