The Wasp Queen is the boss of the Infested Ruins.
The Wasp Queen spawns and approaches from the northeast corner of the map on Campaign Mode. She attempts to get into melee range of her target, slicing them with her sharp appendages. From a distance, she either shoots a homing stringer or 'vomits' out a spread of poison spit balls. The former causes continuous poison damage overtime to whatever heroes or defenses hit. The queen can also summon wasps to her aide.
- In real life, like bees, every colony of wasps has a single queen who is responsible for laying eggs inside their nest.
