I just dealt with this too! It's horrible, isn't it?
Wet sheet all the way to the ground and an entrance reducer -- I closed mine up entirely -- while you run buy some wire window screen and a staplegun. Cut a strip to fit the entrance and staple it on to allow ventilation but keep your bees in and robbers out.
I also moved my suffering nucs. I moved them from the immediate vicinity to deploy my defenses then moved again to further confuse attackers.
Suggestions also made to me included the following:
Shut the offending hive if possible
Feed the offending hive if possible
Open all the hives, which puts them on the defensive side
Entrance reducers to allow one bee through at a time...I had this in place already, but if you don't, it's a great idea. You could even put on a reducer to allow no traffic.
Robbing screens will be placed on all new or small hives in my yard from now on.
After the emergency screen went on, the robbers climbed all over the nucs searching hard for a way end, but they gave up. I know the poor nucs have food and water, so I'm leaving them closed in with the screen for another day or two, then I'll put on robbing screens and open them back up.
Good luck!
