A single gnat has been bothering me for two weeks.

Obviously more than one, but only ever one at a time.

A was away for about a week and accidentally left some dished in my sink, when I came back there were a ton of gnats everywhere in my kitchen. I have since cleaned up, gotten rid of food, and put up traps, and most of them are gone.

However, across the house is my office. In my office, there has been one single gnat attempting to fly into my ears, mouth, eyes, etc. I spend a lot of time in my office so it has genuinely been driving me insane. I have sprayed this gnat with raid so many times and it always gets up and flies away. Everytime I kill it, another one takes its place.

I've put up a fly trap in here, but they don't go to it. There's no food in here, and at this point I don't know how to get rid of it. I'm going to light this room on fire if it persists because I can't get anything done with a gnat flying into my eyes every 10 minutes.
