But for area bees, the real estate boom is just beginning. "Abandoned buildings attract bees," said Roy Beckford, the University of Florida agricultural and natural resources agent in Lee County, who said he had received "quite a few calls" about bees in empty properties.

"Bees anywhere in the world will make homes in any building that is not occupied," Mr. Beckford said. "They send scouts out, and find a place where they will not be disturbed. They're looking for a sheltered place to build colonies and make honey." Bees also live in occupied homes.
