Our screened bottom board has been updated this year by our partner Humble Abodes! A separate bottom board or rims are no longer needed; this is a combination bottom board and screen. The optional plastic corrugated tray is supported by two rims built into the varroa screen. The screened bottom features an extra deep 4-3/4" landing 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. For more information on mite monitoring, check out our mite monitoring page. During cold periods, leave the tray installed to reduce drafts to the hive.
You will also need a solid bottom board to create clearance for the solid tray. You will not need a solid bottom board if using the optional flat corrugated tray.
