After observing this trapout, I would orient the trapout cone horizontally on all future projects. When there are large numbers of bees exiting the existing hive through the cone, they don't seem to have any problem. But when there are just one or two, it takes a while for the bees to stumble out of the bottom of the cone. They seem to search for the way out, get close to the bottom of the cone, then climb back up and do it over and over, and then after 10 minutes or so, they "trip" and stumble out and seem to wonder what happened. If this is any indication of what future trapouts would be like, I would go horizontal.
