The Invasive Species Council has lodged a submission opposing an application to add the dubia cockroach (Blaptica dubia) to Australia’s Live Import List.
The application argues that listing the species would provide a regulated pathway for an existing domestic trade. We disagree. Dubia cockroaches reproduce rapidly, have flexible diets and can tolerate a broad range of temperatures. They could establish across tropical and subtropical parts of Australia, including some of our most biodiverse landscapes.
Commercially traded dubia cockroaches are also known to carry parasites and pathogens that could spread to native cockroaches and other wildlife. These risks have not been adequately assessed.
Approving the application could also reward an illegal trade and create an incentive for other exotic species to be smuggled into Australia in the hope they will later be legalised.
We have asked the National EPA to undertake and publish a rigorous environmental and disease-risk assessment, establish an amnesty for existing keepers to surrender or destroy their colonies, and advise the Environment Minister to refuse the application.
