What Kills Ants Instantly Naturally?

What Kills Ants Instantly Naturally

Below are some of the best natural treatments you can try to get rid of the ants invading your space.


Mint has a pleasant minty scent to humans, but not for ants. Ants find mint to be strong scented and steer away from them as much as possible. 

Plant mint around your home to repel ants and other insects, such as bugs. You can also use the essential peppermint oil as a natural way to manage ants.

To use: Put a few drops of peppermint oil on cotton balls and leave them on areas where you frequently see ants.


Vinegar has a repulsive scent to ants, making them run away when they sense it. To use:

  1. Blend a 50/50 solution of water and vinegar in a clean spray bottle. 
  1. Once done, spray it straight to the ants or around your window sills and affected places to eliminate them effectively.

Lemon Juice

Like vinegar, lemon juice scent also erases trails that ants follow to get their food. Furthermore, its acidic smell deters ants from visiting your place more often.

To use: Mix 3 parts of water and one part lemon juice, mix well, and spray it on affected areas. Moreover, spatter some it to entryways and around your property area to prevent ants from coming again.


Cinnamon is another good option for killing ants. Cinnamon can suffocate ants when they inhale it, causing them to die.

To use:

  1. If you opt to use ground cinnamon, sprinkle it directly on the ants’ path or around the anthill entrance. 
  1. If you’re using the cinnamon essential oil to get rid of ants, mix water with a few drops of cinnamon oil and spray it on ant trails, windows, cracks, and around doors.

Cayenne Pepper or Black Pepper

Ants both hate black pepper and cayenne pepper since they find the spices’ scent irritating. To use:

  1. Locate first the source of ant infestation. 
  1. Once found, sprinkle a generous amount of pepper around the area. Although this won’t necessarily kill the ants, it will discourage them from returning.

Food-Grade Diatomaceous Earth

Diatomaceous earth can break down the insects’ exoskeleton, including ants. DE powder is fossilized marine phytoplankton remains that can dry out the ant’s body.

To use:

  1. Sprinkle a thin coating of DE gently on windowsills, under cabinets, beneath the fridge, in and around garbage bins, and any other areas where you notice ant activities.

How Do You Make Ant Poison at Home?

  1. Soak several cotton balls into the mixture, and place them near ant mounds or where you often see these pests.

The sugar draws the ants, while the borax kills them one to two days after consumption. This method can destroy the whole colony as the ants can take the sweet paste to their queen, the one known to deliver more ants. 

Water and White Vinegar

Vinegar is known as one of the well-known insect killers and deterrents, including ants. 

To make:

  1. Get a clean spray bottle and fill it with equal parts of water and vinegar.

What Is the Best DIY Ant Killer?

Some of the best DIY ant killers, such as traps, involve two primary components—one that attracts the ants and one that kills.

Note: While boric acid is not a traditional pesticide, it can potentially be dangerous for pets and kids when ingested. So, make sure to put it out the reach of kids and pets.
