Where do German roaches primarily prefer to live?

German cockroaches primarily prefer to live in kitchens and bathrooms due to their need for warmth, moisture, and access to food. These environments provide a consistent supply of food sources such as crumbs, spills, and leftover food. Additionally, the warm and humid conditions found in kitchens and bathrooms are ideal for their survival and reproduction. Their preference for these areas makes them a common pest in residential settings, highlighting the importance of maintaining cleanliness and addressing any potential infestations promptly.

The other choices represent locations that may not offer the same combination of resources. While they may occasionally inhabit basements or closets, these areas generally lack the same level of access to food and moisture compared to kitchens and bathrooms, making them less suitable for German cockroaches.
