BATHURST, NEW SOUTH WALES — In a major biosecurity operation, Australian authorities have confiscated more than 100,000 live illegal cockroaches from a commercial breeder in Bathurst. This operation, carried out in May and confirmed by officials on Friday, stands as the nation’s largest-ever seizure of exotic invertebrates.

Operation Overview

The massive haul, valued at approximately 200,000 Australian dollars ($142,000 USD), was seized by the Department of Climate Change, Energy, Environment and Water. The illegal collection consisted of two specific non-native species:

• Madagascar Hissing Cockroaches: Known as one of the world's largest roach species, they can measure up to 3 inches (8 cm) in length—significantly larger than Australia's common domestic species.

• Dubia Cockroaches: Also an exotic species that is strictly prohibited from importation, breeding, or commercial sale within the country.

  

The Threat to Biosecurity

Australia maintains some of the world's strictest biosecurity controls to protect its unique native wildlife, agriculture, and horticulture sectors. Officials emphasized that exotic cockroaches have not undergone environmental risk assessments, making them potential carriers of foreign diseases or invasive threats that could devastate the local ecosystem.

Local snake catcher Stefanie Lesser noted that these large roaches were likely being trafficked as a cost-effective food source for pet reptiles, as their size allows owners to feed fewer insects. Authorities have urged pet owners to exclusively use legal alternatives, such as crickets or wood roaches, to feed their lizards.

Legal Status and Enforcement

The Department of Climate Change, Energy, Environment and Water confirmed that these species are entirely illegal to keep, breed, or sell, regardless of their origin. While no charges were laid against the Bathurst breeder in this specific instance, officials warned that future offenders face potential prosecution and heavy fines.

The seized insects have been marked for euthanasia and disposal. The government continues to remind the public that smuggling undeclared animal or insect material into the country is a serious crime with long-term ecological consequences.
