Cockroaches, also known as ‘roaches’, are among the most primitive of insects, dating back to the Carboniferous era 280 million years ago. These pests are omnivorous and will eat anything of nutritive value, including soap and glue to survive. There are only two domestic species of cockroaches, requiring the food water and indoor harborage provided by humans. These are the German and Brown-banded cockroaches, with the German being far more common in commercial establishments.
