Why Compare?

Borax and boric acid are both the same compound. Borax is a mineral that is taken from the ground. Boric acid is made by extracting, processing, and refining borax. Both of these products are effective at killing ants. They are so similar that many people use them interchangeably.

So, why compare them? The answer is simple: because there are some subtle differences between the two products that can make a big difference in how well they work for you. By understanding these differences, you can choose the product that is best suited for your needs.

The main difference between Boric Acid and Borax for Ants is that Boric Acid is a contact killer, while Borax is a systemic killer. What does that mean? Contact killers work immediately when they come into contact with an insect. Systemic killers, on the other hand, work slowly over time. When you use a systemic killer, the insect ingests the poison, killing them from the inside out. Most importantly, it can help you to kill the entire colony.

How Boric Acid Works

Boric acid is a contact killer, which works immediately when it comes into contact with an ant. An ant sticks to its feet and body when it walks through boric acid. The acid then dissolves the wax on the ant’s exoskeleton, which causes them to dehydrate and die.

Boric acid is most effective when it is used as a perimeter treatment. That means you would apply it outside your home, in the cracks and crevices where ants like to enter. Boric acid is a white powder that is odorless and non-staining, so it is easy to use.

One of the advantages of boric acid is that it is relatively safe to use around children and pets. However, keeping it out of reach of children and pets is essential because it can be harmful if ingested. Boric acid is available in several formulations, including powders, gels, and baits.

How Borax Works

Borax is a systemic killer who works slowly over time. When an ant ingests Borax, it disrupts its digestive system, and they eventually die. Borax is most effective when it is used as bait. That means you would put it in areas where you have seen ants, and the ants will then take it back to the colony.

It can take several days for Borax to kill all of the ants in a settlement, but it is very effective. Borax is also relatively safe to use around children and pets. It is available in a granular form, making it easy to use. One disadvantage of Borax is that it can be messy and stain surfaces.

The Borax Method

For this method, mix Borax with sugar or powdered sugar at roughly two cups per pound and sprinkle them around where ants you saw in your home. Repeat as needed to create a delicate barrier that ants won’t be able to cross.

The Toxicity Method

For this method, mix Borax and sugar or powdered sugar according to the same ratio of two cups per pound but sprinkle them around where you saw your ant problem in your home. Don’t worry about creating an actual barrier because the idea here is for those pests who come across it to have enough time before they feel any ill effects to scurry back over the border into their territory without dying on our turf.

If we repeat this procedure enough, no more ants will return because they will die from what would have turned out if we hadn’t had a huge colony.

The Coating Method

For this method, mix a half cup of Borax with an eighth teaspoon of sugar or powdered sugar, and then spread the mixture in whatever cracks you might have found ants coming out from.

This one is much easier to use because it can be done as a preventive measure before any ants even show up – they’ll go back home without ever setting foot on your property again. This will do nicely for those who only want to get rid of some pesky critters but not completely eradicate them for good!

Our Observation

We observed that the boric acid was most effective when used as a perimeter treatment. At the same time, the Borax was most effective when used as bait. However, both of these methods were effective in killing ants. The boric acid dehydrated the ant, and the Borax worked by disrupting the ant’s digestive system. Overall, we found that both of these methods were effective in killing ants.


A few different methods can get rid of ants, but the two most popular ones are boric acid and Borax. Boric acid is most effective when it is used as a perimeter treatment. At the same time, Borax is most effective when it is used as bait. I hope this has helped you understand the difference between boric acid and Borax!
