If someone discovers a very aggressive hive, what should be done?

In the case of encountering a very aggressive hive, the best course of action is to call a professional for assistance. Aggressive bee behavior can indicate that the hive is under stress or that the bees are highly defensive, which can pose safety risks to inexperienced beekeepers. Professionals, such as experienced beekeepers or pest control experts, possess the necessary skills and tools to assess the situation safely and effectively. They can manage aggressive behavior properly, potentially identifying underlying issues, such as disease or a queen with aggressive traits, and work to mitigate those risks.

While attempting to calm the bees with smoke may help in some situations, it does not address the root causes of aggression and could worsen the situation if not done correctly. Moving the hive might not be advisable either, as this can provoke the bees further if not executed with understanding of their behavior. Monitoring from a distance may provide some safety, but it does not resolve the problem and leaves the aggressive hive without proper management or intervention. Therefore, reaching out to an experienced professional is the most sensible and safest approach.
