I emailed Jean Paul Gaultier to ask if their cosmetics are vegan, and found out that bees are not animals and that they're appropriate for vegetarians.
According to a quick Google search, it's absolutely common practice by beekeepers specifically to prevent queens leaving. Check the beekeeping tab on this wiki page.
My point was never that they just leave, my point was that they don't need to leave and aren't supposed to, but besides that they live completely natural. And they still can leave when they feel like its better for the hive, the other methods don't physically hinder them to do that, they just don't need to do it, the only thing they can't do natural is changing the hive, wich in nature they do to prevent pests from accumulating, but thats the beekeepers job for honeybees.
