Do stick bugs drink water

Answer 1

no

ADD:

They don't need to give them water directly as you would a cat or dog; but they do benefit from a light spraying of water on the plant food to keep the enclosure moist and allows the stick insects to drink droplets of water from the leaves.

Answer 2

Yes! All animals and plants need water! Just fill up a spray bottle and give the tank a few squirts once or twice a day.
