The most common cockroach to invade your home or business in South Florida is the German Roach. This small roach reproduces faster than any other and has built up resistance to many chemicals, which makes it the most difficult to eliminate. The American Roach is a large outdoor dwelling roach with wings many call a Palmetto Bug. If you start seeing a lot of them in your home, you may need to treat inside your walls and attic where they tend to breed.
