I just moved into my new apartment yesturday! Today I spent the whole day cleaning, and to my horror, I noticed a big scatter of little black/brown granules at the back of the cabinet under the bathroom sink.
I took a deep breath, sucked it up and wiped it clean. I did not pay close attention to what it actually was.
A few hours later, I noticed there were new granules. I picked one up and it was a bug.
I killed a few today. I hope it’s not a full scale infestation – I certainly haven’t seen enough (yet). Can someone ID this for me? I know it’s a crappy cell phone camera picture, but that’s all I have right now. They don’t seem to fly, and they are about the size of a sesame.

Thanks.
