House Mouse

house mouse

The house mouse is one of the most common and problematic rodents in the nation. They can survive anywhere food and warm shelter can be found, often infesting homes, farms, and commercial properties.

House mice are small with dusky gray fur, protruding black eyes, large ears, and nearly hairless tails. Grains and seeds are their preferred food source, but they will also sample foods high in fat, protein, and sugars. Such foods include bacon, peanut butter, nuts, chocolate, and even dog food.

These little critters are notorious nibblers, discarding partially eaten food and destroying more food than they actually consume.


House mice not only consume foods meant for humans, pets, and livestock, they can also contaminate it. Although not noticeable to the human eye, they never stop urinating and leave trails of urine wherever they go.

Through their urine and feces, house mice can spread a number of diseases including salmonellosis, a form of food poisoning. Their fur and waste can also cause health problems such as allergies and asthma.


House mice can cause extensive damage to structures, insulation, personal belongings, and vehicles by their nesting and gnawing habits. Since their teeth never stop growing, they will chew on various items to keep their teeth filed down.

Often times they will nest in large electrical appliances where they may gnaw on wiring and insulation. This can result in costly repairs and is a potential fire hazard. According to the National Pest Management Association, it’s estimated the #1 reason of unexplained house fires in the United States is caused by rodents gnawing wires.


The most common indication of a house mouse infestation is finding their droppings. Other evidence includes gnawed food packages or items, nests, and tracks. Nocturnal by nature, seeing mice during the day usually indicates a high population.
