Can this help:

Thanks but it did not answer my question about persistence- how long it
keeps killing after treatment. Knowing that would lead to a proper interval
for vapor treatments. You can find intervals of four to 7 days which led to
my question.
BTW, my less than rigorous test using one untreated hive and one treatment
with vapor about a month before on three hives led to about half the number
of Varroa for the treated hives compared to the untreated.
