Biosecurity alerts: Brown marmorated stink bug updates

Brown marmorated stink bug (BMSB) is not found in Australia, but pose a high biosecurity risk due to their tendency to hitchhike and highly mobile nature. It is not a human health risk but poses a risk to agricultural crops, and is a nuisance pest, seeking shelter in homes and vehicles in large numbers.

The department is working to prevent a BMSB incursion, but needs the help of anyone working around and in receipt of imported goods, agricultural industries, businesses and the public to report suspect BMSB, as well as other exotic pests. 

January 2019

Location: Fremantle

Status: Eradication program underway

On 28 December 2018, a single live Brown marmorated stink bug (BMSB) was found in a trap at Fremantle Port. This trap was one of 14 set as part of BMSB surveillance activities which are conducted by the Federal Department of Agriculture and Water Resources.

The WA Department of Primary Industries and Regional Development (DPIRD) is working closely with DAWR to put in place swift and effective response measures.

A residual treatment has been applied to a 100 metre buffer zone which includes buildings and vegetation. DPIRD has a 12-week trapping program underway to determine whether the pest has spread. A total of 49 traps have now been deployed with no further detections to date. 

BMSB are highly mobile and during the colder months in the northern hemisphere (between September and April) it is common for BMSB to take shelter in cargo, as well as vehicles and machinery, that are bound for Australia. In recent years there has been an increase in BMSB detections at Australia's border due to their spread throughout the United States and Europe. Stronger import measures have been put in place to help reduce the threat.  

We need YOUR help. Look and report.

What if I find something?

If you find dead or live bugs suspected of being BMSB, you need to take IMMEDIATE action.

  • Don’t remove the contents of the container. Shut the doors and reseal.

  • Don’t allow the container to be moved – especially to an area outside if it’s in a warehouse.

  • Collect any dead or live specimens so our entomologists can confirm the species. 

  • Any live bugs should be held in a container that prevents them from escaping.


  • Photograph and map it using MyPestGuide™ Reporter (download the app or make online report).

  • Residents and businesses - call 9368 3080.

  • Anyone working around cargo - call the See.Secure.Report Hotline 1800 798 636.
