Big thanks to Jacob Conwell and taylor_itkin does not match any existing user name for reading this over in chat, and also all the people who posted in the discussion page for SCP-723-J with suggestions for the rest of the -ad Roach family, and pretty much everyone in chat who joked with me about said -ad Roach family. Thanks to all of that, this page now exists, as does this: http://www.scp-wiki.net/kiryu-labs-roach-wrangling-log
In all honesty, yes, this is silly. I wrote this a few months ago when it occurred to me that there wasn't a lot of stuff on the mainsite explaining how/why joke SCPs exist in-universe (if they do). My headcanon is that in-universe, researchers write those things up for fun, and so each lab/department has their own set of inside jokes because according to my research that's how nerds make friends.
ETA: all images are CC-compliant since I took them with my phone. I saw a couple roaches last summer.
Happy New Year everyone.
