If you have ever dealt with an ant infestation in your home, you know how frustrating it can be. Sugar ants, in particular, are a common nuisance in many households. One solution that often comes up in discussions about ant control is boric acid. But does it really work? In this article, we’ll explore the effectiveness of boric acid in killing sugar ants.

What is Boric Acid?

Boric acid is a white, crystalline powder that is often used as an insecticide. It is made from boron, a naturally occurring element. Boric acid works by disrupting the insect’s digestive system and causing dehydration. It is considered a low-toxicity insecticide, which makes it a popular choice for controlling pests in and around the home.

How Does Boric Acid Kill Sugar Ants?

Boric acid works by interfering with the ant’s digestive system. When ants come into contact with boric acid, they will ingest it as they groom themselves. The boric acid will then begin to disrupt the ant’s digestive system, causing it to dehydrate and eventually die. Boric acid is also effective in killing ant colonies, as it can be transferred from one ant to another through grooming and feeding.

How to Use Boric Acid to Kill Sugar Ants

To use boric acid to kill sugar ants, you will need to make a bait using sugar and boric acid. Mix equal parts of sugar and boric acid in a bowl and add enough water to create a paste. Place small amounts of the paste in areas where you have seen ant activity, such as along baseboards or near food sources. The ants will be attracted to the sugar and will ingest the boric acid as they eat the bait.

Precautions When Using Boric Acid

While boric acid is considered a low-toxicity insecticide, it is still important to take precautions when using it in your home. When making the bait, be sure to wear gloves and avoid inhaling the powder. Keep the bait out of reach of children and pets, and do not place it near food or food prep areas. If you have a severe ant infestation, it may be best to consult a professional pest control service.


In conclusion, boric acid can be an effective solution for controlling sugar ants in your home. By disrupting the ant’s digestive system, boric acid can kill individual ants and entire colonies. However, it is important to use caution when handling boric acid and to follow proper safety precautions. With the right approach, boric acid can be a safe and effective tool in your battle against sugar ants.
