TUCSON, Ariz. (AP) — Two deadly bee attacks in the past week in the Tucson area likely are the result of a warm winter and recent monsoon rain, experts said Friday.

“Rain makes flowers makes bees,” said Dr. Steven Thoenes, owner of Beemaster Inc., a pest control company in Tucson. “There were no freezes last winter to knock them down. We’re seeing a lot of big colonies now, and the bees are big and nasty.”
