As something of a beginner myself...this is far from expert opinion, but....
I haven't had any trouble with ants in my garden....as matter of fact, I planted one eggplant right on top of an anthill (didn't realize it until the hole was dug, i guess

) and it is doing very well weeks later.
I did have aphids on my snow peas, and the ants were "herding" them, but once the aphids were gone....no more ant trouble. I mostly don't worry about them unless they are fire ants (ouch!!)
Could be wrong, but it doesn't seem like they are causing trouble.....
