what people refer to as cockroaches in florida, aren't like the cockroaches that you encounter in New York or Chicago or any northern US urban area....the florida "cockroaches" (palmetto bugs) aren't really related to sanitation.....i'm assuming this is what you saw....they are very large bugs, that usually require at least a bazooka to kill....we have them where we live....they are native to very hot climates....(and the ones where i live fly as well....

.....nothing like lying in bed and suddenly have one of those babies land on your shoulder

they're so big here, you could saddle up and ride them....)
i'm hoping this is what you saw.....if it was a real cockroach cockroach (what are often referred to in the states as a german cockroach, as opposed to the palmetto bug, sometimes called the american cockroach), then that's a good deal less appetizing.....of course, palmetto bugs aren't very appetizing either, but if you live in a hot climate you get used to them (ok...so maybe not used to them, but they freak you out a bit less over time....ok...so maybe they keep freaking you out, but you get pretty good at murdering them.....but in the long run, they'll all be alive and we'll be long dead.....)
