I've started just storing my flour in the freezer, regardless. I think it makes more sense than having to worry about those doggone weevils, and since I buy small bags of flour, as a rule, it doesn't generally crowd my freezer too much.
I have also found that since I moved into a house with 50s era metal kitchen cabinets, the weevil problem seems to be minimized. Maybe they aren't as apt to breed in metal cabinets as they are in those made from wood or MDF. I don't know if that's the case, but it has seemed like that to me, and we've been living here since 2008. I don't think I've seen a single weevil. They were real problems in our apartment complex, and my mom, whose kitchen has wooden cabinets, has also had issues with them. She keeps her flour in the freezer, too.
