This has since been proven false by a number of people.
Jeff's assumption was the original assumption behind
the screened bottom board design that was to be placed
atop a solid bottom. "Open bottoms" have since been
introduced.
You can test this yourself with mites that fall onto a
"dry" board (rather than a sticky board) as follows:
a) Put the mites in a Tupperware container
b) Watch them climb out, even out of a container 4
inches or more in height.

But I do not think that the reason for the failure of
the "Dump-n-Brush" method can be said to be due to
climbing mites, as I tried it over and over with open
mesh bottoms.
