Once I found in a "cachureos" yard some aluminium boxes of computer power supplys that had holes of the right dimentions for the bees to enter (around 4 mm). For some one with not many hives that could be an unexpensive option for reducers if cut to the proper dimentions. -- Juanse Barros J. APIZUR S.A.
