It will depend on what type of pollen trap. For Ontario type, yes you will
see varroa since it is basically a screen bottom board with larger holes for
bees to go upward.
for other types (the one that fits in the front), you might find a few mites
but here only the mites on foragers and only a small percentage would fell
(most of the time mites are not the bee legs!).
