We have two parrots and shop at a very good, reputable bird specialty store for their food and toys. We complained to the manager once about the larger parrot's more expensive food having moths in it one time. (You're right about it being hard to get rid of those moths once they're flying about!) We were told this just happens sometimes and the moths aren't harmful in the least, but that we could put the bags of parrot food in the freezer as soon as we got home with them. When frozen, it would kill off any unwanted pests. Since we've been doing this, we have never had any moth problem again.
