Most people would run from a hive that has hundreds of bees all over the entrance. But if the weather is hot, like it has been here, chances are your bees are bearding and not getting ready to swarm. Bees will hang outside of the hive when the temperature inside gets too hot. But if they are hanging outside the hive, and you see a lot of activity, then they might swarm. If you’ve had your bees for some time, you’ll know the difference in the activity.
