Symptoms are itching and scratching, a gradual increase in miliary lesions or generalized dandruff, hair loss, and red papules on the head, neck and back. Walking dandruff is also a pathogen for humans. It won't reproduce on them, but the bites will cause itchy pustules. The lesions will usually go away after ridding the environment of the parasites. Once walking dandruff has been diagnosed on a cat or human in the household, all animals and the entire environment should be treated.
Cats can be asymptomatic carriers and the environment is probably contaminated.
The environment should be sprayed with an insecticide. Information provided by K-State Media Relations and Marketing may be reproduced without permission.
