OK! Another good question. I did some reading and thinking on that. When I have a good amount of beetles I will make one more of the same setup for the beetles, just checked the garage and I do have one more container, and see how that works out. Since the boxes are small and I am harvesting regularly for my quails food I'm not sure how many beetles I will be dealing with this early on. If its not to many I will be keeping them all together. Thank you for the questions! It gives me the opportunity to refine my plan. Hope this answers your question, please ask more anytime.
