American cockroach

Warm, dark, and humid environments such as basements, sewers, and crawl spaces.

Omnivorous scavenger feeding on decaying organic matter, starches, and food scraps.

Nocturnal and highly agile; avoids light and rapidly flees when disturbed.

Acts as a major household pest that triggers allergies and transmits pathogens, though it aids organic decomposition in natural habitats.
