We have always had gnats in Central Texico, but you can actually see 'em and their bites aren't that bad. This year around here, there's a new kind of bitey flying thing that you really can't see, and their bites are worse. I'm assuming these are the no see ums everyone talks about, which have never been much of a thing here. They are actually one type of gnat, but there are many other types of gnats, which have traditionally been a lot more common around here.
Regardless, I dislike them way more than traditional gnats. I blame Florida.
