With 100% Pure Food Grade Diatomaceous Earth, you can protect your home and garden without resorting to harsh chemicals. What sets diatomaceous earth apart is that it works by physical rather than chemical action. One of nature’s richest sources of silica, diatomaceous earth consists of the fossilized remains of hard shelled algae known as diatoms. These fossilized shells are both highly absorptive and mildly abrasive.
Ingredients: Diatomaceous earth (fossil shell powder).
Directions: Can be used in the garden by sprinkling on plants and mixing into the soil surrounding them.
