I would anticipate your observations since a difference between 90% and 95%
would lead to what you see. The 4x5 would definitely be more effective. I
do not need that level of control now as I am looking at another future
treatment because of local conditions and would not anticipate an issue
from mite buildup from now until late September or early October. Plus the
final broodless treatment in November ends up as the most important control.

Thank you for your detailed comments. They are very helpful. Glad your EFB
is under control. It has been deadly for some here in Maine.
