hmmm dont know anything about that stuff... what kind of wood fibers are they? If it's pine, fir, or cedar; i'd get it out asap! If your tank doesnt smell, I don't see why you want to clean it all out.
You may have to look to find where your snake defeciated... sometimes its hard to find. But its there (i hope... for your sake...) Give your snake upwards of 4-5 days to defeciate after it eats. I'd just look for it, get it out (i use a cat liter scoop for my aspen). Then change it clean it out every other month or so.
