AP News reports that a particularly dramatic “invasive exotic” species – Vespa mandarinia, the Asian giant hornet, better known as the “murder hornet” – has been eradicated in the U.S., thanks in part to tiny radio tracking devices:
The Washington and U.S. Departments of Agriculture announced the eradication Wednesday, saying there had been no detections of the northern giant hornet in Washington since 2021.
The news represented an enormous success that included residents agreeing to place traps on their properties and reporting sightings, as well as researchers capturing a live hornet, attaching a tiny radio tracking tag to it with dental floss, and following it through a forest to a nest in an alder tree. Scientists destroyed the nest just as a number of queens were just beginning to emerge, officials said.
“I’ve gotta tell you, as an entomologist — I’ve been doing this for over 25 years now, and it is a rare day when the humans actually get to win one against the insects,” Sven Spichiger, pest program manager of the Washington State Department of Agriculture, told a virtual news conference.

Northern giant hornets pose significant threats to pollinators and native insects. They can wipe out a honey bee hive in as little as 90 minutes, decapitating the bees and then defending the hive as their own, taking the brood to feed their own young.
