Getting Rid of Tiny Ants?

I seen people saying apple cider vinegar works to get rid of the tiny ants. I was wondering if it really worked and have also seen people saying peppermint oil, would peppermint extract work? We can't tell/see where they are coming from because of the way our kitchen is built/setup. I am using the baking soda/powdered sugar trick and they are running away from it, it seems they are attracted to water only, from what we have tried.

So I was wondering if the apple cider vinegar and water, or apple cider vinegar and peppermint extract would work? or even peppermint extract with water. Please help! I am getting annoyed with the ants, seeing as how they are in the kitchen and taking over. And we don't have very much money, so I am trying to use what I have to kill the ants and keep them away.
