Do Mothballs Repel Mice Fact or Myth

What Is A Mothball Anyway?

Mothballs are balls of pesticide and deodorant. They secrete a very strong smell due to an organic compound called 1,4-Dichlorobenzene.

1,4-Dichlorobenzene evaporates over time, turning into a gas that is very toxic to moths, and larvae. This is why they are excellent tools when storing clothing. It is a proven method of keeping moths away.


How Do You Use Mothballs?

When you purchase mothballs, they are usually stored in airtight bags to stop the evaporation process.

Once you take delivery, it is a simple case of taking the mothballs out of the wrapping and adding them to an area where you want to repel whatever it is you are trying to repel. If you would like to repel moths (which is what they are for), then you simply add the balls to your closet.

You can use mothballs to repel moths and other insects with various levels of success. Where you notice a heavy presence of insects, it is worth trying mothballs as a deterrent.


Do Mothballs Repel Mice?

The simple answer is no, mothballs do not repel mice. The gas is not toxic to mice, and nor do they seem to care about the strong smell.

I have tested using mothballs to repel mice, and each time it has failed. I have had more success by using peppermint oil to repel mice.

There are a number of reasons why mothballs do not work to repel mice, I’ll cover them here. Ultimately, the tests that I have completed have shown that mice just carry on as if the mothballs are not even there, which is frustrating!


Not Toxic To Mice

Mothballs work well for moths and other insects. This is due to the toxicity of the gas that is emitted from the mothball.

The gas is not toxic to mice.

Some insects have a natural response to stay away from mothballs due to this toxicity. As it is not toxic to mice, they will happily scamper near mothballs without a care in the world.


Smell Dissipates Quickly

Some folks have said that if you put mothballs in areas where you have noticed mouse activity, the mice do not travel through this area again. This is totally wrong!

While it is true, mothballs have a strong smell, if these are added to large areas, you will barely notice they are even there!

The bigger the area, the less effective mothballs are in general. As mice don’t seem to care about mothballs in restricted areas, they will care even less if they are added to an area where the smell just isn’t that strong!


Smell Doesn’t Bother Mice

I’ve seen mice trample over mothballs like they are bits of paper. They literally do not care about mothballs. It is like they don’t even exist!

If a mouse is happy to waltz over a mothball, it certainly will not repel it from visiting an area, right?

It was frustrating to see mice walk over the mothballs. When I started testing, I was confident that mothballs would repel mice due to the strong smell. Alas, they didn’t.


Frequently Asked Questions

frequently asked questions

What will repel mice?

One thing that will work to repel mice is to seal off their entry points. I’ve had various levels of success with natural mouse repellents such as peppermint oil. There are myths out in the wild too, so do your research well before committing to a mouse repeller. Mothballs do not work, but pepper and vinegar seem to do well.

Do mothballs repel rodents?

No, they don’t. Mice really do not care about the smell of mothballs, and the gas is not toxic to mice either. Do not waste your time trying. Instead, you should take a look to see how mice are getting into your home.

Do dryer sheets work to repel mice?

I’ve tested the theory that dryer sheets repel mice. To be honest, they do not seem to care about the scent of dryer sheets. It isn’t something that I would recommend for mouse control.


Conclusion

Do mothballs repel mice? no, they do not.

I have tested the theory that mothballs repel mice, and can say with confidence that they do not work. All you will do is waste your time and money. During which time, these mice could be expanding in numbers!

There are much better ways to control mice in your home.

One of the most successful ways to repel is is to stop them from getting into your home in the first place! This means sealing mouse entry points and removing temptation.

It is a shame, I wanted the answer to this question: do mothballs repel mice… to be yes! But it is no…

Good luck!
