My first Garter!

Not if it's done at home. Some Vets will give the medicine if you have the snake weighed and just request the medicine.
Others will want to do a fecal float and administer the medicines in office. This can be expensive.
I'm fortunate to have a Vet. that will just give the meds. I request.
Even with that my yearly Vet. bill is high.

Exactly. For about $8 I got enough meds to treat for tapeworms and a wide variety of other internal parasites, for at least 20 snakes.

What you're paying for at the vet is lab work to confirm the presence of parasites, and an overall physical exam to see if the snake is in good enough health to handle the treatment.

I just assess their overall health myself, time the treatment right, and treat them as if they have the parasites, even if they don't. If they're wild, chances are they do anyway. Haven't lost any snakes doing that so far but I do notice a big change in WC snakes after treatment, especially those coming from populations known for high parasite load. They put on weight easier, and their appetite is better, and they just seem stronger and more vigorous afterward.

They just seem to do much better long term in captivity after being treated for worms.
