How to clean mice urine

Updated July 20, 2017

Mouse urine is unsanitary and unsafe, because it can contain viruses. Mice naturally head for food storage and preparation areas. To prevent contamination, clean up mice urine as soon as you detect its presence in your surroundings. Wear gloves and protective clothing while cleaning up the mess.

Machine wash any fabrics and bedding with mouse urine using hot water and your regular powder. Verify that your clothes washer-dryer reaches at least 50C. Dry the clothes in the clothes dryer, if it does. Hang the clothes on a washing line outside for at least four days, if it does not.

Create a mixture that contains 1.5 cups bleach and 4.5 litres 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.

Place a paper towel over the area and allow it to absorb the excess moisture. Place the paper towels in a bin bag and seal the bag.

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

Place the plastic bags in a bin that is regularly emptied. Make sure the bin lid is closed securely.


Some items, such as papers and books, cannot be sprayed with bleach. In this situation, place the items covered in mouse urine outside, in direct sunlight. Leave them there for a week to inactivate any viruses.

For added safety, wash your gloves with soap and water before removing them. Wash your hands again after removing the gloves.
