In examining my dark wooden pull-out boards 24 hourse after dusting with sugar (and having scraped off all of the accumulated sugar one hour after dusting yesterday), I was suprised to find many mites of lighter and lighter shades of tan including 2 tiny mites on one board that were snow white and looked like the mite babies I once saw in some video.

I would never have noticed these white mites on a white bottom board or on a board covered with powdered sugar.

Are white baby mites like this on the bottom board evidence of Varroa-Specific-Hygiene (VSH)?
