Summary
The invasive northern giant hornet, nicknamed the “murder hornet,” has been officially declared eradicated in the US, five years after first being detected in Washington state.
The hornets, which posed significant threats to honeybees and native insects, were wiped out through public cooperation, trapping efforts, and innovative tracking by researchers.
First spotted in 2019, the hornets decimated bee hives and could deliver dangerous stings. Four nests were destroyed in Washington by 2021.
Officials remain vigilant, though no confirmed sightings have occurred since 2021, marking a rare success in invasive species control.
It’s a very easy way to contribute to environmental protection as a citizen. You should definitely tell the authorities. I am not from the US but I guess you can write a Mail to your local environment agency, no need to call the police.
