There is a lot of kind of cockroach’s species, but the most common problem are German, American, Asian, and Brown banded cockroaches that I encounter often. The most common problematic I found is the German roaches. They multiply at least every 27 days, and each egg capsule has an estimated 24 to 44 babies. The feces can cause smells and it might possibly trigger a person who has asthma or allergic to dust. Also, possibly contaminate the foods that are open and easy access to the cockroach.
