5-8cm Madagascar Hissing Cockroach

"Likely Smuggled In as Reptile Feed"

Australia has been shocked by the discovery of approximately 100,000 giant cockroaches, which are banned from being bred in the country, found in bulk at a breeder's warehouse. Authorities have confiscated all of the cockroaches.


According to reports from international outlets such as the Associated Press on June 5 (local time), the Australian Department of Climate Change, Energy, the Environment and Water (DCCEEW) announced that it had raided a breeding facility in Bathurst, New South Wales, last month and seized illegal cockroaches.

The confiscated cockroaches include the "Madagascar hissing cockroach" and the "Dubia cockroach," totaling around 100,000 individuals. The market value of these cockroaches is said to be close to 200,000 Australian dollars (approximately 219 million won).


The Madagascar hissing cockroach, known as the "world's largest cockroach," grows to a length of 5 to 8 centimeters. This species produces a whistling, wind-like sound by forcing air in and out of its body when threatened.


A local reptile expert told the media, "It is highly likely that these giant invasive cockroaches were illegally distributed primarily as feed for reptiles such as lizards." The expert added, "Because of their large size, even a small number can provide sufficient nutrition, making them attractive to breeders looking to reduce costs."


In Australia, breeding or distributing invasive cockroach species in large quantities is illegal. If caught, violators can be fined up to several thousand Australian dollars. The Department of the Environment issued a statement warning, "Regardless of how they are obtained, possessing, breeding, or selling these cockroaches in Australia is strictly illegal."


Australia operates one of the world's most stringent "biosecurity" systems to protect not only its unique continental ecosystem but also its domestic agriculture and livestock industries. Smuggling unreported foreign animals, insects, or plants can result in hefty fines if detected.



The Department of the Environment emphasized, "Invasive cockroach species that have not undergone environmental risk assessments can spread deadly diseases or harm native wildlife in the local ecosystem." Authorities announced that, instead of filing separate criminal charges against the breeder caught in this case, all 100,000 confiscated cockroaches will be euthanized.
