If the "bees" have no fuzz but instead look shiny, they are wasps, which are bee killers. I personally have no qualms killing wasps because they mutilated the quiet little honey bee hive on my property two years ago.
Thanks, White. Your info is great!
And Brysing, no, I don't know much about bees, other than the Africanized ones came to Arizona years ago. I got thanked for reporting them. They even killed a horse out here! And going into water doesn't help. They will wait. lol
MaidenCrow, I would leave it to the pros to fix your problem, unless you want to get stung. If they already have a hive, it needs moved or destroyed; moved being preferable.
