geez. I guess you don’t like to argue because you can’t support your position?
Diatomaceous Earth is almost pure silica (with some beneficial trace minerals); under a microscope, it looks like shards of glass (glass is made from silica). On any beetle-type insect that has a carapace, like fleas and cockroaches, the DE works under the shell and punctures the body, which then dehydrates and the insect dies. DE is totally nontoxic. There is no buildup of tolerance like there is to poisons because the method of killing is PHYSICAL, not chemical.

Don’t be a troll. I don’t need to support a position, it’s a fact, just look it up.
I won’t reply again.
