As far as I am aware, there is no wonder drug around the corner to replace
Apistan [or Checkmite in The States]. Varroa resistance is serious trouble
and will only be restrained (not eliminated) by IPM practices being
introduced in treating our colonies.

I believe Max & I are on the same page.

I only wish to make the list aware of the limitations of the chemicals which
will be available now that we are moving into a new era of control of varroa
by chemicals which *are* temp and humidity effected. All the acids and
thymol and  fall into the class.

Monitoring is crucial to the success of IPM and good hive management.

Always has been but many (as Allen pointed out) are slow to learn.

In the USA, where beekeepers are now seeing resistance to pyrethroids, to
coumaphos and to amitraz, this is not going to disappear overnight; it will
gradually grow and spread unless other methods are used.

Allready is!

Max said:
Thymol-based treatments such as Apiguard, organic acid treatments or
biomechanical methods may not be everyone's preference but they may be more
helpful than you think, whether the mites in your colonies are
pesticide-resistant or not.
I guess it's a matter of individual choice.

Always has been. Beekeepers choose wisely! Be as knowledgeable as possible
on the treatment of choice.
