Which of the following options is NOT a recognized type of cockroach found in Colorado?

The Asian cockroach is indeed not recognized as a common or established type of cockroach in Colorado. While it is a species that exists elsewhere, particularly in warmer climates like the southeastern United States, it does not have a significant presence in Colorado's varied climate, which may be less favorable for this particular species.

In contrast, the German cockroach, American cockroach, and Oriental cockroach are well-documented in Colorado. The German cockroach is especially common in residential areas, often found in kitchens and bathrooms. The American cockroach, which is larger, can also thrive in both residential and commercial settings, while the Oriental cockroach is typically found in damp, dark areas. Understanding the distribution of these species is crucial for effective pest management, which is why recognizing that the Asian cockroach is not prevalent in Colorado is key for pest control professionals operating in the region.
