Feeding bees sugar syrup is essential to the rapid growth of a strong and productive colony. The HiveTopper feeder is a bee-commerce exclusive, designed and built to our specifications. Its quality one-piece seamless construction is fabricated from rugged plastic (like the bumpers on your automobile). Durable, food-safe, weatherproof, UV resistant, and 100% leak-proof. Bees feed on syrup via a rust-proof screened access. The screening is attached with rust-proof screws and can be removed for easy cleaning. With the screen removed, feeders can be nested and stacked for easy storage. Our unique design allows you to refill the feeder without ever disturbing your bees and with no risk of getting stung. Holds a whopping 3 gallons of liquid. You can even use it as a water source for your bees throughout the season. We use them (empty) on the hive throughout the winter, as the HiveTopper greatly improves ventilation in the hive and thus controls the build-up of dangerous condensation. These magnificent feeders from Bee-Commerce will last you for many years to come. Get one for each colony. Please feel free to download the instruction sheet for the Hive Topper.
