Diatomaceous Earth is good stuff, but it is dusty and bad to breath. In the air it was what is considered the musty old home smell. I have used in in around walls, attics, under homes ect. I really like it as a non-chemical insect control, but I don't like to live or sleep in the type of powdery dust this stuff has.
