I am in the same boat here in Orangeburg SC so I will be waiting for a solution as well
I am beginning to think the hill i live on is an ant hill also. I have .70 acres and I also have .70 acres worth of ants. You can barely see the ant hills as they seem to live in the ground. They are everywhere. If you go outside you absolutely cannot stand in one spot for more than 3 seconds. When you look at the ground all you see is ants running everywhere but nowhere at the same time.
I have found a way to avoid the bites but you will look really really odd
my solution is leather boots
this past weekend i had to plant 3 peach trees, 1 lemon tree, and a plum tree and I started with one peach tree with friggin flip flops on and got bit up. So got to thinking maybe if i change my shoes that will work. The best option that came to mind was my leather high heel knee high winter nine west boots. mind you it was nearing 100 degrees so i had a bathing suit top on and daisy dukes.
Thank goodness i live aways away from the highway. Out there planting trees in a blue and tan bathing suit top pair of daisy dukes and my expensive knee high leather winter boots but guess what I DIDNT GET BIT with the boots on. my mom was SO ASHAMED...but that made it even more fun.
