Will Mothballs Keep Fleas Away? (Read This First!)

Mothballs are a chemical method of getting rid of insects and bugs. Mothballs were primarily invented to protect clothes from any kind of damage. But there is some confusion about the list of bugs and insects mothballs work against. 

Today, we are going to discuss and find out whether mothballs are capable of keeping fleas away or not. 

Keeping fleas away with mothballs

Mothballs are more than capable of keeping fleas away due to several reasons. Firstly, the aroma of mothballs causes problems for the fleas. The respiratory system of fleas becomes weak when the gas vapors of mothballs enter it. However, mothballs are poisonous for both animals and children.

Many people do not know about all the correct methods of keeping fleas away. There are many chemicals that are good at getting rid of insects and bugs. But not all of these chemicals can effectively terminate fleas, flea eggs and larvae. 

But the good news here is that mothballs are one of those chemicals that are able to keep fleas away. The chemical reaction caused by the toxic components of mothballs is responsible for their success as a flea repellent. 

The chemical reaction of mothballs creates respiration issues for fleas in a contained environment. Fleas will meet their fate if the gas vapor produced by mothballs manages to enter their respiratory system. 

But the chemical reaction of mothballs is not considered as being safe for children and animals. So mothballs should not be placed in open places. 

Do fleas dislike mothballs?

According to insects and bugs experts, fleas do not like mothballs at all

There are some valid reasons behind it. First of all, fleas do not enjoy the aroma emitted by mothballs. Fleas are known for having a strong sense of smell. So they will try to stay away from places that have mothballs. Because mothballs can play with the fleas’ sense of smell. 

Another alarming thing about mothballs which make it impossible for fleas to stick around them is that mothballs can effectively terminate fleas. So the fleas will not go near mothballs in their right state of mind. Insects and bugs will avoid areas that have terminating components. 

Mothballs are quite efficient at getting rid of all sorts of bugs and insects including the fleas. 

In fact, insects and bugs experts recommend using mothballs as a flea repellent due to their smell and chemical reaction. So it can be said without a doubt that fleas dislike mothballs in order to survive. 

Do mothballs terminate fleas in yard?

It is not safe to put the mothballs without an extra layer of protection. 

Then you will have to vacuum your yard with mothballs ingested vacuum cleaner to get rid of fleas. The chemical reaction caused by the mothballs inside the vacuum bag will effectively terminate the fleas in the yard.

Mothballs are known for being an effective bug and insect repellent. The repelling quality of mothballs can be used on a consistent basis to get rid of all sorts of bugs and insects. Fleas fall in the category of bugs that can be easily terminated using mothballs. 

But mothballs can get rid of flea eggs and larvae due to their chemical components. The chemical components of mothballs create a strong enough chemical reaction to get rid of larvae and flea eggs. 

If you want to decrease the reproduction procedure of fleas and stop the infestation of fleas, then getting rid of flea eggs and larvae might be the best option available. Flea eggs and larvae can not cope up with the chemical function of mothballs.

The chemical components of mothballs emit a powerful aroma that causes discomfort to the sensitive smell sense of fleas. 

Chemical reaction of mothballs:

The components of mothballs are able to create a strong enough reaction that can successfully get rid of fleas for good. Mothballs belong to the category of chemicals that can be detrimental to the survival of fleas, flea eggs and larvae. 

If the chemical reaction of mothballs takes place near a flea infestation, then it can take out the entire herd of fleas. 

Gas vapor:

The normal form of mothballs starts turning into a gas vapor form after the chemical reaction starts. The mothballs will be seen emitting gas vapor that will begin terminating the fleas upon contact. It will make it unsafe for the mothballs to stick around.
