We have these little insects in our house, they look brown and round to the naked eye, they seem to be somewhat attracted to light since we found a cluster of ~6 on the wall next to a light, otherwise we find them one here and one there.

They are very very small, can barely tell what shape they are without magnification, they look almost like a dot.

Images below are taken with a loupe with 30x and 60x magnification but they are of squashed bugs so not the greatest photos, sorry. Will post pictures of live ones if I find more.
