Ants and Salt: A Powerful Pest-Control Duo

If you’ve ever dealt with a pesky ant invasion in your home, you know just how frustrating and persistent these tiny creatures can be.  

In this article, we’ll explore the fascinating relationship between ants and salt, and how you can use salt to kill ants. 

Let’s dive in and discover the scientific knowledge behind salt’s interaction with ants and its potential to help you win the battle against these persistent pests.ants salt

Does salt kill Ants? 

Yes, salt has the potential to be a potent ant killer, and it’s a remedy that has been passed down through generations.  

When ants come into direct contact with salt, it can dehydrate their bodies, leading to their demise. Salt’s ability to absorb moisture is a well-known fact, and when ants encounter salt granules, the moisture from their exoskeleton is drawn out, leaving them dried out and unable to survive.

So, if you’re wondering whether salt can be an effective ant killer, the answer is a resounding yes!

The Scientific knowledge behind salt and Ants

The science behind salt’s ant-killing ability lies in osmosis. Osmosis is the movement of water through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.  

When ants come into contact with salt, the high concentration of salt outside their bodies causes water molecules to move out of their bodies to balance the concentration.  

As a result, the ants lose vital water content, leading to dehydration and, ultimately, their demise. 

Can Salt help repel Ants?

In addition to its insecticidal properties, salt can also act as a natural deterrent to ants. While salt may not completely repel ants as some strong chemical repellents do, it can discourage them from crossing certain barriers.  

By creating a salt line or barrier in areas where ants are likely to enter, you can make it more difficult for them to infiltrate your home.  

Although they might find ways around the salt line, it could still create an extra obstacle that may deter some ants from venturing further.

How Does Salt Kill Ants? 

When using salt as an ant killer, you’ll want to target their entry points and common paths. Sprinkle a generous amount of table salt directly on the ants or along their trails.  

As ants come into contact with the salt, it will begin to absorb the moisture from their bodies, leading to dehydration and death. It’s essential to avoid disturbing the ants while they’re consuming the salt, as this could cause them to scatter and thwart your control efforts. 

Will Ants Cross a Line of Salt? 

While ants are persistent creatures, they can be cautious when encountering new and unfamiliar substances.  

Creating a line of salt along entryways and areas where ants frequent might deter some ants from crossing it. The abrasive texture of salt can be uncomfortable for ants to traverse, and the risk of dehydration may cause them to seek alternative routes.  

However, it’s essential to remember that not all ant species will be equally affected by the salt barrier, so it may not be a foolproof solution. 

How to Use Salt to Get Rid of Ants? 

To use salt effectively for ant control, follow these steps: 

  • Identify Entry Points: Observe the ants’ movement and identify their entry points into your home. 
  • Clean the Area: Before applying salt, ensure the area is clean and free of food particles that might attract ants. 
  • Sprinkle Salt Directly on Ants: If you spot a trail of ants, sprinkle table salt directly on them. The salt will absorb moisture and lead to their demise. 
  • Create a Salt Barrier: For areas where ants commonly enter, create a line of salt to act as a barrier. This may deter some ants from crossing it. 
  • Repeat as Needed: Depending on the severity of the infestation, you may need to reapply salt regularly.

Other Natural Methods of Ant Control 

While salt can be an effective natural remedy for dealing with ants, there are other methods you can consider to tackle ant infestations without resorting to harsh chemicals. Let’s explore some additional natural approaches to ant control that you can use in conjunction with or as alternatives to salt.

  • Vinegar Solution: A mixture of equal parts vinegar and water can be sprayed on ant trails, entry points, and surfaces to deter ants. The strong smell of vinegar disrupts their scent trails, making it harder for them to navigate. 
  • Citrus Peels: Ants dislike the smell of citrus, so placing citrus peels or using citrus essential oils near ant-prone areas can help repel them. 
  • Cinnamon: Sprinkling ground cinnamon along ant paths or near entry points can be a natural deterrent. The strong scent of cinnamon disrupts their communication and foraging patterns. 
  • Peppermint Oil: Ants also dislike the scent of peppermint. Mixing a few drops of peppermint essential oil with water and spraying it in affected areas can be effective in keeping ants at bay.

Considerations When Using Salt to Repel Ants 

While using salt as a natural ant deterrent can be helpful, there are some important considerations to keep in mind: 

  • Pet and Child Safety: If you have pets or small children in your home, be cautious when using salt or any other natural repellents. While salt is generally safe for pets and kids, it’s best to keep them away from direct contact with the salted areas. 
  • Effectiveness on Different Ant Species: The success of using salt as an ant repellent may vary depending on the ant species and the severity of the infestation. Some ant species may be more resilient and less deterred by the salt barrier. 
  • Cleaning and Reapplication: Rain or cleaning activities can wash away the salt barrier, reducing its effectiveness. Regularly check and reapply the salt as needed to maintain the deterrent effect. 


Does Epsom Salt Kill Ants? 

Epsom salt, chemically known as magnesium sulfate, shares some similarities with regular table salt but isn’t as effective in killing ants. While it may have a slight dehydrating effect, it’s not as potent as table salt for pest control purposes. Stick to regular table salt for ant-killing purposes. 

Does Salt Directly Kill Ants? 

Yes, when ants come into direct contact with salt, it can lead to their demise. The dehydrating properties of salt cause water to be drawn out of their bodies, leaving them dried out and unable to survive. 

Will Salt Kill Fire Ants? 

Fire ants are notoriously resilient, and while salt can have an impact on them, it might not be as effective as it is on other ant species. Dealing with fire ant infestations often requires more extensive measures, and it’s best to seek professional help in such cases. 

Can Boric Acid Replace Salt in Killing Ants? 

Boric acid is another natural remedy for controlling ants, and it works differently from salt. When ants consume boric acid, it interferes with their digestive system and leads to their demise. While both salt and boric acid can be effective in ant control, it’s essential to use them carefully and keep them away from pets and children.
