You can find killer bees in north and south america,but originally they came from southern Africa. They are called killer bees because they attack anyone who comes near their hive,and over 1,000 people have died this way in the last 50 years. They become angry easily and are not scared of people. They can even chase their victims for up to half a mile. They only sting once. Female bees die after stinging, but during an attack hundreds and thousands of bees sting at once.
