Tempo 1% dust is the most effective dust to treat for hornets and yellow jackets. Be sure to treat in the times of the day when they are less active (earlier morning or later evening). You may also want to use a ready-to-use knockdown insecticide such as PT Wasp Freeze II. This spray will spray up to 15 away for safe and quick knockdown of flying, stinging insects.
