Golder Ranch Fire Battalion Chief Will Seeley says the man was still hospitalized Friday with life-threatening injuries.
He was attacked Wednesday by a hive located in a shed.
The man's neighbor rushed to help him before firefighters and police arrived.
According to authorities, police tried to use fire extinguishers to get the bees away from the man before firefighters got him into their truck.
The man was transported to the hospital. Doctors say he sustained close to twice the lethal dose of bee venom.
Neighbors say they had noticed an unusual amount of bees earlier that day.
The hive has since been removed.
