How to Use Salt to Kill Ants

If you’re looking for a natural ant repellent, using salt to kill ants is a great DIY solution. The best part? Chances are, you already have salt in your kitchen!

Here’s how to use salt to get rid of ants:

  1. Clean the area where you’ve spotted ants, as sugar, crumbs, and other food debris can attract them.
  2. Locate the ants’ entry point, and create a barrier of salt around it. This will keep the ants from entering your space.
  3. You can also create a salt solution by mixing salt and boiling water. Pour the solution into a spray bottle and apply it to areas where you’ve seen ants.
  4. Another option is to mix salt and sugar in equal parts and leave it in a shallow dish near the ants’ nest. The ants will be attracted to the sugar, and when they consume the salt, it will dehydrate and ultimately kill them.
  5. Repeat these steps as necessary until the ant infestation is gone.

Keep in mind that using too much salt can damage your lawn or garden, so it’s a good idea to use it sparingly and only in areas where you’ve spotted ants.

TIP: If you’re dealing with a particularly stubborn ant infestation, try combining salt with other natural ant repellents like vinegar or essential oils. This can increase the effectiveness of your homemade ant killer.

By following these simple steps, you can use salt to effectively get rid of ants without the need for harmful chemicals or expensive pest control services.

The Science Behind Salt’s Ant-Killing Properties

Now that we know salt is a natural ant repellent, let’s explore exactly how it works. When ants come into contact with salt, it absorbs the moisture from their bodies, causing them to become dehydrated and die.

This is because ants rely on a delicate balance of water and electrolytes in their bodies to survive. Salt disrupts this balance and causes them to lose too much moisture.

In addition, the sharp edges of salt crystals can also cause physical damage to ants’ exoskeletons, making them more vulnerable to dehydration and death.

While salt can be an effective natural ant repellent, it’s important to use it in moderation. Too much salt can create an environment that is too salty for plants and other wildlife to thrive in.

Additionally, salt may not work as well on certain species of ants or in certain situations, such as in wet or humid environments where ants may have easier access to water.

Overall, salt can be a powerful tool in your ant control arsenal when used correctly and with caution.

Benefits of Using Salt as an Ant Killer

If you’re looking for a natural and effective way to control ants, salt is a great option. Not only is it readily available in most homes, but it’s also an environmentally friendly alternative to commercial ant killers.

One of the biggest advantages of using salt as an ant killer is that it’s a natural ant repellent. Unlike chemical pesticides, salt won’t harm the environment or pose a risk to humans or pets. It’s also affordable and easy to use, making it a great DIY ant treatment option.

Another benefit of using salt is that it can be used both indoors and outdoors. Whether you’re dealing with an ant infestation in your kitchen or your garden, salt can be an effective way to control ants and prevent them from returning.

Using salt to kill ants is also a great homemade ant killer solution. By using common household ingredients like salt, vinegar, and baking soda, you can create a natural ant repellent that’s both effective and safe to use around your home.

Overall, if you’re looking for a natural and affordable way to control ants, salt is definitely worth considering.

If you’re looking for a more targeted approach, there are other natural ant repellents to consider, such as vinegar or essential oils.

Finally, when using salt to kill ants, it’s important to follow proper safety procedures. Wear gloves and protective clothing, and avoid getting the salt mixture on your skin or in your eyes.

By keeping these precautions and considerations in mind, you can safely and effectively use salt as an ant killer to rid your home of unwanted pests.

DIY Ant Treatment with Salt: A Step-by-Step Guide

If you’re looking for a natural way to get rid of ants, using salt as an ant killer is a great option. Here’s a step-by-step guide on how to create a homemade ant killer using salt and other household ingredients.

Materials: Instructions:
Table salt 1. Sprinkle salt directly on ant trails, nests, and entry points.
Boiling water 2. Mix 1/4 cup of salt with 4 cups of boiling water. Stir until the salt dissolves.
Borax 3. Add 1 tablespoon of borax and stir until it dissolves.
Granulated sugar 4. Add 1/4 cup of granulated sugar and stir until it dissolves.
Container with lid 5. Pour the mixture into a container with a lid (a plastic container or mason jar work well).
Cotton balls 6. Place cotton balls in the container, making sure they are fully saturated with the solution.
7. Place the container near ant trails and entry points, or place the soaked cotton balls directly on these areas.

This homemade ant killer is an effective method for killing ants in and around your home. The salt dehydrates the ants, while the borax and sugar act as baits, attracting them to the cotton balls. Once ingested, the borax damages the ants’ digestive systems, ultimately killing them.

Remember to keep this mixture out of reach of children and pets, as borax can be toxic if ingested.

If you prefer not to use borax, you can create a simple salt and water solution and spray it on ant-infested areas instead. This mixture won’t be as effective as the borax solution, but it still works as a natural ant repellent.

Other Natural Ant Repellents to Consider

While salt is a great option for naturally repelling ants, there are several other homemade ant killer solutions that you can consider. These methods are also eco-friendly and can save you money on commercial ant control products.

Citrus Peels

Ants hate the smell of citrus, so you can use citrus peels to keep them away. Simply place orange or lemon peels near areas where ants are entering your home or property.


Cinnamon can also be effective in repelling ants. Sprinkle ground cinnamon around entry points or create a cinnamon oil spray by mixing ground cinnamon and water in a spray bottle.


Vinegar is another common household item that can be used to repel ants. Mix equal parts of vinegar and water in a spray bottle, then spray the solution in areas where ants are present.

Baking Soda and Powdered Sugar

A combination of baking soda and powdered sugar can be used to eliminate ants. Mix equal parts of both ingredients and place the mixture in areas where ants are present. The sugar will attract the ants, while the baking soda will kill them.

Diatomaceous Earth

Diatomaceous earth is a natural powder made from the fossilized remains of tiny organisms. It is safe for humans and pets but deadly for insects, including ants. Sprinkle diatomaceous earth around entry points or directly on ants to kill them.

How to Prevent Ants from Returning

By taking these measures, you can significantly reduce the risk of ants returning to your home. Remember, prevention is key to long-term ant control with salt or any other natural ant repellent.
