What are murder hornets?

Sounds awful. Are they really all that bad?

Asian giant hornets, terrifyingly nicknamed "murder hornets," are really nasty creatures. At up to an inch and a half in length, they're the largest hornets in the world. They prey on beehives, decapitating their victims and then sticking around to eat the immature bees in a horrifyingly named process called "slaughter and occupy." Murder hornets, indeed.

Their sting is very painful to humans, but they don't typically bug people unless they're provoked. The bigger concern with their introduction to America is that they threaten bee populations that are already on the decline. Asian honeybees have defenses against the murder hornets—if one gets into their hive, they gather around it and vibrate their flight muscles, making too much heat and carbon dioxide for the hornet to survive. This defense gets the deceptively cute nickname of "bee ball." Honeybees in the U.S. don't make bee balls, however, and are thus really vulnerable to the murder hornets, which is why beekeepers are trying to get rid of them.

What else can I help you with?
