I receintly talked to a commercial bee keeper about mite control and she suggested that I drop several Halls Mentho-lyptus cough drops into the top of the hive as a preventive measure. The bees lick the drops and the vapours effect the mites. For those who are not familiar with the drops these are the active ingredients ; Menthol (8%- 15% depending on flavour) , Eucalyptus oil 7.2% Has anyone tried this method, and is it effective?
