The man was operating a backhoe in Encinitas, in San Diego County, when he was attacked by the bees late Wednesday morning.
Encinitas Deputy Fire Chief Scott Henry says the man ran about 200 yards to an outhouse in an attempt to escape. Henry says firefighters found the man inside in full cardiac arrest.
Firefighters began CPR and took the man to a hospital, where he was pronounced dead.
It wasn't immediately clear if the toxins from the bee stings caused the man to go into cardiac arrest. His name and an official cause of death have not been released.
