Does Hairspray Kill Roaches? Best Ways Guide!

Does hairspray kill roaches? Or any other bugs, for that matter. Some people say yes, while others say no. 

In this post, I will talk about some benefits and side effects of spraying hairspray on roaches and discuss whether it actually works or not.

Does Hairspray Kill Roaches?

Hairspray is an aerosol spray that can be used to kill roaches. Hairspray contains chemicals that kill insects by suffocating or poisoning them. The spray is useful in killing hard-to-reach cockroaches. Spray light layers every day or two so that roaches won’t grow immune to the product. Moreover, it usually won’t work very well In order to kill the entire colony. 

The sticky consistency of the spray helps hold the roach in place so that it can be killed more easily, which helps prevent it from dying outside its home. 

The ingredients in hair spray are poisonous, but not deadly enough to kill a large number of roaches. You would have to use an industrial-strength pesticide.

About Hairspray

Before moving ahead, you must first know what hairspray is. Therefore, I have stated the answer to this question briefly; so that you can develop a better understanding.

Hairspray is a hair product used to keep hair in place. It is used as a styling tool, but it can also be used as a barrier between your hair and the elements.

Hairspray has been around since the 1950s when it was first introduced by Chase Products. 

The company’s founder wanted to create a product that would help people get rid of their bad hair days.

He wanted the product to be able to hold down flyaway hairs, but he also wanted it to be water-soluble so that it could be washed out easily.

Hairspray is a product that is used to keep your hair in place. It works by making the hair stick together and not fall out of place. 

This is done by coating the individual hairs with a sticky substance that prevents them from moving around too much.

Hairspray can be used for many different things:

  • As a styling tool to keep your hair looking good all day long.
  • To protect against damaging weather conditions like wind or rain.
  • Add texture and volume to thin or fine hair types.
  • It can be used as a spray to hold up curls.

What characteristics should a Hairspray Possess to Kill Roaches?

Hair sprays can kill roaches, but not all of them do. A hairspray must have a few characteristics in order to be effective against roaches. 

I have done keen research on these properties so that you can select the best hairspray for your roaches.

  • The first is that it needs to have high alcohol content. It’s best if the hairspray contains 50% or more alcohol. The higher the alcohol content, the better.
  • The best hairsprays to kill roaches need to be long-lasting, but they also need to be able to penetrate deeply into the cracks where roaches like to hide.
  • They should be able to kill roaches on contact and continue killing them for at least an hour or two after application.
  • A good hairspray will also be safe for humans and pets, as well as being non-toxic so that you don’t have to worry about accidentally inhaling it or getting it in your eyes.
  • The hairspray needs to be clear and colorless so that it doesn’t stain your furniture or clothing when you spray it on roaches.

Mechanism Through Which Hairspray Kills Roaches

A lot of people are surprised to learn that hairspray can kill roaches. But it’s true: roaches will die in a matter of minutes if you spray them with hairspray.

The mechanism through which hair spray kills roaches is actually quite simple: it dehydrates them. 

Roaches breathe through tiny holes in their bodies called spiracles, and those spiracles are located on the sides of their bodies. 

When you spray hairspray on them, it clogs up those spiracles, causing them to suffocate within minutes.

Does Pump Hairspray Kill Roaches?

There are different hair sprays available in the market, and pump hairspray is one of them, so you may have a question about the effectiveness of different types of hairsprays.

Therefore, I have done research on pump spray, so let’s have a look!

Pump hairspray is a type of aerosol that contains an insecticide. It is used for flea and tick control, as well as to kill other pests like bed bugs, mosquitoes, and roaches.

The spray is typically made of alcohol, water, and polymers. The polymers are what gives the product its unique texture and consistency.

The pump hairspray can be sprayed directly onto the roaches or sprayed into cracks and crevices where the roaches may be hiding. 

Does Aerosol Hairspray Kill Roaches?

Aerosol hairspray is a chemical that can kill roaches on contact. It will not leave a residual effect, which means that once it’s been sprayed, there’s no lasting effect on the cockroach’s body. 

However, it can cause the cockroach to die within seconds or minutes of getting sprayed.

Aerosol hairspray contains chemicals such as isopropyl alcohol, acetone, ethyl alcohol, and dimethyl ether. 

The exact ingredients in aerosol hairspray vary depending on brand name and manufacturer.

Does Non-Aerosol Hairspray Kill Roaches?

Hairsprays come in two kinds: aerosol and non-aerosol. The first type uses pressurized gas to deliver the spray, and the second uses pump action to release it. 

I have discussed the aerosol sprays above. Both types of hairspray contain chemicals that kill bugs when sprayed directly on their bodies. 

However, non-aerosol hairsprays are considered safer than aerosols because they don’t contain as many harmful ingredients, including formaldehyde bleach and ammonia.

Non-aerosol hairspray kills roaches by suffocating them.

The ingredients in non-aerosol hairspray are designed to create a coat of sticky mist that clings to the bugs and clogs their respiratory system. The bug cannot breathe, and it dies.

Some people think that hairspray is too messy for use on these pests, but it is actually one of the most effective ways to kill roaches. 

How to Use Hairspray to Kill Roaches?

The effectiveness depends on the method of application; therefore, I have listed some steps that you can follow to get the best results.

I have followed these steps to kill roaches in my house; so, you can trust their efficacy. Here’s how you can use hairspray to kill roaches:

  • Spray the hairspray around your home where you find roaches crawling on the walls or floors. 
  • It should reach every corner where they hide during the day so they will inhale its fumes for several hours after spraying it. 
  • Make sure that there is no food source around when spraying the hairspray so that they won’t go back after dying from suffocation.
  • Spray the hair spray directly onto the roach. This will kill it instantly; if you spray too far away from it, it will just run away.
  • If there are multiple roaches in your home, repeat this process until they’re all gone!
  • After spraying the hairspray all over your home, wait for about 30 minutes before doing anything else, so it has time enough to kill all those nasty pests lurking inside your house.

How Much Time is Taken by Hairspray to Work?

Hairspray is an effective way to kill roaches, but the time it takes to kill them depends on several factors.

The first factor is how much hairspray you apply. If you just spray a little bit of the stuff around the house, it might not be enough to kill all of the roaches in your home. 

You may need to spray again after a few days if there are still roaches around.

The second factor is how often you spray.

If you use hairspray once every couple of months, then there will be more time between applications—which means that it will take longer for all of the roaches to die off.

The third factor is what other pesticides or chemicals are being used in your home. 

If you have more than one type of pesticide in use at a time, then this can slow down the time it takes for roaches to die from this method as well (since they’ll have more resistance).

In most cases, it will take between 6 to 12 hours for the product to kill roaches.

If you’re using a product with multiple active ingredients, you may need to wait longer before seeing results. So, I will advise you to keep your patience.

Is Hairspray Preferred Over Pesticides?

The use of hairspray as an alternative to pesticides is a controversial topic. 

Many people believe that the use of hairspray as a pesticide replacement is an acceptable practice, while others argue that it is not safe and should be banned from use.

Chemical pesticides are used in many homes and gardens to control insects, weeds, and other pests. 

These chemicals can be poisonous to humans and animals if they come into contact with them, which is why it is important to be careful when applying them. 

Hairspray is one product that can help get rid of unwanted pests without any risk of harm to yourself or your family.

Another benefit of using hairspray instead of chemical pesticides is that it does not leave behind any residue on surfaces where you apply it. 

This means that if you spray it in your home, there will be no stains left behind on carpets or furniture. 

However, if you do use a chemical pesticide product indoors then these stains may remain until they can be removed properly by professionals who specialize in cleaning up. 

So, I have concluded that Pesticides and hairspray both have their pros and cons when it comes to killing roaches.

Pesticides are generally considered to be more effective than hairspray at killing roaches, but they also have a higher chance of causing health problems for humans if used incorrectly.

Moreover; Hairspray can also kill roaches effectively, but it does not work as well as pesticides do. 

Hairspray will only kill a small percentage of roaches that come into contact with it and will not work on all types of roaches.

Is it Cruel to Use Hairspray on Roaches?

Roaches have no pain receptors, so it is not cruel to use hairspray on roaches.

While the term “cruel” typically refers to a person’s treatment of an animal, it also refers to the way an animal is treated in terms of its environment and conditions. 

The Humane Society defines cruelty as: “The act or practice of inflicting unnecessary pain or suffering on a living creature, whether wild or under human control.”

In the case of using hairspray on roaches, it is unlikely that any unnecessary pain would be inflicted upon them. 

It is true that humans can feel pain, but insects do not. Insects have no nervous system and thus cannot feel pain; they respond only to stimuli in their environment.

Why do Roaches Act Strangely when Sprayed with Hairspray?

Have you ever noticed that on exposure to hairspray, roaches act like they get crazy? So, I have done detailed research to find out the reason behind it. So, here it is:

The nervous system of a roach is very sensitive and can be affected by many things. Hairspray contains ingredients like alcohol, which can have an effect on the nervous system of a roach. 

The substance used to make hairspray, ethyl alcohol, is poisonous to insects and can damage their internal organs. 

When sprayed on a roach, it causes them to become disoriented and slow down. This is why you often see them walking in circles or falling over when you spray them with hairspray.

Preventive Measures

There are many harmful effects of hair sprays on humans. It can cause irritation, redness, and even dizziness. 

If you are using hair spray in your home, you may want to store it safely away from children, and I advise you to follow the steps below for safe use.

  • Avoid using hairspray near food, drink, and children.
  • Do not spray directly into the air or on a person’s face.
  • Keep the can upright and away from your face when spraying.
  • Make sure the area you are spraying is well-ventilated before spraying, and do not spray indoors if there is poor ventilation in the room.
  • Make sure you’re wearing gloves and a mask when you apply the hairspray.

Can Hairspray Kill Roach Eggs?

Hairspray can be used to kill roach eggs, but it is important to use the right kind of hairspray. Some types of hairspray are not effective at killing roach eggs, but others are.

The first thing you’ll want to do is make sure you have a good quality hairspray that has insecticide in it. 

This type of hairspray is specially formulated for killing insects and will work well on roaches.

Your hair spray must contain pyrethrin as an active ingredient. 

Pyrethrin is a natural insecticide derived from chrysanthemums and can be used safely around people and pets without causing any harm or irritation.

If you find a bottle of spray with both pyrethrin and an active ingredient called permethrin, then you’ll know it’s safe for use around people and pets because permethrin doesn’t cause irritation.

Concluding Lines:

I have answered the question, “does hairspray kill roaches” just in case you were wondering. Hairspray is a better option than pesticides because it is less expensive and it’s not greener. 

But it can only kill small roaches and must be applied directly on them. 

So, if you want to get rid of roaches using hairspray, you have to spray the insecticide with great precision at short distances.


Does Hairspray Kill Insects Other than Roaches?

Yes, hairspray can kill insects such as bed bugs, silverfish, and ants. Hairspray contains alcohol, which is poisonous to a number of insects.

Is Using Hairspray to Kill Bugs Safe?

The short answer is yes. Hairspray is considered one of the safest and most effective insect-killing chemicals available on the market today.
