Thanks to all who replied to my ant problem. I found something that works by accident.
My lawn guy kept cutting up my veggies and I was about ready to cause him physical harm and my son wanted me to not pay him!!

Anyway, to sort of show him his boundaries, I put down a layer of newspaper about 4 feet wide all the way around and 12 papers thick and we put pine bark mulch on top. I only put it around one bed because he wasn't hurting the other ones. It rained and the ants boiled up out of the ground into the other two beds that didn't have the papers but didn't go near the one with the papers. The cooperative extension service here suggested that they didn't like the added moisture of the newspaper and went to "drier ground".
