I replied Mite falls have settled down now and all colonies have recovered or are recovering. by concentrating on the beneficial effect of Apiguard, I might have given the impression that colony recovery was contrary to Bob's observation that there is a critical point past which they do not recover. I omitted to say I had to add brood and bees to some colonies to help them recover and 2 colonies never expanded normally (without additional frames). They have been united to this years' nucs. The little boost from the old bees helped the nucs to production level. One even had a queen and about 100 bees in the spring and given a couple of frames of emerging brood and young bees, kicked off, to profit later from another frame. She only just made it. As far as Apistan assisting the thymol, I do change comb in a 3 year cycle. All my wax has come from sources which predate the application of Apistan, so there will be a decreasing amount of Apistan in the wax. -- James Kilty :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
