Does Baking Soda Kill Ants? (4 Proven Ways)

Gardeners, vegetable growers, apartment dwellers, and private homeowners all face ant control as a constant issue. Ants are everywhere. 

These pests wreak havoc on vegetables and fruit trees, and when they make their way into people’s homes, they cause trouble. 

Ants can be eliminated from the garden and vegetable garden as well as the home by using baking soda. This method has the advantages of being environmentally safe, readily available, and highly efficient.

How Does Baking Soda Work On Ants

Sodium hydrogen carbonate contributes to the formation of an alkaline environment. This property is frequently used to treat a variety of diseases and to clean soiled surfaces. 

Few people know that when it enters an ant’s body, it causes a chemical reaction with acid, which is abundant in their bodies. As a result, the pest’s outer shell is destroyed, and it dies. 

Because soda does not appeal to ants as a food source, it can be combined with a wide range of other ingredients that these insects will never reject.

Solution Recipes

Many baking soda-based recipes exist, allowing you to successfully combat ants without polluting the environment. It is especially important if the insects are scattered throughout your garden plot or houseplants. 

Using chemicals, on the other hand, results in contaminated soil, fruits, and vegetables, all of which can harm humans.

Poisonous substances used in apartments or private homes can poison the people and pets who live there. 

Sugar and vinegar are the most common products that are combined with baking soda. You can also use it without water. To get rid of anthills, you can use either baking soda or soda ash.

The latter has more alkalizing properties than the former. As a result, it will have a more aggressive effect on ants and produce better results.

Dry Powder NaHCO3

The most straightforward method is to sprinkle dry sodium carbonate powder on the anthills. After a few days, there will be far fewer insects, and they should eventually vanish.

You can treat several beds in the vegetable garden at once if pests have infested a large area of the garden. NaHCO3 can alkalize soils with low acidity, so some gardeners advise caution when using this method on such soils.

However, several buckets of powder are required to significantly alter the soil’s composition, while only a few handfuls are required to control ants. 

Such a small amount has no effect on the chemical composition of the soil. The dry form of sodium bicarbonate makes it easy to use in insect-infested plants. 

You can do this by sprinkling the powder on the areas where they live, and then cleaning the house or apartment with water a few days after that.

Given that ants are voracious consumers of sweets, sugar may be an effective ant control tool. Sugar and alkali baits can be made in one of two ways that both work well.

In order to make the sugar bait, follow these steps:

  • 0.5 cup of NaHCO3
  • 1 cup powdered sugar
  • 2 tablespoons of water

Everything is thoroughly mixed, and then it’s spread out near the anthills so the ants can find it easily. 

As soon as the sweets attract insects, they will congregate around the bait and eat it, which will result in their demise.

Water Solution

You can also use other methods to keep ants at bay. For instance, a baking soda solution in hot water. 

To prepare, combine two tablespoons of dry powder with 1.5 liters of boiling water and stir until completely dissolved. 

Pour the solution into a plastic bottle after it has had a chance to cool slightly. 

Mix thoroughly and start treating the garden or vegetable garden. 1.5 to 3 liters of baking soda solution are required for one small anthill. 

Limit access to oxygen by covering anthills in dirt or sand. This method will eliminate a significant portion of the insects, and the remainder will flee the settled territory.

Fight Ants With Vinegar

When it comes to ants, vinegar is a potent ally. For this, use a thin rod to bore holes in the anthill that are deep enough. 

Fill the holes with baking soda, then cover with vinegar. When this happens, there will be a chemical reaction, and the ants will be forced to flee quickly. 

For best results, use sand or soil to fill in the holes that have been treated with the vinegar solution. 

Because one application of sodium bicarbonate will not be enough to eradicate the entire ant colony, you must use multiple applications of the methods described above.

In most cases, ants will no longer return to inhospitable hosts after a series of such treatments.

With Tar Soap

Ants are frequently to blame for an increase in aphid populations on plant stems and leaves. You can use the following method to get rid of all pests at once:

  • Use a grater to finely grind tar soap.
  • To the ground up soap, add 1 liter of water and 1-2 spoonfuls of NaHCO3.

Stir the mixture thoroughly until the soap and soda are completely dissolved. Strain the soapy liquid through gauze and pour it into a sprayer-compatible container. 

Use the soap liquid to treat aphid-infested plants. This method works best when combined with anthill treatment with dry powder, water, or vinegar solution.

The Effect of Baking Soda Application

The ants die within a few minutes of being exposed to the alkali, and the remaining insects rush to drag their eggs away from the affected area. 

To keep them from settling within a few meters of the treated area, water the solution or sprinkle the dry powder on the entire area at once. 

However, if this isn’t an option due to crops in the vegetable garden, you can apply the lye in small sections. 

In some cases, even such a measure can keep pests at bay for an extended period of time. 

You should use dry powder or sweet bait with its addition if the ants have settled in your house or apartment.

Personal Experience with Baking Soda and Ants

I spent a long time trying various chemicals to get rid of ants. I noticed that the ants were not decreasing over time, so I decided to stop poisoning the soil and plants. 

I was recently advised by a rural neighbor to combine baking soda and vinegar. The ants vanished after two treatments. 

My vegetable garden is infested with so many ants that it is simply impossible to plant and care for plants safely. 

I’ve tried a variety of methods to get rid of the pests, including baking soda. 

However, so far, none of the methods have been effective in ridding the plot of pesky insects. 

For the sake of curiosity, I tried treating the anthill with regular baking soda. 

The garden was abundantly filled with insects, and after two weeks, there was not a single ant left in the treated area.

According to the feedback, the lye application has different effects on different people. 

For example, some gardeners completely eradicate large pest colonies, while others see only temporary results: fewer insects for a while, but the number returns to normal after 2-3 weeks. 

If you’re fighting an infestation indoors, you’ll find that getting enough pesticides into the small crevices under the flooring, where pests can hide, can be a challenge. 

In spite of this, baking soda outperforms synthetic alternatives in a wide range of situations and applications. 

For starters, it is gentle on plants and soil. As a second benefit, its price is significantly lower compared to those of specialty chemical stores.

Final Words

If you’ve decided to get rid of all the ants in your garden, consider how much of a threat they are to your health and well-being.

Baking soda may be the most effective way to get rid of ants in your house while also being environmentally friendly and simple to use.
