"I don't think they will have much trouble moving North."

I agree with Billy: Africanized bees will move as far North as a semi or a
pickup truck from any already-Africanized state in the US can travel.

As to how far North these bugs can successfully over-winter; well, that's
another story.  We should take our clues from how far South they have been
able to colonize in South America.
