The effects of field mice getting in your home

Field mice often enter homes at the end of the summer to build their nests and stay safe during the winter. These unwanted guests can cause a great deal of trouble in a home and they are not safe roommates. Understanding the damage field mice can cause in a home is critical.


Field mice can cause several diseases and some of them can be transmitted to humans. The most common disease that humans can get from a field mouse is the hanta virus. This is contracted when exposed to infected mouse urine or fecal matter. The disease enters through the lungs and cause hemorrhagic internal bleeding and shuts down the organs. There is no actual cure for the hanta virus, although some patients survive with antibiotic treatment.


Field mice can cause extensive damage to a home and your belongings. For example, if you have boxes of clothes and stored items, field mice in your home will see these as ideal places to build a nest and have a snack. They will chew on our belongings and urinate and defecate on them as well. Field mice can also chew holes in woodwork and walls and cause a large amount of damage, considering their overall small size.

Electrical Shorts

Many house fires are started every year due to electrical shorts, caused in part by field mice nibbling on wires. Mice are voracious eaters and will chew on literally anything they can get their teeth on. Wires are no exception. In fact, they are drawn to the plastic coating on electric wires. They will nibble on an area during the night, and the next morning when you turn a light on, the wire can short, potentially causing a fire. Even if a fire does not occur, the cost to rewire a home can be quite high.

Secondary Problems

Field mice can invade a home and make life miserable for its inhabitants. They steal food, socking it away in dark corners where it can mould and begin to smell. If they eat your food the entire box must be thrown away to avoid contamination. In addition, if you attempt to poison mice and you have pets such as dogs or cats, your pets may die if they eat a poisoned field mouse.
