Mice: UK guides to getting rid of mice

The house mouse is the rodent UK households deal with most often. Mice are small, curious and able to squeeze through gaps of around 6 mm, so even well-kept homes get them, especially from October onwards when the weather turns cold and food outdoors becomes scarce.

The first signs are usually small dark droppings in kitchen cupboards or behind appliances, nibbled packaging, a musty smell, or light scratching in walls and ceilings at night. Field mice (wood mice) are also common in rural and edge-of-town homes, often coming in from gardens and sheds.

Getting rid of mice comes down to three things done together: removing what they come for (food and nesting material), blocking the way in, and making their favourite routes unpleasant so they move on. Poison can work, but it carries risks for pets and wildlife, and mice that die inside walls can leave smells for weeks. That is why many UK households now start with humane, poison-free methods.

Natural deterrents such as long-lasting peppermint, placed along walls, behind appliances and near entry points, help make a home less attractive while you seal gaps. If you see droppings daily, hear activity in several rooms, or have health concerns, a professional pest controller is the right call.

The guides below cover every common situation, from mice in the kitchen, walls or a flat, to home remedies, dead mouse smells and whether mice will ever leave on their own.
