Which bee sting hurts the most? Does it depend on the bee?

Bee stings. I don't know which bee stings the worst. But i can tell you from personal experience that it is very important not to agitate a yellow jacket nest. Unlike most bees they are very aggressive when it comes to protecting their nest. Even foot steps near their nest can cause them to swarm. If you try to shoo it away or hit it w a fly swatter it will release a chemical that causes the other yellow >>.
