Cucarachas Disaperecen

So, just a quick little story while I have a little time. I have killed two cucarachas in my shower- on separate occasions. I hide them under the drain so that I don't have to deal with them until they are dried out, cause squishy bugs are yuckier then dry ones. So anyway, the next day when i go to deal with it, I pull up the drain cover and the cucarachas are gone. Now I have no clue how tey disappear. I know they were dead. Maybe their friends come for them. Or maybe they dry up and fall through the drain. However, they do it, it is a nice surprise because it makes it easier for me.
