Cockroaches as pets

[shaydeesnail]

I've seen a few sites selling cockroaches- and they seem quite interesting, but I've grown up being told that cockroaches are dirty disease ridden things. Do they present any danger when kept as pets?
If a pet cockroach or two escaped is it likely that they would infest the house? I've never heard of anyone I know having a roach infestation, I think it must be a lot less of a problem in the UK than it is in the USA.
So... if I'm completely misinformed please sort me out!

Hi!

One of my friend is keeping a lot of cockroaches from few years. She is a girl and she loves these lovely pets. Cockroaches are not so dirty animals, easy to keeping. I don't know that is problem to keep roaches in the USA or UK, but in Hungary isn't problem to keep it.
