Chorioptic Mange in Alpacas

Quick Answer
  • Chorioptic mange is a skin mite infestation caused by Chorioptes mites that often affects the feet, lower legs, tail base, and other fiber-poor areas in alpacas.
  • Many alpacas become itchy, stamp their feet, chew at affected skin, or develop scaling, crusting, and patchy hair loss.
  • Diagnosis usually involves a physical exam plus superficial skin scrapings, tape prep, or sometimes skin biopsy because mites can be hard to find.
  • Treatment often needs repeated therapy over several weeks and may include clipping, topical mite control, and injectable antiparasitic medication chosen by your vet.
  • Typical US cost range for diagnosis and treatment is about $150-$600 per alpaca for straightforward cases, with herd treatment or repeat visits increasing the total.
Estimated cost: $150–$600

What Is Chorioptic Mange in Alpacas?

Chorioptic mange is a contagious skin disease caused by Chorioptes mites. These mites live on the surface of the skin rather than burrowing deeply. In alpacas, they often affect the lower legs and feet first, but they can also involve the tail base, perineal area, belly, and other places with thinner fiber coverage.

This condition is usually more irritating than life-threatening, but it can become a major welfare problem when itching is intense or when skin damage builds up over time. Alpacas may rub, bite, or stomp because the mites trigger inflammation and itch. Repeated self-trauma can lead to thickened skin, crusting, broken fiber, and secondary bacterial infection.

Chorioptic mange can be frustrating because it may smolder in a herd. Some alpacas show obvious signs, while others carry mites with only mild scaling. That means one itchy alpaca may be the visible part of a larger herd problem. Early veterinary guidance helps limit spread and makes treatment planning more practical.

Symptoms of Chorioptic Mange in Alpacas

  • Itching or rubbing, especially around the feet and lower legs
  • Foot stamping, restlessness, or frequent nibbling at the skin
  • Dry scaling or flaky skin on the pasterns, fetlocks, tail base, or belly
  • Crusting, thickened skin, or scabby plaques
  • Patchy hair or fiber loss in irritated areas
  • Raw skin, bleeding, or signs of secondary infection from self-trauma
  • Weight loss, poor body condition, or reduced comfort in severe chronic cases

Mild cases may look like dry skin at first, especially on the lower legs. The bigger concern is progression. If your alpaca is very itchy, damaging the skin, or if several herd mates are showing similar signs, it is time to involve your vet. See your vet sooner if there is swelling, foul odor, discharge, lameness, or rapid spread, because those signs can point to secondary infection or another skin disease that needs a different plan.

What Causes Chorioptic Mange in Alpacas?

Chorioptic mange is caused by infestation with Chorioptes mites. These mites spread mainly through direct contact between alpacas, but contaminated housing, shared handling areas, and grooming equipment may also help move mites through a herd. Crowding and close winter housing can make transmission easier.

Some alpacas seem more likely to show clinical signs than others. Heavy fiber around the legs, chronic skin irritation, stress, poor body condition, and delayed treatment can all make the problem more noticeable. In many herds, a few alpacas become very itchy while others carry mites with only subtle scaling.

There are also look-alike conditions. Zinc-responsive dermatosis, lice, fungal disease, bacterial skin infection, and other mange mites can resemble chorioptic mange. That is why a visual exam alone is not enough to confirm the cause. Your vet will help sort out whether mites are the main problem or part of a larger skin issue.

How Is Chorioptic Mange in Alpacas Diagnosed?

Diagnosis starts with a hands-on skin exam and a discussion of the herd history. Your vet will look at where the lesions are located, how itchy the alpaca is, whether other animals are affected, and whether the problem is seasonal or recurring. Chorioptic mange often targets the lower limbs and other sparsely fibered areas, which can be a helpful clue.

Testing usually includes superficial skin scrapings from active lesions. Because mites can be hard to find in camelids, your vet may take samples from several sites and may repeat testing if the first scrape is negative. Tape prep, hair and crust examination, and cytology may also be used to look for mites, eggs, or secondary infection.

In some alpacas, especially when lesions are chronic or the diagnosis is unclear, skin biopsy may be recommended. This is particularly useful when your vet is trying to distinguish mange from zinc deficiency, immune-mediated skin disease, or other causes of hyperkeratosis and scaling. A response to treatment can support the diagnosis, but it should not replace proper testing when the picture is uncertain.

Treatment Options for Chorioptic Mange in Alpacas

Spectrum of Care means you have options. Here are treatment tiers at different price points.

Budget-Conscious Care

$150–$300
Best for: Mild to moderate cases in otherwise stable alpacas when the goal is to confirm mites and start practical treatment with careful monitoring.
  • Farm-call or clinic exam
  • Targeted superficial skin scrapings from affected areas
  • Clipping fiber around lesions when needed
  • Topical therapy selected by your vet for lower legs and crusted areas
  • Basic herd-management advice, including isolation of visibly affected alpacas and cleaning shared equipment
Expected outcome: Often good if lesions are limited and treatment is repeated exactly as directed. Improvement in itch may come before the skin looks normal.
Consider: Lower upfront cost, but relapse is more likely if herd mates are not assessed, if crusts are not managed, or if follow-up is skipped.
Most Common

Recommended Standard Treatment

$300–$600
Best for: Most confirmed or strongly suspected chorioptic mange cases, especially when itching is significant or more than one alpaca is affected.
  • Complete veterinary exam and repeat skin scrapings as needed
  • Combination treatment plan using topical therapy plus systemic antiparasitic medication chosen by your vet
  • Treatment repeated every 10-21 days based on response and product used
  • Cytology or culture if secondary bacterial infection is suspected
  • Herd-level plan for exposed alpacas, environmental hygiene, and recheck visit
Expected outcome: Good in many cases, but treatment may need several rounds. Chronic cases can take weeks to months to fully settle, especially if the herd is reinfecting itself.
Consider: More complete and more likely to control the problem, but requires repeat handling, medication costs, and herd coordination.

Advanced / Critical Care

$600–$1,500
Best for: Severe, chronic, refractory, or herd-wide cases, and alpacas with marked skin damage, weight loss, or uncertain diagnosis.
  • Expanded dermatology workup with multiple scrapings, skin biopsy, and lab testing for look-alike diseases
  • Intensive treatment for severe hyperkeratosis, deep crusting, or secondary infection
  • Pain control, wound care, and prescription antimicrobials when indicated by your vet
  • Hospitalization or close outpatient follow-up for debilitated alpacas
  • Whole-herd outbreak planning, biosecurity review, and repeated reassessment
Expected outcome: Fair to good, depending on chronicity, skin damage, and whether all affected herd mates can be treated effectively.
Consider: Highest cost and labor commitment, but useful when first-line treatment has failed or when another skin disorder may be present.

Questions to Ask Your Vet About Chorioptic Mange in Alpacas

Bring these questions to your vet appointment to get the most out of your visit.

  1. Does this look most consistent with chorioptic mange, or should we also test for zinc deficiency, lice, fungus, or another skin disease?
  2. Which skin tests do you recommend first, and how often do negative scrapings still happen with camelid mites?
  3. Should we treat only this alpaca, or do exposed herd mates need treatment too?
  4. What topical and injectable options fit this case, and how many repeat treatments are usually needed?
  5. Do we need to clip fiber or soften crusts before treatment for better results?
  6. Are there signs of secondary bacterial infection that need separate treatment?
  7. What cleaning or biosecurity steps matter most for pens, chutes, and shared equipment?
  8. When should we schedule a recheck or repeat skin scraping to confirm the mites are controlled?

How to Prevent Chorioptic Mange in Alpacas

Prevention starts with herd management. New alpacas should be quarantined before joining the main group, and any alpaca with itching, crusting, or unexplained hair loss should be examined promptly. Early action matters because mildly affected animals can still help maintain mites in the herd.

Good skin and fiber care also help. Keep housing dry, reduce crowding when possible, and clean or disinfect shared grooming and handling equipment between animals. Regular hands-on checks of the feet, pasterns, tail base, and belly can catch subtle scaling before it becomes a larger problem.

Work with your vet on a parasite-control plan that fits your farm rather than relying on routine blanket treatment. Merck notes that monthly ivermectin prevention has contributed to resistance concerns in camelids. A targeted plan based on exam findings, testing, season, and herd history is usually the more thoughtful approach.

If your herd has had mange before, ask your vet what a relapse-monitoring plan should look like. That may include checking high-risk animals more often, treating exposed herd mates when appropriate, and re-evaluating any alpaca whose skin does not improve as expected.
