The Madagascar roach is a large brown insect that measures 2 to 3 inches in length and has a lifespan of up to 5 years. These roaches are also known as hissing cockroaches because of the noise they make by exhaling air to establish dominance or attract mates.
Unlike most cockroaches, these insects do not try to invade human territory. They instead live on the floor of wooded areas. Madagascar roaches have one pair of antennae and no wings. Males have large horns they use for fighting with other roaches. Females give birth to as many as 60 offspring at one time.
