I have started to purchase waxworms for my jax and veiled, and i need to know how to properly feed and house them. I ordered them from LLL Reptile, and they come in a container with wood shavings. Do i keep them in this substrate? Or just keep them in a substrate-free container? Also, what can I feed them so they won't get wet or turn black and die? Thanks for any info, i can keep crickets just fine, but all my worms keep on dieing or losing weight and I don't know why. I have tried lettuce and dry cereals, but i don't know if that is what i should feed them.
