Which of the following cockroaches is known for favoring warm areas of multi-family dwellings?

The American cockroach is known for favoring warm areas of multi-family dwellings due to its preference for higher temperatures and humidity levels. This species, which can often be found in kitchens, basements, and near pipes or heating systems, thrives in environments where food and water are readily available, making multi-family housing an ideal habitat.

The allure of warmth in areas such as these is largely because American cockroaches can survive and reproduce more effectively in favorable conditions. They are also drawn to the heat generated by appliances and plumbing, which is common in multi-unit structures.

In contrast, while other types of cockroaches like the German or Brown-banded cockroach might also inhabit multi-family buildings, they have different specific environmental preferences. For example, the German cockroach is more closely associated with indoor areas and typically prefers places with available food stocks.
