What do ant bites look like on humans?

If you come into any contact with these insects, you may get bitten, particularly if you're near an ant nest. But ant bites aren't usually serious – you may feel a nip and get a pink or red mark on your skin. Sometimes, a bite can hurt a lot, swell up and become an itchy rash.
