Our Diatomaceous Earth (DE) also known as Organic Fossil Shell Flour

How does it work

Diatomaceous Earth mode of action is physical. The sharp, microscopic particles of DE, scrape away the outer covering of their exoskeletons, which normally functions to retain moisture. As a result, the affected pests gradually dry out and die from dehydration.

Its worth noting DE does not not harm certain insects like earthworms. As long as the DE is only sprinkled on top of the soil to allow worms to slowly digest it and work it in.

Where Can Diatomaceous earth be used

Our Diatomaceous Earth is amorphous, not crystalline. However as it comes in powder form. Always use a dust mask and gloves when applying.
