what are peoples experiences with mealworms? i got some slings recently p ornata p regalis a versicolor and m robustum,after looking for suitable crickets in the shops i drew a blank so i started using meal worms,i squish the head first before i put them in and my slings seems to love them,i am concerned though that if i put them in alive they would burrow and emerge as beetles,are these beetles edible to the slings and are they as much as a threat as a cricket could be?
