How to kill ants using vinegar Dawn and salt and water?

i haven’t heard of the vinegar solution, but two methods are to put a small amount of cornmeal near the ant hill. That feed it to the colony, it swells and kills them. Another way, not good if you have small children or pets, is to mix borax with sugar, then add a little water to make a syrup. Put in a shallow container a jar top and on the floor where you see ants. They take the syrup back to the colony and they all die.

I do not know that recipe, but I do know how to rid any place of ants. Corn meal kills them. They take it to the nest and it kills the colony. We use Jiffy because it is sweet. Put it on a mound or where you see a trail of ants. After you put some out and see a few ants, put more out. It means you have a large colony. We never have to put it out more than twice. I keep Jiffy in my pantry especially in spring for new colonies moving in. After spring applications, I have never had to put out more all summer. An old timer told us this years ago. We had tried everything and this is what works.

That is for killing weeds

I use cornmeal also. Works like a charm ♥

Cornmeal works well. We have also used a product called Terro from the DIY stores, it is a liquid, just put a few drops on the cardboard provided, ants love to ingest it, take it back to the colonies and then they are wiped out.

If this is for outside do not use salt!! No plants will grow in that area due to salt buildup. If they are outside, just use DE - food grade Diatomaceous Earth - cheap, not harmful to pets. If the ant's are inside, clean everything well with a bleach/water solution. And keep everything very clean.
