Bed bugs are a significant public health concern
Bed bugs can be a real threat to your physical and emotional well being. There has been increasing reports of bed bug infestations, primarily where there is poor housing and in low quality hotels, over the years. In order to determine if there has been any credibility to these reports researchers have decided to study the situation.
Researchers discovered statistically significant Cimex lectularius L. (bed bug) hotspots in Philadelphia, reported the Journal of Medical Entomology. The researchers analyzed a comprehensive telephone log of pest infestation reports in order to assess the spatial and temporal trends in bed bug reporting throughout Philadelphia, Pennsylvania.
Seasonal variations were found from December 2008 to May 2011, with a peak in August and reaching a nadir in February of each year. During this time period there was an increase in bed bug reports at a rate of 4.5 percent per month, or 69.45 percent per year. It is hoped that interventions based on seasonal trends may improve efforts to lower the recent increases in urban bed bug populations.
A new study from Penn Medicine epidemiologists, which investigated four years of bed bug reports to the city of Philadelphia, discovered that infestations have been increasing, These findings point to two possible peak times, in August and February, to strike and eliminate the bed bugs. Michael Z. Levy, PhD, who is an assistant professor in the Center for Clinical Epidemiology and Biostatistics at Penn, said, “There is surprisingly very little known about seasonal trends among bed bug populations.”
Dr. Levy worked on mapping the bed bug hotspots in Philadelphia with a goal of finding more effective ways to control them. He went on to say his research team discovered a steep and significant seasonal cycle in bed bug reporting. They suspected that bed bugs have different levels of mobility which depend on the season, and that their population size may change during the year.
