How do you keep sweat bees away from your pool?

No. Beehives are often located near a water source.

Occasionally some worker bees will even be sent out to gather some water to bring back to the hive to help with the process of converting nectar to honey as well as to make wax.

Also, water sources usually have the most varieties of flowers around them to provide bees with pollen and nectar.

So, really, you'll more likely attract bees who have been sent to seek water.
