    Cheyletiella, or walking dandruff, is a contagious acarid which is carnivorous when young and breeds rapidly.

    Cheyletiellids are not very host specific and often affect humans.

  • Cheyletiellosis mainly affects young animals but can also affect adults.

    Acarids cause skin irritation which results in a pruritus of varying intensity and scaling of the skin which can be quite extensive.

    Lesions generally appear on the back.

  • Application of an acaricide, generally one treatment per week for 3 weeks with proprietary drugs which do not remain on the skin. A single application may suffice for formulations with persistent topical action.

    Prevention: insecticide-acaricide treatment of any new animals added to a household. When cheyletellosis appears among the group, depopulation and disinfection of the premises and treatment of carnivores of all ages are necessary. Adults often become healthy carriers or animals with few clinical signs.

Learn more about parasites

The threat of arthropod parasites for human and animal health is increasingly recognized world wide. The hazard of these insects or acarids is linked to both the direct lesions

they generate as well as their ability to transmit diseases.
