Which cockroach is known for living mainly outside and is often associated with tropical areas?

The American cockroach is recognized for its preference for outdoor habitats, particularly in warmer climates commonly found in tropical regions. This species thrives in environments that provide moisture and debris, which are typical in outdoor settings. Unlike other cockroach species that tend to inhabit indoor spaces and thrive in human-made environments, the American cockroach is often found in areas like basements, sewers, and woodpiles outdoors.

This cockroach, also known for its larger size and distinctive reddish-brown coloration, can sometimes be seen in urban areas but is less associated with indoor infestations compared to species such as the German cockroach or the brown-banded cockroach. Its habitat choice makes it a notable species, particularly in discussions about pest management in areas where warm climates support its lifecycle. The other cockroaches mentioned generally prefer indoor environments or have different habitat affiliations, thereby distinguishing the American cockroach's outdoor tendencies.
