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.
The oriental cockroach is a large cockroach species that is commonly found in Tennessee and many parts of the country. Like American cockroaches, Oriental roaches are an occasional invader and will enter homes and businesses from the outside. You will find them in damp basements, under sinks and in washing machines.
