The opening video at the top of this site shows a Africanized bee's stinger entrapped in human skin. Under usual circumstances, the result is discomfort for the human but death for the bee. An extremely aggressive Africanized bee colony may attack any 'threat' within 100 ft. and pursue for up to one-fourth a mile. Avoid other people, or they too will be attacked. The Africanized bee swarm will wait for you to surface.
Some people are allergic to bee stings causing anaphylactic shock.
Since Africanized bees attack and sting in great numbers, it is possible that an allergic response may be triggered. An Africanized Bee is more defensive than a normal honeybee and to the casual observer they look the same. A European bee colony produces five times more honey than a Africanized bee colony. Color size and shape are traits that bees pass along from generation to generation through genes contained in cells. The Africanized bee is a dangerous hybrid, passing down the trait of defensiveness to each offspring.
