answer:Welcome to Fluther. What can you tell us about the insects? Obviously, not all insects are equally dangerous and not all are dangerous in the same way. What kind of bread are we talking about, first? That might help to narrow down what kind of insects would be attracted to it. Personally, I don’t think I’ve ever seen a loaf of bread attacked strongly by insects. Mold, yes, and depending on the type of mold that can be a problem. But depending on how you attempted to clean with bleach, that stuff can fuck up your breathing. I’d be more inclined to think you may have harmed yourself with that.
