We first published it on our website in 2017, then also added it into the eBook.

It is cheap and easy to make, and you can spray it on ants inside or outside.

Ingredients for easy homemade ant spray:

2 cups of vinegar, distilled

2 cups of water

3 tablespoons Dawn dishwashing liquid

3 tablespoons table salt

Spray bottle

Mix ingredients together and add to spray bottle. Shake well before spraying each time.

(I use blue Dawn for all my solutions on Chemistry Cachet because it has worked better for me. You can use any dishwashing liquid you have on hand, but I prefer Dawn.)

How to use it:

Saturate the area where the ants are crawling. They die in a few seconds. Make sure to spray the entire pathway they have used as well.

Allow the ants to die, then wipe the area off with a paper towel. The lingering vinegar and dish soap scent deters them from coming back to the area.

Make sure to wipe surface to prevent any possible residue.

This homemade solution in based on science. You can read our blog post here to learn why vinegar, salt, and dish soap make a great ant killer.
