Knemidokoptes (Scaly Face Mites)

Knemidokoptes (more commonly known as scaly face or scaly leg mites) usually affect birds with compromised immune systems, as well as young birds. In some cases, the mites can remain dormant within a flock, with symptoms only appearing when a bird’s immune system becomes weakened.

The most common symptom are honeycomb patterned lesions that generally begins on the face and legs but can spread across the entire body. In severe cases, the mites can permanently damage the skin, feather follicles, and even alter the shape of the beak.

Birds showing lesions should be treated individually until symptoms resolve, while the rest of the flock should receive preventative treatment at least once.

Common treatments include ivermectin or moxidectin, which may be administered topically, orally, or via drinking water. Moxidectin is generally considered more stable in water, although water-based treatments can still result in inconsistent dosing between birds.

In the clinic, we have both treatment options available and can help guide you on the best approach for your flock. Although these medications are available over the counter, we strongly recommend having an avian veterinarian examine the lesions before starting treatment. In the past, we have seen birds that were suspected to have Knemidokoptes mites but were actually suffering from skin infections or simply had food debris stuck to their feathers.

It is also important to have your bird assessed by a veterinarian because healthy birds are often able to resist severe mite infestations. When a bird develops significant scaly mite lesions, it can sometimes indicate that there may be an underlying health issue affecting its immune system or overall condition.
