Will Baking Soda Kill Ants? (Keeping Pests Away)

Yes, baking soda can effectively kill ants. Baking soda, also known as sodium bicarbonate, is a versatile household ingredient that can be used for various purposes, including pest control. When used correctly, baking soda can help eliminate ants and prevent their infestation in your home. In this article, we will explore how baking soda works as an ant killer and provide you with effective methods to use it.

How Does Baking Soda Kill Ants?

Baking soda works as an ant killer through a process called desiccation. Ants have a waxy outer layer on their exoskeleton that helps retain moisture and protects them from dehydration. When ants come into contact with baking soda, it absorbs the moisture from their bodies, causing them to dry out and eventually die.

Methods to Use Baking Soda for Killing Ants

Here are some effective methods to use baking soda for killing ants:

1. Baking Soda and Sugar Mixture

Ants are attracted to sweet substances, including sugar. By combining baking soda with sugar, you can create a bait that lures ants in. The sugar acts as a bait, attracting the ants, while the baking soda kills them.

To create this mixture, follow these steps:

  1. Mix equal parts of baking soda and sugar in a bowl.
  2. Sprinkle the mixture near ant trails or areas where you have seen ant activity.
  3. Ants will be attracted to the sugar and carry the mixture back to their colony.
  4. As the ants consume the mixture, the baking soda will kill them.

2. Baking Soda and Vinegar Solution

Vinegar is another household ingredient that can help repel ants. By combining vinegar with baking soda, you can create a solution that not only repels ants but also kills them.

Follow these steps to create a baking soda and vinegar solution:

  1. Mix equal parts of baking soda and vinegar in a spray bottle.
  2. Shake the bottle well to ensure the ingredients are thoroughly mixed.
  3. Spray the solution directly on ants or areas where you have seen ant activity.
  4. The mixture will kill the ants on contact.

Precautions and Tips

While baking soda can be an effective ant killer, it is important to keep the following precautions and tips in mind:

  • Avoid using baking soda in areas where children or pets may come into contact with it.
  • Always follow the instructions and recommended ratios when mixing baking soda with other ingredients.
  • Monitor the effectiveness of the baking soda treatment and reapply if necessary.
  • Consider using additional ant control methods, such as sealing entry points and keeping your home clean and free of food debris.


In conclusion, baking soda can be an effective and natural way to kill ants. By using baking soda in combination with other ingredients like sugar or vinegar, you can create baits or solutions that attract and eliminate ants. However, it is important to take precautions and use baking soda responsibly to ensure the safety of your family and pets. If you have a severe ant infestation, it may be best to consult a professional pest control service for assistance.
