Munge in Alpacas
- Munge is the common herd term many alpaca pet parents use for mange, a contagious skin disease usually caused by mites such as Sarcoptes, Chorioptes, or Psoroptes.
- Typical signs include itching, crusting, scaling, hair loss, thickened skin, and rubbing. Sarcoptic mange is often the most severe and can spread quickly through a group.
- See your vet promptly if your alpaca has worsening skin lesions, weight loss, reduced appetite, or multiple affected herd mates. Early treatment is usually easier and more successful.
- Diagnosis usually involves a physical exam plus skin scrapings or other skin tests. In the US, a farm call, exam, and basic skin testing often fall around $150-$400, with treatment plans increasing total cost depending on herd size.
What Is Munge in Alpacas?
In alpacas, "munge" usually refers to mange, a skin disease caused by tiny mites. These mites live on or in the skin and can trigger intense itching, crusting, scaling, hair loss, and thickened skin. In camelids, the main mite groups linked with mange are Sarcoptes, Chorioptes, and Psoroptes. Different mites can cause different patterns of disease, and mixed infestations can happen.
Many pet parents first notice munge as rough, flaky skin on the face, ears, legs, or belly. Over time, the fleece may thin, the skin may become very crusty, and the alpaca may spend more time rubbing or scratching. Severe cases can interfere with comfort, body condition, and normal behavior.
Because mange is contagious and some mite species may spread through direct contact or shared equipment, it is best not to wait and see if it clears on its own. Your vet can help confirm whether mites are the cause and build a treatment plan that fits your alpaca, your herd, and your budget.
Symptoms of Munge in Alpacas
- Mild to intense itching or rubbing on fences, feeders, or shelter walls
- Crusting, scaling, or dandruff-like debris in the fleece
- Patchy hair or fiber loss, especially on the face, ears, legs, belly, or under the jaw
- Thickened, wrinkled, or rough skin in chronic cases
- Scabs around the ears or ear margins
- Restlessness, reduced comfort, or spending less time eating
- Weight loss or poor body condition in more advanced cases
- More than one alpaca in the herd developing similar skin lesions
Mild cases may start with subtle scaling or rubbing, but rapid spread, heavy crusting, severe itch, or weight loss are more concerning. Sarcoptic mange can become serious quickly, especially if several alpacas are affected.
See your vet soon if lesions are spreading, your alpaca seems uncomfortable, or herd mates are starting to show signs. See your vet immediately if your alpaca is weak, not eating well, losing weight, or has extensive skin damage.
What Causes Munge in Alpacas?
The most common cause of munge in alpacas is mite infestation. Published camelid references describe Sarcoptes scabiei as a major cause of severe mange, while Chorioptes is also very common in alpacas and may be the most frequently identified ectoparasite in some groups. Psoroptes can also affect alpacas, especially around the ears. These mites cause inflammation as they feed on or burrow into the skin.
Mites usually spread through direct contact between animals, but contaminated bedding, halters, feeders, and other shared items may also play a role. Crowding, stress, poor body condition, and delayed treatment can make outbreaks harder to control. In herd situations, one visibly affected alpaca may mean others are carrying mites too.
Not every itchy alpaca has munge. Ringworm, lice, nutritional problems, sun damage, bacterial skin infection, and allergic or inflammatory skin disease can look similar. That is why a hands-on exam matters before treatment starts.
How Is Munge in Alpacas Diagnosed?
Your vet will start with a full history and skin exam. Helpful details include when the problem started, whether itching is severe, which body areas are involved, whether new alpacas were introduced, and whether other herd mates are affected.
The most common test is a skin scraping, often taken from several sites. Deep scrapings are especially important when sarcoptic mange is suspected because those mites burrow into the skin. Your vet may also examine crusts, scabs, or hair under the microscope and may recommend fungal testing or other diagnostics if the lesions do not fit a straightforward mite pattern.
A negative scraping does not always rule mange out, especially early in the disease or when mite numbers are low. In some cases, your vet may make a working diagnosis based on the exam, herd history, lesion pattern, and response to treatment. If the case is severe or not improving, additional testing and herd-level review may be needed.

Questions to Ask Your Vet About Munge in Alpacas
Bring these questions to your vet appointment to get the most out of your visit.
- Which type of mite do you suspect, and what makes you think that?
- Do you recommend skin scrapings from more than one site or more than one alpaca?
- Should all exposed herd mates be treated, even if they are not showing signs yet?
- What cleaning steps matter most for bedding, feeders, halters, and shelter surfaces?
- What is the expected timeline for itching and skin healing to improve?
- What signs would mean the treatment is not working or that another skin disease may be involved?
- Are there any zoonotic concerns for people handling this alpaca?
- What follow-up schedule fits this case and our herd setup best?
How to Prevent Munge in Alpacas
Prevention starts with good herd biosecurity. Quarantine new alpacas before mixing them with the rest of the group, and ask your vet about checking any animal with itching, crusting, or hair loss before introduction. Early isolation of suspicious cases can reduce spread.
Regular hands-on skin checks are helpful, especially around the ears, face, legs, and belly where lesions may first appear. Clean and rotate shared equipment, replace heavily contaminated bedding, and avoid sharing halters or blankets between affected and unaffected animals until your vet says it is safe.
Good nutrition, low-stress handling, and prompt veterinary attention for early skin changes can make outbreaks easier to control. If one alpaca develops munge, think at the herd level, not only the individual. Your vet can help you decide whether monitoring, testing, or preventive treatment of contacts makes the most sense for your situation.
