What Do Mice Hate? 10 Confirmed Items

A mouse infestation is a concern…

They are incredibly destructive and can do severe structural damage by gnawing at wood, building nests, and chewing through electrical wiring.

Oh, and they can also carry diseases!

There is no doubt about it. Mice are dangerous, so you should look to get rid of them ASAP. One way you can achieve that is by finding out what mice hate.

Making your home unlivable (for the mice) is a sure way to get them out. To help you do just that, here’s a list of the things mice are afraid of.

What Do Mice Hate_ 10 Confirmed Items

Do Mice Hate the Following?

1. Cats


Mice absolutely hate cats. It shouldn’t come as a surprise, though, since cats (the predator) like to catch and eat mice (the prey). Having a cat does help to keep mice away.

Studies have shown that mice have evolved receptors that help them detect chemical signals from other animals.

Mice can detect unique proteins in cat saliva, and this instinctively causes them to react in fear.

You can also get rid of mice by using kitty litter.

2. Dogs


Mice hate dogs, but not as much as they hate cats. Dogs scare small animals and have a strong hate/love relationship with cats.

Researchers have studied the behavior of several species of African mice. They found that while rodents stayed away when any domestic pets are present (dogs or cats), they ventured back into a home sooner if only a dog were around.

The rodents wouldn’t come back to a home if there is a cat around. Interestingly, they also found the deterring effect of dogs was more significant when cats were present.

This is likely because the instinctive dislike between dogs and cats creates a hostile environment that mice dislike.

3. Noise

Mice are afraid of noise, but usually only if it is presented in high frequency. Normal noise (what you can hear with your ears) doesn’t bother them much unless it’s from predators like dogs, cats, and owls. High-frequency sound waves, on the other hand, are irritating and uncomfortable. So much so that they may convince the critters to change location.

Unfortunately, however, mice are highly adaptable.

They will eventually grow accustomed to the noise. This makes it hard to use sound as a deterrent. Furthermore, sound may not penetrate through walls and furniture. The mice will learn this and use it to their advantage.

4. Human beings

Mice are more afraid of human beings than human beings are scared of them.

They may invade your home and steal your food, but they will scamper away at the slightest sign you’re home. Mice avoid contact with humans and always run away if it is possible.

However, if you put one into a tight spot, it may turn on you to defend itself. For this reason, you shouldn’t try to handle them.

5. Light

Although mice are not entirely nocturnal, they are more active at night than during the day. This is because they are sensitive to bright lights and have terrible eyesight.

Mice also prefer darkness because it helps them avoid large animals and predators, which are more active during the day.

Bright lights make mice feel vulnerable so that they will avoid them at all costs.

6. Vinegar


Mice will avoid the smell of vinegar, provided it is strong enough. Vinegar has a strong, irritating odor, so if used in places like pipes and u-bends where it won’t dissipate quickly, it will deter the mice.

They would find it stingy and unpleasant. White vinegar is the strongest there is, so it should be a useful mouse deterrent. There are a few ways you could use it.

(a) Put a palmful of cotton balls in white vinegar and let them soak. It would be best if you placed them in the areas you’ve seen the mice.

(b) Spray: make a 1:1 mixture of white vinegar and water. Add a teaspoon of salt and mix thoroughly. Next, apply it to the places you’ve seen the mice or evidence of their activity like chewed items, feces, or urine.

Whilst I am on the subject of natural ways to keep mice away, some folks have had success when using peppermint oil in the same way as above. Personally, I have not had much success using it to get rid of mice, so I don’t use it as a mouse repellent. When using essential oils to keep mice away, you should use them in confined spaces to keep the odor strong, including peppermint oil.

7. Bleach

Mice don’t like bleach at all. You’ve probably used bleach in some capacity, whether it’s for laundry or cleaning. If you’ve been in contact with it for even a brief amount of time, you know how terrible it is.

The odor is so strong, and the fumes hurt your eyes. As a mouse has an excellent sense of smell, it will help to deter them.

If you’re unlucky enough to touch it, it may burn your skin.

Bleach has a powerful smell. Humans can’t stand it for long, and neither can mice. They find its smell so undesirable they’ll do anything to avoid it… Bleach will repel mice!

It would be best if you mixed it with water, so your home doesn’t smell so bad, then apply it to any areas you suspect mouse activity. Leave a path the mice can use to leave your home. If you spray everything and don’t leave any clear path for the mice to escape, they’ll stay in your house longer.

Besides the fact that bleach is an effective repellent, it is also a disinfectant – it destroys harmful viruses and bacteria. Using bleach will help you eliminate any microbes present in mice’s urine, droppings, and blood.

Note: bleach can effective, but it’s deadly if used in high concentration. Bleach contains chlorine, which is very poisonous. You don’t have to drink it to be affected. Inhalation can be just as dangerous.

Bleach is also good for cleaning up when you confirm that all the mice have gone.

8. Steel wool

Are mice afraid of steel wool? Not really.

That said, steel wool will deter mice from going through cracks and crevices. Unlike wood and other materials, mice find it hard to chew through it, so it is a good deterrent.

It is most effective when used to seal small holes that mice like to crawl through.

9. Rats


Rats will kill and eat mice, so the two species aren’t friends. The practice, known as muricide, has been studied for decades.

There are lots of conflicts when the two species interact. Rats both more muscular and aggressive than mice, so they almost always emerge victoriously.

10. Squirrels

Mice fear squirrels. Although they’re primarily herbivorous, squirrel diets differ among species. They like to eat nuts, insects, fruits, mushrooms, and dried corn. However, in times of scarcity, they will eat young birds, eggs, and small mammals. Squirrels do eat meat if they need to!

Squirrels have been observed killing mice, rats, and birds.

It seems unlikely that squirrels are predators, but it is true. They tend to store food in holes or underground for the winter when food is hard to come by. Unfortunately, by early spring, those buried nuts start to sprout, so the squirrels must look for food elsewhere. They will eat anything they can find – small rodents aren’t exempted.


To give yourself the best chances of success, you will need to be persistent in applying the deterrents we’ve discussed.

It may take a while, but if you’re patient, you will get results. If you are looking to get rid of mice in your home, you should use this knowledge.

If you are worried things aren’t working out, make sure you contact a pest control professional for help.

Good luck!
