Owners of food-grade DE like this tend to value the simple single-ingredient powder and the included duster. The common complaints are the dust it throws and confusion over what it is legally allowed to claim as an insect product.
This is 4 lbs of food grade diatomaceous earth (DE) made from 100% ground freshwater diatomaceous earth, with no additives or fillers. DE is made of the naturally occurring fossilized remains of diatoms, a type of algae that forms in freshwater. The remains are ground into a soft, fine white powder.
The powder is mined in Nevada and packaged in Georgia in an airtight 4 lb bag. A powder duster comes in the bag, so you can apply a fine dusting in hard-to-reach areas. The product is chemical free and OMRI Listed for organic use.
This powder is not approved by the EPA as an insect killer for roaches, bed bugs, ants, fleas, silverfish, scorpions or any other insect.
