They can be found glued to a service, such as under cabinets, or in basements, behind appliances, etc.

Once hatched, nymphs start out light, grayish-brown color but then mature into reddish-brown, with the process taking 6 to 12 months. American Cockroaches can live anywhere from 168 days to a little over 2 years.
Habitat and Behavior
American Cockroaches prefer to live outdoors but they do enjoy areas that are damp and warm such as sewers. American Cockroaches are active all year round and often find their way into a home while traveling through plumbing and stick around kitchens, basements, garages, laundry rooms, and bathrooms.
You may notice an American cockroach in the home scurrying quickly when turning the light on in a dark area. American Cockroaches are also nocturnal and are active at nighttime which is when you are most likely to see them out of hiding.
