ATLANTA — Chicago tops the 2014 Bed Bug Cities List for the third year in a row. The list, released by Orkin, ranks the cities by the number of bed bug treatments Orkin performed from January to December 2014. Bed bugs were in the news throughout 2014 in the Windy City, with reports of the blood-sucking insects on public transit and inside several downtown office buildings, as well as in police headquarters, a fire station, school, library and movie theater.

"Bed bugs are a serious issue across the country, and they're very difficult to control," said Orkin Entomologist and Technical Services Director Ron Harrison, Ph.D. "Bed bugs are not limited to any level of cleanliness or income, which means they can be found in any home or hotel. They're great hitchhikers, and people often bring them inside on their clothes or in their luggage."

Seven cities made double-digit jumps on Orkin's Bed Bug Cities List compared to 2013, including Omaha, Neb. (+16), Lexington, Ky. (+16), Sacramento, Calif. (+14), Grand Rapids, Mich. (+13), Buffalo, N.Y. (+12), Charleston, W.Va. (+11) and Louisville, Ky. (+10). Several cities also dropped significantly in the past year, including Syracuse, N.Y., San Diego, Miami, Greenville, S.C. and Atlanta. Four cities made the Bed Bug Cities List for the first time including Myrtle Beach, S.C., St. Louis, Bowling Green, Ky. and Ft. Wayne, Ind.
