Newbie here. I live in a hot interior valley of California. This weekend is forecasted to have temperatures potentially in excess of 110 degrees. Today was in the high 90's and the face of my hives are covered in bees, I assume they are trying to cool off. How can I help them cool off better and keep comfortable during these heat waves? We had several episodes of hive robbing recently so all entrances are down to minimum. Thanks for any advice you can give.
