How it's used

This reduplicated form adds a sense of triviality or annoyance, often used when referring to small pests collectively rather than a specific species. It carries a slightly informal, almost childish tone that emphasizes the nuisance factor of having multiple tiny insects crawling around. It is rarely used in formal or scientific contexts where specific names like 曱甴 or 螞蟻 are preferred.
