Little known facts about "killer bees":

The bee known as the "killer bee" – the Africanized Honeybee – attacks in large numbers and they have been known to chase intruders for over a quarter of a mile when disturbed. 

Their venom is no more dangerous than regular honeybees, but because they attack in greater numbers, your chance of having a severe allergic reaction when they sting you is increased.

The "killer bee" lives in South America, the western and southern USA.

Each bee can sting only once because their barbs are hooked and when they fly off part of their abdomen is ripped off including the stinger.

(Regular honeybees also can only sting once and then they die, unlike bumblebees or carpenter bees, which have smooth barbs).

The queens were originally brought from Africa and Tanzania, but the Africanized honeybees have spread throughout the world.

Because of their aggressive nature, it's recommended that you call in a professional exterminator to get rid of their nests.
