    Im SOOOOO EXCITED about this! I have been using it for 9 months in my artwork. Then it felt as if something, maybe God, kept bringing it to mind. After hearing about it about 4 more times I dug in to research it. I started taking it immediately and gave it to my dogs. Both of my dogs are 15 and they both almost died about 2-3 months ago at different times. My pain in my wrists and hands went from a 9 to a 3 in 4-5 days, Ill take it daily. My dog Sabian had the death look in her eyes and everyone told me to prepare my heart. When my dog Oscra almost died instead I was in shock. I hadnt prepared my heart for that. When I found the all the info on the diatomaceous earth I was hopeful. It worked so fast! My dogs, one of which could never climb one step, is now running and jumping up the 2 steps coming into my house. Within 2 days I noticed how much energy I had. I kept getting compliments on my hair and skin looking so good. Day 4 I got soooo much relief in my joints. My joint pain went from a 9 to a 3! I bought 60 lbs to give away! I gave away my 1 st 4 lb bag within the first week so Im hopeful that we are all on our way to healing. My body is detoxing but at a tolerable rate. It is easy to do life with this. It may change after Ive been on it a bit longer. This is week one. Ive never had anything Ive ever tried work this fast. Just dont breathe it or let your animals breathe it. It you or your animals are sick, sprinkle castor oil in their kibble then the diatomaceous earth, mix it up so they cant breathe it. For people, just put a teaspoon in tea or coffee 3 times a week. The castor oil does a seek and destroy mission on any viral infections. So if you try it...youll know really fast if it works. My pain went from a 9 to a 6 in my back from the castor oil. Then I fell down a flight of stairs. I use about 1/4-1/2 tsp of castor oil to the same amount D.E. for my 10 pound dogs. I dont measure, I just guesstimate it. My dogs like it and they have gotten so much better than Ive ever seen them. Bless you in your process. This is an amazing product! Wow!

    I use this for the vegetable garden and to discourage household pests. A little goes a long way and it is a readonably safe and effective natural bug deterrent. I put it under the built-in heaters, around where pipes go through the wall, on outer sills of windows that are close to ground level, under the fridge, under the stove, etc. to discourage insects and it is very helpful. I do not use the duster indoors as diatomaceous earth dust is dangerous to breathe or to get in your eyes. Always wear a safety mask and safety goggles when using it, make sure no kids or pets or anyone else is around, clean up after yourself to remove extraneous dust, and only apply it where kids and pets will not get at it. This is food grade and completely safe to ingest for people and animals - many people eat it as a health supplement and it is commonly fed to livestock - but breathing it in or getting it in your eyes is a no no as the particles in the dust are sharp. I have seen it applied carelessly with no ill effects to anyone, but better safe than sorry. This particular brand has a good reputation and 4 lbs. is perfect for my needs.

    We had a major ant problem in and around our house and I sprayed this powder around the edges on the outside of the house and behind cabinets and along baseboards etc inside in order to help repel and kill the ants. We had such a large ghost ant population around here, that I had to use various efforts to discourage them from coming in the house. I used this and boric acid at the same time because I just wanted to make sure that something would work. I also sprayed all around the house and put ant stakes inside and outside. But I know this works, because there have been times that I used it with nothing else. The problem with all these anti-ant substances or methods is that what often happens is THE ANTS DIE IN TRANSIT. So I began to find dead ants here and there and everywhere. They often die before they get back to their nest, and in fact they die sometimes on their way into the house after crossing over the path of the boric acid or diatomaceous earth or poison. So Ive been finding dead ants here and there around my house for over a month now, and I keep hoping they will leave me alone, but they seem intent on wanting to live in and around my house even though I dont leave out food or anything. By the way I was told these are called ghost ants. They seem to be everywhere in the area of Central Florida I was living in. One warning is to be very careful not to breathe diatomaceous earth. It can actually cause damage to your lungs if you breathe too much of it. I see many people using it carelessly. Be careful! For example when you open the bag, the powder begins to sift into the air immediately which reaches your lungs, so I advise wearing a good mask such as an n95 when messing with this stuff. It is almost impossible to use it in any way without it getting into your air space. So you have to be careful. People seem to think because you can actually mix this with water and drink it if it is the right type, that it is not dangerous. No it is not dangerous to drink it in water, but it is dangerous to breathe it in its normal dry form. I also use this as a gnat killer by spraying it on top of the soil of my potted plants. This seems to be working well. Diatomaceous earth has many uses, so I recommend you read about it, but use it responsibly. I gave it only four stars, because the sprayer that they give you with it doesnt really work very well. At times it doesnt spray out at all and other times it sprays too much. It is very difficult to control the sprayer. Ive seen other sprayers of this type that work better.

    This stuff works! I live in an older house. Its full of spiders. Mostly brown recluse. Ive tried everything to get rid of them aside from calling an exterminator. I wanted something safe to use because I have a cat. So I tried DE. I havent seen any spiders since I put it down. Earwigs seem to be an issue this year. DE dont kill them but they dont like it. Also the ant invasion on my back porch is almost gone. No beetles, no stink bugs, no snails sliming up my front door! Im telling you bugs wont cross it. Dont be too heavy applying it inside the house. A light dusting is enough. Otherwise you will have a mess thats hard to clean up. Outside will have to be reapplied after it rains.

    Great product! Use it in the garden and make my own supplements with a capsule filler and a little bit of citric acid. The 4lb bag at this price gives me plenty for both. The applicator/blower is garbage. Upside down does just a little bit more than nothing. Outlets on the bottom will blow 90% of it out in the first two puffs and leave you with a stopped up mess, and after just a few tries the sides of the bellow are starting to wrinkle and bind. I ended up using an 8oz squeeze bottle and thats worked out perfect for the garden application. It can be very messy working with such a large bag so recommended that you use it outside with good air flow.

    I moved out of a roach infested apartment, and my house doesnt have roaches, so clearly it works. Beware that this stuff builds up a strong smell in storage. Opening up all my boxes after the move sure was...an experience...

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.

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.

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.
