how do you do this
is it just a case on sprinkling some stuff on its food??
Also the head line should read Worming a beardie LOL

Nope! nowhere near that straight forward. you need to takea poo sample to your vet ( the beardies, not yours!) and ask for a fecal screening. tell them what type of animal it is and they will tell you what type (if any) parasites it has. MUCH better to let an expert deal with it, as it often involves forcing the mouth open and you need to get a vet to show you how to do it. Also beardies can have unusually high levels of coccidia, which can be fatal to other species. some people think this is normal for beardies, others tryto get rid of them. either way, if your beardy is happy, healthy and eating well, its just a routine check up. but well done for deciding to get it addressed. alot of reptile ownerasdont bother chacking for parasites and then wonder why there animal dies.

have a look at this thread, goes a little more in depth Worming
