Heating the bin is an important part of keeping crickets from dying. You can use organic, fruit and veggie baby food as a moisture source, or unsweetened applesauce. I prefer those to gel crystals and when fresh produce isn't available. A lot of people use cricket crack, bug burger, or bug buffet. Those are good starts, but I prefer to make my own gutload and it costs me $30ish a pound.
