Yeah I live in Maine so my climate is a little different, I've had three male roaches escape and found one in an empty critter carrier that had some cricket food in it, and the other two were found drowned in the toilet and the bathtub. If any of them do escape they will go where it is warm and wet so typically to any heat source in the room or the nearest bathroom in the case of an escape, but overall they will not infest a house unless you live in a very tropic climate(ex. Florida, which is why it's the only state they are illegal in)
