Bee Stings

First, honey bees are stinging insects. They have stingers, and their sting is painful. However, honey bees are relatively gentle creatures, and they only sting to protect their hive. The craft of beekeeping involves employing techniques passed down over hundreds, even thousands, of years for handling bees. For example, we know from cave paintings that people have used smoke in ancient times to help control the behavior of bees when we “rob” them of their honey. We consider honey bees as being defensive rather than aggressive in nature. Bees will defend their hive, where they protect their food stores and brood, by stinging intruders, whether they are foreign bees, attacking wasps, hornets, skunks, bears, or humans. The honey bee’s sting is barbed. When we are stung by a honey bee, the barbs hold the sting firmly in our skin. As the bee pulls away, her abdomen is torn apart, a fatal injury for the individual bee. The bee’s sting and death, however, have a concentrating effect in protecting the hive. Left behind on the skin are the sting, venom sac, muscles pumping venom, and glands emitting alarm pheromone. Alerted hive bees readily follow the intruder and add more stings.

Honey bees from other hives are the most common attacker of hives. Guard bees at the hive entrance check bees attempting to enter the hive. Since the bees from each hive have a distinct odor, the guards turn away intruders. If a guard stings an intruding bee, her sting usually pulls out of the victim’s soft exoskeleton without fatally injuring the guard bee. Gentleness in honey bees is an inherited trait, and beekeepers select for bees that are gentle. Helping control the behavior of bees is one of the ways beekeepers serve their communities. Even though beekeepers learn how to safely handle bees, it is important for them to always protect their eyes from stings.
