The comb of a hive I purchased from a retired commercial beekeeper is noticeably darker (deep brown) than comb from a hive I purchased from a member of the bee club we belong to, which in turn is darker than newly-drawn comb.
Is there a "useful life" for comb, after which it should be removed and the bees allowed to draw new comb? If these combs are disease free, can they be used indefinitely?
I read that it takes around 9 pounds of honey to create one pound of comb, so reusing comb is highly desireable to the efficiency of a hive.
