       Madagascar Hissing Cockroaches are large, wingless, live-bearing cockroaches that may be the best starter cockroach species. They're relatively common, inexpensive, and very interesting additions to any collection, as well as great food items for reptiles, large tarantulas, and large centipedes. Madagascar Hissing Cockroaches have a tough exoskeleton for protection, for they do not possess wings like many other cockroach species. They can also produce a loud hissing sound to scare away predators. Madagascar Hissing Cockroaches generally live 2 to 3 years as adults, but some adults can live for up to 5 years. They can be raised in large numbers in a matter of months, yet are not a pest species. Madagascar Hissing Cockroaches have been used as creepy effects in movies for many years as well. The Madagascar Hissing Cockroach makes an amazing, exotic, and easy-to-care for insect pet!
