A moving/robbing screen is a great resource to have on hand when robbing starts in your apiary, or when you need to move or temporarily closeup a hive. Place this on the front of the hive. You can quickly close all the entrances until robbing has ceased. Then open one entrance at a time. Robber bees cannot find a way into the hive.
Great to use when moving a hive.
Available in traditional wooden option 10-frame or Nuc and the new plastic universal robbing screen that fits a 10-frame or 8-frame.
Moving Escape screen (10-frame only) allows you to close the hive where bees inside cannot leave the hive, but bees coming home to the hive can find their way into the hive.
