I searched online for an ant deterrent where we lived before. We had a swimming pool and outside hot tub. I guess that was what drew them. Anyway, I read that sprinkling cornmeal is the best thing to do for ants. They eat it and swell which kills them. From what I read, it had better results than anything else as far as permanently keeping them away. I cannot even imagine finding that many ants in my BED!!! UGH!!!
