Many different types of pests are drawn to food -- cockroaches, ants and mice, to name a few. Don't tempt them by leaving out last night's leftovers because you're too tired to clean up. Put away all food as soon as you're finished chowing down, making sure everything is well-sealed. Lightly covering a dish with plastic wrap won't do it. Remember, too, that we're not talking just about cooked food. Mice, for one, will eat foods like cereal, ramen noodles and pretzels. (And enjoy them.) Store those items in containers with tight-fitting lids, and keep them on high shelves -- not on the floor, on the counter or in corners [source: PR Newsire].
