i am working with a beekeeper who has a tracheal mite problem. He has lost
500 plus colonies.   He claims to have reduced his infestation by using
spirits of peppermint on a pad on the top of the frames.   Counts of adult
mite went from 74% of hive infested to 50% in 7 days.  This coming season he
was planning to using three treatments 5 days apart.   Does anyone have any
experience with this treatment or any comments?
 
Thanks for any suggestions
