MITE TREATMENTS

This week I have been applying FormicPro to my hives.  The air temperatures have been within the recommended range of between 60 and 85F.  Hives have reacted differently to the treatments.  Here are pictures of 3 hives that are within 20 feet of each other.  We can all speculate on the reasons for the different reactions.

 This hive shows no reaction to the treatment. 

 This hive had slight bearding at the main entrance and vent hole.

This final hive has heavy bearding on the front and sides.  The bees are about 1 inch in thickness.
NOTE: The next morning all bees were inside again.
