Why do wasps sting people?

Back to the second floor, the wasp has no honey. Bees produce honey.

Back to the landlord, the reason why wasps sting people is because animals have a sense of self-protection. It is normal and understandable that people harass it, and it must protect its home and territory.

Sometimes it stings even if people don't bother it. This is because it mistakenly thinks that this person is its danger source, so it wants to drive him away and sting him. Why do you think this man is a source of danger? It may be that their ancestors were harassed and stung by humans, and their ancestors passed this memory on to them. They feel very dangerous when they stab people-to put it bluntly, this is also defending their own territory, but it is a bit too radical. For example, the wasp is in Guangdong, and it can't fly to Guangxi to sting people there, because Guangxi people have not entered its territory.
