DiaSource® Diatomaceous Earth Crawling Insect Killer
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 around children 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 all animals with internal skeletons. This product is
recommended in the "IPM Guidelines for Schools in Texas" that reside on the EPA's
web site....

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 can effect
lung tissue and lead to the disease Silicosis. While all diatom skeletons are composed
of silica, DiaSource Diatomaceous Earth is composed of amorphous silica,
possessing undetectable levels of the harmful crystalline silica. 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 undetectable levels of less than 0.1% (one tenth of
one percent) 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.
