What color are Oriental cockroaches?

Oriental cockroaches are typically characterized by their dark coloration, ranging from black to a deep brown. This distinctive appearance helps differentiate them from other species of cockroaches, which may exhibit lighter shades. The dark color of Oriental cockroaches allows them to blend into their commonly found environments, such as damp basements or drains, making them less visible to potential predators.

The other colors listed in the options correspond to other types of cockroaches or insects. For example, light brown might be associated with American cockroaches, bright green is not a common color for cockroaches, and yellow does not correspond to any typical cockroach species. Understanding the color and appearance of various cockroaches is crucial for pest identification and effective pest management, especially when implementing control measures.
