10 F Screened Bottom Board-BetterBee

Our beehive screened bottom board features an extra-wide 4-3/4" entrance board and plastic corrugated monitoring tray. A screened bottom board not only increases ventilation in your hive but also assists in monitoring varroa levels. To monitor for varroa mites, insert tray for 24 hours and then count the mite drop. Some run mite drops for 72 hours and divide the total by 3 for the daily number of mites.
