Michael B, near Albany, wonders about using comb from a hive that died and asks "Am I being anal by wanting them to be super clean? There is dark residue left over on the frames, and I am wondering just how picky the bees will be." Michael, the answer to your question is "yes". The bees almost certainly died due to an infestation of varroa mites, which are no longer on your empty combs. The new bees will clean up your comb without any difficulty! There is a reasonably active bee club in your area, that meets in Ballston Spa the third Monday of alternative months. I suggest you join, as discussion with other beekeepers can help a lot. You can also contact their President to be put on a mailing list. I work a short distance from Scotia and would be glad to help further. If you have any interest please email me privately.
