The German roach prefers indoor environments, specifically kitchens and bathrooms, due to the warmth, moisture, and food availability.

They are particularly attracted to dark and protected areas such as crevices, behind refrigerators, under sinks, and other areas that offer a steady food supply and high humidity.
