Can american cockroaches infest a house?

I LOVE my periplanetas!! They are considered a paradomestic pest not a true "I'm gonna ruin everything in the house" pest.

 
Reviving this thread... but with slightly different question... are Australian Roaches (Periplaneta australasiae) considered to be a species that can infest? I have a growing colony of them, and I found an adult out (I was horrified that it had escaped without my knowing) and now I am a bit concerned.

So, can Australians infest?

Also, are they more or less infestive than the Americans mentioned elsewhere on this thread?

Thanks.

There are australians that've been breeding for at least one generation in my room. They get into other roach containers to acquire moisture and steal food and seek shelter then they crawly around everywhere at night :(

 
I remember treating in the basement of a penitentiary in Oh that had Americans. It was 90 degrees year round, the humidity was unreal, puddles of water on the floor and the lights on 24/7. They hung out on the massive pillars that supported the floor above and would just run to the back side when you approached. You could spend hours spraying them directly and see the same amount next week and no dead bodies the following week. The temps and humidity must have degraded the chemical quickly because I assumed they ate the dead bodies.
