Ypou are probably more likely to see bedbugs in crowded low income residences for the same reasons you might find them at an exclusive Manhattan hotel. Namely, differnt people traveling and using a common location transport the eggs and possibly adult insects which then take residence. Due to the nature of the insect and their resistance to insecticides the problem becomes apparent. It is as common among the exclusive as it is among the crowded dwellings of the poor.
