What Are Smokey Brown Roaches?

The smokey brown cockroach is a relatively large species of cockroach often referred to as a "palmetto bug." Smokey brown cockroaches are closely related to the American cockroach but are distinguished by their slightly smaller size and uniform dark mahogany brown color. Unlike the American cockroach (which possesses a light-rimmed pattern on its thorax) the smokey brown cockroach's thorax is dark and shiny. The smokey brown does not have an eye pattern behind their head like the adult American cockroach does. This species is approximately 1-1/4 to 1-1/2 inches in length. Smokey-brown cockroaches are strong fliers and have wings that extend beyond their bodies; they are attracted to light.

Smokey brown cockroaches are prevalent in leaf litter, in and around shrubs, flowers and trees, tree holes, wood piles, garages, crawl spaces, attics, and greenhouses. It has also been found on roofs and in rain gutters feeding on bird droppings and plant materials. Smokey brown cockroaches can also survive in sewers.
