A woman has survived being stung at least 200 times by thousands of bees outside a home in California, according to United States fire authorities.

The woman in her 50s, known only as Maria, was reportedly the housekeeper and was going to get a mop out of her car at the home in Lake Forest, east of Los Angeles.

Orange County Fire Authority captain Tony Bommarito said rescuers had to grab a fire extinguisher to get rid of the Africanised honey bees, also known locally as "killer bees"

“The rescuers grabbed the first thing they could, which was a carbon dioxide extinguisher, sprayed the patient and tried to get as many bees as they could off her." he said.
