Robbing Screens On All The Time? Virgin Queen Return?

[greenbtree]

I had a lot of robbing last year, especially in the Fall, but on and off even before that.  I am expecting more early this Spring.  When you have a full time job, you don't always catch them in the act.  Does anyone leave robbing screens on their hives all the time?  Any down side to this?

 I've seen videos of people putting up plates in front of the entrances to help stop the robbing. They also cut back on the size of the entrance so the bees could better defend. As long as the bees can find their way in and out, it doesn't seem to bother them.

A slight slow down in traffic during a flow.

I have similar concerns, would mating queens find their way back in an always-on-screen scenario?  Thank you.

I didn't even think off the returning queen scenario.  Good question.
