What is DE?

Diatomaceous Earth is a naturally occurring siliceous sedimentary mineral compound from microscopic skeletal remains of unicellular algae-like plants called diatoms. These plants have been part of the earth’s ecology since prehistoric times.

Is DE safe?

Try to avoid using diatomaceous earth. DE is an inhalation hazard per the CDC. It can cause silicosis. You need to protect yourself from inhaling it and NIOSH recommends a filter depending on the concentration but go for a P100 filtered respirator. No dust is safe if inhaled. Do not use large quantities that are likely to be kicked up and inhaled, and do not place in windowsills where a breeze might blow the dust around. DE or any pesticide dust is for use only in areas where the living things present are ones you want to die. Cracks, crevices, wall voids etc, applied then left undisturbed. Apply it, wearing your PPE, Personal Protective Equipment, ventilate the place when done before removing your safety gear.
