I finally bought a bag of DE because I've heard so much about it's magical powers. I thought it would look like dirt and boy was I surprised to find a white powdery substance. What I would like to know is, what all do you use DE for and how much to you use? I've heard adding it to the dustbath is good for mite control. Some people feed it to the birds? Someone said rub it into their perch? Sprinkle it in the nesting boxes? Rub it on the bird? What do you do with DE? I'm here to learn.....Can you use too much?
