strezzedhaus on "how much dte is too much?"

day 2:
if i can see the white of the dte, should i vacuum and start over?

how should i apply it, then? i think i put way too much around but i'm not sure :(

i did use a little powder gun for it, but it still comes out kind of heavy.

i put it everywhere, inside of the underside of the sofa, under the sofa, in its crevices, around the books, behind the one thing i have on the wall, under and around the washing machines, shelves, desk, shoes...

i've patted some areas and removed it already, knowing it was too much.
but how do i really know?
