A wooden Benton queen cage fits into the frame and she is released into a large screened area. The colony tends to her until they have accepted her and you are ready to release her. Open the door and let her walk out. If your Benton cage is a little loose in the frame, secure it with a little wax to make sure it doesn’t fall out.
Another use for this device is to control Verroa Mites. Catch your queen and put her into the large screen area with a wax stopper in the side hole. Leave the device in the hive in place of a regular frame for 5 days. Release the queen after the 5th day and she will be laying in full by the 7th day. This will break the brood cycle of the bees as well as the verroa mites and the mite population will drop drastically.
