For anyone who has lived in the American South or Southwest in the last 20 years, I don't think there's anything new in this article. Pretty much everyone knew that yes, of course, "killer bees" doesn't mean they're terrorizing the countryside, but it does mean you have to be a lot more careful around them.
I remember hearing reports of people being stung to death because they accidentally knocked down a hive while working in the yard or mowed over a burrow. I think everyone, after the initial panic, just learned to recalibrate their behavior around hives and got accustomed to the "new normal".
