They are drugstore beetles. Drugstore beetles and their cousins, the cigarette beetles are pantry pests. They can infest all kinds of dried goods including pasta, cereals, oatmeal, cornmeal, crackers, cake mixes, cookies, dried fruit, spices, chocolates, dog and cat food, and the list goes on and on. You will have to search, discover, and clean. You may have to store all of your dried goods in heavy plastic containers until you get everything cleaned out. Storage in a freezer is also acceptable.
