I've been using it for years and have no issues, I put it in my animals food and dust then down with De,and no fleas, tix, mites, and no worms, sorry it didn't work for you, but it works for me and thousands of other people
Diatomaceous earth, (De) actually rids the body of roundworms, whipworms, pinworms, and hookworms within 7 days of being fed daily. But to be most effective, food grade diatomaceous earth must be fed long enough to catch all newly hatching eggs or cycling of the worms through the lungs and back...
Yes it's not a wormer but it works, There's 2 types of it, the food grade diatomaceous earth been used for many many years, it's used in restaurants as a thickening agent so it's definitely not asbestos, the other type of diatomaceous earth yes I agree with you but food grade is perfectly safe
