It is about 12.5mm in length, brown in colour, with two dark streaks on the area just behind the ahead.
Adults are winged but the nymphs are wingless.
They have two small projections on the end of their abdomens. They move quickly and prefer the dark. If you see them in light, there are usually many somewhere close by. The cockroach develops from an egg to the nymph stage, them to adulthood. From egg to adult takes about 3 to 4 months, and the adults may live for up to 1 year.
