Easy Solution to Kill Ant Piles – Club Soda!

Today’s post is short and easy, which is sometimes just what we all need! Did you know you can knock out an entire ant pile with just club soda? Yup, it’s true!

Kill Ants with Club Soda - Easy, Cheap and Non-Toxic!

When we first moved into our new house this spring, my kids were out playing in the driveway and they started to scream. I went running over to see my son’s legs covered in little black ants and then saw a huge ant pile next to him. Thankfully, some apple cider vinegar anti-itch rub helped the swelling and itching, but I knew I had to take care of the ants. Of course, it had to be a natural solution because I don’t want to spray poisonous chemicals on the ground, which only contributes to harming the environment, animals, and us humans.

I discovered that club soda works because it the carbon dioxide from the carbonation displaces the oxygen in the colony, suffocating the queen, which eventually kills the whole colony.

Kill Ants with Non-Toxic Club Soda

It’s Super Easy and Safe

  • For one medium mound, you need about 1/2 liter of club soda (carbonated water). For a large one, I’d use a whole liter.
  • Pour directly onto the mound – I poured all over the entire mound and not just in the center as it was suggested to me. I generously poured it on, since it’s cheap and non-toxic.
  • It takes about 2 full days for it to all die. One very large pile I had needed an extra dose of soda, and that did the trick. Once it dies, it will just be a mound of dirt, then grass or weeds will start to grow on top of it. I can’t even tell where the mounds were a month later!

I read on several sites that it doesn’t work to kill fire ants. I’d like to disagree. I found that their colonies are harder to kill than black ants BUT I did finish them off with my magic powers club soda. It took two rounds and a liter and a half, but they did DIE.

Now my kids can play without getting bitten by nasty little ants and no eco-systems, other insects, animals or humans were poisoned to accomplish that. Plus, for about $1 a liter, it’s also cheap!

    I’m looking for something to kill weeds that keep growing in my flower bed. I pull them up, put some pre-emergent as instructed and nothing helps. Do you have anything for weeds without harming the plants, flowers?

    • 1 cup of salt, 1 cup of Dawn dishwashing liquid, and fill the rest of a milk jug with white vinegar. Get a Windex bottle and fill it half way with water and the rest up with your vinegar solution. Spray everything you want dead. Do not get this stuff on your plants. This is a vegetation killer. Your pre-emergent only works on seeds that have not started growing yet.

  2. Hi Sara:

    Have a problem with air potato vine growing in our backyard which is bordered by a preserve. Can you recommend a solution to rid the vine as well as the roots?

    Thank you,

    Well this is a new trick! Good thing I searched carefully for this one. Definitely going try this one out! Thanks for sharing this trick.

    I have used grits to get rid of ants. Here in Alaska, we get big carpenter ants. They eat the grits, it swells in their body, and proof. No more ants. I’m going to try the club soda next. It sounds like it works a lot faster.

    I want to have a try and expect it can do me a favour.谢谢!

    Don’t use grits or rice if you have a lot of outside birds. I did the rice thing an we lost all our birds for a whole year!!!! I felt awful.

    Great blog. For the past couple of months, huge colonies of ants have started to raid my backyard. The mound looks huge and I didn’t want to use poisonous chemicals as my kids and pets spend most of the time playing. But as soon as I came across your blog, I saw the perfect solution for my problem. Thanks Sara, you are definitely a life-saver.

    • Please don’t forget that diatomaceous earth is non toxic , especially food grade that is sold in grocery stores , It kills the ants by damaging their exoskeleton .

  8. Help! I have emptied four liters of Club Soda in two days into our backyard ant hill – and the ants are still there! What am I missing here?!

    • Hi Marilyn! I’m not sure…it worked very well for me. But there are a lot of other suggestions here in the comments that have worked for others. Some have tried cornstarch and Borax, too, and have said that works, too.

  9. Celeste I says:

    try cornmeal, works great. Dries out ant hill.

  10. Did not work for our hard to kill vicious little fire ants here in Texas

  11. Does this method kill fire ants or just the regular black ants…I have red ants in my garden and they need to go!!! Thx!

  12. Tried the club soda on three different ant hills. Various sizes small to large. Did nothing.
