I don't mind the normal ants either. I always used to have these teeny-weeny little ants get in my dry catfood barrel at my old barn but I didn't mind them coz they didn't bite and they let me know that the fire ants weren't in there. One time I wasn't paying attention to the size of the ants in there and scooped up a handful of catfood and got a handful of fire ants with it. Not fun! I'm sure I did a really funny looking dance trying to get them off and it took a week or so for the blisters to go away! So far I haven't had trouble with them getting into the feed room at the new barn.
One more good thing about having ants in the barn is that my barn cats never got fleas. I guess the ants were eating the flea larva.
And there is always a chance, babies might not inherit the gait. As bad as breeding Appaloosas or any color breed. The chance you take.
