I’m sure we all remember the “Murder Hornet” media hype in 2020 and 2021. That never seemed to amount to anything. It seemed like the media was just jumping on a story they could scare people with to get more attention and make money. But why was it that the Asian giant hornets were never able to make it in America?
Edit: I have gotten a few great answers. The gist if it is:
1: There was a great “eradication” program.
2: They can only spread so fast, and it’s at a pace much slower than I expected.
3: They are only well suited to thrive in coastal mountain areas, which includes a large but relatively small section of the west coast. They never had the potential to take over the US.
