These parents' young lady had visited a friend at Amherst University who had dealt with a bed bug problem recently.
The young lady came back home and started to get bites in her bedroom.
She decided to sleep downstairs on the couch, so that she would not get bitten anymore.
A word of caution: Moving to a different area in the house does not eliminate the problem, rather it may make things worse. The little buggers will go hunting for you or the nearest meal available.
Also, piles of clothes were strewn all over the room. I recommended they secure the clothes in a bag and put it in the drier at high heat for an hour.
