Thanks for the heads up.
My guy used to love butter worms, wax worms and super worms (that's what they carry at the pet store), but now he's almost completely off them... silk worms too, actually, he won't touch those anymore... so he's just eating crickets right now (and even then with less gusto). Looks really healthy though so I'm not worried too much, I was just hoping there was something else I might try that would be readily available and cheap.
PArasites sound like bad news thouhg.
