Honeybee visiting peach flower |

The bees are looking for water to take back to their hives. When it is hot out,
bees are continuously hauling water back to the hives to keep it cool. And
consequently they drown because the pool is not shallow.
She can try putting out a shallow
depression in the landscape away from the pool and see if they will land there
instead. They would prefer to haul water from a place that has a very shallow
amount of water like the edge of a pond or stream.
This way they can land on solid
ground, take water and fly away. Once they find it, they may make lots of trips
to it for water and be regular visitors. There is a hive somewhere fairly close
by.
