How to get rid of a mouse droppings smell

Discovering mouse faeces or urine is unpleasant and disgusting, at best. The presence of mouse droppings in a home or business indicates the presence of rodents. Tiny mouse droppings may seem harmless, but carry disease, germs and bacteria. To get rid of mouse dropping odour you must clean the mouse faeces and urine left behind. Proper cleaning techniques and supplies help get rid of droppings and their accompanying odour, while ensuring the safety of your health.

Put on a pair of gloves and a face mask to protect yourself from coming in direct contact with mouse droppings or inhaling the disease-laden dust. Wear these two pieces of safety equipment until the mouse droppings are removed.

Combine 1 1/2 cups of bleach with 1 gallon of water in a bucket. Fill a large spray bottle with the diluted bleach mixture. Spray the mouse dropping area until it's completely saturated.

Scoop up the mouse droppings with paper towels. Continue to wipe the area until all mouse faeces and urine is removed. Discard the paper towels in a trash bag and seal it.

Soak clean cloths in the bleach solution and wring out excess moisture. Wash the surface where the mouse droppings were cleaned up. Allow the bleach solution to air dry on the surface to deodorise smell and sanitise the area.

Fill a few small bowls with white vinegar. Leave the bowls in the room overnight to further deodorise any residual odour.


Open windows in the room, if possible, to circulate fresh air and help remove odour. Use baking soda on a carpeted area to absorb smell. Disinfectant cleaner can be substituted for bleach to clean and sanitise areas with mouse droppings.
