The Vivaldi Board has become a key tool in the Pacific Northwest in managing hive temperature and moisture.
Invented by John Edwards 15 years ago , the combination Vivaldi Board and Vivaldi Screen was developed to address the moisture problems of the North West. The screened vent slots provide ventilation in the hot months and mitigates moisture build-up. The Vivaldi Screen enables moisture to efficiently wick moisture into the Vivaldi board by increasing the surface area of absorption. We use burlap but you can also use sheep wool, cedar shavings or other natural material. You can also provide emergency winter feeding of Drivert sugar directly through the screen. We find that the bees love congregating under the Vivaldi Screen in winter because it is the warmest spot in the hive.
