dude biscuit they dont eat leaves, i order them from this hippy garden store in my area and i stick them in my tent, once they eat all the bugs in the tent they have a tendency to head out looking for food so what you can do to keep them around i sill take a plastic cup and wad up a paper towel and pour coke or sprite in it so they have something to eat, also they like apple slices and bits of oranges, anything sugary so keep them around, my guess is that if they keep finding their way in to your room chances are that there is something in there they want...like bugs or mites, i mean shit they wont hang out anywhere there is no food
