Honey Bee Mason Jar Ladder Feeder

Feeders are expensive and since jars are easy to come by why not reuse.  To keep bees from drowning they use the ladder with no issues and can take down syrup very quickly.  I set the jars directly on the frame bars and surround with an empty box spring through fall.
