Oh brother, I tried to zip loc baggie feeder last spring, it worked great!!! Except. My husband had built me a little mini super about 2 inches tall (does this have a name?). The bees loved the sugar and drank it all up, smile, but they at the same time built a whole bunch of comb from the inner cover down to the top of the frames, what a mess!!!! When I lifted off the inner cover, there were all the combs just a hangin' down!!!! :roll:Must have done something wrong with the design!!!! Have a wonderful day, greatest of this life. Cindi
