The program to remove the bees was far more tactically rigorous: for five years, beginning in 1988, scientists carefully mapped all the colonies, killing off the easy ones. In 1994, they introduced a parasitic mite to take care of the rest. By 2002, only one colony was left, on top of a grade named Matzana. Within seven months, that was gone, too.
So they eridacate everything but introduce a parasitic mite only in America.
