Thank you guys for helping to identify.

Thank you for reply. One more thing to add: It's winter, outside is quite cold, but would it be possible for wasps to survive inside the house (to be precise, she's not even living in house, but in apartment on 6th floor of building).

Sorry, I didn't know where to open this topic, but can anyone tell me what is this? My sister found it in her house on her book. It looks like nest or larvae I think.
