SO sorry the elderly lady has to suffer this way. I guess those were africanized bees and not regular honeybees. With many hives dying out, there is usually some effort to move the bees to a less dangerous location.
Something like this terrifies me, because I was never tested to see if I’m allergic to stings.
No need to spray the bees and kill them.
Just capture as many as you can, put them in a hive and Re-Queen.
Have to wonder, since it’s written by a “journalist”, and they didn’t call in a bee keper. Was it actually bees; Africanised bees; or something else entirely that also builds “hives”, flies,and stings?
