The short answer is yes — ant baits work, but they require a lot of patience. Ants are very fussy eaters. In the morning, the colony may want protein; in the afternoon, the ant colony may want carbohydrates. Understanding this means putting out 2 or 3 different kinds of ant baits to appeal to the colony at all times. Most ant baits come in a 5% concentration, but this strength is too high. The ants usually die before they make it back to the nest. An ideal concentration is between 1% - 3%. Yes, ant baits do work, but they have limitations and results are not instantaneous.
