At the last couple reptile expos I've been to they've been giving out Zoo Med bags with a bunch of food sample packets. Stuff like turtle food, betta food, musk/mud turtle pellets, bearded dragon pellets and so on.

I'm never going to have these types of animals and hate to throw them out. Could I add them to my dubia roach chow? Are there any specific ingredient that could be harmful to the roaches or passed on to the frogs?
