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!).
