Got our bag O" Diatomaceous Earth-- Had trouble finding it since around Here they call it Fossil-Shell flour...easier to spell, AND say! LOL! Anyway--- the 1st thing the Lady says to me is "Make darned sure you don't breath-in the dust when you use it-- it can cause lung troubles!" ??????????????!!!!!!!!!! What??? When we spread it, AND when the chickens scratch, roll etc-- the dust flies EVERYWHERE-- and my Daughter sleeps in the same room! Didn't realize the extent of the dust problem until this morning-- we washed all the surfaces in her room before bed last night to remove the dust-- and by this morning, the dust is thick enough to write your name in it with your finger! Is this as hazardous as the woman said? Is this harming my kid??? What about the birds breathing it???? Anyone heard anything about this???? HELP!! Worried Momma!!!
