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.
The only time DE should be used is by a professional.The type of DE that can be bought by the general public does not have the killing compound in it.
Is DE safe?
Try to avoid using diatomaceous earth. DE is an inhalation hazard per the CDC. It can cause silicosis. You need to be protected from inhaling it when applied. 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 or on your furniture where a breeze or movement 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.
