Diligence and use of the pesticide DDT in the 1950s and broadbased pesticides also resulted in a dramatic reduction of bedbugs overall in the United States, though significant reservoirs of bed bug infestation persisted

through this period, particularly in inner-city areas.  During the bed bug recession period of the 1950s, infestations were

through this period, particularly in inner-city areas.  During the bed bug recession period of the 1950s, infestations were

mainly found in homeless shelters, and prisons, while during in the period 1967-73, about 61% of infestations were found in domestic residential property, while about 25% were in institutional settings<ref> [http://www.google.com/url?sa=t&source=web&cd=15&ved=0CI8BEBYwDg&url=http%3A%2F%2Fwww.icup.org.uk%2Freports%255CICUP911.pdf&ei=_7fkTMOcM4X7lwfpgvC1Cw&usg=AFQjCNHAv-kTckL-i94tT9QVwttxl-L2YQ&sig2=nWe_LzSDoRelL73t_I6ljg  ''Bed bugs (Hemiptera: Cimicidae): An evidence-based analysis of the current situation,'' Proceedings of the Sixth International Conference on Urban Pests], p. 9, 2008</ref></ref><ref>[http://www.birc.org/MarApril2007.pdf ''Bed Bugs bounce back'', IPM Practitioner], March/April 2007</ref<ref>>http://www.faqs.org/periodicals/201006/2054573271.html</ref>

The current resurgence of bedbug infestations appears to have started almost synchronously in the late 1990’s in Europe, the United States, and in Australia. 2007 Data from a survey of pest control companies in the latter country indicated a 4500% increase over seven years.<ref>''Bed bugs (Hemiptera: Cimicidae): An evidence-based analysis of the current situation,'' Proceedings of the Sixth International Conference on Urban Pests, p. 1, 2008</ref><ref>Doggett S.L. and R.C.
