MEMPHIS, Tenn. -

Detroit ranks No. 5 on the latest annual list of Most Bedbug-Infested Cities by Terminix.

The list was created by compiling data from the 300 Terminix branches across the country. The company created the ranking by evaluating service calls from customers, as well as confirmed cases by service professionals.

Philadelphia took the top spot from New York City, which held the title for two years.

The 2012 ranking proves bedbugs continue to be a problem across the country, with five cities - Cleveland, Houston, Indianapolis, Miami and New Haven - joining the top 15 this year. Other cities, such as Columbus, Dallas, Philadelphia, San Francisco and Washington, D.C., saw growing bedbug populations this year.

Ohio continues to be a hotbed of activity, with three of its cities making the top 15.

"Bedbugs continue to increase their presence across the U.S.," said Stoy Hedges, an entomologist with Terminix. "While major metropolitan areas are most at risk, it is important to note that bedbugs have been spotted in cities and towns across the country."

Terminix, the country's largest provider of pest control services, has seen an increase in the prevalence of bedbugs in most states since releasing its first bedbug ranking in 2010. The company expects bedbugs to continue to plague the nation this summer as travelers encounter the tiny pests in hotels, airports and public transportation.

"Bedbugs can cause itchy welts and rashes, and may go undetected for months in a home or business," Hedges added. "It is important for consumers to know the signs of an infestation and to have their home inspected by a professional if they suspect a problem."

Terminix offers these tips to slow the spread of bedbugs:

  • Check hotel headboards, mattresses and box springs for bedbugs and dark blood spots.
  • Hang all clothing. Leave nothing lying on the bed or furniture.
  • Avoid storing your clothing in the hotel's furniture drawers.
  • Store suitcases on a luggage rack as far from the bed as possible.
  • Vacuum suitcases when returning home, and immediately wash clothing in hot water.
  • Between trips, store luggage in a sealed plastic bag in a garage or basement, away from bedrooms.
  • If you suspect your hotel has bedbugs, ask for a change of rooms.
