Why are German cockroaches often found in kitchens and bathrooms?

German cockroaches are commonly found in kitchens and bathrooms primarily because they are attracted to food sources and moisture. These areas provide ideal conditions for them to thrive; kitchens often have plentiful food scraps and areas where food is stored, while bathrooms typically offer excess humidity from water sources and poor ventilation.

The combination of food and moisture creates a suitable habitat for German cockroaches, allowing them to easily access what they need to survive. Their preference for environments where food preparation occurs and where water is readily available explains their frequent presence in these specific areas of a home. This attraction is crucial for their reproduction and survival, enabling them to gather the resources necessary for their lifecycle.
