How to eliminate mouse urine odor

Updated April 17, 2017

No one likes the odour of mouse urine. In fact, getting rid of the urine smell left by mice sometimes can be even more difficult than trapping the mouse itself. Mice communicate by smell and have been known to urinate frequently. As a result, many people have the problem of mouse urine odour after mice are disposed of or if they own pet mice. Fortunately, there are ways to make your house start smelling fresh again.

Clean your mouse cage often if you keep mice as pets. Clean the cage at least once a week with warm, soapy water. Mice communicate with their scent, so you'll also be doing your mouse a favour by keeping the cage tidy and clean.

Get rid of dirty bedding. Often times, dirty bedding can smell bad unless the cage is cleaned. Change the bedding every other day to decrease ammonia and get rid of mouse odour.

Wash the toys and furniture in the mouse cage weekly. Dirty toys and furniture can contribute to bad urine odour. Keeping these things clean will help the overall mouse cage to smell fresh.

Buy an empty spray bottle locally or you can use a spray bottle that you previously used for cleaning. In the spray bottle, combine water, vinegar, and a tablespoon of baking soda. Twist the top on tightly before using the bottle. Vinegar and baking soda work well when getting rid of urine odours. Spray areas of the house infected with unwanted mice and droppings. Depending on how bad your mouse situation is, you may need to repeatedly spray this solution every few hours.

Open the windows to get rid of mouse urine odours. Depending on the time of year, fresh air from the outside does a wonderful job of eliminating odours. However, be careful when opening your windows. Some locations, such as cities, may not have clean outside air, so you may be better off with the windows shut.

Use air purifiers for odour control. Air purifiers are pretty much like fans and filter air from the room. When purchasing an air purifier, make sure it has a HEPA filter and carbon or zeolite filter to make the most out of your odour removal. These filters will get rid of free molecule and particulate odours. The purifier you choose should get rid of odours in the whole room.
