Protect Your Beehive Monitoring for varroa is essential for protecting your honey bees! This varroa screen base allows varroa and debris to fall through the bottom of your hive. Use with a debris board (sold separately). Handcrafted by an Amish family who raises their own bees. Includes screen base only (debris board sold separately). Fits our 5-frame bee hives and components. Arrives fully assembled. Made of unpainted pine. Dimensions: 9-1/4"L x 22"W x 2-7/8"H. USA made in Ohio. Note: Debris board (the board that goes in the screen) is not included. FOR BEST CARE: We recommend any wooden hive component surface exposed to the elements be protected with exterior primer and paint before use. Only prime and paint the outside, not the inside where the bees live.
