Does Epsom Salt Get Rid Of Ants? Ants can be quite a nuisance when they invade our homes and gardens. They find their way into everything, from kitchens to yards. While there are various methods to combat these pesky insects, one unconventional yet frequently discussed approach is using Epsom salt. In this article, we will delve into the question: Does Epsom salt eliminate ants? We’ll explore the science behind it, how to use it effectively, and whether it’s a reliable solution.

The Science Behind Epsom Salt and Ants

Epsom salt is a natural mineral compound chemically known as magnesium sulfate. It has various applications, including gardening, beauty, and even health. Regarding ants, Epsom salt is believed to work by creating an unfavorable environment. It can absorb moisture, making the areas where it’s applied dry and uncomfortable for the ants. Moreover, the magnesium content can disrupt their scent trails, which ants use to communicate and locate food sources. You may be interested in this also: Can Ants Build Nests In Walls?

Using Epsom Salt to Repel Ants

  • Indoor Use
  • Outdoor Use

Indoor Use:

If you’re dealing with ants indoors, follow these steps to use Epsom salt effectively:

  • Locate Entry Points: Identify where the ants are entering your home. Common entry points include windows, doors, and cracks in the walls.
  • Create a Barrier: Mix equal parts of Epsom salt and water to create a solution. Dip a cloth or sponge into the solution and wipe down the entry points and areas prone to ant activity. It creates a barrier that ants are less likely to cross.
  • Sprinkle Epsom Salt: Sprinkle a thin line of Epsom salt along windowsills, doorways, and other potential entryways. Remember, a little goes a long way.

Outdoor Use:

For outdoor ant control, try these methods:

  • Sprinkle Around Anthills: Locate anthills in your garden and sprinkle Epsom salt directly on and around them. It can deter ants from the area.
  • In Flower Beds: Spread Epsom salt around the base of plants and flowers prone to ant infestations. Be cautious not to overdo it, as excessive salt can damage plants.

Effectiveness of Epsom Salt on Ants

While many anecdotal accounts exist of Epsom salt successfully repelling ants, scientific evidence is limited. Some factors that influence its effectiveness include the type of ant species, environmental conditions, and the severity of the infestation. Epsom salt might work better as a preventive measure or with other ant control strategies.


Is Epsom salt safe for pets and children?

Epsom salt is generally considered safe when used as directed. However, keeping pets and children away from treated areas is advisable until the salt has dissolved or been absorbed.

Can I use table salt instead of Epsom salt?

While table salt might have some repelling properties, it’s not as effective as Epsom salt. Epsom salt’s magnesium content is believed to play a role in deterring ants.

How often should I apply Epsom salt to keep ants away?

The frequency of application depends on the ant activity in your area. Sometimes, a single application might suffice; in others, you might need to reapply every few weeks.


In conclusion, while Epsom salt has gained popularity as a potential ant repellent, its effectiveness is not guaranteed in all situations. It can be a valuable tool in your ant control arsenal, especially for minor infestations or as a preventive measure. Remember that Epsom salt is just part of an integrated pest management approach. Maintaining a clean living space, sealing entry points, and addressing moisture issues are equally important in preventing ant invasions. If you’re dealing with a persistent or large-scale ant problem, it’s best to consult with pest control professionals to determine the most suitable and effective solution.
