The regenerating cobwebs sound like quite a trial. I've got a few spiders sharing quarters with me. Wonder if they would be a good candidate for diatomaceous earth?   I really don't mind the Daddy Longlegs ones, but the small black ones are a bit unnerving. Not enough to spray poison, so far.

And dust is an ongoing enemy. I even found a thick layer of dust atop the dishwasher when it was pulled out from the wall Yikes, it gets in the strangest places. I used to have a great damp dustmop, it had a flat surface maybe the size of 8.5 x 11 paper, you would cover it with damp terrycloth with elastic binding, I think I had 3 of those, and could throw them in the washer.   It went away in the great garage sale of 2017.   

Seems like it would be great to have one here for floors, but I'll be darned if I can imagine what the keywords would be to find one online. I do have a rickety plastic swiffer-ish one I can secure damp microfiber cloths onto, but something sturdier is needed.

I'd rather be digging through flats of minerals, splitting the choice bits into small chunks and making micromounts or thumbnail mounts. Or playing music.
