Bees have a barbed stinger at the base of their abdomen which carries their venom.
The bee forces the tip of the stinger through the skin of the victim and leaves the stinger, poison sack and attached muscle in the victim's skin. It may take hundreds of bee stings to inflict a fatal toxic dose of venom in a healthy adult. Although their sting is treated the same as other bee stings, these bees are very aggressive and much more likely to attack when threatened. The venom sac attached to the stinger may continue to inject venom even after the bee has flown away. For many years it was recommended that bee stingers be removed by scraping, the fear was that pinching or tweezing may squeeze more venom into the wound.
