Snap traps work, they are cheap but yucky. I use an electronic trap, works well and is way less messy. Do not use rat bait, they will die anywhere, you might not find them until you smell them. Also bait that kills rats will also kill anything that consumes that rat. mice will carry bait to the nest, and that could lead to an other animal getting to it and killing them also.
Hi Marcia, maybe this article will help with the problem.

Catch and release traps. You don't want the dying and rotting in among your stored items.
