Denver ranks high on list of worst bed bug cities

Bed bugs

Bed bug infestations are on the rise in the United States, and that means business is good for pest control companies.

Orkin says its bedbug business has gone up almost 33 percent compared to what it was in 2011.

The company attributes the growing bedbug problem to increased travel internationally and within the United States. Bed bugs have also developed better resistance to existing pesticides.

Orkin just released it’s ranking of cities in order of the number of bed bug treatments it performed from January to December 2012.

Chicago comes in at number one, followed by Detroit and Los Angeles.

Denver came in at number four in the country in 2012, with Cincinnati rounding out the top five cities. Colorado Springs/Pueblo came in at number 23 and Grand Junction/Montrose were at number 39.

“This list shows that bed bugs continue to be a problem throughout the U.S.,” Ron Harrison, Ph.D., Orkin entomologist and Technical Services Director said in a statement. “Based on the diversity of cities on the list, we all need to be very cautious when we travel — whether it is business or pleasure, or to visit family, friends or vacation.”

The Centers for Disease Control and Prevention says bed bugs do not transmit disease.

Bedbugs are the size and color of a flat apple seed. They’re found in all kinds of places including but not limited to mattresses, upholstery, suitcases, boxes, shoes, wallpaper and headboards.
