Desperate times call for desperate measures. When you have a mouse infestation, you may be tempted to try some unique approaches to keeping them away. That means trying to repel mice with smells that they hate. A common question that people ask is, does bleach really repel mice? Read on to discover whether you can rely on bleach to help you get rid of your mouse problem.
Why You Need to Keep Mice Away from Your Home
You may have read the title and wondered why someone would be so desperate as to use bleach to keep mice away from their home. Such drastic steps are warranted, though. After all, mice are not just a nuisance that eat your food and leave droppings everywhere.
For one thing, mice can infect humans with some serious diseases. Although mice carry rabies, it’s extraordinarily rare that it spreads to humans, if ever. Yet, mice can also carry hantavirus and hemorrhagic fever, to name a few of the most dangerous viruses.

Mice will ruin your food as well. While that is annoying and costly, you should be more worried about their propensity for chewing wires and electrical cords. This can cause power failures, appliance or electronics malfunctions, and even electrical fires.
The average mouse nest contains between 2 and 6 mice, and they breed fast. Mice only require 21 days to birth a litter, and the mice can then breed after only being alive for 6 weeks. That being the case, it’s imperative to get mice out of your house using whatever you have in your power. Otherwise, you can be overrun. So, let’s get back to the original question.
Does Bleach Really Repel Mice?
Yes, bleach will repel mice, but it’s not the product that you want to use to get the job done. Bleach has a powerful and unpleasant smell, which will keep mice away in the short term. However, that smell doesn’t remain long without a great deal of the product being applied.
As a result, you would need to spray or pour a large amount of bleach to maintain an environment that would repel mice. So, the question is no longer “does bleach really repel mice,” it is “should you use bleach to repel mice.”
In most situations, the answer is no. You probably should not count on bleach to be your primary tool in getting mice to stay out of a building. If you used enough bleach to keep mice away from your home, you would probably want to move out yourself.

Bleach is not a pleasant smell on its own to most people. Moreover, breathing in bleach fumes, spilling it on your skin, or inadvertently mixing bleach with other chemicals in your home can prove very harmful. This is especially true of households with children.
Whether you are spraying a bleach mixture or leaving cotton balls soaked in bleach in areas of your home, you may be harming yourself more than the mice. After all, mice hate many other smells that are not as harmful to humans. There are also other ways of getting mice to stay out of your home.
What Other Smells Do Mice Hate?
There are a variety of scents that you can use to repel mice without endangering yourself. For example, peppermint oil is one of the most popular scents that people use to send mice scurrying away. If you’ve ever had overly minty tea, then you know the burning sensation that fills your nose when something contains too much mint. That’s the same idea behind using peppermint oil to ward off mice. In fact, you can find premixed peppermint essential oils that you can spray in places where you think mice are likely to hide.
However, you would only be replacing the smell of bleach with that of mint if you were to use this. It’s not recommended that you fill up your kitchen or bathroom with the smell of mint. It’s far better to take time to identify the ways mice are getting into your home and permanently remove them or relocate them.

That being said, other smells that mice don’t like include:
- Cayenne pepper
- Ammonia (reminds them of the urine of their predators)
- Dryer sheets
- Clove
- Chili powder
- Cinnamon
- Vinegar
You can find a wide variety of ways to use these smells to keep mice from getting into your home. Some people insist on keeping dryer sheets in their cabinets while others have made peppery mixtures that they spray around the outside of their homes. The bottom line is that if you’re looking for smells to keep mice away, all of these are safer than bleach.
Bleach Plays a Crucial Role in Cleaning After Mouse Infestations
Although bleach is a noxious chemical, it has a very important use in cleaning after mouse infestations. One of the most important things you must do to solve an infestation is to destroy the mouse nests. After you find the nests that mice have built in your home, you need to dispose of them.
- First, put on a pair of rubber gloves and a mask.
- Never sweep or vacuum the dry droppings and urine, as this can can spread dangerous airborne viruses and bacteria.
- Soak the nest, surrounding droppings, and any dead rodents with a bleach solution of 1.5 cups of bleach for each gallon of water.
- Put the sprayed nest, droppings, or rodent in a plastic bag and seal it. Then place that bag into a second bag and seal it. Finally, dispose of the bags in an outside trash bin.
Bleach can help you thoroughly clean up the mess left around the nest. Moreover, it helps you do away with the nasty scents that are left by the mice. Bleach also dissuades other mice from setting up shop in the same area for a little while.
Does bleach really repel mice? Yes, but that doesn’t mean you should use it for that purpose. It’s a far better idea to properly seal up your house and prevent mice from getting inside. That way, you don’t have to negatively impact your health for the sake of keeping pests out.

Instead of relying on bleach, it’s best to properly seal up your house to prevent mice from getting inside.
