## Root Cause

Diatomaceous earth is a fine silica dust that, when inhaled, causes mechanical irritation and inflammation of the respiratory tract in both pets and humans, potentially leading to silicosis with chronic exposure.

## Dead Ends

- **** — Wet DE loses its abrasive properties and becomes ineffective against fleas; it must be dry to work, but dry application creates airborne dust. (60% fail)
- **** — DE particles can become airborne when the pet moves or when bedding is disturbed, leading to inhalation by both pet and owner. (50% fail)
- **** — Pets cannot wear masks; they will inhale the dust directly, especially if they sniff the area. (70% fail)
