is it possible for say a maggot or meal worm type food to survive being swallowed, and then " eating " your chams innards ? or biting their mouth ? I have some fly larva, home grown but as I watched them eating, they really have a nasty set of " teeth" - now I am nervous to feed them with out smashing their heads - YUCK ! I think my chams are now responsible for more of my gray hairs then my kids !!
