Baking soda will kill roaches, but they must ingest it for it to work. Add sugar or peanut butter to attract them, and make sure to put it in an area where they frequent.
Baking soda traps are effective at killing cockroaches, however, it’s not enough to remove an infestation. If you have roaches, you should set up some baking soda traps but do not rely solely on this. Try some other natural pest control methods to kill some of the cockroaches around your house but you will also need help from experts to keep them gone for good.
How Fast Does Baking Soda Kill Cockroaches?
The International Journal of Advanced Research estimates that baking soda kills cockroaches within the first 12 to 24 hours. However, the timing is largely influenced by how much baking soda the cockroach ate and how hydrated it is.
Baking soda can only harm a roach when it is combined with water. As a result, if the roach is dehydrated or has not recently consumed water, there will be a delay. Even if the baking soda activates suddenly, the roach may not die immediately.
The roach may not be dead even if its exoskeleton has been fractured. It can live for several hours or days before succumbing to the poison. You may speed up the process by putting the cockroach in a sealed container filled with little water and baking soda. Because it will be unable to escape from the container, the cockroach will eventually die from dehydration or by eating more of the baking soda.
How Does Baking Soda Kill Roaches?
Baking soda will kill roaches by expanding their insides until they explode. This happens when the roach drinks water or any other liquid after eating baking soda. The baking soda reacts with the water to create an expansion of gas. This gas builds up inside the roach until it can no longer contain it and explodes. While this may not be a gory explosion, it will still crush their internal organs and crack their exoskeleton.
As mentioned, baking soda will expand when it touches water or most other liquids. This happens because sodium bicarbonate will respond to water by creating a carbonic acid reaction.
This happens in an instant and then quickly snowballs into an exothermic heat reaction. This is what gives baking soda the power to kill roaches. Ingesting just a small amount of baking soda can cause all of these reactions inside the cockroach which will eventually lead to its death.
A cockroach will likely not be able to survive more than a couple of hours. Even if it does survive, baking soda will damage the organs and nervous system. This will be enough to cause the roach to no longer be able to move, dying when it starves or when it’s eaten by a predator.
Do Cockroaches Eat Baking Soda?
No, cockroaches do not eat baking soda because they find the taste and smell unpleasant. Regardless, baking soda is toxic to cockroaches because it’s harmful to their internal organs and exoskeleton when ingested.
Also known as sodium bicarbonate, baking soda is a white powder made up of two different chemicals: sodium cation and bicarbonate anion. That’s salt, and it’s the beginning of carbonic acid. In nature, this is an important pH neutralizer because it expands whatever it’s combined with by generating gas when cooked.
Baking soda is avoided by roaches because it isn’t nutritious or edible to them. If you wish to utilize this house substance as a poison, you’ll need to combine it with other enticing foods. Roaches won’t be enticed into eating baking soda straight away.
Can You Pour Baking Soda Down The Drain To Kill Cockroaches?
Yes, you can pour baking soda down the drain to kill cockroaches. Just make sure to follow up with a vinegar solution to clean the baking soda out of your pipes. If you have a roach problem, you may also want to try using borax or diatomaceous earth. All of these substances are poisonous to cockroaches and will kill them if ingested.
That being said, pouring baking soda down the sink alone probably won’t do much to kill the cockroaches. They likely won’t be able to access the baking soda, and even if they did, they wouldn’t ingest it because they don’t find it palatable. You’re better off using one of these other methods for killing cockroaches.
How To Get Rid Of Cockroaches With Baking Soda
If you have cockroaches, you’re probably wondering how to get rid of them as fast as possible. Baking soda is a great option because it’s natural, cheap, and works quickly.
What You Need to Make a Baking Soda Roach Trap:
- A jar or container with a wide opening
- Baking soda
- Sugar, honey, or something sweet
Baking Soda & Sugar
The sugar will attract the roaches while the baking soda will kill them. Sugar is filled with starches and carbohydrates, which is everything a roach needs to survive.
Be sure to place the traps in areas where roaches are commonly seen or where they’re likely to travel. Check the traps regularly and replenish as needed until the roach problem is gone.
- Mix equal parts baking soda and sugar in a bowl.
- Place the mixture into a jar or container with a wide opening.
- Place the trap in an area where roaches are commonly seen or where they’re likely to travel.
- Check the trap regularly and replenish as needed until the roach problem is gone.
You can use any type of sugar to attract cockroaches. However, if you do not have sugar, try peanut butter, cocoa powder, honey, or syrup. If you’re in a pinch, even flour will work.
Baking Soda & Onion
Onions are a great addition to any roach trap because they’re a natural cockroach repellent. Onions contain a gas called sulfurous which is harmful to cockroaches and other insects.
- Slice or chunk an onion.
- Sprinkle dry baking soda over the pieces.
- Place them in a dish or around areas where roaches frequent.
- The onions should be replaced every 2 to 3 days.
The onion will serve as bait, with a strong and alluring aroma for cockroaches. Once they start to chew through the thick, fibrous chunks, they’ll end up consuming the baking soda that coats them.
If your onions are too wet, pat them down with a paper towel. The baking soda should not be activated until the roach has ingested it.
Does Baking Soda & Vinegar Kill Cockroaches?
Baking soda and vinegar kill cockroaches. However, it is not nearly as strong as the methods above.
Vinegar has a strong smell that deters roaches and it is not toxic to them. What makes this even worse is that vinegar causes baking soda to activate, reducing the amount of time that the concoction can work.
Baking soda will expand in the bowl if you mix the two. Even if a roach was tempted to search for the combined solution later and consume it, the expansion may not be enough to kill it.
If you have cockroaches, you’re probably wondering how to get rid of them as fast as possible. Baking soda is a great option because it’s natural, cheap, and works quickly. To make a baking soda roach trap, mix equal parts of baking soda and sugar in a bowl.
