Suffering from an ant control problem in your garden? This homemade ant killer is as effective as it is 100% safe and natural! No need for chemicals or expensive treatments – this homemade ant killer recipe is super cheap and it actually works better than most store bought traps. This DIY bait station is also safe for your plants.

Kill the ants once and for all using borax and sugar! Yep, you heard right – a simple combination of borax, sugar, and water will exterminate ants and other small insects that may have taken up residence in or around your home. Ant colonies (even fire ants) will completely disappear after just one application. But how exactly does this borax ant killer work?

It's pretty simple actually? The mixture is borax and sugar, and so naturally, ants are attracted to the sugar. Worker ants will quickly find the sugar mix and carry it back to the rest of the colony. The ant queen will then ingest the sweet (but poisonous boric acid) mixture and she will die, as will the rest of the colony. The active ingredient in Borax, which is boric acid, is what actually poisons and kills the ants. Although the sugar mix attarcts the ants, their digestive system cannot handle the Borax. After a few days, your ant infestation should be a thing of the past.

This is an easy and inexpensive way to control ants and also prevent them from popping up in your home. This DIY ant killer will also work on bigger ants, such as carpenter ants.

There are 3 different ways you can apply this DIY ant killer:

Method 1: Cotton Balls

Soak cotton balls into the Borax mixture until well soaked and place the cotton balls where the ant trails may be. This can be in your home, around your garden, or literally anywhere you have ants! Be sure to place the soaked cotton balls at any entry points where ants may try to come in.

Method 2: Spray

Pour the Borax mixture into a spray bottle and spray onto the ant paths. This will prevent ants from ever coming back, and if they ingest the mixture, they will die. This method is safe for pets and children as well, so no need to worry about harmful chemicals.

Method 3:

Pour the mixture into different corners of your home or your garden (especially around where you think they ants may come from). The ants will ingest the mixture because of the sugar and carry it back to their colony, which will kill them.

This Borax mixture is 100% safe for kids, pets, and plants!

If Borax is not your thing, or perhaps someone in your home is allergic to it, we have a few other favorite homemade ant killer recipes we'd like to share with you! These recipes are all cheap and easy to make, and best of all, they're effective at combating an ant infestation!

#1. Vinegar Ant Killer Recipe

This simple recipe requires only two ingredients: vinegar and water! It's cheap, it's easy, it's fast, it's safe, and best of all, it works! Mix equal parts water with equal parts vinegar and pour in a spray bottle. This recipe is good for a quick elimination solution. Simply spray directly onto the ants and wipe up the mess!

#2. Dish Soap Ant Killer

This is another simple ant killer which again, is cheap and quick to make. Simply mix equal parts dish soap with water and mix in a spray bottle. Spray directly onto the ants and wipe away!

#3. Essential Oil Ant Killer

For a more heavy duty ant killer, try essential oils. Essential oils will not only kill ants on contact, but they can also destroy an entire colony. Mix 1 cup of water, or half water and half vinegar, with about 40 drops of any of the following essential oils:

  • Tea tree oil
  • Clove essential oil
  • Peppermint essential oil

Mix all ingredients thoroughly and pour into a spray bottle. Spray directly on the ends, or anywhere where you think the ants may be entering, such as doorways.

#4. Peanut Butter Ant Trap

Some ants, believe it or not, are not as attracted to sugary substances as others. Some ants actually prefer a more savory meal, such as peanut butter. Mix a tablespoon of peanut butter with one teaspoon of Borax. Now grab a straw, and push that mixture into the straw using a wooden stick. Once the straw is nice and full, cut it into smaller pieces and place where ants may enter, such as doorways.

#5. Cornmeal Colony Ant Killer

If you're serious about killing an entire ant colony, this cornmeal method is the way to go! But, surprisingly enough, it's not the cornmeal that kills the colony – it's a little hidden surprise that's INSIDE the cornmeal mixture, which is Borax. Ants are attracted to cornmeal, so just like the Borax and sugar mix recipe above, they'll carry it back to their colony. Onto a small plate, add 70/30 ratio of cornmeal and Borax and wait for the ants to come!

Homemade Ant Killer
