Has anyone had any experience/success using oil extracts of
plants from the Family  Laminaceae as a substitute for using
Apistan strips?
 
Here in the states some people have been experimenting with
oils from Thyme, wintergreen, spearmint, and a few other oils
and oil combinations as an attempt to lessen the effects that
varroa have on the hives.
 
Any information on this would be very much appreciated.
 
Thank you
