What should I do if I find mice in my pantry?

Greg Baumann, Pest Sherpa

Short answer: Put on rubber gloves, empty the pantry, and separate damaged packages from undamaged ones into large plastic bins or bags. Take everything outside to inspect. Discard any packaging mice gnawed, even if you see no food damage, and make a list so you can replace it. Then take control steps, either with a professional or DIY trapping and exclusion. Prevention afterward means sealed bins and closed entry points.

Gear up and empty the shelves

If you find that there are or have been mice in the pantry, put on rubber gloves before you start. Remove all items from the pantry. Separate damaged packages from undamaged ones into large plastic bins temporarily, or into plastic garbage bags. Working in gloves keeps you from handling contaminated packaging with bare hands.

Inspect outside and discard gnawed packaging

Take the containers outside and inspect. Any packaging damaged by mice should be discarded, even if there are no signs that they got to the food itself. Make a list of what you throw away so you can replace it with fresh product. Do not put gnawed packages back on the shelf “just in case.”

Then control the mice

If you disturb and scatter some mice while clearing the pantry, take steps for control. That can mean calling a professional or taking DIY action with traps and exclusion. This page is about the pantry cleanup and food decision, not a full trapping how-to. For identification, habits, and control layout, use the house mouse guide. If you are sorting droppings while you clean, see how to identify mouse droppings.

Stop the next round

Cleanup without prevention invites a repeat. After the shelves are clear, store opened pasta, rice, chocolate, and similar dry goods in durable plastic bins, keep overnight pet food off the floor, and seal exterior and garage entry points.

Summary checklist

• Gloves on. Do not handle contaminated packages bare-handed.
• Empty and separate. Damaged vs undamaged into bins or bags.
• Inspect outside. Discard any gnawed packaging, even without visible food damage.
• List and replace. Write down what you discard so you can restock fresh.
• Control the mice. Pro or DIY; then seal and store food properly so it does not restart.
