Patients 11-17 years of age will read and sign an Independent Review Board (IRB)-approved assent form and patients 6-10 years of age will provide verbal assent. Patients 2-5 years of age will be exempt from providing assent based on the child's comprehension and cognitive skills.
4. Clinical diagnosis of active scabies by presence of a burrow and/or typical scabietic lesions at the classic sites of infestation.
5. Parasitological confirmation of clinical diagnosis with demonstration under light microscope of mites and/or their products (larvae, eggs or fecal material).
6. Symptom score of 2 or 3 on a 4-point rating scale of 0-3 for nocturnal itching/pruritus.
7. Ability to apply or have study product applied as directed. If patient is a child, then parent/guardian will apply study product to him/her.

Exclusion Criteria

Patients with severe cutaneous bacterial or fungal infections requiring therapy (including systemic and topical antibiotics) or coexisting dermatological disorder that could interfere with the diagnosis and subsequent monitoring of scabies) or heavily crusted with lesions consistent with Norwegian scabies.
7. Patients with an underlying immunodeficient state (including prolonged treatment with corticosteroids), immunosuppressive disorders requiring therapy, severe systemic disease and history of HIV infection.
8. Any condition, medical, psychological, or social, that, in the Investigator's opinion, would interfere with participation in the study.

Primary Outcome Measures

Name	Time	Method
Number of Patients in Each Treatment Group With Therapeutic Cure (Parasitological Cure Plus Clinical Cure) of Scabies	Day 28 ± 4	Parasitological cure is defined as failure to demonstrate microscopically the presence of scabies infestation (i.e., no living mites, no viable mite eggs, and no mite fecal matter present).; Clinical cure is defined as visual evidence of absence of new lesions and healing of original lesions, regardless the presence of post-scabietic nodules (i.e., post-scabietic nodules need not be considered as new lesions or persistence of old lesions).
