Get Rid Of This Nasty Mice Urine Odor

One of the common telltale signs of mice infestation is the strong-smelling urine. Based on my experience dealing with mice, I can describe it in two words – strong and pungent. It smells like strong ammonia that has a distinct smell.

So, when this smell gets into your carpet, furniture, and flooring, it can leave an intense odor that will linger for a long time. That’s why it is essential to know how to get rid of mice urine odor.

To get rid of mice’s urine odor, first, you need to mouse droppings and then dispose of the waste properly. Disinfect the infected area using a solution of bleach and water. The recommended concentration of the bleach solution must be 1 part of bleach to 10 parts of water.

Getting rid of the smell does not need to resort to expensive treatments and toxic chemicals, which can be harmful to your family and pets.

Instead, you can use some of your cleaning agents found in your household. Today I’ll give you a guide on how to clean up and get rid of the strong smell from the mice’s urine.

Here’s How To Eliminate The Urine Smell From Mice

Before anything else, you need to be cautious when cleaning up rodent-infested areas.

Before you clean, make sure you trap the rodents and seal all the possible entryways to ensure that no rodents can get into your house.

Set up traps and poison baits for a week to assure that your place is now free of rodents. If no rodents are captured, the active infestation has been eliminated.

The time that has passed is enough to say that the infectious virus in the urine or droppings found in their nesting place is no longer contagious.

If you are about to begin the clean-up process, ventilate the area by opening all the windows and doors for at least half an hour to allow the fresh air to enter the site.

You may use cross-ventilation and leave the area during the airing out period.

Clean Up Any Mice’s Urine And Droppings

When you begin to clean up, keep in mind that you do not stir up the dust by sweeping or vacuuming up the droppings, urine, and nesting materials. In this way, you’ll prevent the spread of dirt and viruses.

Here are some tips when handling mice’s urine and droppings:

  • When cleaning urine and droppings, make sure to wear rubber, latex, or vinyl gloves to avoid direct contact with it.
  • Spray the urine and droppings with a disinfectant, or you can make a bleach solution from a mixture of 1 part bleach to 10 parts water. Let it soak for at least 5 minutes. You may also use commercial disinfectants like Clorox Clean-Up Disinfectant Cleaner, Diversey Virex All-Purpose Disinfectant Cleaner, and other similar products. Just follow the manufacturer’s instructions on the label for dilution and disinfection time.
  • Use a paper towel to pick up the droppings and wipe the urine. Dispose of the waste in the trash can properly.
  • Once you have removed the rodent droppings and the urine, it is now time for the next step to get rid of the smell of the urine.

Eliminate Smell Of Urine With Bleach Solution

So, you are done with the cleaning process; it’s now time to neutralize the smell. There are two sources where the scent comes from:

  • The surface and materials where the urine is soaked into.
  • The enclosed air in that area.

To eliminate the smell, you need to treat the sources of the odor. And now that you know your two objectives, let’s take a look at the step-by-step process.

Neutralize the odor

It would help if you broke down what are the actual compounds that create the smell.

Well, it can be possibly accomplished using an enzyme solution like the Rocco & Roxie Professional Strength & Odor Remover. Just spray the solution on the area and let it sit for about ten minutes.

Ensure that the solution gets deep down onto the pores of the material to get rid of the urine trapped inside.

Draw out the odor

To eliminate the smell, you may use baking soda or make a baking soda paste by mixing it in water.

Pour the baking soda on the target surface or smear the baking soda paste liberally on the surface, let it sit, and then wait for a day or more before you clean it up.

Optional, you may mix vinegar with the baking soda solution as well for better results.

Freshen up the air

Many household remedies can work very well. The most common tip to get rid of bad smell is to let fresh air come in and out of your house.

To make this happen, just open up all the windows, doors, and if you have fans, turn them on. By doing this, it will help flush out all the stagnant air that contains the foul odor.

Aside from fresh air, here are some household remedies that can help eliminate or at least help in lessening the smell of urine:

  • Baking soda
  • Vinegar
  • Raw onions
  • Coffee grinds
  • Charcoal

Another way to get rid of the strong smell is to use absorbent products. Therefore, here are some of the top-rated products you can try to neutralize the scent:

The process of using these products is just similar to how you use household remedies. Just place one of the bags or products in the room or area that smells.

One bag is sufficient to purify the smell of the room. You may check the instructions to determine how many bags you need.

The last option to eliminate the smell is to use electronic products, but since these are electronic devices, they are more costly and can be dangerous to use if not used properly.

Usually, ozone generators are used by the hotels to get rid of nasty smells. These devices are useful, yet they are expensive and may pose potential harm.

When using these kinds of products, make sure to leave the room for at least two hours after running the machine.

Be careful not to breathe on the gas. Follow the manual instruction on how to operate the device.

Air ionizers effectively get rid of bad smell; however, they work best if they are used as a complementary solution. They filter out the air, but air ionizers are not expected to solely take care of the job.

Disinfect The Whole Area/Room

In cleaning up the infested room, make sure to wear gloves so that you will not get in contact with left dirt, viruses from the mice’s urine, and droppings.

  • Mop the floors and wipe down the countertops with a disinfectant or use a bleach solution. (1 part bleach and ten parts water)
  • Check your upholstered furniture and carpets if they have evidence of rodent exposure. You may steam clean or shampoo them to get rid of the smell and dirt.
  • If your beddings and clothing are exposed to rodents’ urine and droppings, wash them using a laundry detergent in hot water.

Once you are done cleaning, remove the gloves and wash your hands with soap thoroughly, or you may use a waterless alcohol-based hand rub when soap is not available or you don’t have access to the sink.

Remove Dead Rodents Or Nests

Wear rubber, latex, or vinyl gloves when dealing with dead rodents and nesting materials.

  • Spray the dead rodents or nests and the area surrounding the infected place with a disinfectant or a mixture of bleach and water.
  • Soak the rodent, nesting materials, and droppings in the solution for at least five to ten minutes before wiping it up with a paper towel or rag.
  • Place the dead rodents and nesting materials in a plastic bag and then seal tightly. Place the bag in another plastic bag and then close it properly.
  • Throw the plastic bag in a covered trash can that is regularly emptied.

After you are done, always wash your hand with soap and water or use a waterless alcohol-based hand rub when soap and water are not available.

Getting Rid Of The Mice Smell In Attic & Basement

It takes a lot of work to clean the infestation in the hidden areas of your house, such as the attics, basement, wall cavities, and crawl spaces since these are the areas where mice love to dwell.

But before you clean nesting remnants like droppings and urine, you need to trap them first.

To do this, you may set up some rodent traps in the infested areas.

If the infestation is currently active, you may catch them quickly. If five days have passed with no new captures, most probably, you have eliminated the population.

Before you disinfect the crawl space, attic, and wall cavity, have it ventilated for at least half an hour to clear contaminations and smell. You may use fans to ventilate such stuffy areas.

Here are some tips when cleaning attics, basements, crawlspaces, and storage areas:

  • When dealing with mice’s urine, droppings, and nesting materials, make sure to rubber, vinyl, or latex gloves. You may also wear a mask to protect you from inhaling particles-containing viruses.

Note: Dust mask may protect you against dust, molds, and insulation fibers but will not protect you from viruses.

  • Spray urine, droppings, and nesting materials using bleach solution or a household disinfectant. Just follow the instruction about the dilution and disinfection time. Soak them well so that it will inactivate any viruses lingering in the area. Use a paper towel or rag to pick the materials and dispose of them properly in the trash can.
  • After spraying the area with a bleach solution or disinfectant, mop the floors. You may also use to spray bleach solution or disinfectant to clean dirty floors.
  • If the insulation has been contaminated with urine and droppings, it should be placed into plastic bags, seal them tightly, and properly dispose of them.
  • If you suspect that your stuff is contaminated in your storage boxes or containers, you need to move them first outside and place them in an area that is well-ventilated and is exposed to direct sunlight. The outside covering of the storage box or container can be disinfected using a bleach solution or your household disinfectant.

Then, remove the suspected contaminated materials while in the sunlight and ventilated area.

Remain upwind so that the dust and debris may not be flown toward your face. If the contaminated items are washable, such as clothing and furniture, wash them using a bleach solution.

But, if your storage boxes just contain the old clothes that you no longer use, it is best if you just discard them.

  • Recyclable materials such as bottles, cans, and plastic containers can be disinfected with bleach solution. Using a paper towel or rag, wipe up the urine and droppings, and dispose of the waste properly.
  • Make sure to clean the countertops, drawers, gloves with disinfectant or bleach solution. Lastly, decontaminate the gloves with a disinfectant and wash your hands with soap and water.

Inspect the walls, ducts, gaps, cracks, and other possible rodent entryways to prevent further infestation in your storage areas.

Cover these openings with mesh wires or sealants.

Consider paving the crawl spaces under the structure.

Eliminating Smell Of Mice Urine In Your Car

One of the worst experiences you can deal with mice is when you head out of your garage, get in your car, and smell the unmistakable strong odor of mice.

What you are smelling is the urine that has been deposited all over the seats and carpet.

Since this is urine from a mouse, the smell will not go away soon, even if you manage to get rid of the mouse in your car.

Getting rid of the smell inside your car is daunting, and half-measures will not take it away. You cannot sprinkle some carpet-fresh around or hang-in car freshener, then mask the smell and expect good results.

Here are some tips to get rid of mice’ urine smell in your car.

Remember Safety Measures And Avoid Getting Sick

Mice’s droppings and urine may contain Hantavirus.

So, before you deal with such waste, make sure to wear your protective safety gear like gloves, goggles, and respirator if possible. Dispose of any droppings and nesting materials you find in your car.

Pull Out The Car Interior [Carpet]

Begin by getting everything out of the car, right down to your sheet metal and fiberglass. The carpet pad is the most important since all the spilled liquid will eventually go down to your pad.

To do this, you need to pull out the seats, then your carpet. It needs to come out of the car to get rid of the odor.

Do this task carefully, because you can put it back in when you are done, especially if you don’t want to buy a new carpet for your car.

Search And Destroy Mouse Nest

The next step you need to do is to get into your dashboard and firewall.

The stealth nest is often a big fluffy bed that lies down right on top of the heater core. That little radiator offers nice and cozy spots for mice having excellent access to the outside world.

Among other places where mice build their nest is on the heater fan or the A/C unit. Regardless, you don’t eradicate the source; you will trigger the mouse every time you use your climate control system.

Also, look for chewed wirings. Mice love to chew on wirings, and they will shred fiber-based carpet pads to build up their nests.

Clean Everything With Nature’s Miracle

Mouse’s urine soaks into the carpet and underneath the carpet pad. Luckily, carpet pads are cheap, and you can easily replace them.

You may clean it yourself, or if you are not comfortable doing it, you can have your carpet steam-cleaned in a shop. They can give you the rest of the interior an excellent cleaning.

You may a product called Nature’s Miracle that contains enzymes that breaks down odor-causing molecules. You need to soak this product in, so it is best if the carpet is out of the car when you use it.

Once you are done, hang your carpet outside in direct sunlight and fresh air so that it will dry for a couple of days.

Then, please put it in a small box or plastic bag for a day and let it get warm. If it still smells bad, it’s now time to replace and buy a new carpet pad.

If you also see signs of mice infestation in your dashboard, you need to clean the area. If the nest is on your heater core, you need to scrub it down with cleansers to get the dried urine out of the core surfaces.

You may also buy an ozone generator and put that in your car. These devices eliminate foul odors from the air, but they do not go deeper into the root of the problem, which is in your carpet and seats under the dash.


Due to the infectious viruses rodents bring, it is essential to exercise caution when cleaning and getting rid of their urine, droppings, and nests from an infested area. Mice’s urine has a strong, distinctive smell that can be bothersome if left uncleaned, so make sure to clean the contaminated area with a disinfectant or bleach solution, and do not forget to wear your protective gear when handling mice.
