    Re: VarroMed...something new coming

    Hi Clyde,

    I keep the varroa numbers down all year long, so usually I need only one treatment in Spring and that is it. But I do monitor all year round as well, and if I see varroa becoming a...

    Re: VarroMed...something new coming

    That trial was poorly designed from the very start. I don't understand how people still share this "experiment". What do you expect, if you wait until end of August, letting mite population grow way...

    Re: Running two queen colonies

    I use the Brother Adam hive, which has 12 Dadant frames. Divided by a divider board (bee tight) into two sections. Each section gets four combs of brood maximum. Never more than 4 frames Dadant,...
  10. Re: Queen Rearing with Michael Palmer method

    Not really.

    It is the standard method for professional beekeepers and with the use of entrance boards/landing boards down to the ground, the queens will crawl back up into the hive. Clip only one...

    Re: VarroMed...something new coming

    I use Varromed with great success since two years. It is easy and very effective.

    Because there is no sugar, the dribbling oxalic acid is less harmful than sugary oxalic acid solutions, because...
  12. Re: The use of 48hr queen cells to spread resistant genetics

    I would neither buy or sell such poorly developed 48 h-cells. :s Nor use them, since bad feeding doesn't produce good queens.

    That's how those cells look like after 48 h and proper feeding:

  13. Re: Quaring with Michael Palmer method

    The young queen stays about two or three weeks in the Apidea. Shortly after being mated she is removed, before that she lays eggs and the broodnest in the Apidea continues to live on.

    The last...
  14. Re: Quaring with Michael Palmer method

    I dequeen the Apideas and after 3 hours I introduce the virgin queen from the top. Or the next day. I simply drop them in and have 100 % success. I know, that some find that troublesome. If you dip...
  15. Re: Queen Rearing with Michael Palmer method

    This ladle is huge and yes, it is a bit more than a cup o bees. I introduce the old queen about three hours later. I wait until all combs are drawn and filled with capped brood. I do like to wait...
  16. Re: Queen Rearing with Michael Palmer method

    I run 500 of the Apidea mini foam nucs all year long. I don't winter them though. But I do use them to continually mate queens in them.

    I never start them queenless, means not with a cell, I start...

    Re: --Never Say 2019--

    The super is sitting at an 90° angle to the brood frames. Before adding another super on top, I rotate it 180°. So it sits again at an angle of 90° to the brood frames.

  25. Re: German Black bees in the Southeastern US actually Apis mellifera iberiensis?
