I don't do it! Sure, I suffer some bites here and there, but it's the price you pay for having these little soldiers clean up the yard and aerate the soil... Do they steal my seeds? Not that I've noticed- I lay down enough to share though. Do they farm aphids? I don't think so. If they do- they're probably just factory farming some snacks for other creepy crawlies that hang out around the yard.
Now, they used to bother me when I first moved into my house. In fact, I used to have all sorts of nasty bugs that bothered me. I'd dig a hole and a nasty grub resembling slimy alien larva would pop up smiling. 3 inch long roaches would crawl up my window screens and dare me to do something about it... Gosh, one thing after another back then.
My yard before I moved in used to be sprayed with pesticides religiously. Serious, I think it's a Catholic thing- go to church on Sunday, come home and kill God's creatures... My earth was fertilized with chemicals and salt based nutrients too, which wasn't helping much. I put a stop to these practices. Which means, that yes, I lived with ants torturing me and attacking the nectar of my veggie blossoms all last year. I'd snip an okra and get a handful of ants- it made posing for sexy Facebook self portraits of me with my veggies difficult to achieve. But I kept a stiff upper lip even with welts and stings.
It's been a year and a half or so... after playing live and let live with every gross creepy crawly unless it tried to bunk with me- my bugs issues seem to have died down on their own. I didn't have any ant problems at all this year- even though I planted their favorite snack- okra blossoms. I think I suffered maybe 3 or 4 bites all together, and really I was asking for it. I actually keep finding a lot of mantis which is cool, very little white fly damage, very few aphids... though I did get squash bugs in the spring- but not in the fall (squash bugs are the bed bugs of the garden, I'd comment more, but I have PTSD).
In conclusion, I say let the ants do their thing. Let all those nasty little bugs do their thing. Plant polyculture beds, practice no till gardening and see what kind of bugs hang out. Oh, and feral cats will kill the roaches. Good kitties!
