Today I found there are some white thing among the moss in my nepenthes's pot. Pics are here:    What's this? Is it a sign of some pest? If so, how to kill the pest? Thanks. |

My best guess is a form of mold or fungus.
I would rinse the media thoroughly and use neem or some other fungicide.
If that doesn't work after a few days change potting media.
What kind/how valuable is the Nep?

it certainly looks like a fungus of some kind. It should not harm the plant, but should be treated with a fungicide after manual removal.
Start looking at what would have caused it though, because if you put it in the same conditions, the fungus will invariably return.
Increase light, circulation and get lots of fresh air in to your chamber.

Well its probably a no but keep in mind spider-mites make webs above the soil.

This is true, ieatflies. But, if that much webbing were present in a spider mite attack, the plant would already be a gonner by this time, and you would see a multitude of tiny little spiders running around. Spider mites make a web that is instantly recognizable as Arachnid in origin. Fungus looks more like brand new cotton wool.

Eh! Its eating your Sphagnum! This is a fungus type thing, but you can think about it like it is a weed... It lives at the soil surface and you can easily remove it by hand. Since it looks like it has infected the Sphagnum, remove it and replace with fresh moss if you have it. This thing/weed will stick around unless all pieces are removed which can be a little difficult to achieve.
Not sure what chemicals work on it since it is easy enough to scrape it off the soil surface, wipe the pot clean near the soil line and add a layer of fresh soil. I've noticed if you burying some small bits of the white fuzzy in fresh soil they will die, so it does seem to need light to live...

fungus. dip the end of a q-tip in H2O2 (hydrogen Peroxide) and apply where the mold is.
