If you’re dealing with a roach problem, you may be wondering which is the best way to get rid of them – diatomaceous earth or boric acid? Both of these substances effectively get rid of roaches, but there are some critical differences between them.

In this blog post, we will compare and contrast diatomaceous earth and boric acid so that you can make an informed decision about which one is right for you.

Why Compare?

Boric acid is a slow-poisoning insecticide that kills insects by upsetting their stomach and nervous system. Diatomaceous earth is cheap, non-toxic for humans and pets, and easy to apply. Boric Acid kills more roaches than DE, but DE is better for a large area, but boric acid provides the best results in the small space.

Both roach killers must apply in a thin layer, not a thick layer, and do not forget to use them frequently if you want no disturbance of roaches. Are you concerned about cockroaches in your house and wondering how to get rid of cockroaches forever? We believe cockroach elimination is not an easy job as they have very long lives.

On top of that, they spread quickly in warm moisture places that you could ever imagine. You can see roaches everywhere at home in the bathroom, kitchen, balcony, and rooms within a week if you do not use the best roach killer for apartments.

However, do not worry! We show you the best way to kill cockroaches with boric acid and diatomaceous earth. Keep reading this post until the end and make your own decision.

Main Difference

The main difference between Diatomaceous Earth and Boric Acid is that Diatomaceous Earth kills roaches much faster than Boric Acid. DE will kill most roaches within 24 hours and all of them within a week. In contrast, Boric acid will only kill 30% of cockroaches within 24 hours, but 100% after 15 days.

Another major difference between Diatomaceous Earth and Boric Acid is the killing process. Boric acid kills cockroaches by Damaging the Stomach and Nervous System, and Diatomaceous Earth Kills cockroaches by Damaging Exoskeleton & Dehydration.

Also, you need to keep in mind that as both don’t do anything to attract cockroaches, You need to use where cockroaches are mostly seen such as near water sources, in cracks and crevices, and around food storage areas. Moreover, both of these substances work better when mixed with bait, such as sugar or honey.

Target Pest

As we have said, boric acid is an effective insecticide that can kill many types of insects, including cockroaches. This substance works by upsetting the stomach and nervous system of the insect, which leads to death. Diatomaceous earth is also effective in getting rid of cockroaches, as it works by dehydrating the insect. This causes them to die of dehydration.

Both boric acid and diatomaceous earth effectively get rid of roaches, but they have different modes of action. It is essential to know which substance is most effective against the specific type of cockroach you are trying to get rid of.

Active Ingredient

Boric acid is the active ingredient in Sodium tetraborate, a white powder derived from the element boron. This substance is a natural insecticide used for many years to kill cockroaches. Borax is mined from mineral deposits to create the material you’ll use.

Diatomaceous earth is made from the fossilized remains of diatoms, a type of algae. The active ingredient of Diatomaceous Earth is Silicon dioxide. This substance is non-toxic for humans and pets and effectively gets rid of cockroaches.

For Use In

Both can be used inside and outside the house. Boric acid is most effective when used in small, enclosed spaces, such as cabinets, drawers, and under appliances.

Diatomaceous earth can be used in a larger area, such as the attic, basement, or outside the house. See the label for the complete list of where to use and where not.

How it Works

Diatomaceous Earth and Boric Acid Roaches are two types of poisons that kill cockroaches and other insects. Both of these are highly toxic to cockroaches and other insects. The difference between them is, Boric acid is not harmful to humans and pets when used correctly, but diatomaceous earth is completely non-toxic.

The boric acid powder is sprinkled on the areas where roaches are seen. When the cockroaches crawl through the powder, it sticks to their bodies. Then when they lick themselves clean, they ingest the boric acid, which will poison them. They die shortly after that.

Since roach eats anything, they will also eat the diatomaceous earth or boric acid-related dust. It cuts their digestive system when they eat it, and they die of dehydration. You can use both of these methods to kill cockroaches.

Our Observation

In our opinion, we think that Diatomaceous Earth is a better poison than Boric Acid. The main reason is that it works faster and is also non-toxic to humans and pets. If used correctly, both of these substances can effectively get rid of cockroaches. However, we think that Diatomaceous Earth is a better choice overall.


Both are poisons Effective in killing cockroaches. The difference is how they work and how they are harmful to humans and pets. Boric acid is most effective when used in small areas, while diatomaceous earth can be used in larger areas.

Diatomaceous earth is also wholly non-toxic to humans and pets. If you are looking for an effective way to kill cockroaches, you should use one of these two poisons. I hope this article was helpful.
