Big black ants have decided my vegetable garden is a good place to live. I do not agree. Will diatamacious earth fix this, ie, kill them all? I really, really, REALLY do not want to try and dig them up, like my mother suggested. They big, and if you step on their mound, they swarm out and it just disgusts me. So, can I just sprinkle the diatamacious earth on them? Please advise.
