Ant's in container
I garden in large black nursery pots, way to large to move, and have had very good results, they sit on my concrete patio. Problem is when I was adding compost to one of the pots I found ant's along with eggs. I went ahead and added the compost and really mixed it up good. Now I need to know what I can do to get rid of the ant's. I have to reuse the soil in it, just can't afford to replace it this year. Haven't planted anything in it yet but need to soon.
TIA for any help someone can give me.
Oh, forgot to mention I really prefer not to use chemicals if I can find an organic method.
