How to Clean Mice Urine


Mouse urine is unsanitary and unsafe, because it can contain hantaviruses. Hantaviruses are directly responsible for Hantavirus Pulmonary Syndrome, a serious disease that kills one in three people who are diagnosed with it, according to the Washington State Department of Health. To prevent contamination, clean up urine of mice as soon as you recognize its presence in your surroundings. Wear gloves and protective clothing while cleaning mouse urine.

  • Launder any fabrics and bedding with mouse urine using hot water and your regular detergent. Verify that your clothes dryer reaches at least 115 degrees Fahrenheit. Dry the clothes in the clothes dryer, if it does. Hang the clothes on a clothesline outside for at least four days, if it does not.

  • Create a mixture that contains 1.5 cups bleach and 1 gallon of water. Fill a spray bottle with this mixture. Spray the area covered in mouse urine with the bleach and water mixture until the area is soaked. Allow it to sit for 10 minutes.

  • Set a paper towel down over the area and allow it to absorb the excess moisture. Place the paper towels in a trash bag and seal the bag.

  • Wipe down the surrounding areas with the water and bleach mixture created in Step 2 with a paper towel. Assume that everywhere around the mouse urine spot is contaminated, as mice often leak urine while traveling. Throw the paper towel in a trash bag and seal the bag.

  • Place the plastic bags in a trash can that is regularly emptied. Make sure the trash can is tightly sealed.

Tips & Warnings

  • Some items, such as papers and books, cannot be sprayed with bleach. For these instances, the Center for Disease Control and Prevention suggests setting the items covered in mouse urine outside, in direct sunlight. Leave them there for a week to inactivate any hantaviruses.
  • For added safety, wash your gloves with soap and water before removing them. Wash your hands again after removing the gloves.
