Help!! Gnats! (Not sure if this is the proper place to post this)

🐾

I don’t know where these guys are coming from they’re literally everywhere. They’re tiny and black and their in my kitchen, hallway and living room!! They fly around my face when I’m on the computer, chill on the wall behind my computer, and they’re on the wall in my hallway and are always on my kitchen cabinets. They’re driving me insane, especially in my living room they will land in any drink I have and die and fly around my face 24/7. I’ve tried vinegar in a dish, peppermint oil in a dish and a vinegar water spray and nothing. Fly strips work, but they just keep coming back. I don’t have any rotten fruits anywhere and there’s never food in my living room unless we’re eating. And there’s never food in my hallway either so I’m just at a loss and going crazy. Does anyone have any advice?
