Have they all been "Africanized"?
Funny you should say that. About three years ago, I was walking up to a house, that had a bunch of bees on one corner of it. I knocked on the door, and waited. After the second knock, a bee landed on me, then another, and then another, and another . . . . Decided it was time to leave. The bees followed me to the car, all the while stinging. They started to swarm around the car. and I left. We put an alert on the house, but in the next day or two, they were gone. They could have been just protecting the queen, but we think they were the Africanized ones. Getting more and more reports of such. Back when all those "Killer Bee" movies came out in the '80s, I remember reading that the US would be overrun by 2000.
