Bed bugs have made a major comeback in the U.S. and around the world. The public experienced a reprieve from the pests after World War II, due in part to the widespread use of DDT. The rebound in recent years was probably due to multiple factors, including less potent insecticides, global travel, and a loss of vigilance practiced in years past. Whatever the reasons, bed bugs are again part of everyday life, with infestations common in homes, apartments, hotels, dormitories, schools and shelters. With the recent increase in attention in recent years, especially as travelers come into contact with infestations of bed bugs, they also may be difficult to control without help from a pest control professional.
