Animals may maintain infestation for a long period of time without treatment.
Physical cleaning of surfaces should remove mites
Nonviable eggs, empty casings and mite parts can remain on coat for months post treatment
At the least, prior to the introduction of new animals.
Prevention and Control
Pathogen exclusion, quarantine and testing, and control by effective treatment methods and periodic monitoring is important
An Avermectin class drug in treatment has powerful broad-spectrum antiparasitic activity against most endo- and ectoparasites
Rederivation is an option
