There are 2 flies in my place right nnow adn I'm trying to figure out how to get rid of them. I've never seen this kind before--they're shaped like moths but clearly flies. In any case, they're annoying and only show themselves 1 or 2 at a time. Whatever's posted in this thread, I'll try it!
ETA: Duh. I did a quick search aaaaaand ta-da. They are called "moth flies."

They breed in drains, which would explain why they appeared around the time my tub started leaking. Now that it's been fixed, maybe one good spray will be enough to eradicate them from my apartment. *googling how to kill these suckers*
