little moths keep coming into my apartment

I just moved and I keep finding these small moth-like bugs in my apartment. about 1 to 2 per night. I thought it was a baby cockroach at first and was spooked. I have no food in my apartment (I just moved in last week), I never really open the windows or my door, and I don’t see any visible gaps…how are they coming in, why, and how can I prevent them?
