Care & Wellness:

Although a popular consensus among most people is to not like roaches, our keepers care for several colonies of roaches, including Madagascar hissing cockroaches who serve as animal ambassadors! Every day, their keepers do wellness checks and assess food consumption and overall health between the different colonies.

Behavior:
  • Some other species of roach have wings, but Madagascan Hissing cockroaches do not have wings and cannot fly.
  • These roaches have a thick armor that they use to protect themselves from predators but first will try to flee or hiss when threatened.
  • The hissing sound made by these roaches comes from tiny holes, called spiracles, alongside the body, where air is pushed out if needed for defense or mating rituals.
  • Males have large horns on the top of their heads, and they can often be seen using them and fighting over favorite spots and females within the enclosure!
  • Hissing cockroaches are good climbers and are most active at night.
