Does Borax Kill Roaches?

You never want to find out that you have a roach infestation in your home, but once you do, it’s important to take action immediately. There are many different products on the market that claim to eliminate roaches, and some of them do work to an extent, but borax powder remains one of the most effective tools in your arsenal. In this post, we’ll talk about does borax kills roaches? and some uses of borax roach killer.

This handy substance combines several different pesticides into one all-natural product, which means you can rid your home of roaches quickly and easily.

The active ingredient in borax is sodium tetraborate, which is a natural mineral salt. This compound disrupts the roach’s digestive system and causes it to die of dehydration within a few days. This method of roach control is especially effective because it can kill the entire roach colony as well as any eggs, which is something that many insecticides don’t do.

In order to truly get rid of the roach problem, you have to know where roaches are come from. Most of the time, the only way you discover that you have a roach problem is when you see a roach scurry across the floor or into another room. This means that there is probably a crack or other opening in your foundation, leading the roaches to come inside.

How Does Borax Kill Roaches?

Borax is natural and effective. This makes it the perfect choice for most people who are working to get rid of roaches. It’s safe enough that you can use it in your kitchen but strong enough that it will kill all of the roaches that try to cross its path.


Borax gives roaches a fatal case of stomach ache. Roaches eat borax and it interferes with their digestive system. It is also poisonous to the baby roaches still in the egg stage.

Roaches aren’t just gross, they can spread diseases too. If you have a roach problem in your home, it’s best to take care of it immediately by using borax.

Borax Recipes to Kill Roaches

Borax is highly effective when used alone, but it also has several recipes that can take care of your roach problem even faster. The best part about these recipes is that they are all natural and completely safe for you and your family to use around the home. You won’t be dealing with harsh chemicals or fumes like you might with other commercial products.

Borax and Sugar

This mixture is perfect for those little roaches that like to come into your kitchen at night. All you have to do is mix borax and white sugar together in equal parts, and sprinkle it directly onto the roaches or into any cracks that you’ve seen them coming in and out of. They will eat the dust, get sick, and then die.

Additional tip: To make it even more effective, pour some water into the mixture to create a paste that will stick to surfaces and be harder for the roaches to scrape off.

Borax and Baking Soda

This recipe is a bit more complex than the previous one, but only slightly. Mix together one tablespoon of borax, one tablespoon of baking soda, and three tablespoons of white flour to create a paste that you can spread around your home. Just like the sugar mixture, spread this paste in cracks and other areas where you’ve seen roaches hanging out.

Additional tip: If you want to make it easier for yourself, put the paste into a container with a lid and use the end of a paintbrush to spread it around.

Borax and Peanut Butter

This combination is best for roaches that like to hide in dark places and don’t seem to want to venture out into the open. It’s also an excellent way to take care of roaches that like to burrow into the walls and other areas that you can’t always see.

Combine borax and peanut butter in a one-to-one ratio, and mix to create a thick paste. Then, spread the paste anywhere you’ve seen roaches and where you think they might be hiding.

Additional tip: If your roach problem is very bad, you might want to use stronger measures.

Borax Balls for Roaches

This mixture might seem a bit strange, but it’s actually quite effective at killing roaches. You’ll need to create a borax ball that will kill the roach by ingestion.

Combine borax and sugar or flour, mixed with cornstarch and onion powder. Add water to make a thick paste. Roll it up in a piece of tin foil, and let it dry for about a day before using.

Next, you want to put the ball in places where roaches are likely to come across it. These include areas like under your stove or refrigerator. They will eat the borax ball and die soon after.

Additional tip: Don’t make your balls too big; otherwise, they won’t be able to reach them.

Are Borax and Boric Acid the Same Thing?

They are both made up of boron, but otherwise have no other similarities. Boric acid is much more poisonous than borax. If you’re not careful when using it, boric acid can become poisonous for anyone that comes into contact with it.

Borax is much less poisonous and can even be used around food. However, you should still keep it away from your children and pets, as they might mistake it for a sugary treat.

Moreover, borax can be used to kill roaches, ants, bed bugs, rodents, and other insects without being poisonous to people.

If you want to take things a step further, it’s recommended that you get some roach tablets. These are specially made to kill roaches and other insects with chemicals that are just as strong as commercial pesticides, but completely safe to use around your kids and pets.

They’re also much easier to spread around your home. You can easily place them in cracks where roaches are likely to travel. Also easily available in online stores and local stores.
