This quest is started at the Ancient Wardstone in the chamber behind Queen Maelign.
Objective: Bring 8 Workers or Soldiers to the queen.
You have a transmogrify on you, about 3 minutes worth, of a queen ant. More than enough time. The soldiers will have green names but the workers will still be yellow. Find one, target it, hit the pheromone and they will follow you. Take them to the queen's corpse that started the quest.
