Peter provided the below link to some interesting information. One thing
that got my attention was this:

"Bottom screens are also an effective control method. They are basically a
wood-bound screen that is placed underneath the brood chamber. The mites
fall through the screen onto the bottom board or ground."

What got my attention was that not so long ago there was some interesting
comments that the Bottom Screen wasn't effective enough to make a difference
in mite control. Now here is an article that shows it as an effective
control.

Peter was it you that did some study or reported some study that mentioned
that this type of control was basically didn't show enough control to be
useful?
