Bedbugs can be found in mattresses, furniture and clothing, and they feed off animal and human blood. Insect scientists say bedbugs are showing up on a scale not seen since before World War II.
High-traffic areas such as hotels, airplanes and cruise ships are especially prone to infestations.
Terminix recommends that travelers check headboards and mattresses for bedbugs and the dark blood spots they leave behind. Baggage should be stored far from the bed and clothing should be hung rather than placed in hotel drawers or left lying on hotel furniture.
After a trip, people should vacuum suitcases and wash clothes in hot water. (AP)
