Are you looking for an answer to the question, does hydrogen peroxide kill cockroaches? If it is so, then your search is over, as this blog is for you.
I have mentioned the effectiveness of hydrogen peroxide against cockroaches and other bugs. You will also go through the method to use this chemical in this blog.
I have a great interest in different pest-killing chemicals and have been testing the effect of these products on cockroaches for a long time.
So, if you want to know about hydrogen peroxide along with some exciting methods to kill cockroaches, then what are you waiting for? Let’s begin!
Does Hydrogen Peroxide Kill Cockroaches?
Hydrogen peroxide is one of the most effective chemicals for killing cockroaches without wasting time. It attacks the protective outer covering of a cockroach by removing it. As soon as the outer shell of the cockroach is removed, the internal organs of the cockroach scatter around, which causes the outside flow of body fluid; this results in severe dehydration and, ultimately, death.
The amount of hydrogen peroxide plays a pivotal role in the death of a particular roach; large concentrations lead to better results, so you can increase the amount taken if required.
Moreover, preventive measures must be followed before handling hydrogen peroxide because it can damage the membranes of cells on entering the body.
What is Hydrogen Peroxide?
Before explaining the effect of hydrogen peroxide, I would like to give a brief introduction as it is essential to understand its working.
Hydrogen peroxide is a chemical compound that exists in both liquid and gaseous forms. It is transparent, having no specific color.
The primary function of hydrogen peroxide is to kill disease-causing microorganisms like bacteria and viruses, so it is used in cleaning detergents and sanitizers.
The primary purpose of cleaning is to deactivate or kill disease-causing pathogens, and hydrogen peroxide meets this requirement; therefore, it is also used for cleaning floors and kitchens.
It can also pose serious health issues if mistakenly taken by humans as it has the capability to oxidize other substances, so it reacts with compounds present in the membranes of cells.
This oxidizing ability makes it a perfect chemical to kill microorganisms and several pests, including cockroaches.
Properties of Hydrogen Peroxide
As I have stated above, hydrogen peroxide is the best cleaning agent, but it also has another beneficial use for humans; it can also be used as a medicine to heal skin cuts and lesions.
Skin cuts and lesions allow microbial growth and the building of dead skin cells, so applying hydrogen peroxide can reduce this microbial growth by killing them.
Moreover, it also contains a molecule of oxygen that reacts with other oxygen molecules, which increases its reactivity; this property helps in getting rid of damaged skin.
I have also mentioned some chemical characteristics of hydrogen peroxide in the table below, so let’s have a look.
| No | Hydrogen peroxide | Chemical properties |
| 1 | Molecular weight | 34.015 |
| 2 | Molar mass | 34.0/47g/ml |
| 3 | Density | 1.45g/cm |
| 4 | Melting point | -043 C |
These properties help the hydrogen peroxide to dissolve the structure of cockroaches’ outer shells and to kill pathogens by reacting with their cell membranes.
The unstable hydrogen peroxide is more reactive as compared to the stable one; in simple words, it can also exist in solid form, but the liquid one is more effective in killing cockroaches.
How to Use Hydrogen Peroxide to Kill Cockroaches?
The method of using hydrogen peroxide affects its working, so it is essential to understand it. I have mentioned some steps, so follow these if you want to kill cockroaches in no time.
- Hydrogen peroxide is a concentrated chemical so first of all, dilute it by making its solution with water.
- To avoid direct interaction with this chemical, wear a mask and gloves, as it also produces gas particles that can enter your body from your nostrils.
- Take 3% hydrogen peroxide in a bottle with a spraying cap.
- Add the same amount of water in it to dilute it.
- Close the cap tightly and shake it gently.
You can increase or decrease the percentage of hydrogen peroxide as its amount is directly proportional to its effectiveness.
The amount of water should be the same as the chemical. You can use this solution by spraying it on cockroaches directly or by exposing their hiding places to this chemical solution.
Things You Need to Make Hydrogen Peroxide Solution
To carry out this whole process, first, you have to ensure the presence of some required stuff. I have stated these, so let’s have a look.
- Mask: Hydrogen peroxide is also present in gaseous form, and it can react with your body once inhaled; therefore, wearing a mask is a step towards your protection.
- Lab glasses: You can mistakenly spray the solution in your eyes which can cause irritation; moving air can also alter the direction of sprayed liquid particles.
- Spray bottle: Hydrogen peroxide is a liquid, and the spraying method increases the chances of covering more surface area.
- Measuring Tube: The quantity of chemicals and water matters the most, so measuring the tube will help to avoid mistakes in selecting the amount.
- Hydrogen peroxide: It is the active chemical that is used to kill cockroaches.
- Sweeper: The dead body of a cockroach is even more threatening as compared to a living roach, so removing it is essential after completing the method.
Does Hydrogen Peroxide Attract More Cockroaches?
Cockroaches are smell sensitive, and they can easily detect any change in odor in their outside environment; they are attracted by some specific odors, which they find compelling.
Roaches can identify the food by just smelling it; therefore, insecticides having solid smells are not appreciated for killing cockroaches.
Fortunately, I didn’t find any evidence about hydrogen peroxide captivating cockroaches. Although it has a strong smell, you can use water to reduce its consistency and smell.
Similarly, cockroaches also hate some odors that are helpful in keeping them away, such as lemon and some essential oils like peppermint oil and cypress oil.
How Hydrogen Peroxide Kills Cockroaches?
As I have mentioned above, hydrogen peroxide has the ability to kill cockroaches, so now the question arises of how? So let me explain how it works.
Actually, hydrogen peroxide is a reactive chemical and is known as an excellent oxidizing agent. It is not only known to be a cleaning agent but can also cause the death of some bugs.
All insects, including cockroaches, have something to protect their bodies and critical organs; this protection is provided by their outer shell, called an exoskeleton.
The outer shell of roaches is rigid and complex, that not only keeps the organs intact but also bears some stress as it has chitin in its composition that is responsible for its hardness.
This shell also retains the body fluids inside cockroaches and prevents dehydration. Hydrogen peroxide is a chemical that readily reacts with compounds, as stated earlier.
So when you spray this chemical on a cockroach, it will react with the compounds present in the outer shell of a roach and dissolve it.
This damage to the exoskeleton results in severe dehydration that causes the cockroach to dry and, eventually, it becomes dead.
Can Hydrogen Peroxide Kill Plant-Related Pests?
Plants are also one of the victims of pests, so you are not the only one who is dealing with pests. Some bugs and insects are specific to plants.
Plants are the primary source of food for almost every living thing; cockroaches that live in the wild also feed on plant leaves to get nutrients.
These pests not only feed on plants but also cause damage to leaves and affect the growth process of these plants.
Among these plant-damaging pests, aphids, flies, termites, and worms are the most common. Fortunately, you can use hydrogen peroxide to kill these pests.
Killing these pests effectively requires a large percentage of hydrogen peroxide; generally, 5 % is recommended. Use the same steps that I have listed above to make its solution.
Moreover, also follow the precautionary measures as more concentrated hydrogen peroxide can cause irritation in your eyes and other parts of the body.
