Do gnats live in human hair?

Yes! Gnats do bite. The bites usually itch a lot and can be painful! They bites are very aggravating! Some usually have a bit of blood at the top. When you are bitten, you may not know it but soon it'll start to swell up. If you have a bite, clean it because of the gnat's bacteria it carries. Then, buy like anti- itch cream to make it stop and the bites should clear up!
