Does Bleach Repel Mice? 5 Ways It Can Be Used

| | ,

Mice are a nuisance in any household. They wreak havoc by chewing on clothing, wires, furniture, not to mention the likelihood of spreading diseases. Studies show mice carry nearly 27 diseases, including leptospirosis, hantavirus, tularemia, lymphocytic choriomeningitis, among others. Whilst there are some awesome mouse control techniques, there are also some tools you can use to repel mice from entering your home. In this post, we are going to answer the question; does bleach repel mice?

The use of poison or rodenticide is also efficient at eliminating mice, but it can pose a danger to your pets and children. As a result, homeowners opt for more natural methods to keep away rodents. One of them is the use of bleach.

Bleach has a strong, unpleasant smell that stings the eyes, but does bleach repel mice?

Does Bleach Repel Mice

How does bleach repel mice?

Mice have poor eyesight but a strong sense of smell. They use scent markers, also known as pheromones, to detect potential danger and communicate with each other. It explains why mouse traps are baited with cheese, peanut butter, and other foods that release a pleasant smell.

The unpleasant smell of bleach is undesirable to rodents making it an excellent repellant. So how does bleach repel mice?

5 Ways to Use Bleach to Keep Mice Away

1. Spray Areas that Have Extreme Mice Activity

I recommend diluting the solution to avoid creating too much unpleasant smell in your home. Spray the areas you suspect to have mice activity, e.g., pathways and corners. Be sure to leave an exit for them to escape. If you obstruct the exit, the mice are likely to live in your house longer.

The bleach not only repels the mice, but it also destroys disease-causing bacteria and viruses on the surfaces.

The idea is to ensure the mice inhale enough bleach fumes to kill them. When inhaled, the bleach breaks down the cells in the soft tissues causing bleeding and reduced oxygen intake. It has to be a lot though! One lungful of bleach is not enough to kill a mouse.

2. Mix it with Peanut Butter

The strong, pungent smell makes it pretty difficult to conceal it. As such, you need to mask it to bait the mice. Peanut butter has proved a useful masking element as it has a strong smell and is sweet. A tablespoon of peanut butter mixed with bleach should woo the mice.

Ensure the peanut butter masks the pungent bleach smell completely. If you can still smell bleach, there’s probably too much of it in the mixture. You can also mix the bleach with powdered peanut butter as long as it does not become too runny after adding bleach.

Once bleach comes into contact with the rodent’s stomach, it causes epithelial cells to break down just as burns occur. What’s more, if the bleach continues to eat away, the cells, fats, and inner tissues are broken down as well.

The mice should ingest enough peanut butter to kill it. Its death is not immediate and may take 24-48 hours. this is not a humane way of killing a mouse, and whilst it is not something I recommend, it is something that works as part of a mouse control process.

3. Using Cotton Balls Soaked in Bleach

Soak a few cotton balls in diluted bleach and place them in areas where the mice visit frequently. Mice are quick to detect a change in odor and using cotton balls soaked in bleach will effectively drive them away.

Additionally, you can use these soaked cotton balls to distort their trails by placing them along their usual path. This will slow them down, increasing your chances of catching them and disposing of them.

4. Sprinkle Bleach in their Hiding Places

If you have already identified several mice hiding places, then you can sprinkle bleach solution to drive them out. If not, sprinkle baking soda on the floor before sleeping. You are likely to find paw prints that will direct you to their hideouts. The foul-smelling bleach will compel them to leave the hideout in search of a hideout that has fresh air.

Alternatively, you can find, seal and sprinkle bleach in the mice entry points to avoid more mice from entering your home. Inspect the cabinets, closet doors, and the outdoors to identify all the entry points.

Mice get through holes as small as a quarter-inch hence the need to ensure the holes are completely sealed.

After sealing these entry points, you can go ahead and sprinkle bleach solution to effectively repel them.

5. Disinfect the Nests

If you are confident of eliminating the mice, it’s time to clean out their nests to avoid contracting any diseases spread by mice. Avoid vacuuming or sweeping the area as it may cause disease-causing bacteria to spread in the air, causing you and your loved ones to inhale contaminated air.

Also wear protective gear such as latex, rubber or vinyl gloves. Then, spray the nest with a bleach solution and allow it to soak for five minutes.

The recommended ratio of bleach to water is 1:10.

Use a paper towel to collect the dropping and dispose of the waste in a garbage bag.

Make sure to clean up the mouse urine too!

Once the rodent droppings are removed, disinfect the items. Also, clean the countertops and mop the floors using the bleach solution. It would help if you also ventilated the area for an hour by opening the doors and windows. If you have an electric fan, it would be helpful if you switched it on to drive the smell of bleach away.

Frequently Asked Questions

frequently asked questions

Will spraying bleach keep mice away?

Yes – I have found that using bleach will keep mice away. You will need to reapply the bleach products for it to continue to work. Spray the bleach in any place where you have noticed mouse activity. Be careful not to spray the bleach on items that can be damaged!

Does peppermint oil repel mice?

In large doses, peppermint oil will repel mice. You have to use it in localized environments, and you also have to make sure the oil is replaced very often. Using peppermint oil in an open space is not going to work at all, but it will make your home smell better!

What scent will keep mice away?

I would use bleach, pepper, or peppermint oil to keep mice away. It is not enough to use these products, so you must use other mouse control techniques to make sure you win the battle!


Bleach is only useful in repelling the mice from your space; it does not always kill them unless ingested. Getting a mouse to ingest bleach is going to be extremely difficult too!

As such, you need to be proactive at eliminating things that attract the mice to your house.

You can eliminate potential food sources and clean up food debris on countertops and floors, and store leftovers in glass containers with lids. Also, removing climbing sources like trees and vines should help keep mice away. Overgrown vegetation, piles of firewood, long grass, and debris also make potential breeding and hiding areas for mice.

Sealing mouse entry points is the best way to avoid getting mice into your home.

Good luck!
