I shall be doing some before and after mite fall measures - alas I lost many of my before samples in a fire. Subjectively it does work. Spring assessments will confirm how well. So far I am using Apiguard (approx 1/3 thymol in 2/3 gel) only when mite numbers warrant it. I am not too worried about high effectiveness, at the 90% level or better, as I am also looking for bees that bite varroa legs off. Where this has been selected for, it does improve to the 60% level or higher (Wallner, Lips, Dews). -- James Kilty :::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::: -- Visit www.honeybeeworld.com/BEE-L for rules, FAQ and other info --- ::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::::
