Harris Food Grade Diatomaceous Earth (DE) is composed of 100% ground freshwater DE, with no additives. The product is made of the naturally occurring fossilized remains of diatoms, a type of algae that forms in freshwater. These remains are ground up into a soft, fine white powder that carries many different uses. It's chemical free and completely safe to use around children and pets. 

Harris Diatomaceous Earth is listed with the Organic Minerals Research Institute (OMRI) for organic use. It's packaged in a 1/2 lb puffer bottle that allows for easy application of a fine dusting of powder. 

For every ten dollars in profit we receive for Diatomaceous Earth Food Grade, we have pledged to donate $1 to the Etowah Valley Humane Society (EVHS), a private non-profit organization that saves thousands of animals every year. Based in Cartersville, GA a short drive from the PF Harris manufacturing plant, EVHS aims to prevent cruelty, relieve suffering, and provide humane treatment for all animals in need. The organization actively works to eliminate root causes of suffering and acts as an educational resource for the community, with the main goal being to find a great home for animals in its custody. Below are a few of the impressive stats showing the impact EVHS has had on local animal lives in recent years:

• Rescued over 13,000 lives from Bartow County Animal Control since 2010
• Helped increase the number of live animals pulls from Bartow County Animal Control from 69/month to 207/month - a 300% increase
• Assisted in decreasing the Bartow County euthanasia rate six years in a row

Harris’ own Chief Financial Officer, Ed Brush, has been involved with the society for years. Seeing an opportunity to help a local organization doing so much good, PF Harris partnered with EVHS in an effort to combat animal cruelty and find deserving pets a loving home. We hope you will find value in our Food Grade Diatomaceous Earth while knowing that 10% of profits are going toward saving the lives of pets in Bartow County, Georgia.

Problem solving has a long heritage at PF Harris. In 1924, two years after its founding, the company tackled the Calvin Coolidge White House, which had been overrun for years by roaches and water bugs. Harris’s product was so successful in eliminating the scourge that he was described on the front page of the Washington Times as a "vermin slayer" who has just fought a decisive, winning battle with a horde of cockroaches which infested the lower regions of the Executive Mansion.

Over the course of the next few months Harris took “his final feast” to dozens of government buildings, including the Senate Office Building, the Department of Justice, the Supreme Court and Walter Reed Hospital. Success followed success: Each superintendent of the various buildings was highly satisfied with the results.

The company today stays nimble enough to respond to changing market demands, leading the way in the development of numerous products, including natural insect repellents like Swamp Gator and Swamp Gnat which repel biting insects without using deet. Beyond the products it sells, Harris helps customers find easy and economical solutions to pest problems through helpful labeling, instructive videos and personal advice.

It’s a brand with a reliable past and an innovative future. PF Harris is America’s oldest EPA-registered company. With more than 55 products, the company provides solutions to treat everything from roaches and bed bugs to scorpions and stink bugs.
