Need some help or suggestions for killing some ants that have taken up residence in a planter, under my brick path and I think in some of my sod beside the path.
My husband has torn up some of the path to find where they are coming from and has also had a little fun with gasoline and a lighter. I have tried Borax as I heard they like to eat this and it kills them, I have mixed it with sweet things too in hopes they will like it (which they don't seem to care for either way). Also have poured several pots of boiling water on major gatherings and points of entrance/exit.
Any other tips?
