Glossary
A large-capacity syrup feeder shaped like a standard hive frame that sits inside the hive body, replacing one or two frames. Frame feeders (also called division board feeders) hold 1-3 gallons of sugar syrup and allow bees to access the syrup from inside the hive without exposure to robbing or drowning risks associated with external feeders.
Frame feeders are typically made of molded plastic in the dimensions of a standard deep frame. They insert into the hive like a regular frame, resting on the frame rests with capacity for 1-3 gallons of syrup depending on the model. Internal roughened surfaces or ladders allow bees to climb in and out without drowning.
The primary advantages are high capacity (more syrup between refills), internal placement (no robbing stimulus for other colonies), and protection from weather. They are the preferred feeder type for many commercial beekeepers who need efficient, high-volume feeding capabilities.
The main disadvantage is that refilling requires opening the hive, disturbing the colony each time. Bees can also drown in frame feeders if the internal climbing surfaces become slippery with syrup. Adding a handful of straw or small sticks provides additional flotation insurance.
Alternative feeder types include top feeders (sit on top of the hive, easy to refill without opening), entrance feeders (jars inverted at the entrance, easy to monitor but small capacity and prone to triggering robbing), and baggie feeders (zip-lock bags of syrup on top bars, inexpensive but single-use).
Depending on the model, 1 to 3 gallons. A standard deep frame feeder holds approximately 1 gallon. Larger models replacing two frames can hold 2-3 gallons. One gallon of 1:1 sugar syrup weighs approximately 10 pounds.
Drowning is a legitimate risk, especially with smooth-walled feeders. Choose feeders with textured climbing surfaces, and add straw or small sticks as flotation devices. Modern frame feeder designs have addressed this with improved interior textures and built-in ladders.
Frame feeders are best when you need high-capacity feeding and do not mind opening the hive to refill. Top feeders are better when you want to refill without disturbing the colony. Entrance feeders are best for monitoring consumption but have low capacity and can trigger robbing.
