Hi,
 
I claim almost 100% control of both tracheal and varroa mites by
placing one Trebor Extra Strong Mint on top every other brood frame.
 I assume that the effect is due to the high level of menthol
contained in Trebor Extra Strong Mints.
 
Also,  I have found a very rapid knockdown of varroa mites by adding
3 Eucalyptus 'Tunes' to my smoker.  On the packet of these very
effective throat pastilles I note that the ingredients include
Eucalyptus,  Menthol,  Camphor and HONEY!.
 
I am in the habit of smoking myself before working my bees and since
adding 'Tunes' to my smoker I have been completely free of both
headlice and influenza.  Food for thought?
