A local NY beekeeper named Ed Lord introduced us to the screened bottom board many years ago. At the time it seemed a little scary given the nature of our upstate NY winters but within 2 years we were convinced and had replaced all of our solid bottom boards and have never looked back. The improvement in brood rearing, overwintering and reduction in mite counts make this bottom board a perfect fit with our IPM system.
Whether you are concerned about adequate ventilation or just want to be able to better monitor your mite counts, this screened bottom board with optional observation tray is the way to go.
