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 Jennifer,
    Yes DE takes care of worms in horses. The amount is 2% mixed in their feed. Here is a link with more info

  2. Jennifer Jennifer

    Hi! Does DE help with worms in horses and if so, I’m wondering what the dose is for a 900lb horse ?

  3. -Louise's - -Louise's -

    Hi Brock
    Make sure you are feeding them enough DE. If they are adult cats then I would feed two teaspoons each depending on their weight maybe two heaping. The only problem with feeding them too much is they will get constipated so if they do then just back off a little. Depending on what type of worms they have you may be getting rid of them but they are getting re infested again. If the source of the worms isn’t gone then you want to keep feeding the DE until the source is gone. You can continually feed DE with no breaks.

    I have been feeding my cats DE since November 27 and I still see some residue of worms in their feces and my cats stomach still looks bloated. My 30 days will be over on December 26. When will I stop seeing residue of worms in my cats feces and when will their stomach return to normal?

    Hi Chris,
    When you say a little bit every day, make sure it's enough for her body weight. Yes, if you are giving her the correct dosage it will also help with anal glands. If she is experiencing a problem with her anal glands you can also just give her some raw broccoli florets. We recommend not to express them because it's best for them to let their body do it naturally.

  6. Chris Chris

    I have an 8yr old Yorkie and have been giving her D. Earth for over a year. Just a little bit every day and have never seen any worms. Does it help with anal glands. Thanks very interesting.

  7. Stacey Stacey

    Hi, I recently recieved my Diatomaceous Earth. I originally bought it for my dogs who have been having issues because my yard is all dirt and grass doesn't grow. I have several cats most are over 5 lbs except for 2 of them and I recently notice worms. They sometimes eat from each others food dishes whether it is wet or dry food. Whats the best recommendation you have for multiple cats?

  8. Kiana Kiana

    Hi Louise,
    My 2 year old cat ran away for several months & last month she reappeared with 3 kittens in tow!! They had fleas really bad so we treated all of them with an OTC flea killer but now we've noticed that mama cat, Rizzo, has some kind of worms... not sure if it's tapeworm or pin worms... they look like little blobs or bits of rice in her anal area & on the underside of her tail. Because she, the 3 kittens & our small dog all drink from the same water dish (and occasionally sneak each other's dry food as well!) I wondered if it would be ok to mix the DE in their water dishes or if it needs to be added to the dry food? Any help is much appreciated!

    Hi Erika,
    Every animals case is individual as to what you may or may not see. A healthy stool is soft with form not hard. Sometimes you will see worms dead/alive and sometimes you may not see anything but they are passing them so don’t worry. The normal dose for most cats is 1 - 2 teaspoons depending on the cats size. We normally try to go on the high end when we are deworming just to make sure we are giving enough. If they get constipated then back off a little because you are giving too much. DE usually kill most worm in 7 - 14 days but we usually recommend to feed for a minimum of 30 days. Give us a call if you have any questions 407-688-1026.

  10. erika erika

    Hi I would just like to ask what to expect during the duration of treatment with DE. Do the cats usually frequent the litter box? Is their stool supposed to be soft or should they be the normal, hard ones? Should I expect the worms that come out with the stool already dead and should I be worried if some are not? I'm on the fourth day of giving them DE and I'm not sure if it's not working or I'm just not giving them enough or if it's just too early to see results yet.

    Hi Tabitha,
    Yes you can feed it to mom when she is pregnant or nursing. When the babies start eating on their own start feeding it to them as well.

  12. Tabitha Tabitha

    hi, i wanted to know can i use Food Grade De on a cat we took in because she was pregnant, which she just gave birth this Saturday, at 7 am. I did not give her food grade de while she was pregnant, but now that she is nursing i wanted to know would it be ok to give to mom now? i was researching but was still not sure, because some say yes to give to mom now and when the kittens start eating solid food then give to them, while some have said not to give while nursing. Please help would greatly appreciate it.

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

    Hi Brooke,
    It can be worms but it can also be so many other things like thyroid, heart or kidneys. We would take him to the veterinarian to do blood work and to get a diagnosis and then go from there. Please feel free to give us a call when you find out.

  14. Brooke Brooke

    Hello, we have an adult cat that has recently lost quite a bit of weight and has more “pronounced” breathing. Like it looks as though he is purring but is just breathing. Our guess is that he has worms, I have not wormed him chemically, last time
    I did he got quite sick. We started him on De yesterday. Do you have any other recommendations? Do you think this sounds like worms, or could it be something else? Thanks for your time

  15. -Louise's - -Louise's -

    Hi Caroline,
    The DE will definitely not hurt and yes I would feed it (1 Tbsp daily - 1 meal) but it may or may not get rid of the coccidia. When we have coccidia we recommend Kochi free, Peritan FP and Paxxin from Amber Naturalz. Here are the links

    If you need to go over this with us or need us to ship it to you give us a call 407-688-1026

  16. Caroline Caroline

    My 4 month old, 30lb husky has coccidia. Her bowel movements are normal and she has no symptoms. The vet wants to give her Baycox. I have been feeding her 2 tsp DE daily for 4 days. Will DE get rid of coccidia? Am I giving her enough? Thanks

  17. Dienne Dienne

    I have a 100+ lb mastiff with Giardia and I’m wanting to give him DE. Everywhere I search for dosage only states 2 tablespoons based on his weight daily with food. He is fed 4 smaller meals per day to heal his gut as he became quickly malnourished because his last vet failed to tell us he had it. Do I split the dosage between the four meals or is it given in one dose? If one dose, does time of day make a difference?

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

    Hi Adrienne,
    We feed DE continuously to our goat and cows and they are worm free. We have never had to deal with Barber Pole worms so I think it should work but I would definitely have them tested along the way to make sure you are feeding enough or that it is taking care of them. Keep in mind that if you have them in your environment they will keep getting re infested until you get them out of your environment. This is why we just feed continuously.

  19. -Louise's - -Louise's -

    HI Katie,
    No, it doesn’t have to be fed in wet food it will adhere to the dry. It’s usually just easier in wet food because it is a dry powder and some cats wont eat it that way.

  20. katie katie

    Hi we have a 15/16 yr old cat. Last 2 summers she has started to lay on our deck as she wasnt an outdoor cat before. This summer she has started to wander around the yard and have noticed a flea and looked like she has pin worms in one bowel movement. I fed it to her and she got a bit mucusy mouth. Is it suppose to be in wet food or water? My cat refuses all wet food and only eats dry. Thanks

  21. -Louise's - -Louise's -

    Hi Rachel,
    I would feed him a heaping tablespoon per day. Yes, it is also good to spread it in your yard. For giardia we also recommend Vibactra Plus and Paxxin from Amber Naturalz. Here are the links

    Feel free to give us a call with any questions 407-688-1026. Also, right now our website is just set up for local ordering so if you are not local then just give us a call to place an order.

    Hi I have a 10month old pitbull puppy that is about 46 47 pounds. He has just been diagnosed with giardia. He had 3 packets of panacur and now he is on the rest of his metro pill. I ordered DE - how much should I give him everyday and should i sprinkle in the yard? I just want him to be better - He just went poop this morning and its still looks a little soft to me and has the weird color. I also saw a white thing in it. And he does not have much of an appetite. :( help/

    Hi Linai,
    You can start feeding it to mom now and then when they start eating on their own add it to their food.

  24. Linai Linai

    How do you administer D.E. to 2 week old puppies when they are still only nursing from momma?

  25. -Louise's - -Louise's -

    Hi Mary,
    It sounds like he is getting re infected because your yard is probably infested. So yes you are going to have to stay on top of it until you get them out of your environment but it is possible. What is nice about the DE is you can feed it continually until they are gone and the DE does not hurt them. DE is beneficial for so many things a lot of people feed it all the time with no breaks. We would definitely recommend to feed the DE continually with no breaks until you know the hookworms are no longer in your yard/soil. Make sure you are picking up his stool and disposing of it which will prevent any new ones. You can also spread the DE all over your yard which will also help. We would recommend to feed a higher dose of DE since you are infested just to make sure we are clearing the worms. For 23 pounds we would do at least 2 heaping teaspoons.

  26. MaryJ MaryJ

    My seven year old rescue has been treated twice for hookworm. Most recent stool results early July were negative. However, he is again licking his anal area beyond what is reasonable. If I use DE to treat hookworm - would I see the worms being eliminated in his stool? He is 23 pounds; dosage would be 1 teaspoonful daily? He scrubs to cover his scent like a rototiller. If that is how he might be infected am I just fighting a losing battle even with DE because he will just become infected over and over?

  27. -Louise's - -Louise's -

    Hi Monique,
    We are so sorry for your loss. The normal dosage for goats and sheep is 2% mixed into their feed. When we know we are dealing with a problem we usually go on the high end just to make sure everyone is getting enough. You can also leave it out free choice and some will just eat it that way. You can tell if you are feeding too much because they will get constipated and then just back off a little.

  28. Monique Pierson Monique Pierson

    I recently lost my mama goat to lung worm so I want to start using DE on my herd of goats and sheep. They all eat together so how can I make sure they are all getting the right amount each? This is new to me and I don’t want to try and put chemicals down their throats. Thanks

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

    Hi Parisa,
    DE is not medication it is 100% natural so there is no need to be concerned about it. It naturally de worms pets but it also has many health benefits. We feed it to our pets and we take it ourselves. Here are some links which will tell you all about it.

  30. Parisa Parisa

    Hi! I have an adult cat who recently has been spending more time outdoors. He’s had diarrhea for several days now and I want to start him on DE to deworm. I’m just nervous about it. I’ve never given him any flea medication or dewormer before as he was an indoor cat up until recently. Any tips help. Thank you!

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

    Hi Andrea,
    Yes, the DE is ok to give with the powdered pumpkin seeds and apple cider vinegar but the DE will take care of it all alone without them.

  32. Andrea Morris Andrea Morris

    Hi guys! I just received my shipment of DE today (yay) for our puppy. I was giving him powdered pumpkin seeds with apple cider vinegar in his food to prevent worms. Are these ok to use with DE? I’m so happy my vet sent me your way. You guys are amazing!!

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

    Hi Beth,
    I would bump him up to a heaping tablespoon one time per day (if he gets bigger go to two). You can’t overdose but they will get constipated with too much so watch for that and back off if he does. I would feed it to him until you know for sure the fleas are gone because he is going to continue to get re infested. Keep in mind he can also get tapeworms from opossum poop etc.

  34. Beth Beth

    We adopted Duke, a staffy mix, in December. He had worms when we adopted him even though he had been given 2 rounds of dewormer. He is now 9 months old and we have been through 5 rounds of chemical treatment. Each time the worms go away for about 2 weeks and return promptly. I started him on DE this week adding 1 tsp to his food bowl every morning. He is still a puppy, but he's a 50 lb puppy. Is 1 tsp a day sufficient considering his age and weight? We have never physically seen a flea on him, but obviously somehow being continually reinfected. ANY suggestion is greatly appreciated!!

  35. -Louise's - -Louise's -

    Hi Linda,
    Yes, you can put it in the wet food and it is absolutely as effective. We usually recommend to put it in wet food because they don't notice it as much so it’s easier. It all depends on what type of worms they are on how long it takes to get rid of them (she may be getting re infested for instance if they are tape worms). If they are tapeworms and you have fleas then you want to keep feeding the DE until the fleas are completely gone. When we know we have worms then we give the highest dosage possible. For a cat I would try to get up to at least 2 teaspoons per day ( in one feeding ). Here is a link for more information

  36. Linda Williams Linda Williams

    I am giving my cat De Earth the dry food but he likes some can do I put it in the wet can food. I read that it is not every effective in the wet food. Is that true. Also how to you know that it's working I started on the 15th and I saw some coming out today on the 22th. I haven't seen any in her stool but they crawl out of him. Help!

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

    Hi Christina,
    While most worms do die off in just a few days we recommend to at least feed it a minimum of 7 - 14 days. It really just depends on what worms you are dealing with and the infestation level (If they are indoor or outdoor etc). Give us a call and we would be happy to help you out.

  38. Christina Christina

    Hi , I have 3 grown cats, I have never given them DE before, I was wondering for worms, if I were to give them DE for 30 days in a row, then is is effective thereafter to give them DE a few days each month? And if yes, how many days each month would you recommend after the 30 days? Most grateful for your response, Christina

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

    Hi Elizabeth "Jo",
    We usually just mix it in daily to the food. Cats are 1 - 2 teaspoons so we add that by the number of cats we are feeding to the daily food. We usually try to go up to the 2 teaspoons just to make sure everyone is getting enough. Some may get more than others but that is ok if you are feeding it every day. Here is a link for more information.

  40. Elizabeth “Jo” Elizabeth “Jo”

    Hello - How can I deworm a colony of feral cats I have trapped /neutered/spayed /returned to their colony ? I watched a video that said to put 1 cup of diatomaceous earth food grade in 16 pounds of cat food. Is this the proper. way to worm cats ?

  41. -Louise's - -Louise's -

    Hi Liv,
    Yes, it could be that or depending on the food she was on and what you are now feeding she could also be detoxing from that. If its pure liquid diarrhea you may want to fast her for 12 to 24 hours (make sure she has water available). I would absolutely continue the DE with no breaks. Feel free to give us a call if you have any other questions or if it doesn’t get better.

  42. Liv Liv

    I have recently adopted a 2yo cat and have been feeding her good quality wet cat food (no human food at all). She’s been with me for a little over 2 weeks and she’s had normal stool at first. In the last 4 days I have started to add 1 tsp of DE to her evening meal (she only comes out to eat once a day) and for the past 2 days she’s having diarrhea. Could this be the DE side effects due to deworming? Do I continue with DE or do I take a break? Thank you for your time.

  43. -Louise's - -Louise's -

    Hi Doug,
    2% is the ratio for most farm animals (chickens 5%) but when it comes to dogs and cats it is much easier to just add the correct dosage into their daily feed. Cats need 1 teaspoon per day and Dogs depending on their size 1 teaspoon to 2 tablespoons per day.

  44. Doug Doug

    I recently incorporated DE in the feeds of my horses and poultry. I also want to supplement my dog and cat feed for continuous worming benefit. I see the listed daily dosage recommendations, however, I’m trying to calculate the amount to add to bulk dry food. Is 2% the correct ratio for canine/feline? I typically buy 50lbs dry dog and 30lbs dry cat. How much DE should I mix into each bag? Any help would be greatly appreciated!

  45. -Louise's - -Louise's -

    Hi Katie,
    Read through the blog and it will tell you how to use the Diatomaceous Earth. Here is a link to our resource page that has more info on Diatomaceous Earth. Yes, I would start the mom on it now and then the puppies as soon as they start eating on their own.

  46. Leeanne Williams Leeanne Williams

    I have a 50 lb 7 year old border Collie that has white gums not eating and low energy how much de should I be giving her today? I also am giving her one cut carrot per day along with adding apple cider vinegar to her water and fresh coconut in her food. Please respond via email [email protected]

  47. Katie Katie

    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

  48. -Louise's - -Louise's -

    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.
