Does every bleach kill cockroaches equally? (Concentrate vs water mixture)
Using bleach to kill cockroaches is an efficient and cost-effective solution. Before we move on to how exactly you can handle cockroach infestation, let’s discuss what is bleach and why is it used to kill cockroaches.
What is bleach?
Bleach is a chemical compound that is often used to whiten or remove the color of different fibers. Bleach or in more technical terms Sodium hypochlorite is a solution made from reacting chlorine with a sodium hydroxide solution.
In daily life, bleach is used for disinfection purposes. According to Britannica, bleach works as a disinfectant because of its microbicidal properties, and “Chlorine, sodium hypochlorite, calcium hypochlorite, and hydrogen peroxide are commonly used as bleaches.”
This is why bleach is often used to get rid of cockroaches. Its chemical composition makes it a very effective repellent that can fight cockroach infestation.
How does bleach kill cockroaches?
Keep in mind, bleach does not always kill cockroaches. Roaches are resilient creatures and it takes dedication to take them down. Bleach has a strong smell that repels a variety of bugs and insects including roaches. Therefore, if your goal is deterring roaches, bleach should be your number one solution.
Bleach can kill cockroaches only if cockroaches ingest bleach or drown in it. Remember, just a strong smell does not kill the bugs. While it is a very effective repellent, it cannot kill bugs without direct contact.
Bleach cannot be used as bait because it does not attract cockroaches. Using bleach to kill roaches requires planning and a careful approach because you want them to have direct contact with bleach solutions.
Concentrate VS Water Mixture
There are different types of bleach and not all of them are successful to kill roaches. When we are talking about types of bleach, we are discussing the potency of sodium hypochlorite in it.
Household laundry bleach contains on average 5.2% sodium hypochlorite. This concentration usually is very effective against cockroaches. It will create the smell that cockroaches hate drives them away.
Mixing bleach with water can be a good decision to repel insects and keep the overall cleanliness of your house while maintaining safety.
Concentrated bleach is the one you can use to immediately attack and kill roaches. This specific bleach contains 8.25% of sodium hypochlorite therefore, it is way more potent and more capable of killing insects including roaches.
However, using concentrated bleach is not easy. It can be very harmful, so it is better to mix bleach with water.
How does chlorine bleach kill cockroaches?
Chlorine bleach is created by mixing water with the chlorine-based compound sodium hypochlorite. Chlorine is usually used as a whitening, disinfecting, or cleaning agent in household products such as detergents, whiteners, and disinfectants. While chlorine gas is very dangerous, chlorine bleach is nowhere near as poisonous.
Chlorine bleach can kill cockroaches as a result of ingestion. Chlorine can destroy the cells in organic life. This means that if chlorine bleach is ingested in bugs, they will eventually die.
How to use bleach safely to kill cockroaches?
Killing roaches using bleach is a good method. However, bleach requires careful handling because it is highly toxic. If you have decided to solve your roach problems using bleach, then you must follow safety precautions and specific steps.
- Wash your hands carefully
- Put on plastic gloves and wash hands again to ensure high-level of disinfection
- Wear a face mask
- Wear goggles, especially if you have sensitive eyes
- Dilute bleach with water and spray the mix on surfaces where cockroaches may cross
With this guide, you will efficiently drive cockroaches away. However, if you want to kill them use bleach as a guide. Since its smell is very unpleasant for cockroaches you can spray the solution in a way that directs thems to roach traps. Roaches avoid the smell so you have a high chance of directing them towards your desired destination and killing them there.
Another way of killing cockroaches with bleach is to soak bread crumbs in the solution. Although, since cockroaches can smell the mix, you may not be successful in killing them.
Additionally, CDC advises never to mix bleach with other chemical disinfectants or cleaners. So, while a lot of people might recommend you to do it. It is not worth the risk. If you cannot solve the roach problem on your own, call a licensed exterminator.
