Maggies Farm Ant Killer 1 oz. and/or any ant bait at all takes time. That's great news the ants are taking the bait. They will take the bait back to where the colonies are. Thus, the active ingredient will spread and kill off the colony. Please allow at least a couple of weeks for a large decrease in population.
