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 8,000 bee stings is not unusual for a killer bee attack. In face, a student in Costa Rica had 10,000 stings and died. Often, the bees attack for no reason. They may attack because of a strong smell 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.
