> 3 dayI’m apparently really oblivious because when I bought this I didn’t realize it came with a nifty little tool to spritz the diatomaceous earth around with, but it works really well and the addition of it is much appreciated! I’m using this as a sort of barrier to keep potential (ear) mites from going into my bunny area while I treat them with Revolution so it’s gonna be hard to say if this specifically does anything to help but, I don’t doubt the efficacy.

> 3 dayThere was no powder duster included in the bag. While Im sure the product will function as intended, Im disappointed. Its difficult to dispense without the puffer.

> 3 dayI was excited to give this a whirl. Had read about D.E. for a while and decided to do it. This product is awesome. The duster that comes with it is quite large. Larger than I had envisioned, I suppose. Every spring I battle ants in my kitchen and bathroom directly above it. I dusted the cracks and where I knew they went and within 12 hours I noticed none, where I had 30 to 40 before. Did not last forever. After about a month I noticed a few scouts in both places today and will redust...perhaps monthly in summer. Good quality, nice duster, fast delivery.

> 3 dayI put this around the perimeter of my home inside and out! I haven’t seen any crawling bugs in a LONG TIME! I am getting ready to move to a new location and I’ll definitely be using this product to get rid of AND prevent any unwanted critters from entering my home.

> 3 dayWas able to use garden duster by sealing the crack with my finger. Have since glued it with a flexible clear adhesive. Will have to see if duster works now. Dusted a few fire ant mounds, and after more than 48 hours, they still are popping out when the mound is disturbed. Will try to greatly disturb the mound and dust the swarm, that way they drag it back in with them and hopefully contaminate others.

Harris Food Grade Diatomaceous Earth (DE) is composed of 100% ground freshwater DE, with no additives. The product is made of the naturally occuring fossilized remains of diatoms, a type of algae that forms in freshwater. These remains are ground up into a soft, fine white powder that carry 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 mined in Nevada and packaged in Georgia in a 4lb airtight bag. Included in the bag is a powder duster, allowing 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.
Powder Duster Included
Use the Harris powder duster with extension nozzle for application of food grade diatomaceous earth. Once filled, screw the cap on tight and turn the duster upside down. Keep powder as dry as possible, as it will clump and not puff properly if wet. Also, be careful not to fill the duster to much when first starting out to prevent clogging.

About PF Harris
Our Story
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.
