I have a very good exotics vet that has treated 2 of my snakes over the years and I always talk to him first. I had brought this up to him about a year ago asking if he knew any breeders that treated with this at home. I only have 2 CH balls in my collection which were both treated, and one imported SD retic which was treated 5 years ago. What worries me is that live or pre-killed food can re-infest snakes. Its good to have this info in case I ever discover one of my animals has parasites and would like to avoid the extra vet fees.
