When something or someone ventures close to the treasured, honey-filled hive, bee sting attacks become a much more likely event. Watch for bees flying in and out of hidden places such as cracks in walls, hollows of trees, and shrubs. Be very careful of a possible nest in the ground that could be disturbed by inadvertently stepping on it or running a lawnmower over it. If there is bee activity, there is likely a nest.
