Is this a drain fly?
It's a fuzzy picture, but it appears to be the type of moth that is the adult form of a "meal worm", called a "meal moth" or "Indian mealmoth". You likely have some opened bag of wheat or corn meal somewhere that you rarely use and it had meal worm eggs in it, which are almost microscopic and nearly impossible to remove in processing. Those eggs hatched into larvae, the "worm" stage, now those larvae have grown up and into their adult moth phase, where they only live a few days as they look to mate and make more babies.
