How dangerous are mice?

Fall is the season when mice have good reason to seek refuge indoors. While they may appear harmless, these tiny rodents can bring about a host of problems and pose potential dangers to health and your home or business. How dangerous are mice?Here are some of the threats that mice present and what you can do about them.

Damage to furniture and appliances

One of the most common issues associated with mice invading your home or business is the damage they can cause. Mice have a habit of gnawing on various materials, including wood, plastic, and electrical wires. When mice chew on electrical wiring, it can create the risk of electrical fires. The exposed wires can spark or short, causing a potentially catastrophic situation.


Mice can carry harmful pathogens on their bodies and in their feces; one of the most concerning bacteria being Salmonella. This bacterium is known to cause food poisoning, leading to symptoms such as diarrhea, fever, and abdominal cramps. Salmonella can be particularly dangerous for young children, the elderly, and individuals with weakened immune systems.

If mice contact food sources or food preparation areas, they can transfer Salmonella and other pathogens, contaminating food, drinks, appliances, furniture, and food preparation surfaces.


Hantavirus is another grave concern associated with mice infestations. This virus can be transmitted to humans through contact with mouse droppings, urine, or saliva. The symptoms of hantavirus infection can range from fever, muscle aches and fatigue to more severe respiratory issues. In some cases, it can even be fatal.

Hantavirus is particularly concerning because it can be challenging to diagnose in its early stages, often resembling common flu symptoms. Therefore, if you suspect a mouse infestation in your home or business, it’s crucial to take it seriously and address it promptly to prevent any potential exposure to this deadly virus.

Preventing mouse invasions

The best way to prevent mice from entering your home or business is to seal up any cracks or holes on the outside of the structure. Mice are excellent climbers. Potential entry points could be in places such as the foundation, walls, doors, around vents, and where utilities enter. You should also keep your home and business clean and free of clutter, as mice are attracted to food, materials to use in their nests, and places to nest. If you do see mice in your home or business, call a pest control professional immediately. Here are some additional tips to help prevent mice:

  • Store human food and animal feed in tough, sealed containers
  • Clean up any food spills or messes immediately, and cover and remove garbage frequently
  • Install weatherstripping around doors and windows
  • Mice need food and shelter; look for potential sources in the surrounding area outdoors where they may be coming from
  • Use mouse traps or bait stations to control them before or as they enter structures
