I do *not* inject it, I give it orally. Have used the both the injectable orally and the horse paste orally. It does not have to touch lice to kill them, I guarantee this.I know that @casportpony injects but I have read that biting lice are not sucking lice so I don't know how an injected treatment is going to kill a bug that is not sucking the chemical into itself. If you read the photo I posted it does say PO or IM...
