Baking Soda and Ants | Information

There are more than 12000 known species of ants that can attack your house or garden. Most of them are harmless and do not cause any structural damage. However, well-developed colonies of ants can cause serious problems. To address the problem, you can use baking soda as a natural ant repellent as well as an insecticide to get rid of ants. It is also referred to as sodium bicarbonate.

The acidic mineral is usually available in powdered form. It is odorless, with white color and salty taste. This is a natural and safe way to eradicate ants, but you will need to mix it with food supplements to lure ants into consuming it. Baking soda can also be used to keep the ants away from your house. This chemical does not harm your pets until it is consumed in a large quantity.

How Does Baking Soda Kill Ants?

Baking soda can be used to prepare natural insecticide sprays as well as baits. When the powder is directly sprinkled over the ants, it absorbs water from their exoskeleton and drys them out. Similarly, when baking soda and vinegar solution is sprayed over ants, it causes a violent reaction and kills the ant instantly after the treatment.

The baking soda works more effectively when we use it as bait with some ant attractants. The ants take the bait to their nests and feed the entire colony. After ingestion, the chemical reacts with the digestive system of ants and releases carbon dioxide, which eventually causes them to die.

How Long Does Baking Soda Take to Kill Ants?

Baking soda can kill the ants in a few hours. However, the exact time period to eliminate an entire ant colony depends upon various other factors such as the level of infestation, type of ant, etc.

Homemade baking soda sprays may take longer to kill ants than the commercial ant baits. The smaller infestation of ants can be dealt with within 2 to 4 days whereas the larger infestation may require more than a week. Baking soda spray kills the ants immediately after application.

The scent of sugar attracts the ants and, the similar texture of sugar and baking soda confuses the ants.

As a result, the worker ants take the baking soda along with sugar to their nests and consume the bait. When the bait works, baking soda causes a reaction inside the digestive systems of ants. All of this results in their death.

Does Baking Soda Work on Fire Ants and Carpenter Ants?

Baking soda-based ant killers are effective for almost all the type of ant species. Carpenter ants and fire ants are commonly recognized as both indoor and outdoor pests.

Observe the food preference of invader ant species and prepare a mix according to its behavior. Carpenter ants are fond of sugar-based food whereas fire ants like both protein and sugar. You can prepare a perfect baking soda bait according to the ant type.

The mixture of baking soda and powdered sugar acts as a natural bait for carpenter ants. Baking soda and vinegar mixture works best in case of fire ants. You can also add other ingredients to prepare different types of baking soda ant killers such as vitamin C powder, jams, honey, etc.

Our step by step guide will help to control ants with baking soda. It is an effective pest control strategy to exterminate ants from your house or garden which includes, inspection, treatment and prevention.

Step 1: Inspection of Infested Areas

To get rid of the ant infestation you first need to do a careful inspection and investigations of your house both indoor and outdoor. Monitor the ant trails, their access points, and ant mounds. It will help you to decide the required quantity of the baking soda mix. 

Observe the eating pattern and behavior of ants before the application of ant killer. Some ant species prefer sugar-based food whereas others like to eat greasy food. Identification of ant species and careful inspection of the infested sites will help you to get the best outcomes.

No products found.

You can also test a sample bait to check the eating behavior of a specific ant species. We suggest putting multiple types of baits (liquid or solid) at the same time to target every type of ant in the nest (worker, larvae, and queen).

Put the baking soda ant baits or traps at multiple locations near the ant trails and closer to ant mound to attract the ants out of their shelters. The ants will take the bait back to their nests and will feed the entire colony including the queen. The baking soda will cause suffocation and lead to their death.

Smaller ant infestations can be eliminated in a few days whereas larger infestation can take a few weeks depending upon their level of infestation. This method is slow acting but produces the best outcomes.

It is perfect for the sites where you cannot manually approach ant mounds. Monitor the site regularly and apply or replace baits if needed. Further, we have given some additional baking soda baits recipes to control ant infestation.

Baking Soda and Sugar for Ants

To prepare baking soda and sugar bait, combine 1 tablespoon of powdered sugar (icing or confectioners sugar) with 1 tablespoon of baking soda (1:1). You can increase the quantity of sugar and baking soda if required. Try not to use regular sugar to prepare the mix because ants will try to separate sugar from baking soda.

You can replace sugar with honey, jam, or other sugary food items. The sugary food items will help to attract the ants. Put the mixture near mounds, ant trails, and alongside hole or cracks to eradicate ant infestation. If you have prepared a sticky bait then try using disposable containers or tape. Replace the baits often.

Peanut Butter and Baking Soda to Kill Ants

To prepare peanut butter and baking bait, mix 2 tablespoons of baking soda in 1 tablespoon of peanut butter. The bait is best for ants that are fond of greasy or protein-based food such as thief ants. Put the mixture on a disposable container and place it near the entry points, closer to ant trails and mounds to lure ants.

Vitamin C and Baking Soda to Kill Ants

To create a baking soda and vitamin C bait, mix baking soda, vitamin C tablet, and icing sugar in equal quantity. Mix them together and apply the mixture at the infested sites or near the ant trails. You can also add water in the mixture to prepare liquid bait.

Baking Soda and Diatomaceous Earth to Kill Ants

Diatomaceous earth is an organic and non-toxic compound, made from the shells of diatoms. It can be used to get rid of a number of pests. You can prepare baking soda and diatomaceous earth mixture very simply by mixing them together.

Baking Soda and Borax to Kill Ants

Like diatomaceous earth, borax powder and baking soda mixture can also kill ant colonies. You can sprinkle the insecticide powder directly on the ants and ant mounds to eliminate their entire colonies. Borax powder is toxic and can cause eye problems and skin rashes.

This is why you need to use personal protective equipment (gloves, mask, and eyewear) to avoid any mishap. You can purchase diatomaceous earth, borax powder, and baking soda commercially to prepare DIY natural ants killers.

How to Kill Ants With Baking Soda and Vinegar?

To get rid of ants using baking soda and vinegar, apply baking soda over the ant mounds and then pour vinegar over it. Baking soda is acidic in nature, and when another acid is added into the mix, it causes a violent reaction.

You can also make baking soda and vinegar control solution by adding baking soda in vinegar and water solution (1:1). Pour the mixture into a bottle to use it as a spray or directly drench the sufficient quantity of the mixture over the mounds to get rid of ants.

Baking Soda and Cooking Oil Spray

To make baking soda and cooking oil spray, mix 1 teaspoon of baking soda in 1 teaspoon of cooking oil. Before the application of insecticide spray, add the mixture in 1 cup of warm and pour this solution into a spray bottle.
