That's a GREAT suggestion, Eggplant! (love the name, btw
) Cardboard tubes (toilet paper, paper towels, the rolls from boxes of foil and stuff are good too, and more sturdy) and plastic tubes or PVC that you rough up on the inside are also VERY good. The plastic and pvc are the best, IMO, because you can wash and reuse them, plus the crickets do very well in tubes, and are easier to dispense.
