Re: Directing traffic...temporary
I would put a screen on the front so they can't get out for the day. I wouldn't put a cover over them as they might not get enough air through the sheet (I killed one queen that way once). I would seal it up after the sun goes down so all the girls are inside. I'd also take off the bottom so there is more ventilation. If only a box or two you might want to move it out of their way so they don't trip over it and knock it all over the place and have bees flying.
