For spring, summer, and fall. Worried about your new package on a cold night? Or maybe you can't figure out where to place your pollen patty in the hive? Finally a feeding system that overcomes many of the challenges of feeding bees during late winter, spring, summer and fall. This time of the year, many beekeepers fail to keep enough food in the strategic placement within the hive for maximum brood build up. For example, when temperatures reach 50 or below in the spring, say on a cool spring night, the cluster is no longer able to eat from the entrance feeder. And with the recent studies we know that bees need protein (pollen) as much if not more than just sugar or sugar water. The Burns Bees Feed System places the food strategically over the brood nest area, keeping food where bees can always access it even on cold nights. What about summer dearth, that period between summer and fall nectar flows? Bees often suffer from a lack of nutrition in the summer and fall. The Burns Bees Feed System keeps both liquid and patties on the hive for maximum preparation for winter. The Burns Bees Feed System includes 2 mason jar FEED CAPS. Does not include mason jars. Use board in place of inner cover.
