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).
