What is Diatomaceous Earth?
Diatomaceous Earth (DE) is the fossilized skeletal remains of microscopic one-celled plants called diatoms that lived in the
sea and in fresh water lakes approximately 30 million years ago. At the end of the diatom’s life cycle its microscopic shell
drifted to the lake or sea floor (Diatoms extract silicon dioxide (SiO2) from the water to form the skeleton or shell). Over
the eons, these shells built-up into deposits, some hundreds of meters thick.

How does it work?
DiaSource DE is a mechanical insecticide; it contains no poisons or toxins. As insects crawl through DE, the powdered
mineral adheres to the insect's waxy outer layer (the epicuticle). The tiny particles then absorb moisture through the
epicuticle. As a result, insects rapidly lose their body fluid lipids and die of dehydration. The rate of absorption is a function
of the surface area of the individual diatoms. With an average surface area of 69.05 m²/g DiaSource; DE is able to rabidly
dispatch even the larger household insect pests.

Is it safe for my family and pets?
Yes. The physical properties of DiaSource DE cause it to be deadly to all insects as a result of its ability to break down the
epicuticle, however, these same physical properties are harmless to warm-blooded organisms with internal skeletons.

Are all brands of DE the same?
No. Diatomaceous Earth is found throughout the world, but the qualities of the various deposits vary widely. The single
health issue associated with DE revolves around the crystalline silica content of the individual products. Silica in its
crystalline form possesses sharp point that can puncture lung tissue and lead to the disease Silicosis. While all diatom
skeletons are composed of silica, these skeletons in their natural form are composed of amorphous silica that lacks sharp
points necessary for the particles to lodge in the lungs. This, however, is not true of all DE deposits. Some products on the
market today contain enough crystalline silica to be labeled as hazardous substances by OSHA and subject to extensive
precautions during application and exposure.
DiaSource DE has been laboratory tested and documented to contain
less than 0.1% crystalline silica and carries the label of a non-hazardous substance.

Mechanical vs Chemical Insecticides
All pesticides rely on contact to be effective. Because the physical characteristics of DiaSource DE have no harmful effects
on people or pets, it can be applied without worry of contact. In contrast, chemical pesticides rely on the pests contact with
poison or toxic residues which have known adverse affects on all who contact it, including people and pets. Additionally,
these toxic chemical residues break down or decay over time. DiaSource DE does not. Re-application is only necessary if
the product is removed from the application area by weather or routine cleaning.
