48-Hole Mason Bee Reusable Nesting Tray

  The perfect choice for annual mason bee raisers! Wood trays are long-lasting, reusable, and easy to open for fall cocoon harvesting. Precision crafted of Pacific Northwest alder, these wood trays are a safe and natural nesting material for bees. Wood material provides both insulation and moisture control to protect mason bee cocoons from extreme temperatures and mold caused by excess moisture. Wood is a porous material, which captures and retains natural nesting scents and helps to attract next season's bees. Reusable wood trays minimize year-to-year costs. The front of the trays are lightly burned, creating a visual pattern that helps female mason bees locate their nests and removes splinters that can harm bee’s wings. Side notches lock into neighboring trays, retain alignment, and help block pests from entering the nest from the side. All wood trays come with removable cardboard backing and pest-blocker fabric to prevent pests and parasites from entering the nest from the back.
