Sanford A. Moss advocates for the double screen, a versatile and economical tool in apiculture that facilitates a variety of hive management techniques. This simple wooden frame, equipped with two layers of wire mesh, allows air circulation and scent sharing while keeping distinct colonies or queens physically separated. By utilizing this device, beekeepers can successfully manage two-queen colonies, prevent swarming, and introduce new queens with a high rate of acceptance. It also provides thermal assistance to weaker hives, making it particularly effective for equalizing colony strength or overwintering small nuclei in cold climates. Ultimately, the author suggests that the utility and low cost of the double screen make it an essential asset for any efficient beekeeping operation.
