My chicken feed is getting little tiny black beetles all through it. Now I'm not too concerned as I figure it's just extra protein, but this morning I feed the last of the old feed and figure it's a good time to clean out the container. I'm using a galvanized trash can. I've hosed it out, but what else can I do that is non-toxic? I have access to some seriously hot sun which I'm sure, when the metal from the can conducts the heat, will cook any residual eggs, right? Will I need to do anything else?
