Checked on my TBH tonight and found a dozen or so SHB on some empty comb I added from a failed hive. Sorted through about half the bars and could only find the SHB on the empty comb and none among the comb being actively worked. No sign of SHB larva. The old comb closest to the comb being worked had the most on it and the SHB there were surrounded by a dozen bees which were constantly balling onto them and harrasing them. Since these comb are "extra" and the bees aren't using them should I take them out for now?
