Diatomaceous Earth - 1L
Diatomaceous Earth is zillions of microscopic glass skeletons of prehistoric sea creatures ground into a fine dust. Sold as an anti-caking additive for animal feed, but commonly used to deter arthropod pests e.g. mites, ticks, etc. Chemically inert but it's still best to take care not to inhale the dust, as it is essentially microscopic glass shards. Non-calcined, Feed Grade.
Packaged in a Re-useable Mason Jar.
