Put It In Metal: Canisters and boxes made of metal are another great barrier to rodents. Those big, ugly Christmas popcorn tins can hold a lot of food and supplies. Most metal containers will work for food storage, but avoid direct contact between your food and galvanized metal. Galvanizing is done with some pretty nasty chemicals.
Poison the Vermin:** Rat and mouse poison is a nice backup strategy for a rodent-free pantry. A top pick is d-CON, which is a proven and effective brand. Just make sure that your pets cannot reach the poison--and hope that your pets don't eat a poison-filled mouse.
