Having lived in Manhattan where one must rage territorial battle for ownership of any living space, I reserve the right to revile the vermin in the language of my choosing...
That being said, "BLEICK!!!" does work. In a college arthro course, we had these giant Madagascar Hissing Cockroaches to play with. They were nearly 6" long. I remember it was very cool to let one walk up my arm and creep the other students out.
That was five years before I moved to Manhattan and had alll the in-laws take up residence in my apartment! Ewwww... (a well-earned ewwww....)
I'm not a lover. But your collection looks, mighty ...fine?
