Cold frames okay

[yoderski]

When replacing the Plastic Pierco drone frames used for varroa control, can I put cold or nearly frozen frames in the hive and let the bees deal with it?  Or would that be too much of shock to them.  What do you all do.  With the 90+ temps we are having, it wouldn't take long for them to get to hive temp.   It makes a lot less mess that way than thawing it out and then putting it back.  I need to do that this Saturday, but it is too late for this time-- I have the frames out out of the freezer and they are thawing already

I wouldn't put frozen frames into the hive it could chill the brood thereby introducing Chillbrood or Chalkbrood.  I would continue to let it thaw fully before inserting into the hive.

When replacing the Plastic Pierco drone frames used for varroa control,

Dutshes recommend to wash drone comb with garden host. then shake combs and dry in air. Cut heads of cappings first.

Never put anything frozen in the brood nest of a hive.  Don't put it back until it has thawed to room temperature.
