    Default Mildew Inside Hive

    Hi All
    It's about 54 degrees during the day here in NC. I have 3 hives and in the process of checking them today I noticed 3 things:

    1) The pollen paddies from Daddant in each of the hives had started to mildew. Have only been in the hives about a month
    2) The inside of the top covers were mildewing as well. I believe moisture was collecting inside each hive.
    3) A few hive beetles had started laying in the pollen paddies. Some larvae had hatched.

    I tossed out the pollen paddies and replaced them with new paddies. How do I correct the moisture problem and what are your thoughts on the hive beetle larvae in the paddies?

    Thanks

    don't use the patties from Dadant. It is recommended to dry feed in your area...

    If you don't vent, then you might want to look at that. Just make sure the vent opening is small, so the bees don't have to worry about guarding the opening. We keep hive beetle traps in the hive until we no longer see any hive beetles.

    RAK I finally had a fairly warm day where I could get inside the hives. I took your advice and removed the Pollen Paddies. I then put in a piece of parchment paper and added some powdered sugar. I figured the powdered sugar would help draw out the moisture.

    Thanks for the insight......

    You are moving in the right direction, dry sugar will help absorb moisture. But, powdered sugar generally has cornstarch added to prevent clumping of the sugar. Cornstarch is not digestible by bees, so its not recommended to feed large amounts of powdered sugar. Ordinary granulated sugar is a better choice.

    I agree with the advice above to also provide some kind of top vent to allow moisture to escape. One option is simply a small shim under the lid.
