I agree with 2Sox. If you can make sugar dusting or no treatment work, then that's great, but sugar dusting is a VERY soft treatment. I made a really hard go at sugar dusting with one of my hives this year. I dusted them every single week without fail for almost the whole summer, and when I did a sugar roll a couple weeks ago to test their mite load, they were at almost 10%! I'm treating them with MAQS right now. I do have a hive that seems to be doing well with sugar dusting alone, but they were queenless at 2 different times this year, so they had 2 brood breaks, and the hive never got very big over the summer.
