Your c0ckp1t is not filthy until you see roaches walking around.
After the company which hired me in the 80s was bought out/merged, the then brilliant CEO (who lost his "golden parachute" due to "alleged" kickbacks from Airbus, while ordering the first A-320s in North America ['Wall Street Journal']) laid off lots of aircraft cleaners. After seeing roaches in the galley, and on the back of a captain's coat as he walked out, past incoming passengers....a crewmember called the local health department.
The local health department said that the aircraft would be kept cleaner or the operation would be in deep trouble.
The cleaners were quickly recalled.
Nowadays, roaches might be an endangered species because of "reality tv" programs. You should see which various repulsive insects/animal body parts a young Belgian lady chewed or swallowed on a Belgian show: "Unreal TV"?. As a simple comparison, the other things made the maggots look quite appetizing. The looks on her and the other lady's face were priceless. This was on American tv a few nights ago.
.Smaklijke eten.
