The house mouse is the most successful rodent in adapting to live with people. It is found almost anywhere people are, feeding on human food, sheltering in human structures, and reproducing at a remarkable rate. It is the most troublesome and economically important vertebrate pest, contaminating untold millions of dollars worth of food, damaging possessions, and causing electrical fires with its constant gnawing.


Among the most common pests in the world, house mice contaminate food, cause structural and property damage, and spread disease. These rodents have poor eyesight and heightened senses of smell, touch, and taste to compensate. Since they rarely travel outside an area of 10 to 30 feet once they establish nests, house mice are extremely familiar with their surroundings and notice when baits and strange objects appear in their habitats. As their numbers grow quickly, house mouse infestations must be taken care of at the first sign of activity.

Mice are found in virtually every part of the world and hold a cosmopolitan distribution, enjoying prominence wherever there is human activity. House mice may nest underground or in an otherwise sheltered location. They build their nests out of almost anything they can find including paper, burlap, and other fibrous materials in and around houses, farms, warehouses, and open fields.



Human activity provides mice with their favorite foods, including cereal, grains, nuts, fruits, plant seeds and roots, meat, and trash. Human homes provide a typically comfortable, warm, and plentiful environment for mice. So some of the house mouse's favorite places to nest are, in fact, in and around human homes and manmade structures.


House mice almost always cause damage of some sort, to property or people where infestations are present. They consume about three grams of food which doesn't seem to serious, but it's their nibbling habits that cause the real damage. They dig up freshly planted grains, destroy crops before harvest, gnaw through containers of food, and even contaminate packages with their urine and droppings.

Mice spend a lot of time in places like dumpsters, sewers, and other filthy locations. This also means that house mice are often riddled with pathogens and secondary pests. The rodents have the capacity to spread diseases such as salmonellosis, leptospirosis, rat-bite fever, and tapeworms. Mice are also known to carry fleas, ticks, and similar parasites in their fur. Humans contract diseases from mice by coming into contact with or accidentally consuming their urine and feces.

House mice are also capable of serious structural damage. Their teeth grow rapidly, and they must gnaw to keep the length under control. This leads to the destruction of wall insulation, stored items like books and paintings, and damage to support beams and walls that worsens over time. House mice also chew on electrical wires, which can lead to shorts and even electrical fires.


Control and Safety

Unfortunately, there's no fool-proof method of exclusion that protects against house mouse infestations. Property owners often have to employ multiple techniques to reduce the possibility of attracting the rodents. Cleaning homes regularly, sealing cracks in building foundations, eliminating clutter in attics and basements, keeping food stored in airtight and rodent-proof containers, and removing collections of debris in yards are amongst the more effective prevention methods.
