Primarily an outdoors species, most populations can be found living under the mulch in landscape beds, rocks, in leaf litter, or under porches. In more metropolitan areas, oriental roaches can be found in large numbers living in storm drains, sewers, basements, cellars or crawl spaces.
They are known for their preference of feeding on garbage, filth or material that has begun to decay. These cockroaches are very dependent upon water, and although they can survive for up to a month without food, these insects can not survive for more than two weeks without water.
On average an adult male oriental cockroach will live 110 to 160 days, whereas the adult female can live anywhere from 35 to 180 days. During that time, a single female oriental roach can produce approximately 130 offspring.
These can be responsible for foodborne pathogens such as E.coli and Salmonella since they prefer to eat garbage and decaying organic matter.
