It is harmless for the terrapin to climb into the room. Eupolyphaga sinensis is neither a pest nor a beneficial insect. They don't bite people, and they don't parasitize people's physical appearance. However, the terrapin will affect the indoor environment and may make people feel uncomfortable. If terrapin is found crawling into the room, some measures can be taken to deal with it, such as spraying insecticide or cleaning the room.
