Last year Clover queen bee initiated a thread "Apiguard and other thymol varroicides.." After a slow start the thread picked up but basically no one gave advice based on real experience on how to use thymol and how effective it was for controlling varroa. I'd like to make an attempt at gleaning information on any aspect of thymol treatment aginst varroa that the forum can supply: Where do you get it? (prepared?/self concocted?) What concentration do you use? How do you apply thymol? How often? Can it be used while the bees are storing honey for eventual extraction and sale? And, most importantly--Have you found it to be effective? And how did you assess its effectiveness. There are a lot of questions here and maybe you don't have answers for all of them. But, if we all get together, maybe, collectively, as a forum, we can get some real answers to the subject.
