Inside: Finally, a homemade ant killer recipe that’s safe to use around kids and pets!
If you live in a warm climate, then chances are you’ve dealt with pesky ants. Whether they’re sneaking onto your countertops or terrorizing your garden, ants are super stubborn and hard to get rid of. That’s why this natural ant repellent spray is so amazing— it’s safe, easy, cheap, and IT WORKS!
DIY Ant Killer (That Works!)
Last Valentine’s Day, an army of ants invaded our bedroom. A small box of candy had fallen behind one of our nightstands, unnoticed, and by the time we figured out what the ants were after, they were well settled into their path.
I tried all sorts of things to get rid of them, from bleach to strong commercial cleaning sprays, but they always came back. Then I did a little research for natural remedies and put together this homemade ant killer spray. And it worked!
The best part about this ant killer recipe is that it is safe to use around kids and pets (unlike a lot of the toxic store-bought varieties or other DIY recipes that use borax).

Note: One of the most common reader questions I’ve gotten from this post is “what about roaches?!” Here in the south, roaches are a thing, whether or not you have a messy house! That definitely came as a shock, but you can do things to keep those yucky roaches in check. Try our new 2-ingredient natural homemade roach killer too!
How to Make Non-Toxic Ant Killer
First, watch the video to see how it’s done, then keep reading for full supply list and step-by-step instructions.
Watch this quick demo video to see how we mix our ant spray without making a mess:
Homemade Ant Killer Ingredients
For your convenience, I’ve provided shop-able ad links to products used to make this natural ant repellent spray; read our disclosure policy here.
- 2 cups apple cider vinegar
- 2 TB dish liquid
- 2 TB baking soda
- Fill the rest with water
Ant Killer Recipe Directions
- Combine vinegar, dish liquid, and baking soda in an industrial spray bottle. Add water as needed to fill the remainder of the bottle.
- Make sure you mix this ant repellent spray over the sink — when you add baking soda to vinegar it creates a lot of foam! I add ingredients slowly, allowing foam to settle before adding more. (Kind of like pouring soda over ice). Another way to avoid a mess is to mix in a bucket and then pour into a spray bottle.
- We use a large industrial spray bottle because they don’t clog and they last longer than the cheapie bottles. I can’t even tell you how many cheap plastic bottles I’ve thrown away in the past. The industrial bottles last for years though!
A printable copy of our non-toxic ant killer recipe is available at the bottom of the post.
Suggested uses for this homemade ant repellent spray:
- For indoor use — Simply spray over the entire area where ants have made their path and wipe clean. You can spray and let sit over entry points to keep the ants from coming back.
- For outdoor use — Apply a thorough coating over plants and surrounding dirt. I’ve used this spray on our outdoor plants with great success. Ants seemed to enjoy our lime tree, but not anymore! (Note: Always spot test first to make sure that your plant is not sensitive to vinegar)
This is such a simple concoction, but it works so well — and it smells nice! Even better, you don’t have to worry about getting harsh chemicals everywhere (definitely a plus in a house with kids and/or pets!)
Printable Copy of Our Homemade Ant Killer Recipe

June 9, 2015 at 11:05 pmWhat about spraying where cats will be? How safe is it?
Stacey aka the Soccer Mom says
June 10, 2015 at 11:26 amEverything is natural and non-toxic– plus I would imagine that cats would have zero interest in eating vinegar 🙂 I had a cat when I first tried this stuff and he could’ve cared less about what I was doing.
Donna says
July 8, 2018 at 12:28 amHi Stacey/ I came across your blog from back in 2015 on vinegar, dish soap to kill ants. Won’t the dish soap harm pets?
Stacey aka the Soccer Mom says
July 16, 2018 at 1:55 pmThe spray dries quickly and you can wipe away any excess. It doesn’t leave a harmful toxic residue like many bug killers made with poison. I would imagine that most pets would stay away from it anyways because the vinegar smell 🙂
Lily says
March 5, 2019 at 5:15 amDon’t use Baking soda /ACD you will kill your plants, I lost my plants all burnet , because stupidity of people posting wrong things
Stacey aka the Soccer Mom says
March 5, 2019 at 10:50 amI’ve used this spray on our plants, with no ill effects. In the directions I do recommend spot testing first, as some plants may be more sensitive that others.
Mandy says
June 13, 2015 at 1:46 pmCould I use white vinegar?
Stacey aka the Soccer Mom says
June 13, 2015 at 1:55 pmI would imagine that would be fine too– I used apple cider vinegar for my first batch because that’s what I had on hand. Since it worked, I stuck with it 🙂
Stephanie Smith says
July 1, 2015 at 11:15 amThis is a relief. I’ve been battling ants in my kitchen the past several days. I’ve been trying to find a treatment that will work and keep them away, but I swear, the second my husband drops a chip they’re on it in seconds. I happen to have all these ingredients as well, so I’ll make this mixture when I get home and give it a shot. Thanks for sharing!www.stewartspestcontrol.com.au
AMANDA says
July 21, 2015 at 6:00 pmOk I’m not sure what I’m going wrong but every time I add baking soda to the apple cider vinegar/water/dawn dish soap mixture it starts foaming/pouring out of the bottle. I put the lid on the bottle and noticed that the bottle was getting round. I loosened the lid and it exploded!??? Please help!!
Stacey aka the Soccer Mom says
July 21, 2015 at 6:52 pmHi Amanda, try adding the baking soda bit by bit. Everytime it starts to foam up, stop and let the bubbles go back down before adding more baking soda. (Kind of like if you were pouring soda into a glass of ice.) I always mix over the sink just in case, but if you go slowly it should be ok.
Cathy says
February 22, 2016 at 12:30 pmYes mine exploded everywhere too! I ended up putting everything in a large bucket to mix then transfer to spray bottle. I live in Ohio, we have had a mild winter. I’m just starting to see some ants, it is earlier than normal so I’m hoping once the weather really warms up I won’t see any! I’ve used the corn meal, sugar, water paste mixture to attract them and they are supposed to take the “food” back to the nest and eventually it kills the colony, but it takes so long, and it’s disgusting how many ants come and cover the mixture. thanks for this recipe!
Stacey aka the Soccer Mom says
February 22, 2016 at 4:13 pmThe mixing bucket is a great idea– thanks for sharing Cathy!
Jacob Searcy says
April 19, 2016 at 2:54 pmThis is a LIFESAVER. I came home and there were ants all over my kitchen, but I just made this in a minute, put it all the way around the door. One more tried to come in and turned right back around. Thanks so much
Stacey aka the Soccer Mom says
April 19, 2016 at 5:03 pmAwesome! So glad you were able to keep them out!
Dana says
April 24, 2016 at 2:56 pmHow often do you have to re-apply it?
Dana says
April 24, 2016 at 3:00 pmAlso if an ant walks into it after the area has been sprayed will it still die, or does every any need to be hit directly?
Stacey aka the Soccer Mom says
April 25, 2016 at 12:30 pmThey usually die when they walk into it, or they will turn around and attempt to avoid the spray. If you hit them directly it works almost instantly.
Stacey aka the Soccer Mom says
April 25, 2016 at 12:30 pmI reapply as needed, if I see ants again. Sometimes it gets them the first time, sometimes they are pretty determined and I might need to apply a second time. It also helps to find where they are entering the house and spray outside as well.
Ashlee carlisle says
May 21, 2016 at 7:29 pmI used this on my vegetable garden and it burned my plants ?, looks like they’re dying now .
Stacey aka the Soccer Mom says
May 22, 2016 at 1:24 amI haven’t heard of this happening with this formula, but maybe it is possible that some plants are more sensitive? I’ve used this spray on my lemon and lime trees, as well as my herb garden with no ill effects.
Wiley says
November 8, 2016 at 3:49 pmVinegar is an effective weed killer when used at full strength, so if tender or sensitive plants are soaked with even a diluted mix of vinegar, they may suffer or die. That shouldn’t happen if the soil is wetted, and most trees or bushes shouldn’t be affected.
Kristie says
August 29, 2016 at 10:35 amWhich Dawn is this? Have you always used the red one or tried another.
Stacey aka the Soccer Mom says
August 29, 2016 at 1:27 pmHi Kristie – To be honest, I can’t even remember. I just use whatever I have on hand 🙂
Brenda says
December 11, 2016 at 11:27 amWill this work to keep ants away from ankles and feet and keep them from stinging if sprayed on the skin directly?
Stacey aka the Soccer Mom says
December 11, 2016 at 12:42 pmHi Brenda – I’m not sure how it would affect skin. Nothing in the spray is harmful or toxic. My only concern is that vinegar is acidic and perhaps might irritate sensitive skin if sprayed directly on it. I’ve only used this spray on household items and plants.
Barbara Spillers says
June 27, 2018 at 2:24 pmWanted you to know I made this ant killer and realized it is a great cleaner too. Thanks,
Stacey aka the Soccer Mom says
June 27, 2018 at 5:58 pmWonderful! Glad you found it so helpful!
Terry says
July 4, 2018 at 3:22 pmIs this effective for cockroaches as well?
Stacey aka the Soccer Mom says
July 5, 2018 at 11:38 amHi Terry – I haven’t tested this out specifically on cockroaches. They’re usually pretty fast and resistant to almost everything except smashing, but it could be worth a try!
Cheryl says
July 13, 2018 at 6:06 amSo if I mixing this in a bucket how much water am I adding?
Stacey aka the Soccer Mom says
July 16, 2018 at 1:51 pmI would mix all ingredients except water in the bucket, then slowly pour into your squirt bottle. Then you can top off the remaining space in the bottle with water. Hope this helps!
Yvonne says
July 20, 2018 at 5:32 pmWe came home from our Yellowstone vacation to find ants everywhere in our kitchen, refrigerator and even freezer. I looked up natural remedies and seen your recipe. It’s a true miracle this recipe works!!! I’ve tried natural and the regular poison stuff and nothing ever works. My husband said that stuff you made was a miracle. Thank you for this recipe! I don’t ever have to waste time/money on other stuff. Ants are dead now, thank goodness.
Stacey aka the Soccer Mom says
July 21, 2018 at 3:42 pmWonderful! I also found that many of the store bought ant killers didn’t actually do the job, which is what led me to experiment and create this natural ant spray to begin with. Thank you for letting me know it worked for you!
Lee says
March 24, 2019 at 9:59 pmHi! Any idea if this is safe on hardwood floors? Thanks in advance!
Stacey aka the Soccer Mom says
March 24, 2019 at 10:41 pmIf they are sealed, it should be ok, but to be safe, I would definitely spot test on an inconspicuous area first.
Kate says
May 7, 2019 at 2:23 pmHi. When you say wipe clean, is it with a wet rag or a dry one?
Stacey aka the Soccer Mom says
May 7, 2019 at 7:49 pmI use a dry rag or paper towel, just to dry the excess liquid.
Eden says
May 12, 2019 at 8:14 pmThank you so much! It worked almost instantly!
Stacey aka the Soccer Mom says
May 13, 2019 at 1:02 pmWonderful! I’m glad to hear that!
Mickie says
May 26, 2019 at 7:10 amOh my goodness! I made the spray EXACTLY like your video directions! I had no problems with the bottle exploding or anything like that! I sprayed it ONCE between my patio door and living room and the ants are G O N E finito — although it is a little “slimy” so you do need to eventually mop it up. Thanks so much! It works great.
Diane Edwards says
May 29, 2019 at 3:55 pmHi Stacey,
How large, in ounces, was your spray bottle? Is it necessary to put water in solution?
Thanks,
Diane
Stacey aka the Soccer Mom says
June 1, 2019 at 11:15 amHi Diane, I believe my spray bottle is 24 ounces. But you could use something slightly smaller if that’s what you have on hand – just add less water. I do recommend adding some water to dilute (it will leave less residue), but the other ingredients are of course the most important. Hope this helps!
KB says
June 9, 2019 at 9:13 pmHi-
Out of curiosity, does this just work on the tiny sugar ants or will it also be effective on those stubborn carpenter ants also? Thanks!
Stacey aka the Soccer Mom says
June 10, 2019 at 12:31 pmWe’ve used it on any kind of ants we see – even fire ants! They all hate it 🙂
Steve says
July 5, 2019 at 6:19 amIs it taken back into the nest, killing the ants at the source or does it only only kill the ants it contacts directly?
Stacey aka the Soccer Mom says
July 5, 2019 at 10:29 amHi Steve – This kills ants that it contacts directly and keeps them away from that location in the future. However this is not something that the ants are able to carry back to the nest, as it is a spray.
