    I do not know for sure if it will work but others have said boiling water.

    I have tried everything and the only thing that has worked for me is vinegar!

    Medina Orange Oil. 2oz in a gallon of water.

      Do you spray this or pour a small amount on the hill?

    Someone posted a tip about killing ants. She suggested using a spray made from sugar and boric acid. They're drawn to the sugar and then they bring back the poison and it kills the hill. I think you can also just sprinkle the powdered boric acid directly around the affected area.

    I mix it in a watering can. Bucket works also. Pour the whole gallon on the hill, starting in the middle. That is where the queen will be. Then work your way out to the edges. I only use organic materials/solutions. I have used this method for the last 3 years to kill fire ants in my yard. I have not seen any ants at all this year. You can treat the hills as many times as necessary. It won't hurt anything. It may burn the grass some, but will come back. https://www.dirtdoctor.com/garden/Ant-Fire-Ant-Control-Video_vq4088.htm

    Boric acid works, but you typically have to go buy it. We had these "sugar ants" coming up through our paving stones. Home Defense and other sprays just convinced them to move a few feet away. The ONLY thing that worked first time and finally was a mixture of Powdered Sugar and Baking Soda (usually in every kitchen cupboard) sprinkled on and around their mound. The sugar attracts them but the baking soda reacts with the formic acid (the stuff that burns and itches when they bite you) inside of them and kills them. We haven't seen them in our pavers since. That was 2 months ago. It's also safe for kids, other animals and pets. Phil

    I used diotomaceous earth in a sqeeze bottle and squeezed a small amount where they were coming through on my brick walkway. They have not returned. I picked it up at the garden and feed store.

    I killed all of mine with pots of boiling water just like our pioneer women did. Worked like a charm.

    I use corn meal. Safe for animals. Not for ants, they take it back to the nest also. Works good in the house too. Found this on Pinterest.
