My apologies if this is available in the now easily searched archives (I
don't have easy internet access).  I was wondering how late in the year it
is advisable to requeen.  Two hives will undergo treatment with Apistan
beginning somewhere around the first week of September.  That puts strip
removal time around October 16-30.  My understanding is that one should not
have strips in the hive at the same time you are introducing a new queen.
Is the end of October too late to requeen in NE Ohio?  Would it be better to
wait till spring?  Any and all insights are welcome.
