Flour bugs don't just spontaneously appear. Chances are if you have them, you brought them in with something you bought that was already infested with them. Take whatever is infested and get rid of it. Then check all other grains. These bugs are small enough to get into cardboard and can eat through plastic bags. Clean the area out, vacuum it out thoroughly, and sanitize the shelves. Store your goods in sealed containers. To keep pests out for good, you need to check the area regularly. Larvae can remain and re-start the infestation. You can place some bay leaves around the pantry as a future deterrent, but this is no replacement for regular check-ins and cleaning when it comes to pantry pest prevention.
