Want to keep ants away from your kitchen counter, garbage can or away from shrubs or trees or flowers or just about anything? I use black pepper from the kitchen. Just sprinkle it around anything and leave it there, it will deter ants large and small. I haven't had an ant problem since I used it 3 months ago. It works great for me, try it and see if it works. Only sprinkle it lightly inside the house, but a little more for outside.

Have a big problem with ants in my backyard, going to definitely try it!
Do NOT use black pepper if you have cats...it can be lethal to them. I put bay leaves on the window sills, etc.
Me and My Mom did this a few minutes ago, with vinegar and we will see how it works. Trail of black pepper, and sprays of vinegar, so far no ants, it's been 10 minutes.
