I will need to feed my 5 month old leopard gecko repashy grub pie for the winter. The feeder insects from pet stores contain parasites, so I order all my feeders online. They don't survive shipping in the colder months, which is why I am feeding her the grub pie in winter. Do you guys know if I should dust the grub pie with calcium the same way I would an insect? Also how often should I feed juveniles and adults? I see different answers on different websites for the frequency of feeding.
