So I just moved into my new apt about a month ago and first week after cleaning found black dust in the corners of my kitchen drawers, wiped again and they came back in an hour… a few days later I found 3 larvae in the drawers!!
Called building’s exterminator and found the black dust still kept showing up… so we called exterminator again. 1 week went by, there are minimal black dust now in the corners of the cabinets.

And idk if I’m just paranoid but I found this (first two images) on a recently washed Steamer tray, it was stuck to the tray and then stuck onto the paper towel…. Note: we haven’t opened this drawer in a few days. Can someone tell me what this is? If it’s a concern? I’m thinking of calling an exterminator again…
