About the Madagascar Hissing Cockroach
Originating on the African island of Madagascar, the Hissing Cockroach thrives in humid subtropical climates. For this reason, they’re often kept as pets in temperature-controlled aquariums or in parts of the U.S. such as Florida. They got their name from the ‘hissing’ sound they make when disturbed – a similar defense mechanism to the common rattlesnake. The noise is produced through slits in the bugs’ abdomens and also plays a significant role in their communication and mating patterns.
Because they feed only on organic and plant matter, Madagascar Hissing Cockroaches like to nest beneath logs and other decay on forest or jungle floors. They feed on everything from leaves to fallen fruit and can live anywhere from 3-5 years in the wild! With such a long lifespan, Madagascar hissing cockroaches stay with their mothers for a long time after birth, usually at least 6 months.
Facts about the Madagascar Hissing Cockroach
This species of cockroach does not have wings but has excellent climbing capabilities. Though the females are slightly larger and usually docile, male Madagascar cockroaches are highly aggressive and can be seen (and heard) fighting with one another in the wild. In fact, males have “horns” in place of antennae which they use almost exclusively when fighting other males for dominance. The horns look like thicker, stronger antennae and may fall off and reproduce over time.
It is highly unlikely that you would ever spot a Madagascar Hissing Cockroach in your home. Not only are they not found in the U.S., they’re outdoor animals and do not seek out the comforts of shelter. If you come across a Madagascar Hissing Cockroach – either in captivity or in the wild – keep your distance. Suspect you may have a different type of roach problem in your home?
