They make great pets for kids, and are showing up in more and more classrooms and zoos.
Some species prefer others including oak, hawthorn, and raspberry.
A daily misting of the cage with a spray bottle allows phasmids to drink from small water-droplets. They seem to find this easiest. It is best to avoid spraying the insect directly, because there is the small chance that it can lead to infections. Also, nymphs can drown in a small drop of water, so be careful that your spray-bottle produces a fine mist. Aside from this, a clean cage is about all the typical phasmid requires.
