Murder hornets from the first nest discovered on US soil have been successfully sucked out of a tree cavity and placed on ice after experts located the nest in Washington state this week by attaching radio trackers to the bugs. The so-called murder hornets, known for their potentially fatal sting to humans and their ability to wipe out an entire bee hive in a matter of hours, were vacuumed out of the tree into a long plastic tube before being killed, marking the culmination of a complex removal process Saturday morning.
