When you find out you’ve got mice, it’s probably a sickening realization. Not only do they chew through wiring and fabric, they carry diseases like the Hantavirus and Rat-Bite Fever. Even just their droppings can expose to you these illnesses. They also reproduce at a fast rate, and your problem can go from one mouse to an infestation of them before you know it. So what do you do? There are different poisons you can go out and buy, traps that will kill or capture them, and of course, you can always use cats. But what about some DIY solutions? There are many do-it-yourself options out there, one of them being bleach.

What Do Mice Think About the Smell?

Most of you have used bleach in some capacity, whether it’s cleaning or laundry. And if you’ve been exposed to it for even a small amount of time, you know how unpleasant it is. The smell is strong and the fumes sting your eyes. If you touch it, it can quickly burn your skin.

Mice can’t stand the smell of bleach.

The stench of bleach is a powerful one. Humans can’t stand it for very long, and so neither can mice. If they smell it, it will be so off-putting to them, they’ll avoid it.

Bleach isn’t the only thing that’s unappealing to rodents. Other scents will turn them away just as quickly. So what smells do mice hate? Find out here.

Using Bleach as a Repellent

Because the smell of bleach is so undesirable to rodents, it makes a great repellent. You’ll want to mix it with water so as not to create too much of a stench for your home, then spray in any areas you suspect mice activity. Bleach sprayLeave an exit untouched, though, so that the mice can escape your house. If you spray all corners and pathways and leave no clear place to leave, they’ll stay longer.

Something else useful about spraying it around the areas mice have been the disinfectant properties bleach has. Since it is so caustic, bleach destroys harmful bacteria and viruses on surfaces. Considering mice carry disease, it’s helpful to have bleach around to get rid of any microbes you’d find in mice droppings, urine, and blood.

Don’t want to use harsh chemicals in your pest control? Go the natural route. More information on natural mouse repellent can be found here.

A Deadly Weapon

Bleach and dead mouseBleach is useful in many ways, but it can also be deadly in high concentrations, using chlorine as its main component in varying forms. And a person or animal doesn’t have to just drink bleach to be harmed by it. Inhalation causes damage, as well.

Since bleach is a very caustic substance, it can do damage not only on your body but on your belongings, as well. When you spray it as a repellent, it can break down the finish on your wood floors or furniture, stain fabric, and even the paint on your wall. Make sure you dilute the bleach before you spray it, and test it on an inconspicuous area before you apply.

Two things happen when you inhale bleach for too long:

  1. Particles in the fumes come in contact with your nose, esophagus, and lungs.
  2. The bleach breaks double bonds in cells’ of the soft tissue, destroying it and causing many problems like bleeding and decreased oxygen intake.

There’s more than one smell that mice don’t like. Peppermint is one of them, and probably the most well known. But does cedar repel mice? Learn more here.

If bleach comes into contact with your stomach or skin, the following takes place:

  • Epithelial cells start to break down, similar to a burn.
  • If bleach continues to go deeper, it will break down inner tissue and fat, as well.

So how do you use bleach in pest control? While it’s not so hard to use it as a repellent, it’s a little harder as a deadly poison. But there are things you can try.

There are different forms of pest control you can use with mice. Pellets, bait, traps, to name a few. But what about spray? More details on spray for mice can be found here.

How can I get mice to get close to bleach?

Since the smell of bleach is so strong and unpleasant, it’s very hard to hide. A mouse most certainly won’t just come up and drink bleach like water, so you’d have to mask it somehow, and peanut butter is probably your best bet.

Peanut butter has a strong smell and is one of the tastiest substances out there for mice.

  • Take a tablespoon of it and mix in just a little bit of bleach at a time. If you can smell the bleach more than the peanut butter, there’s too much.
  • You could mix in some powdered peanut butter to both keep it from getting too runny after adding the bleach and to also keep the peanut smell strong.

Bleach and peanut butter

If you’re lucky enough that your mice take the bait and eat it, the bleach will kill them, but only if they’ve ingested enough of it. And it won’t be immediate; it could take a day or two.

If you’re dealing with mice and want to try something different, bleach is one way you could go. And if the mice won’t eat it as you want, then don’t worry – at the very least, you’ll disinfect the house anywhere you spray it as a repellent. The beauty of DIY pest control is that you can always move on to another idea right away if the first doesn’t work exactly how you’d planned.

When I empted it out to clean it was weird, the mice had not gotten into any food items. Nope didn’t chew thru a thing! Nothing!! Not even rice!! So Why are they getting in there?.Just to poop?

  12. Use peanut butter and mix some bleach and sugar and put in place where the mice come in at also put some steel pad in the hole also if you can get some mice or rat repellent to spray around the area it be good or bleach and water around the house outside would help also

  13. It’s funny to read these comments as most of us who have an apartment / house HATE TO SEE THESE THINGS OR SEE SIGNS that they are actually in our dwelling!!!! I too am up all night, sleeping with all the lights on. Something I’m finding also (which a couple of people mentioned) is that they don’t want my food in the cabinet (rice, crackers, raisins), this little fool has brought in food from somewhere (I’m a vegetarian and the food I found on the floor the other day was meat) else. Also, the droppings are very small – like the size of pepper so I assumed these were roach droppings even though I have never seen a roach until I saw the piece of meat the other morning on the floor. I too bleach everything and I’m constantly looking for signs or listening for noises. I HATE these things and have never had one enter my dwelling so am I scared of them I also want to kill them (sorry, I’m not going to be humane in this situation). I’ve set 2 snap traps and some bait box around the dwelling inside and I have placed 3 glue traps too. I just read last night fox urine will deter them as they think it’s preditor. Oh, I also bought some steel wool and put around the flooring that had gaps (the landlord redid floors and there are gaps at each one). I really dont know where they are getting in as all the sink holes are sealed. The small different shaped droppings (they look like pepper) is what is throwing me off. I’m not sure how effective the peppermint oil smell is and if it is effective how long before they become familiar with the smell. Those sonic plug in do not work, so don’t waste your money. Regarding the traps, people say mice like peanut butter and that may be true for some, but I keep reading that mice also like chocolate that might be an option to use in the traps if they are passing up on the PB.

    I HATE THESE THINGS SO MUCH THAT I WANT TO CATCH THEM, POUR LIGHTER FLUID ON THEM, THEN LIGHT A MATCH AND WATCH THEM BURN!!!!!

  14. Your comments echo how l am feeling now l have 7 Humane traps nothing works ,l put a camera on the floor l have proof the mouse just sits there looking at one of the traps .Peanut butter,cake,chocolate,bird seed,dog food etc nothing entices these mice.l have OCD so l feel the place is dirty all the time now which it is .This mouse literally poops everywhere.l do have clutter as my mother was a Clean hoarder which l have tried to deal with .Just found poop in the attic l want to cry.l need help

  15. Rosa, I feel your frustration, I want to hurt kill them, I’m sorry for those who are humane. I once called this place home, i can’t sleep, eat, concentrate nothing. Im getting a cat, I’m buying bleach, I have traps every where they avoid them like the plague, they make churping sounds day and night, I can’t sleep. Terminex has come here and said your house is clean I can only suggest you wrip out the heaters so I did that and put steel wool in them, now they can’t leave, I’m going insane, I even put black pepper along the floor boards. Im at the point I just want to shoot then with a bb gun.

  16. Going to try some 99% granules (pool sanitizer) on newspapers around the motorcycle they have just found. Barn type environment so no way to close it up. Thanks for setting the gears in motion to solve an issue. Caution this stuff is extremely toxic, handle with extreme care. glove up. Using newspaper so I do not damage the concrete.

  17. Attic full of mouse poop.hear scratching noises.left poison up there.they haven’t touched it.bleach and cinnamon oil placed in each room.What happens to the poop does it attract flies

  18. First let me say, I HATE MICE!!!!!! I use to use traps and put peanut butter and cheese on them, but the mice would eat it, but not set traps off, aarrrrggghh. I then decided to use the “unhumane” glue traps. They work wonders..I love them. They don’t kill the mice, but the mice can’t get off. Now I know people will hate me for saying this, but I just chuck the whole trap with the live mouse attached, and put them in a plastic grocery bag and throw it away in outside trash can. I feel no remorse or sentiment in doing this, because I’m rid of the mouse. Yayyyy!!
