House mice (Mus domesticus) are well adapted to living in close contact with humans and thrive in the conditions that man provides, particularly where hygiene and house keeping standards are low. They can cause extensive damage to property as a result of their gnawing activities, and also by eating and contaminating food. Mice may carry a number of infectious diseases that can pose a risk to humans and animals. Where problems arise, it is important that house mouse infestations are controlled.
House mice are able to live in almost any available space. They can squeeze through extremely small openings, living and breeding under floors, in cavity walls, ceiling voids and behind skirting boards.
House mice will contaminate the environments in which they live with urine, droppings and hairs. They can carry a wide range of diseases which can be passed on to humans, either by directly contaminating food with droppings and urine or, by contaminating surfaces. In food business premises, contamination of food for human consumption would result in failure to comply with hygiene requirements such as those contained in the Food Safety (General Food Hygiene) Regulations 1995.
They can also cause extensive damage to property. They are capable of gnawing a range of materials. There is a significant risk of fire and electrocution as a result of mice chewing through electric cables and wiring.
