"Gnats: Tiny Pests or Harmless Buzzers?"
While not all gnats have the ability to bite, some species of gnats, such as sand flies or black flies, can bite and leave itchy bug bites. Biting gnats are usually small, have two wings, and six legs. To prevent bug bites, it is recommended to use insect repellent, wear protective clothing, and avoid areas where these insects are commonly found, such as ponds, streams, and swamps. Most gnats, however, are not capable of biting humans.
