Psoroptes sp. mites were isolated from two llamas (Lama glama), a 4-mo-old male and its dam, in Washington. Mites were restricted to the ears and were responsible for head-shaking and incoordination. Infestations were treated successfully with a subcutaneous injection of ivermectin at 0.2 mg/kg of body weight and with 2 drops of ivermectin diluted in saline given topically in each ear. This is the first known report of Psoroptes sp. in llamas in the United States.
