Eek! Weevils! I had those once, they are terrible to get rid of. The best thing you can do is throw away any food not in airtight containers, even spices, that are in your cabinets. Then wash them thoroughly with a good soap and vinegar solution and make sure to get in the crevices well before putting anything back in there. Afterwards, make sure you keep all your flour, cornmeal, pancake mix cereals, and any other grain based foods in airtight containers, preferably in the refrigerator. Good luck with these buggers, they are dreadful!
