The 'murder hornets' are back in the news after the first nest was discovered in the United States.
The insects don't attack humans, directly - but even a small group can decimate a honey bee hive in a matter of hours. That's bad for humans because honey bees help pollinate the crops we utilize and eat.
Tracking radios were placed on a handful of the invasive hornets after they had been trapped.
The large insects then led entomologists back to the nest, located inside a tree in Blaine, Washington. Officials plan to destroy the nest Saturday.
