Inside-Out Ear During Cria
-
Sometimes during the cria, or infancy, stage of growth, the ears will turn inside out because the newborn is premature. Leaving the ear like this will lead to problems with the ear later in the alpaca's development, so it is best to treat it immediately.
To ensure the ear remains folded properly, tape the base of the ear using breathable micro-pore tape, which will hold the ear properly in place. After the first day, the ear should be fine and the tape can be removed. Taping the ear as soon as the condition is recognized usually corrects the problem.
Mites
-
Mites are the most common threat to alpaca ears. They like the animal's soft tissue, choosing to burrow around the ears because of their warmth. Chorioptic mites are the most common species that reside around alpacas' ears. They cause itching and general discomfort, causing the alpaca to scratch the fur away and make the skin raw. Psoroptic mites cause serious ear mange in alpacas. A black waxy substance in the ears is a clear sign that mites are present.
Mite Treatment
-
The presence of mites should be diagnosed by a veterinarian, who will take a skin scraping. Medicine can be bought from the veterinarian, or owners can use a home remedy known as "witches' brew" involving mineral oil, Gentamycin, Ivermectin and dimethyl sulfoxide, or DMSO (see Resources). The mixture should be applied to the area for 15 days or more, depending on the seriousness of the infestation. These chemicals together work to remove just-hatched mites and make the living conditions less hospitable to adult mites.

Things About the Alpaca Ears
Alpacas are found in the Andean regions of South America and are perfectly adapted to high altitudes and cold climates. They have thick fur, large eyes and elongated ears. The locals depend on them for wool and food, caring for them in herds. Like most farmed animals, alpacas are susceptible to health problems, mainly with their ears; they are especially bothered by mites.
