Honey bees are not aggressive.However, they are defensive and will attack only when it is defending it’s colony.
When honey bees swarm they first move to a temporary site such as a tree branch. The swarm will usually remain here for about 24-48 hours until a permanent location is found such as a bee hive, hollow tree, hollow wall, or an attic. Generally it is a place that is protected from the weather.
Bees in a swarm are very calm and not likely to sting. Honey bees encountered away from the hive are unlikely to sting unless provoked. However, if the hive entrance is approached, the guard bees can become very aggressive. Worker bees have barbed stingers. The stinger has a poison sac, and is ripped off the body of the stinging bee. In addition, the stinger gives off a pheromone which attracts other bees and creates an alarm for an attack. Therefore, immediate removal of the stinger is very important.
