Riverrat,
I have learned from painful experience, as well as more than a few “I told you so” advisors that we are still far enough south that the majority of our feral bees have Africanized genetics. It is not as bad as Arizona is supposed to be, but bad enough that we are better off getting a queen from elsewhere.
They can start off calm and suddenly turn mean. If you wait too long to requeen, it can be really difficult to get a her accepted. Some people down here will work Africanized bees, but none of them keep them in their backyard.
