(n) An ootheca. A long term accumulation of cockroach egg sacks fecal mater and otherwise long dead roach body parts. Often found in dark hard-to-reach places especially in kitchens as in under the refrigerator or around cheap Chinese-made electronic items such as clocks.
There were quite a bit of roach casings from that last tenant we just evicted.
