I didn't see any coming or going from under the lid. All of the bees that I saw were in the feeder box though, I didn't see a big pile in front of the entrance. We occasionally will see ants, beetles, or roaches coming/going under the lid to the feeder. I took off the feeder, super, queen screen, and blocked all except a 2 bee entrance (they had stuck the entrance guard down really good in the medium setting, so I put a piece of wood in to block most of the entrance that was left. But they were angry today! Usually they are so chill, but yesterday and today they were angry and defensive.
