Diatomaceous earth - your thoughts
Okay, so this probably isn't the right Forum topic but I couldn't think where to put it.
I want to use Diatomaceous earth as an insecticide. The cat has had a bout of fleas and I think the chickens might have them too. Looking into it, I think I could use it as a slug and snail killer and use it for red mite in the coop too.
What kind of damage could it do?
