Rat-Proofing the Kitchen: Food Storage Tips

Food is the biggest reason rats come into homes. If the kitchen offers easy meals, rats will keep finding ways in, however many gaps you seal. Good food storage and kitchen habits take away the reward.

This guide gives practical tips for storing food so that rats lose interest.

The short answer

To rat-proof a kitchen through food storage, keep dry foods such as rice, wheat, pulses, flour and snacks in sealed metal, glass or thick hard-plastic containers with tight lids, keep nothing in open sacks, paper bags or thin plastic that rats can gnaw, store containers off the floor, clear crumbs and spills, wash dishes at night, keep waste in lidded bins and remove it daily, and manage pet food too. Combine with sealing gaps and checking for signs.

Containers that work

• Metal tins and drums with tight lids: The most rodent-resistant.
• Thick glass jars: Good for small quantities.
• Heavy, hard plastic containers with locking lids: Better than thin plastic.

Avoid cardboard, paper, cloth and thin plastic bags, which rats chew through easily.

Storing common foods

1. Grains, pulses, flour: Transfer from sacks into sealed containers as soon as they arrive.
2. Snacks and packaged foods: Keep in cupboards with doors that close tightly, or sealed tins.
3. Fruit and vegetables: Keep in covered baskets or the refrigerator, and avoid leaving them on the floor.
4. Onions and potatoes: Store in a raised, covered container.
5. Oils and sweets: Keep in closed containers.

Daily habits

• Wipe counters and the stove and sweep crumbs every night.
• Wash dishes before bed, and do not leave plates in the sink.
• Take out waste daily and keep bins lidded.
• Do not leave food on counters overnight.
• Do not store food on the floor.

Pet food

• Store dry pet food in sealed containers.
• Feed at set times and remove leftovers.
• Wash bowls and clean the feeding area.

Kitchen layout

• Keep the floor clear so you can see droppings and signs.
• Keep gaps behind appliances accessible for cleaning.
• Do not store food in cardboard boxes under the sink.

What to throw away

Discard open food with gnaw marks, droppings or a suspicious smell, and anything that may have been contaminated. See our guide on pantry food and rats.

When to call a professional

If rats are still coming despite good storage, they may be getting in through gaps or finding food elsewhere. A professional can find the source.
