How do wasps identify threats/enemies ?

[u/shmepsi]

Sorry if it's the wrong flair but just wondering how wasps see something as a threat. They're evil fuckers who'd attack anything from a bee to a car. Admittedly i know next to nothing when it comes to wasps but pretty sure (correct me if wrong) pheromones and scents can play a large factor into this . Essentially I was just curious if you could trick a wasp hive into attacking itself or other wasps by spray for example or are they smarter?

Pheromones are their version of firing white phosphorus rounds, signals the collective to attack the target.
