> Here we have a person who treated for mites in all the ways we've been told to treat. Formic was used according to instructions, although I think the author said maybe it wasn't quite warm enough. Repeated OAV was done late in the season when the colonies were supposedly broodless. According to what we are told, this should work.
Those that are successful in treating varroa have worked out a procedure to test the efficacy of their treatments. As with everything in beekeeping, varroa treatment cannot be simply prescriptive. Efficacy requires observation using follow-up mite counts or you have no idea what you are doing.
When we are trying to determine anything from a beekeeper's account that leaves out many parts of the story we will likely be wrong. We really have no idea about how the treatments were installed, the age of the product, the strength of the colony - the list goes on. All we can see from photos is a colony that was decimated by varroa, leaving us to conclude this was an animal husbandry issue.
Even with a new time-release formula of OA, which I'm hoping for, one would still need to check mite levels.
