Put some of it where you see ants. It will kill them.

try equal parts of borax and sugar. If dry doesn't work, add water to make a paste. Spread where you see them. They'll take it back to their hills

Hi Melissa, Have you tried dialogue? Just kidding, if these black ants are what I assume them to be, carpenter ants, you really have no other choice but to kill them off with poison. Is your concern about children or pets? If so, the means of eradication is "injecting" the poison into the wall or ceiling area within their travel pattern. It may take some time to determine this, you'll have to watch their coming and going until you see their most common place they "disappear". This is where you would spray ant poison into that crack or crevice. The aerosol can will come with a detachable "straw" to facilitate this.
