I lived in the Southwest when the africanized bees arrived, and there was indeed a sharp increase in attacks, a couple deaths over a a number of years, a lot of pets getting attacked. Then people just moved on and people learned to not fuck around with hives.

I don't know if it was the queens de-agressing in the new environment or public awareness or just media hype dying down, or all of the above, but yeah, it turned out to be the least of our actual worries in the 21st century.
