There is around 4000 types of roaches in the world and about 70 living in USA. The most widespread species are American, German and Brownbanded cockroaches, in the northern regions of the country there’s also an Oriental cockroach. All of them can be dangerous for humans as they usually transfer germs, while their shedding skin and droppings can cause allergies and respiratory diseases.
Each cockroach specie has its own preferred habitat and food habits. Most of them come into a house through the drain system, but some prefer drier places. For example, Brownbanded cockroach often uses cabinet and bedroom furniture for laying its eggs — people used to dealing with other kinds of cockroaches are not used to looking for them in such places.
