A 95-year-old Redondo Beach man attacked by bees Wednesday afternoon was stung up to 600 times.
The man was treated at a hospital and released.
Authorities said they could not confirm whether the bees are Africanized bees, but said it is likely.
The bees were agitated by a fumigator that was trying to exterminate the hive in an apartment roof nearby, police said. The man was walking in the 1700 block of Ruxton Lane when he was attacked.
Firefighters responding to the scene also were attacked by the bees, but because they were wearing protective gear, the firefighters were not stung.
The Los Angeles Vector Control set up warning signs and cordoned off the area. No one was evacuated.
