The Florida woods cockroach is about 38-45 mm long as an adult and is often called the “stinking cockroach”; it produces a foul-smelling fluid to protect it from predation. It is dark reddish-brown to black. The nymphs have broad yellow bands on the top of their thoraxes.

It is commonly found in leaf mulch, wood piles, and under rotting logs. It’s often called a palmetto bug as well.
