Australia seizes over 100,000 illegal cockroaches in record wildlife raid

Australian wildlife officers have seized more than 100,000 illegal cockroaches in a raid on a breeding facility in New South Wales, in what is reported as the country’s largest-ever insect confiscation. The insects, including Madagascar hissing and dubia cockroaches, were being illegally bred and sold mainly as reptile food, despite being banned under Australia’s strict biosecurity laws. Authorities say the operation highlights ongoing efforts to prevent the spread of invasive species, and the seized insects will be destroyed.

Wildlife officers in Australia have carried out a major raid in New South Wales, seizing more than 100,000 illegal cockroaches from a commercial breeding operation in what authorities described as the country’s largest-ever confiscation of exotic insects.
The operation took place in May in the rural town of Bathurst, located about 200 kilometres west of Sydney. Officials said the raid uncovered large quantities of Madagascar hissing cockroaches and dubia cockroaches, both of which are prohibited under Australian law. The country’s strict biosecurity regulations ban the importation, breeding, keeping, or sale of these species due to the risks they may pose to the environment and agriculture.
Authorities estimated the seized insects to be worth around $142,000 on the black market. The Madagascar hissing cockroach, one of the largest cockroach species in the world, can grow up to 7.5 centimetres in length, making it significantly larger than common native Australian cockroaches.
According to environmental officials, the insects were being illegally bred and traded, primarily for use as live food for pet reptiles. The demand for exotic feeder insects has contributed to a small but active black market, despite clear legal restrictions. Officials urged pet owners to avoid illegal species and instead use approved alternatives such as crickets and wood roaches, which are considered safe under current regulations.
Australia is known for having some of the world’s strictest biosecurity measures, designed to protect its unique ecosystems and agricultural sector from invasive species, pests, and diseases. Authorities regularly conduct inspections and enforcement operations to prevent illegal trade in plants, animals, and insects, and offenders can face significant fines or other penalties.
A spokesperson for the environment department said the government takes breaches of national environmental law very seriously, stressing the importance of protecting Australia’s biodiversity from potential ecological threats.
Officials also confirmed that the seized cockroaches would be euthanized in accordance with biosecurity procedures, bringing the large-scale operation to a close.
