This is a feeder that is placed in the entrance of your hive. Used for new packages and spring feeding. Simply take any glass mason jar, screw on the holed top, and place it in the entrance feeder. The liquid gravity feeds as the bees request it. Color of metal is subject to change. Fits 8 - or 10-frame hives. Can be used with some modifications with other types of hives. In fall, we suggest using this only as an inside feeder and not at the entrance.
