This is my first hive started in spring
This is my first post to this wonderful forum
I have a screened bottom board and theses little bugs seem to be coming from inside the hive.
They are very small and move a lot faster than the varroa mites which are lager than this bug
Should I bee concerned.
My first thought was bee louse

Is it a small hive bettle?

EDIT... I just noticed you said the VMite was LARGER than this bug, so ignore my post.

This bug is much smaller than the SHB bug and it is not black
You have to look carefully to see these bugs on the board
The picture is magnified

At this time of year I am seeing quite a few woodlouse (roly-poly, pill bug, doodle bug...etc.) nymphs. They are especially attracted to dark damp locations, like you might have underneath the edges of a bottom board. Could you be seeing these, too? They are quick, dark grey in color and rather rapid for their size.
