DETROIT (WKZO) -- Travelers should make sure to check the sheets when they visit Detroit, but especially so in Chicago.  According to the pest control company Orkin, the Windy City led the nation in reports of bed bugs last year.

Orkin says they increased their overall bed bug business by 33-percent.  Among the other cities on the list are Los Angeles, Denver, and Cincinnati.  The nation's largest city, New York City, landed at number ten on the list.

Ron Harrison, a technical services director for Orkin, says that given the diversity of the cities that made the list, travelers should be "very cautious" when they hit the road.  He adds that people need to remain vigilant against bed bugs wherever they are.
