One of the most asked questions that we get is what should I use to worm my pig(s) and when should I do it. Also, why do I want to use a wormer when they have mange mites?

Most wormer's will also kill the mites that cause mange. The most popular and easiest to use is a liquid called Ivomec 1% Solution for Cattle & Swine.

A number of the sanctuaries have switched to Dectomax as it claims to provide protection for 21 days while the Ivomec protects for 14 days. Dectomax, like Ivomec, comes as injectable which can be given orally, and as pour-on which is put along the pigs back like the Frontline dog and cat products.

"I have used Dectomax with no problems, but I can't say it was any better than the Ivomec and it is more expensive." Ted of Willow Ridge Sanctuary

Another question is: What if my pig has never been wormed? No one has ever mentioned that I need to do this.

This does not fall under the rule of "If it's not broke don't fix it." It does not hurt them to be wormed. Most of us don't talk about the worms enough because the Ivomec and Dectomax that we use mainly for prevention and treatment of mange also kills worms and lice.

If they are on the twice a year schedule (spring & fall) then worms are not a problem because we are taking care of it when we Ivomec them.

If your pig doesn't have worms he will just pass the excess Ivomec out of his system. If he does have them you will certainly know as those are some of the nastiest things we have ever seen come out of a pig!

"Some of the rescue pigs that have come in have passed these terrible looking things after their arrival and their first treatment with the worming, but I believe that the twice a year schedule keeps them pretty clear after that." Phyllis of PigPals Sanctuary

The only worms you will see after worming is the large roundworms which can be up to ten inches long and thick as a pencil, although they are usually much smaller.

They will be lying on a pile of poop. They will pass from one to three days after medication depending on the regularity of your pig. Meds can be given before, during or after a meal it doesn't really matter.

We do not recommend worming the young ones that have worms. It is best to feed them better and worm them when they are 15-20 pounds or more.

Pig worms are species specific so don't worry about the other animals. A word of caution here; A worming schedule of twice a year is adequate for most pet pigs and the products talked about here are for pigs ONLY! You will need to check with you vet as to what is best for the dogs and any other animals that you may have.

On very young pigs you can dust them with Seven Seven powder like you use on your garden (you can get this at your local garden supply), or in the case of bad mange you can use this to kill the mites on the outside and relieve the itching until the Ivomec can work. Make sure you do not get the powder in their eyes or mouth!

This is meant to help with the itching, but you will still need to worm them with Ivomec to kill the mites that are in the larva stage.

If you don't have any Seven Seven dust at home try the feed store for some hog dust. The dust will help give relief on the itching while the Ivomec is working to kill the mites from the inside.

Everyone has their own way of giving Ivomec. If you go to the vets he will want to give a shot. Pigs don't handle shots very well so ask if it can be given orally. We give 1cc per 50 pounds of body weight. Ivomec is one of the safest drugs out there and has a wide margin for safety.

If your pig will sit nice for a treat then you can just squirt it into the side of their mouth. (Make sure it is the side of their mouth, not straight down their throat, so it doesn't go down the wrong tube. You also need to take the needle off of the syringe.)

Or you can dampen his food just a little and squirt the Ivomec on the food and stir and they will usually eat it. If you have more than one pig keep them separated so that you makes sure each pig gets his full dose.

"Yes, I put it in my pig's food when I give it. Make sure you are giving enough as these pigs grow fast and it doesn't take a little more when you do it by mouth. I cut the food in half, dampen it a little with juice, then squirt the Ivomec on the damp food and stir it up. By cutting it in half you are making sure that they clean it all up and are getting the medicine.

Then mark it on your calendar and 14 days later do it again. (This is for the pigs that have mange.) We do this on the outside pigs every spring and fall and it keeps thing pretty much under control until some new kid moves in that has it." Phyllis of PigPals Sanctuary

Ivomec 1% Solution is an injectable that most of us give orally. You will need the solution, syringe & needle. We use either an 18 or 20 gauge needle. The needle is needed to get the Ivomec out of the bottle. You take the needle off when squirting in the pigs mouth or on their food.

If you use Ivomec it will work for those mites in the ears as well as anywhere else. (Ivomec is not picky about what part of the body it works on as it goes into the blood stream and goes all over the body.)

Also, for chronic mange you can give every 5 to 7 days for up to 4 weeks. It is hard to overdose on Ivomec. For a "normal" case of mange you give two doses about 10-14 days apart and that is it. From then on you will want to worm your piggy twice a year (spring & fall) as a precautionary measure.

It usually takes that second dose to get the larva stage of the mites that haven't hatched yet. BUT, make sure you do it twice 14 days apart!

It is a good idea to change bedding when you are done with the 2nd dose even though the medication will kill any new mites picked up.

Can a human get mange? If so, what would it be like? Mange on a human is usually an itchy red rash...REALLY ITCHY!! You shouldn't have to worry too much about that as most cases on humans happen when the pig is really loaded with it and people take them to bed with them. The mites don't like us as well as the pigs so it's usually a light case and will go away on it's own with simple nothing.

They really don't like us too well and will leave on their own. Washing with alcohol might help with the itching.

TYPES OF WORMERS: Worming & Parasite Control

A variety of products can be used to treat your pigs. Listed below are few:

Ivermectin - Used to control worms, lice and mites. Can be administered in many forms.

Ivermectin Injection for Swine - This is a 1% injectable solution. It can also be given orally although this is an off-label use. A syringe and needle is needed to extract the solution form the bottle. The smallest bottle is 50 ml. so it is not cost effective in worming just one or two pigs.

Ivermectin Paste Wormer 1.87% - This product is designed for horses or equine but can be given to pigs at the same dose. It is relatively easy to administer on a piece of apple or the pigs favorite food.

Ivermectin Granules - A feed additive that is mixed in with the food over a six day period. It can also be used to top dress feed to treat a specific problem. Sold in 50lb bags.

Ivermectin Pour-on - A .5 % solution which is administered along the backline similar to flea treatments used in dogs and cats. The smallest container sold is 250ml which will treat 25 to thirty pigs.

Dectomax - A drug similar to Ivermectin, but claims to have a longer residual life. Also controls lice and mites and can be administered several forms.

Dectomax Injection for Swine - An injectable solution that can also be given orally.

Dectomax pour-on - A solution administered along the backline as the Ivermectin pour-on.

Heartland Wormer- a feed additive specifically designed for pot bellied pigs.

In addition to a regular worming schedule, effective pasture or backyard management can help to reduce the parasite load on your property. This would include removing manure on a regular basis. If manure cannot be picked-up, periodic raking or dragging the pasture will break-up the manure exposing it to sunlight which will help to kill the eggs.

Recommended places for finding Ivomec and Dectomax:

Jeffers Equine
Valley Vet

Don't forget to check with your vet and local feed store.


  1. I just wanted to say thank you so much for all the wonderful information. My 2 piggies are a bit bigger than potbellies. Spig, my 6-year-old female is about 600 pounds, redhaired, feisty (I said redhead, didn't I? :) ), and she's Daddy's Girl. Shadow, 4.5-years-old, my 800-pound neutered, salt-n-pepper haired male is a big ol' teddy bear.

    I wormed them both, orally with Noromectin, for the first time 2 weeks ago, and they both had more energy instantly. I just discovered what I believe from doing some research to be mange on Shadow's tail and right rear foot. It's crusty and scaly, although I haven't seen him scratching. Regardless, after reading your article above and many others on mange, I'm going to reworm him with the same oral dose (1ml per 50 pounds of body weight) of Noromectin, tomorrow. I never give them dry food, so mixing the Noromectin with the food isn't an issue.

    I'm so happy I found your site!

    Thank you!

  2. Thank you so much i have been trying to find answers an u had em

  3. Awesome explanation, thanks very much :)

  4. Can I use dog wormer? And will the mites go on my dogs and cats? And our pig sleeps in our bed. Is the mites in our bed and will they stay? We have a rash on us now. How do we get them gone out of our bed?

    1. I am also interested in these questions and looking for answers that would be great

    2. The answer to the mites is yes they can i just happen to find out the hard way if you get them from your pig it is scabbies and you have to wrap your bed in plastic for 5 days and spray all furniture with lice spray and vacuum and put a cream on your skin and al kinds of stuff. not a easy thing to deal with at all. wash all bedding and so forth and keep it washed every day. and it is highly transferable to others.

    3. I ordered Ivomec and they sent me injectable. Can I give that orally instead?

    4. Yes that is what we use to give orally. You will need a needle and syringe to get it out of the bottle.

    5. Wow I'm so happy I found this site I am all off the above but on round two I believed it was there hair.

  5. Can I use dog wormer? And will the mites go on my dogs and cats? And our pig sleeps in our bed. Is the mites in our bed and will they stay? We have a rash on us now. How do we get them gone out of our bed?

  6. Thanks for the advice.I did not want to inject my pig Leroy with ivermectin again as it really upset him so i will now give it orally.The vet said it would not work but i now believe it will.Your advice is apprecciated.

  7. thanks for your advice

  8. took both my piggies to the vet, cause i was concerned about an itchey rash on the bigger one. i have noticed that they both itch a lot, but thought it was attributed to there very dry flaky skin. (i also learned to help the dry skin they should be given vitimin E everyday) the vet diagnosed it as mites and gave me some oral meds for both of them. 3 days after the first dose the little guy pooped out a huge worm. took it to the vet so she could have a look. witch i then learned the mite meds also act as a dewormer! so after finding out this new information i decided to find out what type of worm it was and if is transferable to humans. and fell apon this website. and found it very helpfull. thank you

  9. this sight also tought me that i should be doing this twice a year(vet failed to inform me of).... question tho is there anything i can do to my lawn to help pervent them from contracting it again?

  10. Wondering how long after we have treated with the Ivomec Pre-mix for Swine should it take for the pigs to be clear of the worms?

  11. If I was to look at using the dectomax injectable, can I use this as a pour on instead? Just wondering what the rate would be?

  12. Been dealing with mange on my Lola. I have found on several occasions that, giving ivermectin orally is not effective while injection works like a charm.

  13. If I were to use the Ivermectin Paste Wormer 1.87%, how much would I need to use on a 14 1/2 lb mini pig?

    1. We have never used the paste here as it is made for horses and the worms/mites horses get are different then our pigs. Thus the reason for different de-wormers. However, I did find where people that do use it double the dosage to what a horse takes. Someone found that putting in Twinkies seemed to work good for them. Personally I would stick with one made for pigs.

  14. Thank you for your good info. I gave my little pig the invermectinon a oraly but five minutes later she got sick and I'm not sure how much she absorbed. Can I give her the invermectinon pour on also? I'm worried about overdosing her.

  15. You can give the Ivermectin pour on just make sure to follow the directions for dosage. It is a very safe product and hard to overdose.

  16. I got a pick christmas eve for my daughter and it obviously had mites. I bathed the pig and yes slept with it and within a week we were broke out all over and the pig was scratching on everything. We have been treated and the pig has been given ivomec shot and a dip in peremthrin. how long before he stops itching? I put him out and want to bring him back in the house but am afraid

  17. He should stop itching in about a week. Remember to give the 2nd dose to kill the larvae that might hatch. You can also dust with DE food grade to help with the itching.

  18. I have a baby mini pot belly and we just got him about 2-3 weeks ago and all of a sudden this horrible rash came up on his stomach then it was all over and to me it looked like hives on a human, I am trying to find a vet near me who treats pigs, from everything I am reading it looks like it might be mange, I am wondering if it might be better for me to take him to the vet or treat it myself? I gave him a little Benadryl the last few days but it is just drying up and has a whitish crust but is worse, I'm so worried about him and I feel so bad because he is so itchy and miserable, I was thinking about taking him to the humane society but wasn't sure if they do pigs. Help.. My little Wilbur please

  19. I would take Wilbur to the vets office so that you know for sure what is going on with him. I would want to know if it is a rash or mites. The Benadryl will not do anything if it is mites. Please take him to the vets so he can be checked and treated correctly.

  20. Hi, I have an 11 week old mini pig. He has been o the vet and they gave him a first round of shots and plan to have him neutered within the next week. He has some discoloration on his testicles under his rear that is a brownish-orange. He also had a little the back of his neck. When I bathe him it washes off but I am wondering if this is the start of mange or just pheromones or something?

    1. Pig rust is what you're describing, you can Google it to get more information.

    Awesome. My Kunekune pigs will love you. They will happily eat their ivermectin vs a shot. They squeal at just the sight of a needle! hahaha

  22. How much would use of the 5mg pour on for a 8 week old

  23. Please follow the directions on the bag. It should give you a dosage, usually the dosage is by body weight.

  24. Hi. I have a 2wk old mini potbelly and she started scratching on everything. Her back is scaly and sometimes she gets like a red/orange color on her back from her head down. What should I use/or do?

    1. With one that young you should take her to the vet to be treated. I would want to make sure that she does have mites before treating for them.
