I wanted to follow-up on this thread.
1st - Thank you to everyone who replied.
I tried several recipes this summer to see which the Ants preferred. The one I found that works in my area is as follows: 1 part honey, 2 parts water, & 1 part borax - heated and stirred till everything is dissolved. I place a tablespoon or 2 into jars, and drilled .201" diam holes in the lids. I placed about 20 jars strategically around the prooerty in Ant-Problem area. The ants seemed to like this a lot. I would estimate that Ant activity is down by 80%+ over the course of the summer.
All recipes with borax & sugar, or corn syrup failed miserably. They never touched it.
We had our first good rain (a little early) a couple weeks ago, and a 2nd rain last night - usually after the first rain of the season, the ants come pouring out of the ground by the millions (billions?) to die. I have not seen an Ant after either rain - so, keeping my fingers crossed. Trees that were covered with ants year-round now seem to be nearly devoid of them (silk trees, curly willows, etc). I will continue to monitor them.
So ... hoping this helps someone ...
