Why Is Diatomite a Good Pesticide?

As we have already mentioned, the use of diatomaceous earth has several advantages, but nothing beats its use as a pesticide. Due to the natural structure of diatoms and their silica coating, diatomaceous earth acts physically and by contact with a drying effect.

When a pest with a chitin exoskeleton (its waxy outer covering) comes in contact with diatomite, the microscopic silica in the product perforates and destroys the waxy covering of the pest, causing its dehydration and death by desiccation.

This mineral has a physical contact action, so it does not generate resistance in insects (Order it here).
