- Australian Cockroach

- This cockroach looks ugly, it has hairy legs and eye-pattern on
their thorax. They are reddish brown in colour, with long antennae and yellow
edges on the front part of forewings. They are pest in households. This
species of cockroaches, with the American Cockroaches and German
Cockroaches, have given the cockroaches order group a bad
name. They transmitted diseases when they occur in house and restaurants.
They contaminate food and must be controlled. Despite the name,
Australian Cockroaches are not
native to Australia. They originated from Asia. They became totally adapted
to the domestic life. We have more pictures and detail information in this Australian
