Which cockroach is commonly found in boiler rooms and sewers?

The American cockroach is often found in boiler rooms and sewers due to its preference for warm, moist environments. These roaches are known for their ability to tolerate a wide range of temperatures and conditions, which makes them well-suited for urban environments where they might find plenty of food and shelter in areas like boiler rooms.

They are also attracted to areas with decaying organic matter, which is often found in such settings, contributing to their prevalence there. Their size, approximately 1.5 to 2 inches long, and their reddish-brown color make them easily identifiable. While other species of cockroaches may be found in similar habitats, the American cockroach is particularly notorious for its adaptability to the conditions present in boiler rooms and sewer systems.
