Was there more to the report (confirming these claims) that was not quoted
in the post?  There is no indication that the "mite drop" on either chemical
was dead or live mites (another reason to use a screened bottom board).
Nor, that the mite drop from the Apistan was not enough to control the mite
population   3,800 mites per day, after 42 days, even with decreasing
numbers each days, as the population decreases, should eliminate even a very
large population of mites.

The problem is that the mites that were dropped by the apistan were not =
killed.  Also the percent of the total mite population dropped by apistan =
was not high enough to give control of the varroa mites in these hives.
