Cockroaches Are A Pest
There are in fact some 3500 odd species of cockroaches around the world, but not all of them are considered a pest. We consider a cockroach a pest if it is invasive and migrates/lives in our homes.
In and around Brisbane there are really only 3 or 4 main nuisance breeds that live in proximity to us and whom take up residence in our homes. The rest of the cockroach breeds that are found in Australia and in and around Brisbane and the Gold Coast live in our yards, in bush land, in local forests and generally they remain outdoors. It would be a rare situation to see one of those species of roaches coming into and taking up residence in a family home.
We call certain breeds of cockroaches a pest because they live in our homes and are well known carriers of certain diseases. We also know they spread these diseases to humans, and its because of this that they are classified as a health risk. Because of some of the pathogens that they carry they can place individuals and whole families at server risk of some nasty health problems.
