Why Does My Microwave Smell Like Dead Animal?

Most people find it difficult to imagine how a mouse could get into the microwave, especially if you place a high value on cleanliness. Nevertheless, routine microwave and kitchen cleaning cannot completely exclude the potential that a rodent is trying to enter your microwave from another location.


In a similar vein, mice aren’t necessarily to blame for the foul scent coming from your microwave. It is crucial to comprehend the cause of your microwave’s offensive odor and whether or not a dead animal is truly rotting inside. The following are the main explanations for why your microwave smells like a dead mouse:


Dead Mouse

If your microwave smells like a dead animal, there may be a dead mouse or squirrel. Due to how chilly and gloomy microwave vents are, a lot of animals live there and eventually find their way into the microwave. Small microwaves make it simple to find any dead animals that might be entangled in their gas or electric lines, while larger microwaves make it more difficult.


To locate the trapped dead mouse, you’ll need to poke your head inside the microwave. Get rid of any mice, raccoons, or squirrels you find in the microwave or the vent right once to stop the source of that foul stench.


Decomposing Food Particles

This may not seem likely to explain the offensive odor, but it makes sense. Decomposed food can be the source of foul smells, whether you’ve recently moved into a home or have simply opened your microwave after months.

Mouse Droppings

Mice droppings and dried urine may be the source of an animal-like odour in your microwave, even if nothing is dead inside. Before using any cleaning solution or spray, check your microwave and completely remove these droppings.

After turning off the microwave, leave the peels inside for a while since they continue to ward off unpleasant odors.


Vinegar And Baking Soda

Once the dead animal that has been emitting a nasty odor from your microwave vent has been removed, you can use some basic kitchen products like baking soda and vinegar to eliminate the odors in the following ways:


  • Spray as much white vinegar as you can into the vent after adding it to a spray bottle. Vinegar instantly eliminates any offensive odors.

  • Put some baking soda into the vent immediately to eliminate the unpleasant odors. This is because baking soda is an excellent odor absorber.

  • For the vinegar and baking soda to work swiftly and get rid of the nasty smells as soon as possible, keep a fan on high near the vent.

  • Repeat these methods as often as necessary to completely rid your vent of the smell of a dead animal.


You can also boil some white vinegar in a jar if the odor is particularly strong. Overnight, leave the container in the vent. The steam produced by the boiling vinegar will thoroughly clean the vent.



Lemon is a great option to get rid of a bad smell if it is caused by leftover or decaying food. In a baking bowl, extract the juice of two to three lemons. You can now fill the bowl with water and the lemon pieces. After setting the microwave to 120°C, heat the mixture for around 30 minutes.


Please turn off the mixture after 30 minutes and wait for it to cool. After that, carefully open the microwave door and wipe the interior of the appliance with a delicate microfiber towel. Thanks to the lemon’s benefits, you’ll notice that your microwave is clear of grease and unpleasant odors sooner than anticipated.


Vanilla Extract

Who doesn’t adore vanilla’s delightful aroma? One of the tried-and-true techniques that have been used for a long time is the use of vanilla essence to eliminate bad odors from any kitchen appliance. Simply create a little mixture with 200 milliliters of water and one teaspoon of vanilla extract. Instead of vanilla extract, you can also use 10 drops of vanilla essential oil.


After preheating your microwave to 120 degrees C, you should heat this mixture for about 30 minutes. During the heating process, the water in the vanilla extract evaporates. Therefore you should check the consistency two or three times. If you don’t want to heat in the smelly microwave, dunk a microfiber cloth in a mixture of vanilla essence and water, then wipe the inside of the microwave as often as you like until all the odors are gone.
