I wouldn't think so. Diatomaceous earth is fossilized hard-shelled microalgae. Basically it's a very fine silica. Think microscopic razor blades. The way it kills bugs is by cutting through their exoskeletons. Once the exoskeletons are breached they dry out inside. That's a much different process than activated charcoal which absorbs moisture around it, including the water soluble nutrients and vitamins the moisture contains.
