was the treatment for tracheal mites as widespread and aggressive back then as the treatment of varroa is today?
I never treated for tracheal and dont feel that they impacted our operation too much. It was a difficult diagnosis with no clearly effective treatment originally, though eventually many started using aromatics like menthol. I tried the same no treatment strategy with varroa and quickly found out that this was a whole different "breed of cat". We had entire apiaries completely wiped out. I assume tracheal mites still exist in our operation and around the country but then thats just an assumption.
