Pest Organisms / Oriental Cockroach
Lookalikes
The American cockroach is most often confused with it, but they separate easily: the American is larger (around 1½ inches), reddish-brown rather than near-black, and full-winged; the Oriental is darker, smaller, and short- or no-winged. Source: https://extension.missouri.edu/publications/g7384
Habitat helps too. American cockroaches gravitate to food businesses like restaurants and groceries; the Oriental sticks to cooler, wetter spots around drains and damp foundations. Source: https://extension.missouri.edu/publications/g7384
