There are over 3,000 different species of cockroaches-some are considered pests while others are beneficial in their natural environment. The three main types of cockroaches commonly found in homes in South Africa include the German cockroach, Oriental cockroach and American cockroach.
While still considered a type of roach, palmetto bugs are not American cockroaches. They arenât German cockroaches either, but people often mistake these bugs for one of these other two species. The key difference between a palmetto bug and other types of roaches is that the palmetto is primarily found in Florida and other coastal states. Yes, youâll find the American cockroach in Florida and other parts of the U.S. as well. But palmetto bugs differ slightly in body shape, size and color.
