I use water crystals for hydrating my crickets. The crystals do not mold. When they get dirty from the crickets walking on them and pooping on them I just recycle them into the garden and put a new dish of crystals. I buy the big 50 pound bag, as I also use the crystals for gardening. I have never had any cannibalization with my crickets in the two years I 've been raising them. They also get the dust, or meal, from the rodent block bags, and ground up cat food.
