Don't let the bed bugs bite!Most householders of this generation have never seen a bed bug; until recently, they also were a rarity among pest control professionals.

Bed bug infestations were common in the United States before World War II, but with improvements in hygiene, and especially the widespread use of DDT during the 1940s and ‘50s, the bugs all but vanished. The pests remained fairly prevalent, however, in other regions of the world including Asia, Africa, and Eastern Europe.

In recent years, bed bugs have also made a comeback in the U.S. They are increasingly being encountered in homes, apartments, hotels, motels, health care facilities, dormitories, shelters, schools, and modes of transport. Other places where bed bugs sometimes appear include movie theaters, laundries/dry cleaners, furniture rental outlets and office buildings.

Immigration and international travel have undoubtedly contributed to the resurgence of bed bugs in the U.S. Changes in modern pest control practice — and less effective bed bug pesticides — are other factors suspected for the recurrence.
