How to Eliminate the Odor of Mouse Urine

Quck answer

Mice urine can leave a strong and unpleasant smell in your home. To get rid of the urine smell from mice, follow these steps:

1. Locate the affected areas: Look for areas where mice have urinated, such as corners, walls, or furniture.

2. Clean the area: Mix a solution of equal parts water and white vinegar. Use a cloth or sponge to scrub the affected area thoroughly. Vinegar helps neutralize the smell.

3. Use baking soda: Sprinkle baking soda on the cleaned area. Leave it overnight to absorb any remaining odor. Vacuum the area the next day.

4. Air out the space: Open windows or use fans to circulate fresh air and help eliminate the smell.

5. Prevent future infestations: Seal any entry points to prevent mice from entering your home.

By following these steps, you can effectively remove the urine smell from mice and create a fresh and odor-free environment in your home.


The smell of mouse urine can be quite strong. If it seeps into carpets, furniture, or wood floors, it can leave a lingering, intense odor throughout the room. Fortunately, there are ways to get rid of the smell without resorting to expensive treatments or toxic chemicals that you may not want to use in your home or your pet mouse’s cage.

Step 1

If you don’t already have one, rent a carpet steamer. These can be rented from building supply stores for around $30 per day. Add carpet shampoo to the steamer and follow the instructions for use. Make sure to empty the water container as it fills up. If the smell is particularly strong, go over the carpet a few times.

Step 2

Create a solution by mixing equal parts white vinegar and water. Add a few drops of essential oil, such as eucalyptus or lemon. Shake the bottle to mix the ingredients and then spray the solution onto the area with the unpleasant odor. Allow the solution to sit for a while, but don’t let it dry out completely.

Step 3

Cover the affected area with baking soda and rub it into the damp carpet or rug over the vinegar solution. Alternatively, you can add one or two tablespoons of baking soda directly to the water and vinegar mixture in the spray bottle. If you’re treating a wood floor, mix the baking soda in the spray bottle with the water and vinegar instead of rubbing it into the floor. Spray the solution onto the floor and leave it for a couple of hours before wiping it up. Once dry, vacuum the rug or carpet. Use the baking soda and vinegar solution to clean your mouse cage once a week. Allow it to dry before adding clean bedding material.

Step 4

If the smell persists after the baking soda and vinegar treatment, create a mixture of dish soap (slightly over a teaspoon) and 7 fluid ounces of 3% hydrogen peroxide. Rub this mixture into the carpet or rug while the baking soda is still damp. Applying it onto the baking soda will make it easier to remove later, as the dry baking soda will act as an absorbent.

Step 5

If the odor problem was especially bad, steam clean the area after allowing it to soak in the baking soda and vinegar mixture for a while. If not, simply wait for the area to dry and then vacuum it thoroughly.

Step 6

Wait a couple of days to see if the urine smell has dissipated. If it’s still present, you may need to repeat the process.
