It would be a good idea to treat them for parasites. You can call your local herp vet and most likely they will be able to set you up with something to use.
First you need their fecals tested and have them checked by a qualified herp vet. The vet will determine if they have parasites or worms and then he/she will prescribe medication. Most imports do cary something but because they are long term WC they may have already been treated. Just don't "assume" because we al know what that means.
