If I see a weevil larva, I pretend I didn't. If I see several, I'm done.
I can buy into the tiny bits of protein part to a point. I don't believe
the eggs hatch inside us and don't worry about them. I live in a dry
enough climate that I've never experienced rancidity in flour. I just
threw out a one pound bag of flour unopened that had been in our travel
trailer for two years. But that was because my wife told me to.
I suppose you could sift them out if you had a mind to. If flour gets
more expensive, expect a run on sifters.
