Ascend is formulated as an oil bait that functions as an attractant to fire and pharaoh ants. This product is a stomach insecticide which acts to reduce ant workers. The bait is also passed by the workers throughout the ant colony and eventually to the queen.
This product is toxic to ants; however, it is most effective against the ant queen and causes an immediate halt of egg production and disappearance of workers, which leads to the decline and eventual elimination of the ant colony. Apply when ants are actively foraging. This is typically when soil temperatures are greater than 60°F (15°C).
