I have used borax, mostly on fleas. I think weed pulling is therapeutic. Husband just weed whacks. I would rather pull them and be done until the next bunch show up.The weeds will be there tomorrow. Sounds like a nap would be better use of your time. Well, at least more enjoyable!
Google borax ant bait (or boric acid ant bait). Cheap and easy to make and they take it back and kills the whole nest.
