My daughter asked me this because she knows I keep bees. I don't have an answer so I am posting the question.
Where she lives she is surrounded by agricultural land (mostly Avocodos) and most of the owners have hives and there are some very healthy feral hives also. Her new swimming pool has become the watering hole for many many bees - her hot tub constantly looks like a swarm is hanging over it.
Is there anything practical that she can do to keep the bees away?
