This entered into our flat yesterday evening and Mily has not been able to relax since .... she got a genuine fear of these creepy crawlies!!!
However I found it this morning and killed it (photographic evidence here) so things are back to normal in the house again ;)
Some Copy and Paste info below from a website regarding facts on this bug.
They can survive ten minutes in a vacuum, levels of radiation that would kill a human in one second, prolonged submersion in water, being at ground zero of an M60 cherry bomb - though shoe heels bearing down, as well as being inside active microwave ovens, will kill them.
A cockroach can live without a head for a week, after which lack of water intake will cause it to die. Not because it's lack of head but lack of water. It can go for a month without food, but only a week, as I said, without water.
A female cockroach can gain enough sperm from a single mating to reproduce over her entire life span, up to one year. A single female cockroach that had mated just that once can have 90,000 offspring within three months
