Entomology (Study of Bugs)/What is this small brown teardrop shaped bug?

I saw this bug on the floor of my bedroom in my small apartment at night. I've seen them before around and just killed them not thinking much of it, but I decided to catch this one instead and see what they are, and after searching on the internet I thought it was either a German or Brown-banded Cockroach, however it looks like the immature stage and I've never seen one that looks like the adult stages of either of these. I keep my apartment clean, not much clutter. I would say the bug is less than a centimeter? It crawled quickly and stopped suddenly, like a roach.


Yep, that's a roach nymph, probably either a German or Brown-banded as you suspect (hard to tell from just the one image).

Cockroaches can hitchhike on and in your belongings (I brought one home in a briefcase once), and migrate between apartments.  So, if your neighbor is a slob, then....

I might casually ask around if other tenants have seen roaches.  If so, then the building might need a pest control service.  Otherwise, consider homemade baits to take care of the ones that find their way into your own apartment.

Good luck!
