Sarcoptic Mange in Pigs: Symptoms, Treatment & Control
- Sarcoptic mange is a contagious skin disease caused by the mite *Sarcoptes scabiei var. suis*.
- Common signs include intense itching, rubbing, red flaky skin, crusts, hair loss, and thickened skin around the ears, neck, and body.
- Your vet may diagnose it with skin scrapings, exam findings, and herd history. A negative scraping does not always rule it out.
- Treatment often involves injectable ivermectin or doramectin repeated in 10-14 days, plus cleaning bedding and treating exposed pigs at the same time.
- Humans and other animals can develop temporary itchy skin lesions after contact, so prompt control matters.
What Is Sarcoptic Mange in Pigs?
Sarcoptic mange is a skin infestation caused by the burrowing mite Sarcoptes scabiei var. suis. These mites tunnel into the outer layers of the skin, which triggers intense itching and inflammation. In pigs, the condition is often called swine scabies or sarcoptic mange.
This parasite spreads easily through close contact, shared housing, and contaminated bedding or equipment. In pet pigs and small backyard groups, one itchy pig can quickly become a group problem. In breeding herds, untreated adults can pass mites to piglets, which is why herd-level control is so important.
Signs can range from mild flaky skin to severe crusting, thickened skin, weight loss, and poor comfort. Some pigs show obvious itching, while others carry mites with subtler signs. Because of that, your vet may look at both the individual pig and the environment when deciding how likely mange is.
Sarcoptic mange is treatable, but it usually takes more than one step to control. Medication helps kill mites on the pig, while cleaning and treating exposed pigs helps reduce reinfestation.
Symptoms of Sarcoptic Mange in Pigs
Mange often starts with itch and skin irritation, then progresses to crusting and thicker skin if mites remain untreated. The ears are a classic early site, but lesions can spread to the neck, shoulders, and body. In some pigs, the skin becomes so uncomfortable that normal resting, eating, and social behavior change.
See your vet promptly if your pig is intensely itchy, losing weight, developing open sores, or if more than one pig in the group is affected. Also call your vet if people in the household develop itchy bumps after handling the pig, because sarcoptic mites can cause temporary skin irritation in humans.
What Causes Sarcoptic Mange in Pigs?
Sarcoptic mange is caused by infestation with the mite Sarcoptes scabiei var. suis. The mites spread mainly by direct pig-to-pig contact. That means newly acquired pigs, breeding animals, and pigs sharing close quarters are common sources of exposure.
Indirect spread can also happen through contaminated bedding, housing, or equipment, especially when cleaning between animals is limited. In group settings, leaving even one pig untreated can allow mites to cycle back through the whole group.
Stress, crowding, and delayed treatment can make outbreaks harder to control. Young pigs may become infested from untreated adults, and pigs with chronic skin irritation may be more likely to develop obvious lesions.
Not every flaky or crusty pig has mange. Your vet may also consider yeast dermatitis, nutritional skin disease such as parakeratosis, sunburn, lice, ringworm, or bacterial skin infection when working through the cause.
How Is Sarcoptic Mange in Pigs Diagnosed?
Your vet usually starts with a hands-on skin exam and a close look at where the lesions are located. History matters too. Itching that spreads through a group, ear crusting, rubbing, and recent contact with new pigs all raise suspicion.
A skin scraping is a common next step. During this test, your vet gently scrapes the skin surface and examines the sample under a microscope for mites, eggs, or mite debris. In pigs, ear scrapings or skin scrapings may be used. This test is helpful, but mites are not always easy to find, so a negative result does not completely rule mange out.
In larger herd settings, diagnosis may also include observation of clinical signs across the group, scratching scores, dermatitis scoring, and sometimes ELISA antibody testing as part of a broader control or eradication plan. Your vet may also recommend checking for other skin problems that can look similar.
Typical US cost ranges for diagnosis in 2025-2026 are often about $60-$120 for an exam, $25-$60 for skin scraping or microscopy, and more if sedation, farm-call travel, or additional testing is needed.

Questions to Ask Your Vet About Sarcoptic Mange in Pigs
Bring these questions to your vet appointment to get the most out of your visit.
- You can ask your vet whether my pig’s skin changes fit sarcoptic mange, yeast dermatitis, parakeratosis, or another condition.
- You can ask your vet which pigs in the group should be treated, even if only one is visibly itchy.
- You can ask your vet whether ivermectin, doramectin, lime sulfur, or another option makes the most sense for my pig’s age and housing.
- You can ask your vet how many treatments are needed and exactly when each dose should be given.
- You can ask your vet how to clean bedding, pens, and shared equipment to lower the chance of reinfestation.
- You can ask your vet what signs would suggest a secondary skin infection or another disease on top of mange.
- You can ask your vet how long it should take for itching and skin crusting to improve after treatment starts.
- You can ask your vet what quarantine steps to use before bringing a new pig into the home or herd.
How to Prevent Sarcoptic Mange in Pigs
Prevention starts with biosecurity. Any new pig should be quarantined before joining the household group or herd. During that time, your vet may recommend an exam, skin check, and preventive parasite treatment based on the pig’s history and risk.
Good housing hygiene also matters. Wash or replace bedding regularly, clean pens and shared equipment, and avoid moving pigs into spaces that may still be contaminated. In herd settings, treating all exposed pigs within the same time frame is one of the most important ways to stop the cycle.
Breeding animals need special attention because adults can pass mites to piglets. In production settings, control programs often focus on treating sows before farrowing and managing boars and replacement animals on a planned schedule. For pet pigs, routine wellness visits help your vet catch early skin changes before they become a larger problem.
If your pig develops itch, crusting, or hair loss, early veterinary care is the best prevention against a prolonged outbreak. Fast action protects your pig’s comfort and lowers the chance of spread to other pigs, other pets, and people.
