The brown cockroach (Periplaneta brunnea) is a species of cockroach in the family Blattidae. It is probably originally native to Africa, but today it has a circumtropical distribution, having been widely introduced.[1] In cooler climates it can only survive indoors,[2] and it is considered a household pest.[1]

This cockroach is similar in appearance to the American cockroach (P. americana), but darker in color and with thicker, wider, triangular cerci. It is a reddish-brown color and has fully developed wings.[2] It reaches up to 4 centimeters in length.[1]

It produces an ootheca about 1.2 to 1.6 centimeters long containing about 24 eggs on average.[3]

It is an omnivore.[2]
