Where they live

The house mouse can be found in a wide range of urban and rural buildings, although it may live for part of the year outdoors. Mice live in nests, which are often built inside houses, especially during the winter. Nests are built wherever there is access to a good source of food. Spaces under the floor and lofts are favoured places for nests, which are built out of cloth, wool and paper. They are mainly active at night and can be heard running about as they search for food.

What they eat

Their favourite foods are cereal products, although they will eat almost anything. Most of the damage they do is by gnawing and ripping open packets.

Why they are pests

Mice eat and can contaminate all types of food with diseases that they carry, which are hazardous to humans. They can damage and destroy property.

How to tell if your house is infested with mice

Signs of a mouse infestation can include the presence of droppings, footprints in damp soil or dust, and burrows in the ground. Indications of an infestation can include signs of gnawing.

How to prevent an infestation

Ensure all waste, especially food waste, is disposed of promptly and appropriately or stored in sealed containers, including compost bins. Stored materials should ideally be at least 18 inches off the ground to make access harder and identification of an infestation easier. Pet foods and other food products should not be stored in accessible areas such as garages and sheds. Kitchens should be kept clear of spilled food and no food should be left out but should be stored in a suitable container. Keep your property in good repair and close or fill any possible entry holes.
