Every winter, rodents get into about 21 million homes in the United States, which can be a bigger problem than just an annoyance. Keeping healthy in the winter is difficult because of the widespread viruses like the flu and the common cold. At this time of year, though, not many people think about the health and property risks that rodents pose.

Mice and rats, among others, seek out the warmth, food, and shelter of our homes throughout the winter months, and they often find their way through the tiniest of openings. The true danger, however, lies in the fact that these pests, once inside, can spread diseases and cause significant property damage.

Dry feces pose health risks to anyone who inhales them. Mice and rat waste can cause an outbreak of disease, pollute food supplies, and set off allergic reactions in humans. In addition, the illnesses and viruses listed below can be transmitted by rat and mouse droppings.

Health Risks with Mice


Rodents, most frequently the white-footed deer mouse, are responsible for the fatal disease hantavirus. The chance of contracting an infection increases if a person is close to a rodent’s active living area and comes into contact with or breathes in infected rodent urine, droppings, or saliva. The Centers for Disease Control and Prevention (CDC) say that the first signs of the disease are tiredness, fever, and sore muscles. 

Other adverse effects include gastrointestinal problems, colds, headaches, and vertigo. Last year, ten people became ill, three died after sleeping in tent cabins in Yosemite National Park and being exposed to the Hantavirus from infected deer mice.

Bubonic Plague

During the Middle Ages, the plague, also called the “Black Death,” killed one-third of Europe’s population. The plague was a highly contagious illness that sometimes killed people. The plague is spread when an infected flea bites a rat or mouse. It causes fever, headaches, and lymph nodes that are very big. In 2012, a young Colorado woman who was camping caught the virus.


Salmonellosis is caused by a bacterium that is usually found in the poop of rodents and can be caught by eating raw or undercooked food. According to WebMD, there are roughly 40,000 cases of Salmonella annually in the country. Symptoms include diarrhea, fever, and stomach pain.

Rat-Bite Fever

Rat-bite fever (RBF) is a dangerous infection that can be spread by biting infected rats or mice or eating food contaminated by rodent waste. The CDC states that in 3–10 days following contact with an infected source, symptoms like fever, vomiting, headaches, rash, and muscle pain usually manifest.

Rats and mice can eat through attic insulation, wallboard, cardboard, wood, and even electrical wiring, which seriously threatens people’s health and property. According to estimates, rodents cause 25% of all home fires in the United States.

Rats have a high rate of reproduction, which means they can quickly go from being a minor annoyance to a serious issue. The best defense against these pests is prevention, so homeowners should prioritize it.
