Does Baking Soda Kill Ants? Natural Ant Control Solutions Unveiled

does baking soda kills ants?

Whether you’re dealing with tiny sugar ants in your kitchen or encountering an invasion of carpenter ants, an ant infestation can be a nuisance and disruption in any home. You may have heard about the use of baking soda, also known as sodium bicarbonate, as a natural remedy against these tiny creatures. But does baking soda kill ants? Let’s investigate the truth behind the myth.

Key Takeaways

  • While baking soda can kill individual ants, it’s questionable whether it’s truly effective in eradicating an entire ant colony, particularly for larger infestations. It’s crucial to use a combination of methods and sometimes seek professional help for stubborn infestations.

Understanding Ant Behavior

Crucial to any battle is understanding your opponent, and the same applies when dealing with an ant infestation. Ants, as tiny as they might be, are complex creatures with a diverse range of behaviors and roles within their colonies. Unraveling these behaviors can provide pivotal insight into effectively managing an ant invasion.

In an ant colony, roles are distributed based on a well-organized social structure. Specific attributes and responsibilities are assigned to different types of ants within the colony, namely the queen, males, soldiers, and worker ants. The queen’s primary function is reproduction, while the males’ sole purpose is to mate with the queen. Soldiers protect the colony, and the worker ants, as the name suggests, do most of the foraging and feeding.

Worker ants are the common invaders you’ll likely see parading around your home. These diligent creatures are on a never-ending mission, seeking food to sustain their entire colony.

They follow scent trails laid out by scout ants, who are the ‘ground-breakers,’ exploring new territories and locating food sources.

Once a scout ant finds a food source, it trails back to the colony, leaving a pheromone path for worker ants to follow. This behavior is seen consistently across various species, whether they’re typical house ants, fire ants, or the more destructive carpenter ants.

Understanding Ant Trails

Understanding these ant trails is key to managing an ant problem effectively. If you notice a line of ants in your home, it’s likely that they’re following this scent trail. Disrupting these trails can disorient the worker ants, making it difficult for them to find their way back to the food source.


Dealing with a more dangerous species such as carpenter ants, which can cause substantial property damage, requires a different approach. Their nesting habits involve burrowing into damp or damaged wood, creating extensive galleries. Managing these ants not only involves eliminating the workers and the food source, but also addressing the structural water issues leading to damp wood that they find attractive.

Ultimately, it’s not enough to kill the ants you see to handle an ant infestation effectively. It’s essential to understand their behavior, disrupt their trails, address their food source, and sometimes, even their nesting habitat in the case of carpenter ants. These in-depth insights into ant behavior form the backbone of a comprehensive and holistic ant management strategy.

Using Baking Soda for Ant Control

Looking towards our kitchen cupboards for a solution to an ant infestation is not uncommon. Among household items, baking soda is often highlighted as an inexpensive, non-toxic alternative to commercial insecticides.

The concept behind using baking soda is that it purportedly interferes with the ants’ natural physiology. When ingested, the sodium bicarbonate in the baking soda is said to react with an ant’s naturally occurring stomach acids, leading to the production of carbon dioxide gas, which the ants cannot survive. Essentially, the theory is that baking soda causes ants to ‘explode’ from the inside out.

This method is applied in two primary ways:

1. Baking Soda and Powdered Sugar Bait

One of the most popular methods involves creating an ant bait using a mixture of equal parts baking soda and powdered sugar. This combination exploits ants’ affinity for sweetness.

Here’s the step-by-step of how this method is carried out:

In a shallow container easily accessible to ants, mix equal parts baking soda and powdered sugar. The exact volume may vary depending on how significant the ant problem is, but a cup of each is generally a sufficient starting point.
The powdered sugar acts as bait, drawing the ants in, while the baking soda serves as the poison. Ants, typically unable to differentiate between the sugar and baking soda granules, carry back both to their colony.
Back in the colony, the ants share their bounty, including the sugar-laced baking soda, with other ants in the colony, including the larvae and the queen, broadening the impact of the toxin.
Once ingested, the baking soda should theoretically cause a fatal reaction in the ants, effectively working as a means of exterminating the colony from within.

2. Baking Soda and Water Solution Spray

A second method uses a baking soda solution for spraying directly at ants and their paths.

  • To create this solution, you’ll need to mix about one teaspoon of baking soda with a cup of warm water in a spray bottle.
  • Once your solution is ready, spray it directly onto visible ants, entry points, and other places where you’ve noticed ant activity.
  • This method targets individual ants and can disrupt ant trails by erasing their scent marks. It proves to be a quick fix for visible ants but may not be as effective in targeting an entire colony.

In theory, using baking soda seems to be an easy, affordable, and non-toxic method for ant pest control. It is an excellent example of leveraging basic understanding of ant behavior for pest control.

While this method may be effective for small-scale infestations, more severe or larger ones may require a more robust and comprehensive approach.

Other Natural Ant Killer Solutions

Baking soda isn’t the only natural substance you can use to deal with an ant infestation. Alternatives such as diatomaceous earth and boric acid have shown significant results in eradicating ants. Lemon juice, vinegar, peppermint oil, and even common household items like dish soap can be used as effective, non-toxic solutions in a spray bottle.
