If you have the scope with the removable secondary just take it out and point the scope down. I would get it done? before he starts doing his business.

I recentely attached an old Crayford focuser to my C-8, Last night when
setting up I noticed a cockroach crawling over the inside of the
corrector plate. Anyone have any ideas on how to extract, kill, remove
the cockroach I have some gel-bait based on boric acid but I'm not sure
it's a good idea to use the near coated optics. Should I I remove the
corrector and clean the corrector and mirror as a precaution?
