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!

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!

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!)
