Hmm.
Asymptomatic pinworms are not necessarily worth treating (example source, but pretty common knowledge). A high level, though, can indicate poor husbandry (pinworms have a direct life cycle, and will build up if the animal is reingesting feces either directly or through feeders). At any rate, a dose of Panacur is like $15 at a vet.
Nationwide makes you call for a quote, but the website says that exotic plans for illness care "generally starts at less than $21/mo." (Note that their dog and cat policies are available only in 30% and 50% deductible options; not sure for reptiles. Also, "Wellness coverage is not available for exotic pets at this time.").
Anyway, say it is $20 a month and covers all illness-related care. If a beardie lives ten years, that's $2,400. It would be an unusual bearded dragon that would require $2,400 in illness-related medical care. Much more financially prudent would be to put $20 a month in a mason jar and keep the beardie healthy, and then when the beardie dies healthy at a ripe old age you celebrate its life with a Caribbean cruise. Get another bearded dragon now so you can take a friend on the cruise.![]()
