Just curious, when you girls do the powdered sugar, do you just do the top super and let it fall on down to the bottom, or do you take the supers apart and do each super separately?? The reason I am asking is, last year I took all the supers apart and dusted them all separately, but boy or boy was that a lot of work for me.
This year I am just dusting the top super and letting it fall on down to the bottom. I hope it works just as good.
To answer your question. I only do powdered sugar dusting as a way to control the mites. It worked really good for me last year as I said above that I did all the supers individually. A cup of powdered sugar for each super. (oh yeah, I also cut out drone brood once in a while)
This year I am only doing the top super and shall see how it goes. I am monitoring the mite count every other week and so far it us under control. Cannot get rid of them, just keep the count down.
