Rats in the Kitchen: Causes and Fixes

Few things are more unsettling than finding signs of a rat in the kitchen: droppings near the grains, chewed packaging, a scurry behind the stove at night. The kitchen offers food, water and warmth, and rats are very good at finding the way in.

This guide explains the causes and what to do.

The short answer

Rats come into kitchens for food, water and shelter, and they get in through gaps around pipes, drains, vents, gaps under doors and cabinets, and openings behind appliances. Signs include droppings, gnaw marks on packaging and cabinets, greasy rub marks along walls, scratching noises and a musty smell. To fix it, remove food and water access, store food in sealed metal or thick plastic containers, seal gaps and entry points, clean thoroughly, and use traps or professional control. Closing the entry points is essential, or new rats will arrive.

Why rats come to kitchens

• Food: Grains, pulses, snacks, pet food and waste.
• Water: Leaks, dripping taps and damp areas.
• Shelter: Warm, dark spaces behind appliances and cabinets.
• Easy access: Gaps around pipes, drains and vents.

Signs of rats

1. Dark, pellet-shaped droppings, about the size of a grain of rice or larger.
2. Gnawed packaging, soap, wires and wood.
3. Greasy smears along walls and skirting.
4. Scratching or scurrying sounds at night.
5. Nests of shredded paper or cloth.
6. A musty, ammonia-like smell.

Where they get in

• Gaps around pipes under the sink and the gas line.
• Drains and floor traps without covers.
• Gaps under doors and around the chimney or exhaust.
• Openings behind cabinets and appliances.
• Balcony and utility area doors.

Fixes

1. Store food securely: Use metal or thick, lidded containers. Rats can gnaw through thin plastic and cardboard.
2. Clean up: Wipe spills, sweep crumbs and wash dishes at night.
3. Manage waste: Use lidded bins and remove waste daily.
4. Fix leaks and dry the sink area.
5. Seal entry points: Use steel wool or mesh with cement or suitable sealant. Avoid blocking ventilation.
6. Cover drains with tight covers or mesh.
7. Use traps or call professionals. Place traps along walls where rats travel.

Safety

• Keep poison baits away from children and pets, or use enclosed stations placed by a professional.
• Wear gloves when cleaning droppings and wash hands.
• Do not touch dead rats with bare hands.

When to call a professional

If you see rats or fresh droppings regularly, call a professional. They can find the entry points, treat safely and proof the kitchen.
