There are several steps that can be taken to minimize the risk of infestation:
Carefully inspect or avoid second-hand furniture, mattresses and bedding
During hotel visits, do not place luggage on the bed or furniture until you have inspected the bedding, mattresses and headboards
When traveling, periodically inspect your luggage and bag
Encase your beds with bed bug proof encasements such as Protect-A-Bed bed encasements
