I love this article. While I do not purposely catch insects and eat them, I do not discard meals that have critters. In fact, as a science instructor and writer, I sift old bags of cornmeal and look for the different stages of insect metamorphosis. The mummy looking pupae stage is actually very cool looking! To prevent the growth and reproduction of critters in meals, store them in the freezer or refrigerator. This is where I keep my flour and cornmeal--unless I need the bugs for a science investigation. Don't worry about those bugs. Sift the flour or cornmeal to remove visible adults, and forget about what you can't see. There is no way to remove insect eggs from packaged grains. They do add protein to your foods.

Thanks for this article! I had found these bugs in a container of whole oats, and then in an UNOPENED container of whole oats, but had no idea what they were. At least now I know. I also know better than to buy the large container of oats because it tends to sit in my pantry for months. Going forward, I'll buy the smaller container. I may also begin storing it in the freezer as I do my cornmeal.

Is there a difference between weavels and booklice?  
And are they safe to eat? Or should I throw the flour away? A few bugs don't really bother me as long as they're not harmful.
