Was that the outdoor pool?
We spent Labor Day Weekend at All Star Sports a few years ago.
Our son had his mug of soda at the pool with the lid on but in the open position where a straw would go, a bee got in. He got stung as he took a drink.
Nasty, nasty!
Bees were an issue last week at several of the pools we visited - especially at the Paddock pool at SSR. They gravitate to the beverage stations, but they were all over the pool area. Pretty typical for August, IMO. Less flowers blooming than spring & early summer, so bees look for other "food" sources.
