Natural Items To Use To Remove The Smell Of Dead Mouse

White Vinegar

Vinegar smells sour. However, it is a very effective disinfectant that is proven to kill odor-causing germs and bacteria.

What you need to do is place a bowl in the room where the foul odor emanates from the strongest. You should not cover the bowl and just let it sit there for days. The vinegar will evaporate and kill the odor-causing germs and bacteria.

Coffee Filters or Ground Coffee

After your family’s breakfast, you can use the coffee filter pack or the coffee ground from your coffee machine. This is cost-efficient because you did not need to spend anything to make use of an item to get rid of the smell of dead mice in your home.

However, to get results, you should know that the quantity needed to help remove the foul odor could mean twice that your family has used in a day.

Baking Soda

Baking soda is one of the household items that work wonders. This is because baking soda brings the acidic and basic odor molecules into a neutral and odor-free state.

What you have to do is place a few inches of baking soda into shallow bowls. Do not cover them and take them to the area or areas where the dead smell is.

You can also make a baking soda and water solution to spray in the areas where the unpleasant smell is, especially when you cannot be certain where the dead mouse is. It is best to spray two to three times a day for better results.

In just days, the baking soda will absorb the unpleasant smell, and your home will be odor-free. However, for best results, you should combine baking soda and vinegar to scrub down the area where the dead mouse’s body was found. This would make your home cleaner and better-smelling.


Charcoal can remove the odor because of the infusion of oxygen on its surface. The infusion makes the charcoal more porous thus, there is more room that can absorb unpleasant odors. 

It is recommended, however, to purchase activated charcoal in place of the ordinary charcoal.

This is because activated charcoal already went through a heat or chemical treatment, making them extremely porous. It works the same way as ordinary charcoal, but you will expect results from the activated charcoal to be sooner.

Natural Oils

Natural oils like peppermint oil are great in deodorizing areas that have a foul smell. You can also use lemon, rosemary, tea tree oil, lavender, and lemongrass.

Boiling Water With Items That Make Great Scents

Another way is to place great-smelling items in boiling water.

Examples would be orange peels, cinnamon sticks, apple peels, and cloves. This would fill your home with wonderful smells and get rid of the smell of the dead mouse temporarily.


Another natural method you can use to remove the odor of dead mice in your house is by lighting up a candle. The candle should, however, have odor-eliminating properties.

Providing Good Ventilation Is A Must

One more way to neutralize or remove the dead mouse’s odor from your home is by letting some fresh air in. It is best to open as many windows and airways as possible for the longest time you can. This would result in constant air circulation.

If you have a fan, you can also use that and help with the circulation of the air.

Why Does A Dead Mouse Smell So Bad?

Dead mice begin to smell unpleasant when the decomposition of their body begins. The decomposition could take a few days or longer, depending on the size of the mouse or the environment’s conditions where it died.

Accordingly, the decomposition will break down the mouse’s tissue, and because there are different stages of the process, there will be some gases produced.

These gases include methane, hydrocarbons, and sulfur dioxide. When these gases mix, that’s what causes the pungent odor coming from the mouse’s decomposing body.

Things To Do Before Starting To Deodorize Your Home

Before you use the above-mentioned household items to deodorize your home, there are a few steps you have to do. This is to ensure that you are deodorizing the proper area instead of wasting your time and effort.

First, you have to locate the area where the dead mouse is. There’s a good chance the mouse is inside your walls or in places where not anyone in the family frequent.

You should be successful in finishing this step by using your nose. You should smell the wall by placing your nose at least an inch away from it so you can successfully detect the area with the strongest odor. 

Then, you have to remove the items that might absorb odor from the place where the stench is coming from.

These items include fabrics like clothes, upholstery, shoes, books, magazines, mats, rugs, and the like.

If you do not remove these, there’s a possibility that the smell will continue to stink up your home even if you have already deodorized the place where the dead mouse was found and after you take the carcass out.

Next, you have to remove the carcass. It would defeat the purpose of deodorizing if you will leave the carcass of the mouse inside your home.

Put on some gloves and place it in a bag, then seal it. Place it in another bag and seal it again.

Finally, you can apply the home-made or natural remedies to remove the smell from the area where the dead mouse’s body was found.

Never Use Air Freshener To Mask The Smell Of Dead Mice

As earlier stated, one of the most common mistakes and misconceptions when removing the smell of a dead mouse in the house is by using air fresheners.

Experts claim that using air fresheners will most likely make the smell worse because the chemicals from the air freshener would mix with the chemicals from the mouse’s decomposing body.

The smell will most likely make your home smell more unbearable. 

Prevent The Possibility Of Your Home Smelling Like Dead Mouse Again In The Future

To stop the possibility of your home smelling like a dead mouse again, you have to make sure that mice can no longer get inside your home.

Some of the tips that you can follow are to check the outside walls of your house.

See if there are cracks where mice can squeeze themselves through. Another is to check your windows and doors and be sure they do not have big enough spaces for mice to go through. 

You may also call for professional help in case you need their help to ensure that mice would never get inside your home again.
