Re: Fluvalinate in wax
[QUOTE=Barry;1086755] – a good reason to rotate your comb, as some of the best beekeepers do. There should be a ppm (or ppb) level for fluvalinate (and maybe there is) above which the comb should be discarded. Same for coumaphos. [QUOTE]
Who are these best beekeepers? How much comb is the right amount to rotate out and when? Do these best beekeepers shake their bees onto new foundation and discard the old comb from a certain number of hives? What I have read, unless I misunderstand something, is that if one simply replaced two combs in each ten frame box each year w/ frames of foundation not only would it take 5 years to get all new comb in each box (as if anyone is that annally organized) but that somehow, over time, that new comb takes up properties of the old comb next to it in the box. So what have you accomplished?
And Coumaphos? I haven't used that stuff for over 15 years and it showed up in pollen samples in my beehives two years ago. I have heard the same from other beekeepers too. The suspicion is that bees are bringing it in from the environment. So how do you know when to rotate out combs because of coumaphos?
If one does do comb replacement rotation, shouldn't those combs be burned or sent to the landfill? Otherwise, won't the raw beeswax used for all sorts of things besides honeycomb foundation become more and more contaminated thus making replacement rotation a waste of time and resources?
Just because something is new to you, doesn't mean it is new, or revolutionary. Mark Berninghausen
