Australian officials have confiscated more than 100,000 live, illegal cockroaches from a commercial breeder in Bathurst, New South Wales. This operation, which took place in May, marks the country's largest-ever seizure of exotic invertebrates. The haul, consisting of Madagascar hissing and dubia cockroaches, is valued at 200,000 Australian dollars.
The Madagascar hissing cockroach, which can measure 2 to 3 inches in length, is significantly larger than the common Australian cockroach. Experts suggest these exotic species were likely being bred for the pet trade as a cost-effective food source for reptiles, as their size reduces the number of insects required. Officials have urged pet owners to use crickets or wood roaches instead.
Both species are illegal to import, keep, breed, or sell in Australia. The Department of Climate Change, Energy, Environment and Water warned that these insects have not undergone environmental risk assessments and could potentially spread disease or harm native wildlife. Australia maintains strict biosecurity controls to protect its horticulture, agriculture, and native wildlife from pest infestations, and those smuggling illegal animal or plant material face thousands of dollars in fines.
Although the cockroaches were seized, a spokesperson stated that charges were not laid against the breeder. The confiscated invertebrates will be euthanized.
