Answer 2

Different kinds of flies, of coarse, eat different kinds of things. However, if you are talking about house flies, they will eat almost anything. Whatever they eat can't be unnatural, so they can't eat a toy or packaging. However, they can eat what you eat, and they can eat whatever is outside, which obviously includes manure and carcasses. So they will eat anything, as long as it's not humanly processed to the point that you can't eat it either.
