Thanks, I can try it again. Just got back from pet store and sure enough their wax worms were dead again! Finally found live ones that were not black. Why is this you ask? Well, no one there checks them and their fridge might be too cool. The first answer is right, no one checks them and other people most likely went home like I did before with dead ones. Just read about how to keep these worms alive, the fridge butter holder must be too cold. I can store mine in garage or basement, might check temp there first. I got new mealworms: will try keeping them differently, too. I need a break from crickets for a while.
