Try placing a large bucket of fresh water away from the pool and put a dish of Sprite next to it to draw them over there. They are looking for a source of water and sweat bees love, love, love Sprite! At least the bees on our last camping trip love Sprite! If you have any water features like a fountain run it while you are swimming, the splash may help keep bees away. Check the pH after running a water feature for a long time since the splashing will drive up pH over time.
