    Default powdered sugar treatment

    I have read that it is not advisable to use the store bought powdered sugar for varroa treatment because it contains starch. I have a pretty heavyduty blender, but when using it to make powdered sugar from granulated sugar the blender really struggles and overheats. So what are you guys doing for powdered sugar treatments?

    I don't do this, so I don't really know the answer to your question. Only that there is a difference between Powdered Sugar and Confectioners or Confectionery Sugar. Maybe that is what you should be using.

    Interesting, the bag I have says Confectioners Powdered Sugar. It lists sugar and cornstarch as ingredients. For all I know it may be the cornstarch that makes it work. I haven't heard of any reason not to use it. I don't believe, as a treatment for varroa, that it is very effective.

    Cornstarch is hard for the bees to digest, but in warm weather and the bees are able to take a dump it causes no problems. When used alone I have found that it does not keep varroa from reaching the economic threshold. Used on a just hived swarm before they have brood helps rid the bees of the mites they brought with them.

    Hi, we have been using powdered sugar for 6 years now, without any problems. I use store bought cane powdered sugar. It has small amounts of cornstarch in it and it hasn't caused any problems.
    The most important thing about using PS to reduce your mite load is to do at at least once a week for a 3 week period. You need to capture the mites hatching with the bees. When we had really bad infestations, we would dust twice a week for 3 weeks. It's time consuming and intensive, but really worth it. It reduce our mite load to tolerable levels. We have not lost a hive to varroa.
    For the last 3 years we have been working on changing our of our foundation to natural cell and small cell and this year, our mite load has been very low to none. We have dusted our bees on our schedule (before and inbetween our honey flows) and seen such low counts that we have not dusted the following two weeks. We are using the dusting to obseve our mite counts, like using a jar, but we do the whole hive.
    Have a great day,

    How much powder sugar do you use per deep box?
    I am thinking about using 1/4 cup powder in a flour sifter with a screen on top of the deep box. Is this enough powder sugar? I intend to have a sliding board to check for mite drop. I think I need to avoid getting powder in the surplus super, how about the super you intend to leave them for the winter?
