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.


One of the most common and widely distributed pests in the world, house mice contaminate food stores, cause property and structural damage, and spread many different kinds of diseases. These rodents have poor eyesight, but heightened senses of smell, touch, and taste to compensate. Because house mice rarely travel outside an area of 10 to 30 feet once they establish nests, they 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 eradicated at any first sign of activity!


  • House mice weigh about 0.5 ounces and grow between 8 and 11 inches long, including tails
  • House mice bodies are covered in light brown to black fur
  • Bellies are typically white in color
  • Pointed noses
  • Tiny black eyes
  • Large ears
  • Scaly tails


Originating from Asia, house mice are now spread to North America and across the world due to international commerce. Now they are found in virtually every part of the world and hold a wide distribution, enjoying wherever there is human activity! House mice may nest underground or in any sheltered location. They may build nests out of paper, burlap, and other fibrous materials in and around houses, farms, warehouses, and open fields.



Are house mice known to enter homes or yards?
Some of the house mouse's favorite places to nest are in and around human homes and manmade structures. Human activity provides mice with their most favorite foods, including cereal, grains, nuts, fruits, plant seeds and roots, meat, and trash! Also, homes with central heating give these rodents warm nesting locations to gather during winter months.


Do house mice harm people or property?
The second most destructive rodent after the rat, house mice almost always cause some kind of damage to property or people where infestations are present! These rodents consume about three grams of food each day, but destroy much more than that due to their nibbling habits. House mice dig up freshly planted crops, gnaw straight through containers of food in warehouses, and even contaminate packages with their urine and droppings.

As they spend a lot of time in dumpsters, sewers and other filthy locations, house mice are often riddled with pathogens and secondary pests. The rodents have the capacity to spread salmonellosis, leptospirosis, rat-bite fever, tapeworms and may carry fleas, ticks, and similar parasites in their fur! Humans can contract diseases from mice by coming into contact with or accidentally consuming their urine and feces.

Also, house mice are capable of serious structural damage. Their teeth grow rapidly, and because of this, they must gnaw to keep the length under control. This leads to 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 guards against house mouse infestations. House mice are very capable pests! Property owners often have to employ multiple techniques to reduce the possibility of attracting the rodents. Some easy ways and helpful activities include cleaning homes regularly, sealing cracks in building foundations, eliminating clutter in basements and attics, keeping food stored in airtight containers, and removing collections of debris or garbage in yards.
