What Causes a Bedbug Infestation?
Bedbugs are found in temperate and tropical climates worldwide. They are most commonly found in living quarters where their host resides. Bedbugs generally hide in the seams and crevices of mattresses and box springs, bed frames, headboards, old furniture, and in spaces underneath baseboards or behind loose wallpaper. Clutter and disarray also provide additional hiding places for bedbugs. Bedbugs may be transported from one location to another via luggage, furniture, clothing, and used mattresses. Although they are often associated with unsanitary living conditions, bedbug infestations also occur in clean, well-maintained living quarters, including five-star hotels and resorts. Bedbug infestations have been increasingly reported in hotels, dormitories, homes, apartments, nursing homes, jails, and hospitals. There have been several cases in the U.S. involving litigation because of bedbug infestations.
Prior to World War II, bedbug infestations were common; however, after the widespread introduction of the use of the insecticide DDT in the mid-20th century, bedbug infestations became much less common. The recent resurgence in bedbug infestations worldwide is thought to be related to several different factors, including the increase in international travel, dense urban living conditions, insecticide resistance, and new, ineffective pest-control measures.
