This and the gel bait. Works great and if you want you can also buy a spray to do the perimeter. I got this directly from a professional pest company owner. This is what they use and you can't find it in your local stores. Make sure you use something that the ants bring back to their home, because if you only spray the perimeter it won't kill them they'll only move.
