I could have sworn I saw somebody say that they put mealworms in their tort. table substrate and then I came across a small thread about bio-active substrate with the other listed animals. What's the point? Won't those little critters crawl out and eat you in your sleep? If they don't hop out, how could I start this? Of should I? Just let worms roam around and have my ruski peck at them? What if they breed and get out of control?
