Re: Penn State "COMB" project posts Dec 2019 update
It is almost funny to read threads like this one and see the interplay between different philosophies. JWC started the thread as a way to pooh-pooh treatment free methods. Posts then accumulate dissecting the methods used in the referenced study. JWC comes back complaining about lack of proof that TF works or can ever work. Claims beget counterclaims and in the end nobody learns anything new. Sometimes it is not worth the time expended reading and responding.
My experience with not treating bees is that sometimes it is better to treat. That said, I have not treated my bees in 15 years and they are clearly expressing mite resistance traits in some colonies. The trope about pesticides being a major problem for beekeepers and particularly that wax contaminated with pesticides causes issues is IMO the second largest threat beekeeping faces today.
