I have to question whether this is how we should keeping bees. Think about it.
I have only treated with thymol since varroa was found here in 1997; the dose has been gradually reduced and many colonies will now only get one treatment this autumn. Yes, we have had moderately high winter losses - but sustainable, and now very rarely see any deformed wings. Colonies are doing well with yields well above the national average.
Best wishes
