Southern cooking for ant control

[Jo Ann]

I was reading this last summer a book on cheap ideas for gardening they suggested to get rid of ants feed them dry grits. I don’t remember if your suppose to use instant or regular. I’m guessing the theory is after the ant eats the grit and then drinks some fluid the grit will swell up inside it and kill it. Just wondering if anybody else has heard of this. Do you think it would work or would the ants just have a nice breakfast?...
