A bit of a long story...
I've been doing a local festival for about the past five years. This festival has two events per year, a spring show and a fall show. The setting of the festival is right in the middle of a residential district (high density of homes with VERY tiny lots). Throughout the years that I've been doing the festival there has never been problems with local bees coming around bothering the festival participants. This past show was a very different story. I typically bring an OB hive and offer honey samples of a variety of local honeys. This year our tent was mobbed by local bees - probably about 50 - 70 bees at all times throughout the day. Of course, most people handled it pretty well, but there were several that were quite freaked out by the bees buzzing around. Of course the OB hive and even the slightest scent of honey brought them into my tent like crazy. Bees were even crawling on the honey sticks trying to get honey. Fortunately no one was stung at my tent, but it was a nerve wracking event. Unfortunately other were not as lucky. The snow cone guy was stung, and an artist a few tents down was also stung. Many people at the festival were blaming me for not containing the bees in my observation hive. Of course that totally false as my OB hive is completely secure and was not the source of the bees outside the hive.
Last Fall at this same show a guy from the local neighborhood leaned across the table and whispered "I've got a hive right over there..." pointing to the block adjacent to the park. He was clearly a newbee, and I said in reply that you need to manage them well come next spring so that your neighbors don't freak out at the first swarm. Well, that next spring the swarm came and our club was called in to retrieve the swam. The neighbors were not happy and tried to blame our club for the events that occurred. FYI, the owner of the hive is not a member of our club. Fast forward to this past weekend, these bees were very likely from the same guy. We never had problems with bees in prior years. Another piece of information is that the city in question has an ordinance restricting beekeeping unless the lot size is 5 acres.
Although being a strong supporter of keeping honeybees, the events of this past weekend enlightened me to the obvious perils of keeping bees in a highly populated urban setting. The festival coordinator was VERY upset with the situation. Trashcans were swarming with honeybees. Bees were landing on everything that seemed to be even a remote source of food. I do not know the total sting count, but there had to be many given the huge crowds and the number of bees flying around the park.
Seeking general comments.
