The eco-conscious and budget-friendly choice! Millions of tons of industrial wood waste due to natural knots, blemishes, and holes enter our landfills each year. Instead of throwing these pieces of wood in the trash, we offer discounted farm grade trays that embrace these knots, marks, and spots. These imperfections do not impact nesting bees, but they do positively impact our (and the bees) environment!

Our farm grade wood trays are long-lasting, reusable, and easy to open for fall cocoon harvesting. Precision crafted of Pacific Northwest alder, our wood trays are a safe and natural nesting material for bees.
