Monday, November 4, 2019 2:21 PM

House mice are typically dusty gray with cream-colored bellies. Fur color varies from light brown to dark gray depending on the mouse’s location. House mice have four legs and a round shaped body. Their muzzles are pointed, and their ears are large with some hair. House mice range from 2.5 to 3.75 inches long. Their tails are usually 2.75 to 4 inches long.

What Do House Mice Eat?

In nature, mice prefer to eat cereal and seeds, but they will also eat insects, nuts and fruits. Inside structures, mice will consume almost any human food, but prefer grain based products. 

Habits

House mice are very social. They organize themselves in social hierarchies with one male dominating lower-ranking males and a large number of females in a given territory. Mature male mice are socially compatible with related mice, but they are hostile and aggressive towards strangers. The size of a house mouse’s territory varies, but it is frequently no larger than 4-5 feet. The size of the territory varies based on the availability of food and water. They are excellent climbers and can jump up to a foot high; however, they are colorblind and cannot see clearly beyond six inches.  

House mice nibble, eating only small amounts of food at a time. They generally feed at dusk and before dawn, but they may also opt to eat smaller meals in between. 

Habitats

House mice live in structures, but they can survive outdoors, too. House mice prefer to nest in dark, secluded areas and often build nests out of paper products, cotton, packing materials, wall insulation and fabrics. House mice are nocturnal, but they can be spotted in the house during the day. House mice are very inquisitive and tend to curiously investigate changes in their habitats. They will often change their established runways for this reason. 

Threats

House mice can pose serious health threats. House mice can carry diseases and contaminate stored food that they eat in the home. House mice have been implicated in the spread of salmonella through their feces. Humans can become ill by consuming salmonella contaminated food. Symptoms of salmonellosis include diarrhea, fever and abdominal pain. House mice may also spread rat bite fever, although this is uncommon. Humans can catch this bacteria-borne infectious disease through contact with a dead mouse or by consuming food contaminated by mouse feces. Symptoms of rat bite fever may appear between 3 and 10 days after contact with a contaminated mouse and include fever, vomiting, headache, rash and muscle pain.

Micro droplets of mouse urine can cause allergies in children. House mouse feces in the home carries bacteria. Inhaling dust that contains dried feces may cause allergies or asthma flare ups. Furthermore, mice can also bring fleas, mites, ticks and lice into your home. If you suspect that your symptoms are associated with rodent infestation, seek medical attention. Be sure to tell your doctor if you suspect contact with rodents or rodent droppings.
