10 Uses for Diatomaceous Earth for Home & Farm

If you’ve never heard of diatomaceous earth before, it’s worth learning about! According to Dr. Josh Axe, “diatomaceous earth (DE) is a natural product made up of fossilized remains of tiny, aquatic organisms called diatoms. Composed of the cell walls/shells of single cell diatoms, it easily crumbles to a fine powder.” You can find DE in countless products, most often in powder or liquid form. It can be used in food-grade (safe for human consumption) and non-food grade (used in industrial settings), but we want to steer clear of the non-food grade stuff for the purposes of this post. Food-grade DE can be an impactful piece of your natural lifestyle and hobby farm. While there are countless benefits and uses, I’ve highlighted 10 for you here.

Body Detox.

Body Detox. DE can help detoxify your body and maintain optimal gut health by attracting harmful toxins and flushing them from the body. You can take about one teaspoon of food-grade diatomaceous earth with water once a day to detox. Drink plenty of water afterwards and throughout the day to stay hydrated. You can also mix it in with other things – juice, smoothies, yogurt, etc. – but make sure to still drink plenty of water with it. You can slowly work up to 1 tablespoon a day, keeping in mind that it’s best not to use it continuously for long periods of time.

Joint, Bone, Ligament Health

Joint, Bone, Ligament Health. DE has been shown to support bone and connective tissue health. Take it orally as described in step 2 to fight against osteoporosis and other bone disorders.

Kills Parasites and Viruses for Humans

Kills Parasites and Viruses for Humans. Taking DE as part of a detox process can also kill parasites and harmful viruses to improve overall health.

Teeth Whitening.

Teeth Whitening. DE is a gentle abrasive so it can help to clean and whiten teeth. Simply sprinkle a bit of the dust over your toothpaste every so often for a deep clean. This is not something you want to do continuously so as to not harm your teeth’s natural enamel.

Plant Healthy and Growth

Plant Health and Growth. Add DE to potting soil to help it retain moisture and nutrients, allow oxygen to circulate freely, and fight off parasites.

Indoor Pest Control.

Indoor Pest Control. DE removes the waxy outer layer of insects’ exoskeleton which helps them maintain moisture, thus causing them to dehydrate. Use it on carpets, upholstery, or anywhere else you think bugs or pests may be lurking. Brush or vacuum the area first, then spread a light film of DE over the whole surface. Leave it for 4-12 hours and then vacuum. Repeat weekly for 3-4 weeks. You can also spread it around the outside of your home or in other areas inside where pests like spiders and ants show up. Safer and cheaper than harsh chemicals!

Natural Garden Pest Control.

Natural Garden Pest Control. DE is best used dry. Lightly sprinkle it where slugs, Japenese beetles, or other unwanted pests will come in contact with it. Make sure to keep it away from insects that you do want, like bees. It’s not as effective when wet, so refresh your treatment if the area gets wet.

Animal Health.

Animal Health. DE is helpful for keeping unwanted pests away from your animals. Include DE in your chickens’ dust bath to prevent lice or in your animals’ feed as a natural way to fight off fleas, worms, and other parasites. You can also give your indoor pets (or their beds) a light dusting to help fight against fleas and allergies. I also like to put down a like layer of DE in the bottom of the coop and in nesting boxes after cleaning and before bedding is added to help prevent mites and lice.

Skin Exfoliation.

Skin Exfoliation. DE can be a great exfoliator every once in a while. Use it as part of a facial scrub or mask by mixing 1 tablespoon with water, milk, or diluted honey to make a thick paste. Massage it into your face in circular motions and let it set for 1-2 minutes before removing with a warm washcloth, again in small, circular motions.

Food Preservation.

Food Preservation. Mix a small amount of DE in with dry grains, legumes (about 1 tablespoon in a 5-gallon bucket of grain) to prevent weevils. If you’ve ever had weevils you know how frustrating they can be to get rid of!

How Do I Get Diatomaceous Earth?

You can get DE in most hardware/farm supplies stores and you can even get it on Amazon. It’s not super expensive either which means that you can use it in lots of different ways without breaking the bank.

I’ve done a lot more with DE when it comes to animal and plant health in my life but I’m looking forward to trying it more when it comes to personal health.

Have you tried DE before? I’d love to hear about your experiences using diatomaceous earth in these or other ways. Let me know what works for you and what you’re doing to live naturally. Here’s to a happy and healthy 2019!

  1. So I bought some DE and I didn’t realize did I bought the non-food grade. I can’t find anywhere that says what to do with the non-food grade. I was getting it to use in my garden.

    1. It’ll work ok in the garden, just wash your veggies and such. It has some other caking agents and stuff in it.

  2. How do you use it on pets for fleas. Do you dust them or put it in their food and how much and how often.

    1. I would assume you’d put it on the coats where the fleas were but do more research, it’s not at all good for you to breath in and can really irritate your lungs. I don’t know how you would apply it without having a pet breath in the dust. Proceed with extreme caution.

    2. Dosage
      Internally in dogs, give these amounts:

      Small dogs and puppies: 1/2 tsp per day in food
      Up to 50 lbs: 1 tsp per day in food
      Over 50 lbs: 1 Tbsp per day in food
      100 lbs or more: 2 Tbsp per day in food
      It’s best to mix it with raw or other moist food. If you feed dry food, add some water or broth to moisten the powder.

      For external pest prevention, rub the powder into your dog’s coat. Start near the tail and pull back the hair to get it on the skin.

      Avoid the eyes, nose and mouth as it can irritate mucous membranes

  4. I love diatomaceous earth indeed! I drink it every day, although I am pretty healthy, I have noticed my hair is thicker and my nails dont brake as much. I follow Dr. Axe suggestions on health and I share his knowledge with many people I come in contact with. Thank you so much!


  5. For detox you say not to take for a long period of time. What is a long period of time? Should it be taken as an on ond off period of time?

  6. I’m a week in at 1 tsp. A day first thing in the morning. I hoping to help with cholesterol and weak hair and nails. I will check back in a month.

  7. Wonderful product. Love it for detox & on my pets to get rid of fleas. Also, really good feeling when I wash my face with it.

    1. Hi Herminia, I’m also interested to see how it works for you. Because my daughter is a type 1 diabetic since she was 8 years old. And her hair is super thin and breaking off and falling out and her nails also are not all that good and I’m sure she has some cholesterol issues. So I would like to hear how your results are in a month. Sincerely, Debby

    2. Bobby, you said that you used it also on your pets.Do you happen to have a cat that you use it on also? Because my cat is an adult cat and he has long hair and he is also an indoor outdoor cat which he carries in all sorts of crud and critters and it’s driving me crazy because I have all sorts of mites in the house! So I’m anxious to hear if you have a cat that you also put it on.

    3. I tried to make contact close, like dip a cup in a put the cup right next to their fur if that makes sense, don’t sprinkle it and let it float around, put it right where you want it to go.

  8. Wonderful! I love the flow of this post, howr it was written, and how informative it is! Thank you. 🙂
