Hi again the vet told my sister they only lived on dogs and did not transfer to humans, thats a bit of a concern if they don’t as she has three young children and I’ve been visiting with my kids and doggy,is it true there’s no treatment as I said the vet said only a frost will kill them , I thought perhaps wrap some ice in a hankie and apply it to the areas that itch and maybe the ice will kill them, anythings worth a try, thanks again
