Smoky brown cockroaches are named for their striking dark, glossy brown colour. These pests possess a consistent, chocolate-brown colour throughout and have comparable size and shape as the American cockroach. However, their lack of yellow accents differentiates them from American varieties.
These cockroaches possess a length of 1¼ to 1½ inches and long, expertly designed wings. They use their wings to search for food or a mate. Their antennae can be as long as their body or even surpass it.
