I guess everyone is so sick about hearing Covic-19 news that they forgot the Asian Murder Hornet thing HAPPENED LAST YEAR. In fact, as far as I know, as of the publishing of this article, no hives or individuals have been found in the U.S. or Canada in 2020. Now it's still early in the year, so that could easily change. But until it does every article going viral at the moment is just fear mongering or responding to fear mongering.
So here's the issue, lots of these articles are titled something like Asian Murder Hornets Discovered In US For First Time. They are all published within the past week or so but also quote a few people who encountered them last year... So this is actually old news that no one really cared about ~8 months ago. Then they usually play up how just how dangerous these Asian MURDER Hornets are, OMG!!! And there's this implication that they're going to be everywhere by the end of the year.
What's lacking though is anything current. Their hives are annual, growing to a great size by the autumn months and dying out completely from lack of food. It's only through a new generation of queens that survive the winter that they species survives each year. So if they are in the U.S. and Canada still, their hives currently aren't that big. And even if surveys don't come up with anything this year, no one can really say with confidence that they're not here until about 5 years of no sightings. They might be establishing someplace outside of where the surveys are taking place, they might not be doing that great here, they might be able to make it out of the traps being setup, lots of issues could be going on.
Articles from colleges and scientific outlets are adding damage control to the theme. The U.S. and Canada already several native Hornets, Yellow Jackets, European Hornets (which are a problem in themselves), Cicada Killers, and even Bumblebees that the general public is more than likely going to assume are Asian Murder Hornets thanks to sensationalist articles.
Again this is all because a total of ~4 hives were found in 2 locations. I actually couldn't find a good source on this because one article included someone finding all of their honeybees dead and just assumed it was them. There was no information given as to what destroyed this hive or even what condition it was in.
Assuming they are found and do establish, it will be quite a few years before they make it to the east coast. The new queens each year are only going to fly X amount of miles each year so their range is going to slowly expand unless they tuck themselves away in fire wood or something that's being transported, for example.
Some people have contacted me saying they're are worried about what they can do to help Beekeepers defend against them. Honestly we're not quite there yet. But their fear mostly comes from a clip from a National Geographic documentary that's often linked with these articles. It shows these hornets destroying a hive of Honeybees.
Well here's the thing with that; throughout Europe and Asia, there are Beekeepers. And there are hives of Honeybees that are bred to have a defense against these hornets. They actually ball up around the scout hornet marking their nest and cook it with heat generated from their wing muscles until it's dead. Alternatively a small strip of metal screen the hornets can't fit through stapled over the entrance also works. It's like a $5 fix. Somehow that didn't make it into the documentary though.
As for the threat of a hornet nest (Asian, European, or Native) posing a threat to people... there is a whole industry of exterminators and several well stocked shelves of pesticides at your local hardware, garden center, and in most grocery stores that can take care of that.
