Walking Sticks (also known as Stick Insects or Stick Bugs) are an insect species commonly used in classrooms for educational purposes.
As walking sticks are species not native to San Mateo County, please do not release them. If they escape or are released outside their native habitat, they can become an invasive species, displacing local species. If you can no longer care for them, please look for another person to take them, or you can contact Stephanie Dole, PhD, The BeetleLady (www.beetlelady.com). She can add them to the walking stick colony she keeps for teaching purposes.
