Suggestion: Shave the affected portions of the body, but Nix or Kwell should take care of the problem. You can try bathing with dog shampoo for fleas. Someone told me that works for head lice. It has Lindane in it, and that's what Kwell has in it also. If you did not repeat treatment in 7 days, it's possible that new eggs hatched. So, you can try retreating the body and do it again in 7 days, or you can shave, or use dog shampoo daily for 7 days. Good luck. And next time know the possibilities. Scabies is the least of it.
