If you haven't de-wormed your W/C then it will have the propensity to pass any parasites to another snake, mostly through fecal matter.
A Vet would weigh you snake and probably use Panacur. It's an oral medicine and probably receive a second treatment 2 weeks later.
The second treatment can be done by you.
Most Vets. do the first in office and send the meds. home with you along with a syringe.
This has been my experience.
