My family had a bout of scabies (a little embarrassing) that they gave to me. Because you can’t get medicine for it over-the-counter, I researched what the ingredient is that kills them. I found it to be permethrin, which is a synthetic chemical created to kill scabies and lice. They do not sell anything over the counter in a strong enough concentration to kill scabies. But guess what?…they do for dogs!...
