She may not be wild-caught, actually, may just have had bad husbandry before you got her. Or it may be an outside source; a few days ago I found mites (MITES!!!!) on my previously clean-as-a-whistle girls, which turned out came from my roomate's bird and are completely harmless to my herps.
I wouldn't use Panacur; horses have very different tummy structures and metabolisms than snakes, and it'd be easy to overdose a snake using it. I wouldn't worm the snake unless you had a reason to, since it can really stress their system otherwise. Your vet should be able to tell you whether or not treatment is a good idea. Thankfully, it's one of the cheaper types of herp sicknesses, if caught early.
Which snake is this, the BP or the King?
