Killer bees are very dangerous, and people are right to be afraid of them. When killer bees attack people, they attack in great numbers and often seriously hurt or kill people. Four hundred bee stings can kill a person. A total of 8000 bee stings is not unusual for a killer bee attack. In fact, a student in Costa Rica had 10000 stings and died. Often, the bees attack for no reason. They may attack because of a strong small that is good or bad or because a person is wearing a dark color, has dark hair, or is wearing some kind of shiny jewelry.
