How to De-Worm Your Pet with Food  Grade Diatomaceous Earth

Are you dealing with worms but don't want to use the chemicals to deworm your pet? And now you just don't know what else to do? Did you know that 85 to 95% of the human population also has worms which is a major contributor to disease and illness.

Are you dealing with worms but don't want to use the chemicals to deworm your pet? And now you just don't know what else to do? Did you know that 85 to 95% of the human population also has worms which is a major contributor to disease and illness. We only feed our pets what we would eat ourselves so why would we give them a chemical that we wouldn't take ourselves? That's why we feed Food Grade Diatomaceous Earth.  We give it to all our animals and we even take it ourselves.


What is Diatomaceous Earth?


Diatomaceous earth (DE) is the remains of microscopic one-celled plants (phytoplankton) called diatoms that lived in the oceans and lakes that once covered the western part of the US and other parts of the world. These deposits are mined from underwater beds or from ancient dried lake bottoms thousands of years old. This means, diatomaceous earth has an unlimited shelf life provided you keep it dry. Our diatomaceous earth is organic OMRI listed Codex Food Chemical Grade. It is a non-treated, non-calcined fresh water Diatomaceous Earth. It is mined, crushed, sifted, bagged and pure white in color. It contains less than .5% silicon. There are food grade diatomaceous earth products that are yellow or tan in color which indicates a higher iron content. Those which are gray in color contain more clay. It is very important to only obtain food grade diatomaceous earth to use in and around your household.

As we’ve mentioned this supplement in our previous post for ridding your life of fleas this is how we use it internally. When food grade diatomaceous earth is fed in adequate daily amounts, it eliminates all intestinal worms and parasites. This helps the human or animal better absorb the nutrients from the food they eat, which in turn benefits them as a whole! De actually rids the body of roundworms, whipworms, pinworms, and hookworms within 7 days of being fed daily. But to be most effective, food grade diatomaceous earth must be fed long enough to catch all newly hatching eggs or cycling of the worms through the lungs and back to the stomach as De does not kill the eggs. A minimum of 60 days is suggested for most worms, 90 days is advised for lungworms and even sometimes double the recommended dose. Just remember, DE has to come in contact with the worm or parasite to kill it within 24 to 72 hours. Once you start deworming with DE you don’t want to stop or take any breaks otherwise the infestation of dead dying worms which emit bacteria and toxins can cause a toxic overload, which can make animals or people sicker. Really, you can feed too little, but you can't feed too much! In most cases the way you can tell if your dosing is a little too high would be if there is any constipation!


The dosing chart is as follows:


Kittens - 1/2 teaspoon

Cats - 1 teaspoon

Puppies - 1/2 to 1 tsp.

Dogs under 35 lbs. - 1 teaspoon

Dogs over 35 lbs. - 1 tablespoon

Dogs over 100 lbs. - 2 tablespoons

Cattle, Dairy Cows, & Hogs - 2% of dry feed ration

Chickens - 5% in feed

Goats, Sheep, Alpacas, & Llamas - 2% in grain

Zoo animals - 2% in daily feed

*Humans - 1 - 3 heaping tablespoon daily


We recommend starting slow and increasing as desired, after you are certain you aren't having any heavy detox effects. Because DE is a safe non-toxic natural dewormer, with no chemicals to it, worms can't be immune to it!


Whether it's for you, your pets, or even your home DE has a wide variety of benefits! For one it can help to boost and build immune systems which keeps your pets happy and healthy with the added bonus of a soft and shiny coat! It’s also used to detox any heavy metals out of the blood and even things like e coli and other harmful bacterias and viruses! In humans it's used a lot to stabilize blood sugar levels and lower cholesterol and blood pressure levels! With over 15 trace minerals in its makeup DE is great for everyone!


Diatomaceous earth has so many more benefits than just deworming!

But more importantly the benefits of DE mean reduction in vet bills and disease! All in all you and your pets will have a much healthier life!

    Hi! I have a Basset Hound that just had 12 puppies. Can you give me info on how to use this. Do I start mom on it now? And puppies later? Will puppies be treated through mom's milk? Thanks

    Hi Diane,
    Whipworms are very hard to get out of your environment so you need to continually feed the DE until you know they are gone from your environment. If feeding the DE continually you will be getting rid of the whipworms from your dogs but they will keep getting re infested so they will probably test positive until the whipworms are gone from your yard. The amount for a 67lb dog should be at least 11/2 tablespoons not teaspoons. Since you are infested we would recommend to get them to at least 3 tablespoons just to make sure you are giving enough because we want to make sure we are killing off the worms they are getting. The only side effect of giving too much is constipation so if they get constipated back off a little. We had whipworms once and was told we had to remove at least 2 inches of soil to get rid of them but instead because we live in Florida we just cut the grass really short and let the sun kill them and it worked. It took us about 6 to 8 months to completely get rid of them so be patient. We would also recommend to feed the DE at least another 3 months after you know they are gone just to make sure you don't miss any hatchings.

  3. Diane Voeller Diane Voeller

    I have the DE and I have been giving it to my two standard poodles My female that doesn't eat dirt is fine but my male eats dirt all the time and I know he still has worms they both weigh 67# I give them a 1 Tsp and 1/2 should I increase the dosage or what else can I do with them they proved positive for whipworms went through two rounds of vet drugs that didn't work??

    Hi Trisha,
    Diatomaceous Earth eliminates roundworms in 7 days of being fed daily but we recommend to feed for a minimum of 30 days. DE does not kill eggs so due to the life cycle of roundworms you want to make sure you are getting all the hatching eggs. When we rescue a puppy we feed it for at least 6 months just to make sure we get everything.

  5. Trisha Trisha

    My 12 week old puppies have been on DE daily for a month. I am seeing roundworms in their stool and they have vomited some up too. How long does it take to get rid of them?

    Hi Marney,
    We have used DE for years and have had thousands of customers also use it with proven results. It absolutely does work on tapeworms. Tapeworms come from fleas, opossum poop etc. so you have to continually feed the DE until you get rid of the source/fleas completely because your dog will keep getting re infested. There may be some confusion on how DE actually works. DE is not a preventive where they will not get worms, it gets rid of the worms once they get them. Your boy shed the roundworms because the DE was working. You mentioned that you were giving 1-2 tablespoons per day but for a 120lb dog we would recommend to do a minimum of 2 tablespoons per day. I hope this helps clear things up so you can feel confident and not bummed that it is working and you do not have to do the chemical dewormers.

  7. Marney Marney

    DE is great but does NOT work on tapeworms. They have hooklike heads that burrow into the intestinal walls and segments just keep breaking off and growing back. It’s well-known DE doesn’t help here. As for other worms, I’ve been giving 1-2 Tablespoons every morning to my Cane Corso. He’s 120+ pounds and I’ve given it to him pretty much his whole life... no chemical dewormers except to rid him of the tapeworms he came with. He’s 14 months now. I was completely shocked to see a long roundworm come out in his stool a couple of days ago! He gets DE daily! Vet confirmed the roundworm and put him on one dose of Interceptor. My boy had also lost 4 pounds. I won’t quit the DE, but I can now say it’s not a sure fire preventative. Really bummed.

    Hi Brey,
    It wouldn't hurt it to add it in while preparing but I'm not sure what it will do to the consistency so you may want to try both and see which they like better

    Hi Jennifer,
    I’m not sure if you're asking for humans or animals but it's the same for both. It all depends on your environment/risk factor or if you're taking/feeding it for a specific reason. A lot of people just feed/take it continuous with no breaks and that is perfectly fine. We usually take/feed it for at least 6 months and then we will take a break for a little while and then start it again for another 6 months. There is no right or wrong, I would just make sure that when you do take/feed it that you do it for a minimum of 1 month.

  10. Jennifer Jennifer

    Hi I was wondering after the initial 90 day daily regiment how frequently/ or what should a deworming schedule look like? My doctor insists that parasites are rare in the human population today. I disagree as I grew up on a farm with horses, chickens, goats, rabbits and the occasional cow. . . That doesn't include the dogs and cats that were in the house. . . Which were all wormed, generally on consistent schedules. Thank you

    Hi Madelon,
    Yes, feeding Food Grade DE will get rid of Giardia. Depending on the severity we also recommend Vibactra Plus and Kitty DT from Amber Naturalz. The DE doesn’t have to be exact just make sure it is enough. When you mix it into a group feeding then mix the total amount for all of them into it, some will probably get more than others. We usually start with the 1/2 teaspoon for kittens and then try to work up to a teaspoon per kitten. You can tell you are giving too much if they get constipated so if they do just start backing off a little. If you are not local we do ship just email us or call us with your information. Here are the links

  12. Madelon Madelon

    Hello I have 7 week old kittens with Giardia. Will this get rid of giardia? Can I just mix it in the food bowl for all of them? Does it have to be an exact amount?

  13. -Louise's - -Louise's -

    Hi Jacquie,
    It's 2% of your food mixture when mixing it all together. If you feed daily and separately then it would be 2-3 tbsp per 100lbs.

  14. Jacquie Jacquie

    Hi I have 6 pet goats and want to start treating them with DE. It says on your dosage chart 2%, I’m probably being a bit dim but 2% of what? Thanks

    Hi Nissa,
    Read the blog and it will go over how to get rid of tapeworms using food grade diatomaceous earth. Here is another link that will also help you.

  16. Nissa Nissa

    My cats have tape worms but I can’t personally put the pills down their throat’s and I’ve tried the liquid in their food and they won’t touch it. Is there a different way that I can get rid of these worms like her over the counter shot that I can give them? Without a prescription I’m a single mom and I can’t afford to take all of my cats to the vet .

  17. -Louise's - -Louise's -

    HI Cathleen,
    It all depends on what you are feeding/taking it for. For a lot of worms it only takes 7 days but for some it takes 30. We usually recommend to feed it a minimum of 30 days but you can take/feed it non stop if needed. Here is a link to more info on DE.

  18. -Louise's - -Louise's -

    HI Cra

    Yes, feeding Food Grade DE is great for Giardia. Depending on the severity and since you have done two treatments already we would also recommend Vibactra Plus and Paxxin From Amber Naturalz. We also would recommend to spread the DE in your yard. If you are not local we do ship just email us or call us with your information. Here are the links

  19. Cra Cra

    I have a 8 month old French bulldog that has gone through 2- 10 day treatments from the vet for giardia, I have heard the DE will work for that, is it true?

  20. -Louise's - -Louise's -

    Hi Teresa,
    You can just mix it in the food. Canned food usually works best but it will adhere to dry. The normal recommended dose for a cat is 1 - 2 tsp once per day.

  21. Teresa Teresa

    Looking forward to helping our young cat who doesn't like taking the veterinarian prescribed medicine. What should I mix the DE with and how should it be administered? Thank you!

  22. -Louise's - -Louise's -

    Hi Maureen,
    If you have fleas then yes doing their bedding is a good idea. It is very good for you and your body to make sure you drink enough water on a normal basis but it is not necessary to drink more because of the DE. The De does not dehydrate you internally.

  23. maureen grant maureen grant

    hi and thanks for all this nfo. i have just i inherited a semi wild 4 wk old kitten (maybe 4 others will follow and if lucky mum cat) i have just mixed in the half tdp of DE in with her milk lactose free which she took no bother. I will continue for 6 months as suggested and also my new eight yr old cat even though i reluctantly fell for the vet suggesting the pill!). so i guess i should also do their bedding just in case? btw coconut oil is great too also dr bruce fife coconut oil pulling book for human teeth and more). and re the De ive heard drinking lots of water is a good idea i guess to stop dehydrating post De?

  24. -Louise's - -Louise's -

    Hi Rita,

    What I would do first is treat my house and all of their bedding with DE. Here is the link to help you with that.

    You can put the DE right on the cats, simply sprinkle it down their back and go with their fur so you don’t create a cloud of dust. If it’s on their bedding and on them they will get some DE into them that way when they clean themselves which can only help.

    The amount you need to get into each cat is approx 1 - 2 teaspoons so when you have so many cats the easiest way is to just make sure you are using more than enough. I would first try to just add it to the can food but if you have to then it will adhere to the dry. You can also try other things like giving them a treat of goats milk or bone broth. We have 11 cats who eat all together on trays and when we feed them the DE we just mix the whole amount of DE for each of them in it knowing some will get more than others. The way you know you are over doing the DE is constipation so just watch for that otherwise you can’t really give too much. Keep in mind you will be getting rid of the tapeworms but they will keep getting re infested as long as you have fleas. You need to continue to feed the DE until all the fleas are gone. For your dog they are usually pretty easy, just add it to her/his food if you feed canned or like I said it will adhere to the dry or you can give them a treat of canned, goat milk or bone broth. Here are a couple more links on Diatomaceous Earth

    Also, just wanted to mention we also have some great products from a company (Amber Naturalz) that we swear by for Coccidia if ever needed in the future.

    Hope this helps
    Good Luck!

    I have a large number of indoor cats and kittens. 17 adults, 5 kittens at 6 months old, and 3 kittens at 3 months old. All are rescues. Plus I feed the outside ferals and strays in the neighborhood.
    I've had a recent battle with coccidia here and 3 of the youngest kittens didn't survive. The other 3 are now energetic and regaining weight. The kittens were only 3 weeks when I rescued them and their feral mom. I chose to let her continue to nurse them instead bottle feeding and having mom spayed and flea treated at the time of capture, like I would normally do. Big mistake.
    Now I have a house full of fleas and tapeworms. Panacur seems to have handled the roundworms, but not the tapeworms. And of course, though everyone is now on advantage, except feral mom, who gets comfortis (like advantage, but given in food monthly), the tapeworms and fleas in the house must be dealt with.
    I have bombed the "sick room" where the youngest kittens are recovering, and the kitten room where the older kittens are. I can't use bombs in the main house or the room currently housing the feral mom. So, I am using de and vacuuming those areas.
    My problem is the logistics of getting enough de into everyone for worms, in a communal environment where they free feed on dry food and get wet food twice a day (except the 3 month olds, who freed feed on wet food too, as much as they will eat..and they are eating like horses). Everyone also gets home cooked chicken and broth at least twice a week, but not everyone eats that. And not everyone eats the wet food served every time. Some will only eat the fish varieties, while others will only eat the chicken varieties. Not many care for the beef varieties that are also included in the variety packs, but I still serve it occasionally, but more often to the outside cats, who aren't as finicky. And a few eat dry food almost exclusively. Also, even though everyone is given their own dish of wet food, they go from dish to dish. Some eat more than others. And some refuse to eat if they don't care for what's being served. I also have an 80lb pit bull rescue who likely needs worming now with de as well.
    I would be very grateful for your advice and help to figure out how to get this massive job done.

    Hi Cheryle,
    Cats need at least 1 tsp per day. Depending on his size I would increase accordingly (heaping tsp to 2 tsp per day) to make sure he is getting enough.

  27. Cheryle Cheryle

    Just started feeding a feral Tom cat. Sure it has parasites and worms. Been outside long time. How much DE food grade do I put on food. Will not be able to monitor do not see cat throughout the day?

  28. Melissa Melissa

    How much would I start off using on a kitten 13 weeks old? For how long before increasing to Max amount? For example: 1/2tsp for a week, if no probs then increase to 1tsp? He was under weight (1.5lbs), when I got him 3 weeks ago but vet put him on dietary supplement & pretty sure he's weighing what he should be now.

  29. -Louise's - -Louise's -

    Hi Carolyn,
    I would recommend to not mix it in the whole bag and to just mix it in daily to there food. If you put it in the whole bag then you are not going to know if they are getting the right amount daily. Kittens need 1/2 to 1 teaspoon daily and adults need 1 to 2 teaspoons daily to get rid of worms. To get rid of the fleas I have attached a couple of links for you.

  30. Carolyn D'Orazio Carolyn D'Orazio

    Hi, I'm trying this for fleas on my indoor cats!! Don't know how they got them in the first place. How much DE can I put into a three pound bag of dry cat food?


  31. -Louise's - -Louise's -

    Hi Gabrielle,
    The DE doesn’t really have a taste, its just chalky/gritty. It will adhere to the dry food so I would just try that first because a lot of animals will just eat it like that. If that doesn’t work then I would try to find something that they will eat or drink that I could mix it in. Some suggestions are can food, goat milk, bone broth, freeze dried (I would actually keep this dry because dogs and cats love it dry and it will adhere to it) I hope this helps a little and give us a call if you need some suggestions on cans for your cats.

  32. Gabrielle Gabrielle

    I am well aware of the many many things DE has done for animals (& people). I finally got some but my question is: HOW do I give it to them?
    My dogs (106lb & 50lb) eat dry food but they are amazing at taking pills (doesnt matter how gross it may taste, I can hand them their pill & they crunch it up & swallow all of it).
    As for my cats, they both eat dry food but 1 of them is extremely picky - she only will drink running water, and doesnt even like tuna.
    How should I go about giving each of them DE?

  33. -Louise's - -Louise's -

    Hi Tamie,
    When used externally it is ineffective when wet to kill bugs but as soon as it dries again it works. The reason it doesn’t work when wet is because DE is actually very sharp and when dry it slices the bugs exoskeleton and they dehydrate and die. Internally it works in a different manner.

    DE has been used and tested on animals as a natural dewormer for decades. It is the only dewormer we ever use on all of our rescued farm animals, dogs and cats. It absolutely works, no question. Here is a link for more info on DE

  34. -Louise's - -Louise's -

    Hi Brittany,
    The dosages are per day but do it in one meal. When you are deworming you may see them come out or you may not and sometimes there are days in between. I would continue to feed the DE just to make sure he is completely cleaned out. Also, if they are tapeworms then continue to feed until the fleas are gone.

  35. Tamie Tamie

    I LOVE DE, but I am not certain if it kills worms in animals. People claim it does, but has anyone ever tested an animal before an after? What baffles me is that it is stated clearly that DE is ineffective when wet. if that is true, then how can it work inside the body to kill worms?

    I am caring for 20 cats and I am certain that a few have worms right now. It will save me a butt-ton of money if I can worm with DE, but I do not want to waste time on it if it is not going to work.

  36. Brittany Brittany

    Are those dosages per day or per meal? My older kitten already has dewormer from the vet but I just started adding DE to his food with a spoonful of pumpkin (also because he's on antibiotics for a separate issue). He already had a worm come out in his stool a couple of times before even starting dewormer or DE, and once he did start only a few more worms came out and the last couple times no worms we're in his stool... I'm not sure if that means he only had that many inside or if he needs more dewormer or something else.. Any idea?

  37. -Louise's - -Louise's -

    Hi Colleen,
    The diatomaceous earth will definitely help them. It may or may not completely help with what you have going on right now but it definitely will not hurt and it is necessary because I’m sure they all have worms and getting them started on it is a great idea. If they are four weeks then I would also start to make a slop with a good can food ( I’m not sure where you are located but either come in or check out our site for some good brands and we do deliver) I would mix the can food with a good raw goat milk because that is much healthier than most formulas out there. We also have a product from Amber Naturalz called Kitty DT that is awesome to help neutralize their digestive tract and get rid of the diarrhea. Here is the link for it.
    If you have any further questions please don't hesitate to give us a call 407-688-1026

  38. Colleen A Nungesser Colleen A Nungesser

    I have orphaned 4 week old kittens. The person who was watching them before outside fed them things they weren't ready for. Not even 24 hrs into having them, on formula only for now, they have developed diarrhea in all sorts of variations. Do you think diatomaceous earth will help? 2 of 3 are very playful despite their sore bottoms and diarrhea and eat when fed. Trying not to over feed. I feed til they really resist. The runt is eating and will walk around but not as playful as the others. Not necessarily lethargic. Gums look good. Any and all suggestions and help welcome. Thank you!

  39. -Louise's - -Louise's -

    Hi Sarah
    Yes, it absolutely works on tapeworms. The problem with tapeworms is that they mainly come from fleas so they will continue to get re-infested if you still have fleas. I would recommend to continue to feed the DE until you know the fleas are completely gone. Here is the link on how to get rid of fleas with DE

  40. -Louise's - -Louise's -

    Hi Reena,

    Diarrhea can be caused for many reasons. It's the body's way of getting rid of toxins so it just depends on what is causing it. The most important thing is to make sure you are feeding a good diet. Check out our website for choices of good companies that do things right. That being said the DE will also help no matter what the cause. Feed the DE in 1 meal. I'm not sure if your cat is a kitten or adult but if its a kitten start with 1/2 tsp and work up to 1 tsp and if it's an adult start with 1 tsp and work up to 1 1/2 - 2 tsp.

  41. Reena Reena

    Hi Louise and Others,

    Could you please advise how long until the diarrhoea stops in Cats?

    He's had diarrhoea for 3 weeks, I've only started giving him human grade DE (half a tsp) for 2 days now - 1/4 tsp in food once in the morning then once in the evening, however should I be giving him the DE all in one go instead?

    I'm trying to work up to 1 tsp during the week. Any advise would be much appreciated.

    Warm regards,


  42. -Louise's - -Louise's -

    Hi Crystal,
    They all need to get 1/2 to 1 Tsp each, depending on their weight. If you feed them all together then I would go on the higher end (maybe even a little more) and mix it in really well to hope they all get the right amount. Make sure you follow the dosage chart and increase accordingly as they grow.

  43. Crystal Crystal

    I have 14 puppies they all have worms how much do I put in food to slit between all of them should I put 1 tsp in the food

  44. -Louise's - -Louise's -

    HI Colleen,
    I don't think it has anything to do with the DE so keep doing the 1/2 teaspoon. It sounds like your puppy is just eating too fast or simply not chewing his/her food. When you feed make sure you spread the food out to slow him/her down. An old dinner plate usually works well.

  45. Colleen Colleen

    On 2nd day feeding my 9 month puppy 1/2 teaspoon, 1x day, DE in wet food. A huge vomit, with partly digested pellets. Is this a normal side effect? should I reduce dose?
