In a landmark operation, Australian authorities seized over 100,000 illegal cockroaches from a commercial breeder in Bathurst, New South Wales, representing the largest confiscation of exotic invertebrates in the country’s history. The haul included Madagascar hissing cockroaches and dubia cockroaches, valued at around 200,000 Australian dollars (about $142,000). These species are illegal to import into Australia, as they pose significant risks to the environment and agriculture. The Madagascar hissing cockroach, one of the largest species globally, can grow up to 3 inches long, making it a popular choice for reptile food due to its size. However, authorities discourage their use for feeding pets, recommending alternatives like crickets. Australia's stringent biosecurity laws are designed to protect native wildlife and agricultural sectors from potential pest infestations. Those caught smuggling illegal animal or plant materials face heavy fines. The seized cockroaches will be euthanized, and while no charges have been filed against the breeder, officials have indicated that prosecutions may follow for similar offenses.
