Silica is commonly found in nature as a component of everything from sand and rocks to plants and humans. However, diatomaceous earth is a concentrated source of silica, which makes it unique.
Effective against slugs, beetles, worms, fleas, mites, and most any spider or insect, it is not much of a concern for larger creatures. Because the particles are so small, DE is safe to use around other wildlife, children, and pets.
When it comes to environmental friendliness, diatomaceous earth gives some piece of mind in that area, as it doesn’t negatively affect the soil or surrounding waterways when used over time. In fact, DE is a sustainable source of silicon dioxide, an essential ingredient needed for poultry development.
Added to a sandbox filled with dirt, it makes a good dust bath for chickens, and can keep bird lice and fleas away.
It is also a potent remedy for fleas in the house. After you find your first flea, liberally sprinkle DE on your carpet and other cloth surfaces, and allow to sit for a minimum of 12 hours before vacuuming.
