It's hard to enjoy your endless Summer if bee stings come hand in hand with taking a dip in your pool. But bees have many uses for water, including drinking and using as material to build hives. So, unless there's another source of water nearby, you can bet your bottom dollar that they'll be making a poolside visit. According to the USDA, bees will forage any open water source, so the only way to detract them is by making the water unpalatable. You can do so by filling a spray bottle with a mix of 1/4 cup of dish soap or vinegar and a quart of water, and spraying bees that are at your pool. This will eliminate bees as they forage on water, and prevent others in the colony from learning about your pool's location.
