I've been using a bottom board for a couple of weeks and strugling to see the mites. I got some other bugs which im pretty sure are another harmless louse. Im not sure about the dead ones on the picture, are those mites?

There should be mites as we got them around, didnt see any and i've been checking my bottom board 3 times. Im in northern Europe.

Its my second year
