"gnat" 的定义和意义

What is a "gnat"?

A gnat is a small flying insect belonging to the family Culicidae. It is characterized by its slender body and long legs and is often found in damp or marshy areas. Gnats are known for their annoying habit of swarming around humans and animals, especially in the warmer months. They are attracted to moisture and can be a nuisance, as well as potential carriers of diseases. While most gnats are harmless, some species can bite and cause itching or allergic reactions. Controlling gnats often involves eliminating their breeding sites and using repellents or traps to keep them away.
